One of the most attractive other rarities found in this area — apart from the orchid Spiranthes romanzoffiana — is a happy group of Red-breasted Mergansers (ABOVE) with her brood of 7, leaving the shoreline in the background to seek safety on the open water as we approach during the start of this year’s surveying on the west shore of L. Conn. The shoreline shown behind the ducks used to be a very popular area for the deposition and growth of Spiranthes romanzoffiana. However recent Winters have been very wet and very stormy and the shoreline seen this year is markedly different from previous years with a sandy grassy shore replaced with a much wider and significantly stony shoreline. The stones range in size from heavy cobbles (30cm +) to numerous smaller boulders and pebbles. The area Spiranthes seedlings used to establish themselves is now more stony than grassy and not an attractive site for the orchid. Any seed washed ashore will be washed away by the outgoing wave..Existing orchids from several years back may now be buried under heavy stones and no longer able to emerge? But this was our first day here and maybe more will be found in later rounds? (Final Surveys up to mid August show no improvement! But, other areas have compensated)

Early Detection:First plant of the season, very small, hidden in low vegetation, only found after detailed search of the habitat. This was a grassy bank on the shoreline at the NE corner of L. Cullin. A few others were seen in this area.These plants are hard to detect at this stage but it is made easier by experience of their favourite places — such as we have over 5 years in this area. They also normally have significantly yellower long thin leaves. The bud often has a paler softer green than surrounding vegetation and this bud, even when small, has a very characteristic appearance and uniform colour. i.e there is no white or red (Marsh Orchids) showing in the developing flower. Plants without buds (rare) are almost impossible to detect at this stage.
LEFT: Main area for early flowering S. romanzoffiana:This specimen was one of a group occurring in a small island of rocks, sand and stubby trees (mainly Bog Myrtle), that provide them with the substrate and shelter to allow initial plants to germinate and then survive for many more years.This image shows a more visible specimen and the typical sandy areas between boulders and vegetation. A group of 4 ‘family’ Spiranthes survived here for 5 years and now a pair of ‘twins’ is recurring for its third year. The bare sand and low level vegetation makes these plants easier to see and record. Similarly areas of flat flooded grassland (popular with Spiranthes) also make the plants easier to detect. However, in many locations S. romanzoffiana choses to grow in rough margins with dense overgrowth and these areas need to be searched carefully at this time of year to ensure that hidden specimens are found.
a) North East Bay Lough Cullin Car Park 1 (south):A quick visit here on the way to Nephin and the west shore of L. Conn. It was great to see a large number of specimens emerging. (This was the site where, last year, inadvertent damage was caused on the site.) 32 specimens were recorded in a very short time with a considerable possibility that these numbers may increase naturally or decrease through people pressure. However, the NPWS and Coillte are aware of the issue and no further cutting will take place in the area.

a) NE Cullin, 1st Car Park.Starting off with a new assistant, our Son, with a very early start and finish due to heatwave like conditions that made it hard to stay out in the open after noon! The first target was the southern car park on L. Cullin. This is the area that had been accidentally cleared in 2020 but was showing good signs of regrowth on our first survey. We suspected that there might be many more today! I left the raw recruit to do the slogging whilst I went off taking photographs.LEFT This Car Park area has a consistent occurrence of S. romanzoffiana at both ends of the beach. At the southern end (where this photograph was taken) 12 - 20 sturdy specimens routinely occur in low undisturbed vegetation at the margin of the bay or around big boulders at the top of the strand.RIGHTThis is a sample from the recovering north end of the beach. Our trustee accountant located and marked 45 specimens which is a good increase on the numbers seen at the first survey on the 5th July (21romz/1a) It seems that the damage caused during last years season has been more than repaired and both the orchids and their guardian Myrtle bushes are regrowing rapidly!Spiranthes romanzoffiana (AKA Irish Lady’s Tresses) is a resilient species and can quickly recover from damage. Also, in this instant the habitat damage was limited to cropping the Myrtle, Alder and other bushes BUT no effort was made to uproot the root stocks thus allowing for a quick renewal of the habitat this year — maybe even richer area for the orchids in years to come. The owners have agreed not to alter this site in future… and many thanks to them.Perhaps it would be worthwhile providing information regarding the value of the natural heritage occurring here as this is one of three beaches on east L. Cullin very popular with holidaymakers in hot weather.Rest of L. Cullin: Because of the hot weather and the secure habitat of the adjoining NE bay where very large number of Spiranthes annually occur, this site was left for a future visit as the plants were unlikely to be damaged and the full flowering season had not yet arrived (See 21romz/4a BELOW)Instead a corner of L Conn and all of Knockmore Bay was searched instead.
b) The South east Corner of L. Conn:There are two potential sites here, one very poor and the other disappointing! BUT, hey, we visit them every year as part of routine. There is a section of coast between Pontoon and Knockmore that is largely steep rocky shore with suitable sites for Spiranthes only occurring at Schoolhouse Bay. This looks attractive but we have never found Spiranthes here — perhaps the shoreline is too sandy? However, a known site further north has proved not so disappointing this year. c) Knockmore BayThis is a known Spiranthes site where a DNA study on the species was undertaken many years ago. Since then the site has often had low numbers of specimens for one reason or another. This year we were pleased to see two sites on the bay flourishing.The first site was on the south shore just inside the obvious peninsula almost blocking the bay that was first explored last year; the same group of orchids were there again this year. This was a somewhat unusual site with many of the orchids well sheltered under lush Alder bushes adjoining a flat sand or bouldery shore with only a few specimens out in the open.d) Knockmore Bay North and WestA lightly grazed site where orchids and cattle seem to survive in harmony. Numbers in past years have been low or the water level has been too high — with sad orchids flowering in the water — but this year orchids were more widespread and more abundant.There are two sub-habitats here. Firstly, a fishing harbour with a large wet meadow which seems very occasionally grazed. Numbers here were increasing and, though some eaten specimens were found, many were intact and flowering.The other habitat was a narrow shore line fenced off from the harbour and stretching out onto the exposed boulder coast beyond the mouth of the bay. This is really a storm beach with many massive boulders bigger than present Winter storms could manoeuvre — possibly washed out from ice sheets of earlier times?
e) Headland north of Sandy Bay
Sandy Bay is a diverse beach/marsh/wet pond/rocky area with a range of varied habitats which yielded a good number of Spiranthes records last year, This year the beach was affected by very hot and dry conditions. Numerous dried up Marsh Orchids could be seen scattered over all the marshy areas but none of the shore edge Spiranthes seen last year had yet emerged — another count will be needed? However, a small colony existing on a flat rocky headland pointing out into Lough Conn was starting to emerge in smaller numbers.

A bit of a disaster, but…
This species we are dealing with is a passion we have shared for 15 years. We can be obsessive but we have seen how last year’s damage to a habitat can be repaired and the Irish Lady’s Tresses will bounce back. But, this Spiranthes plant is part of our natural heritage and diversity and none of us want to see a country with its nature reduced and industrial agriculture taking over the family enterprises? Spiranthes romanzoffiana — named in Alaska by a servant of Govr. Romanzoff, first recorded in Ireland in 1810, and now (we believe) maintaining its stock from seed blown across the Atlantic — is sign of a vibrant healthy environment that is clearly thriving here in North Mayo.Yes! One of the sites we visited today (The Lagoon) has been partially cleared — probably unknowingly? Spiranthes is one of the few large plants protected by a Flora Protection Order of the Wildlife Act. It is not permitted to damage the plant or the habitat in which it grows; but not many people know that! Many farmers would not be aware of its presence on their land and that is why we do yearly surveys here.a) North east L. Cullin…But, the good News first…. Our first survey today is an outstanding conservation story with the plants persisting and often growing in numbers. Of course they are vulnerable to Summer floods but this year, ironically, the weather has been almost perfect for them and for their observers. They are not too vulnerable to the Sun but we have had to start early and finish early in recent exhausting weather.We have recorded a very high number of specimens in the square shaped broad sandy bay, near Drummin Bay, one of the most northerly points of L. Cullin. This bay is full of sand and is also full of this Orchid. It has been a pleasure to survey them and we trust that regular oversight will help conserve this delicate habitat at the north end of L. Cullin!Conservation Recording technique:We use a trusty reliable hand-held GPS device with a high sensitivity EGNOS enabled receiver. This enables us to collect a large amount of data and quickly transfer it to charts to record and display how a species is surviving and how its distribution may be changing. An accuracy of 3 metres is quoted but the most useful feature is the ability to see (in a confusing environment) whether you have already recorded a ‘new’ plant! Patterns also show up very well on GPS and S. romanzoffiana very much delivers curves and patterns reflecting water features etc. This helps verify records or suggest another check might be required.Todays Result:This was a quick operation that needed to be done in a business like fashion. Fortunately most of the orchids are growing on open ground and over the years we know where they hang out. Some disappear, new ones appear, and old family groups (3, 4 or even more) show up on our maps year after year.This year yielded: 173 Spiranthes romanzoffiana. This is separate from other good numbers in the Car Park bays further south. Also a preliminary survey at the beginning of July has been absorbed as this later survey shows many samples within the zone of error of the system. We define this as at least 5m away from any other previous record.This is the largest number we have ever recorded in this bay and if this pattern continues we may well have the largest Conn/Cullin overall population of this species ever recorded. However all this may change if disastrous changes in weather occur as they have often done in August and September. So, we are keeping our toes crossed in the deliciously warm clean sandy water!
to be continued….
As we write some very interesting records have been obtained from the east shore of L. Conn and the north shore of L Cullin.These will bring the total reportage from the twin lakes to well in excess of 600 specimens, all fully logged and mapped. This is on a par with previous years final totals and we have not yet completed all our surveys.This is good News but not exclusively as one northerly site has had a major part of its habitat seriously damaged with loss of more than half the number of Irish Lady’s Tresses to be expected there.

a) Coastline 1.5km S of Wherrew near Inishlee Island.
This was a quick but very successful trip yielding 135 fine Spiranthes specimens. The shoreline walk from the Pumping Station had no records (1 or 2 in the past) but numbers started to build up as the kidney shaped island just off shore was reached. None were found on the island in the past but only the causeway was searched. North and south of this causeway orchids were found growing alone on short shoreline grass or in the scattered Alder Woodland backing up this shoreline. These young trees were much taller than last year but the number of orchids had also gone up also — though the rapidly growing ‘Alder Forest’ may eventually smother them.
The largish flat area south of the causeway was a Spiranthes paradise with numerous paired plants, triplets and even a foursome. They were in perfect condition, in full flower, and no sign of any damage from weather or grazing — a perfect location for a Spiranthes Reserve?Lough Conn: West or East?Initially when we first started surveying L. Conn the East shore, including this location, was very fruitful. In recent years many more cattle (and horses) have gained access to some of the shoreline though landowners have clearly made efforts to keep stock off vulnerable biodiversity land. This has paid off in spades at Wherrew and L. Conn and Cullin must now hold the record for the greatest number of Spiranthes plants anywhere in Ireland and Scotland!Loss of Spiranthes on west L. Conn:WildWest.ie has spent much time seeking out this species all along the west coast of L. Conn particularly from Massbrook to Gortnorabbey — with spectacular little return. Five years ago we postulated the theory of windblown re-seeding of Spiranthes from America based on the perfect patterning of emerging plants a fixed distance from this shoreline and a fixed distance apart. These have now died out as the shore becomes stonier!

We are reporting Water Levels as metres above base of measuring gauges. Gauges are at different altitudes (O.D. Poolbeg, Dublin) So whilst the 2 sites are very close and connected the WL reading differs at Pontoon and Corryosla. Check water Level HERE. Levels shown above are LOW. A modest increase of 0.5m will flood many of the sites shown.
a) Roadside Bay SE of L. Conn… First stop today (21romz/6a) was disappointing with none on the large sandy shore to the east of the bay — a former happy site for Spiranthes. Similarly on the NW running stony shore on the far side of the bay — though this shore has never yielded records to date. A few specimens did turn up near the roadside parking in reeds that occupy much of the west of the bay. Some records on northern rocky point need to be checked still!
b) South of Pontoon Bridge…Thankfully this was, and is, a most rewarding site with 133 S. romanzoffiana quickly found on the west side of a large rock and grass headland pointing due south into L. Cullin. Most of the records occurred on this shore or in wet Bog Myrtle fields behind the shore — obviously flooded during the off-season! Beyond the point lay more suitable habitat but a fence heading through the bay indicated a change of management and heavier grazing to the east meant no, or very few, Spiranthes had survived until the major site at Drummin in the north east corner of L. Cullin.It seems that a consistent but very low level of grazing, and a rough terrain for cattle, provided the opportunity for Spiranthes to thrive along this west facing shore from Pontoon Bridge to the point. This area has over the past few years been consistently reliable and some off-lying Islands that are not grazed at all will always form a reserve for this species subject only to climate change and flooding — which has not yet happened this year?
ABOVEThis small bay contained a good proportion of the records. We have never seen so many specimens of this orchid so close together; it is like a scene from the species heartland in the USA. This shore contains much smooth sandy grassland behind a line of boulders with embracing headlands either side that would not be easy for cattle to travel — leaving the orchids time to flower
ABOVEA close up of part of the colony with 11 specimens visible. (Be sure to ENLARGE this image.) This shows the clean grassy gently sloping shore that Spiranthes love. This species will not grow without some clay present and the barrage of boulders seems to protect this area. Erosion of nursery beds is probably the basis for loss of records in habitats that have been altered by weather?
c, d) Massbrook Harbour/Forest shore, L. Conn westThis is our third occasion search these two adjoining habitats. Both had been good locations up to 2019 but both have been disappointing this year. The cause seems obvious. Unlike the site shown RIGHT, the two Massbrook locations had very flat shores which had clearly been scoured over past Autumns, Winters and Springs, leaving a continuous zone of gravel, cobbles and medium sized boulders with only very coarse sand and gravel between. Kicking with a heel showed no depth and no clay or silt for Spiranthes seeds to settle in. By contrast 5 years ago when ribbons of Spiranthes were see, the shore was ‘gentle’ with a wide band of sand close to the waters edge. This seemed to provide the ideal conditions — no longer present — for S. romanzoffiana to settle and thrive.The suggestion that the western shore was preferable to the eastern shore seems implausible; both sides can have orchid numbers depending on shore condition. The current abundance of Spiranthes in certain areas on the east shore of L. Conn simply reflects areas that have been neither disturbed or grazed and met the species requirement for shelter, suitable soil (with mycorrhiza), and abundant shelter such as young Alder trees.
e) Gortnorabbey, West…
This Abbey and Harbour in northeast L. Conn is a means of access to a small lagoon at the north of the lake. Damaged this year, ‘The Lagoon’ was a fertile incubator site for Spiranthes having around 100 specimens over several recent years… (See /5c above)At the other side of the harbour there is a wetland with low areas of grass flooding in Winter as evidenced by the protective piles of boulders and the sandy washed out pans among lower areas of grass and vegetation.In these areas a few Spiranthes grow — just three this year. However, what is interesting in the picture RIGHT is the close up of the reproductive behaviour of this species.Lateral Bud…The dark green bud is the way groups of 2 - 4 Spiranthes develop. These buds start to develop as the plants flower and will continue to develop in the Summer and Autumn. We recorded this plant as a single specimen but it seems that another shoot existed, probably from last years lateral bud? This year so far has been kind to Spiranthes but it may change and seeds developing in the Autumn may again be destroyed. If so, lateral buds will enable this species to survive and multiply.
f) Sandy Bay, middle East Shore, L. Conn. Half sandy, half rocky…
If you look at a map of east L. Conn you will see a long horizontal shore ending in a sharp point with Sandy Bay (proper) protected behind this. Both these features are very relevant to the Irish Lady’s Tresses as it occurs in both places. It seems does strange the way this species occurs on very exposed barren shores?LEFTThis is an area of what can only be called karst, a lot of it is bedrock with distinctive hollows in the exposed surface. It is limestone — though other rock types are common around these lakes. This specimen, and up to 20 more, grow in lush grass flourishing in areas of this barren bedrock and seem to have formed a marginal attachment to whatever small pockets of soil that can be found in the solution hollows. D. cruenta has a similar niche in The Burren. Many orchids like lime but S. romanzoffiana is singularly missing from the Burren — Ireland’s best known uplifted limestone area!RIGHTSandy Bay is a large beach area of sand, flooded peat with many waterlogged shallow pools, and dry islands (flooded last year). All under the harsh conditions of a long Summer heatwave which has lasted through all survey work to date.Spiranthes adapts to all features of this site, bare sand, dry lagoons, flooded marshes and islands. First image is on a settling dune; the second is higher up in an established island. Last year this plant was in water! On our last visit (July 20th) none of these orchids had emerged — just some of the rocky Point specimens!

a) Terrybaun to Massbrook Harbour, L. Conn.
This 2 km of shore can be readily walked with low water levels (<0.35), with some difficulty as the level rises, and impossible as the shoreline trees get inundated.As you can see, today, it was very easy but, unfortunately no orchids were found. Up to 2 years ago Spiranthes was widely scattered along the grassy zones such as RIGHT. Typically the orchids sheltered among the small Alders between the storm beach and the foreshore. None were detected here, presumably, due to obvious severe exposure over the past couple of years leaving a lot of the shore bare or otherwise covered with numerous and large boulders. This is disappointing as, though often difficult to count, this shoreline would have contained up to 100 specimens during our period of surveys.This shore has several small, bays like this one, but all areas that formerly held populations are now high above water, very arid, and heavily covered by boulders. We believe these natural factors have eliminated existing plants and reduced the suitability of the area for future seedlings — as discussed ABOVE in regards to the Massbrook woodland shore.
Filling the gaps… this is what we do when we have visited many established sites On L. Conn/Cullin. This was a new site for us and a very rewarding one. It is facing south like many successful sites on both lakes? It is an idyllic shore with plenty of shelter from large boulders and offshore shallows and a marshy or rocky back shore with plenty of shelter in the form of lush grasses, small Alders and Bog Myrtle. Many plants were recorded here, often quite large and mainly in clusters as shown.
Three Groups of Spiranthes:ABOVEAbove the rock and in front of the Bog Myrtle lies a bed of about 12 Spiranthes. The bog behind is quite wet and spongy even after 2 months of drought.LEFT ABOVE:A slightly different habitat on the lake side of the path showing a string of orchids heading out to deeper water. The widespread presence of boulders, smaller erratics, and sturdy vegetation probably affords a level of protection to this shore which otherwise might be vulnerable to erosion and deposition of a thick layer of stone along the shore.LEFTTwo of the best specimens seen at the top of the beach and at the edge of some sturdy Alder trees.

Conservation & Recording.
We count Spiranthes romanzoffiana to monitor change. With a rare species like this large numbers can change into smaller numbers and then disappear. Species loss can be due to natural events or human intervention. Both are present on these two lakes. We don’t want them to disappear! Ireland is the only country in the EU that has this species. Lord knows we are missing many European species due to being an island. The only other ‘European’ country that we know that has significant numbers of Spiranthes would be Scotland. In Ireland the Conn/Cullin complex is undoubtedly the largest occurrence of Spiranthes and we would be very surprised to know of higher numbers in Scotland? We would love to have reports and numbers for Spiranthes romanzoffiana in that country. They have a very large area of suitable habitats along many parts of the west coast and the islands.Biometrics: Biometrics is the science of observing change in status of an organism be it in occurrence or in vigour and viability. For example, many Irish specimens survive by vegetative reproduction — so Summer weather does not affect them so much as plants trying to reproduce by seed. These face the whole rigmarole of growing and flowering, fertilisation, seed maturation and dispersal locally or far away, finding a suitable seed bed, forming a mycorrhizal association, developing an underground energy store (tuber, enlarged stem..), maturing over some years and then flowering again. It is quite exhausting! That is why secure undisturbed habitats are important. Fortunately there seems to be a ready source of fertilised seeds from the other side of the Atlantic; many of these may drop on Ireland’s west coast.Species Loss: This occurs where this chain is broken and irreversible changes happen to habitats so as to make them in-habitable. Changing from rough grazing to rye grass fields alongside lakeshores is a loss of diversity both in the diversity of grasses in mature pastures to the loss of certain key species (axiophytes) that need a wide range of features in their terrain to enable them to survive and compete with other less aggressive (tall) plants.Why keep biodiversity: A monoculture, be it in agriculture or forestry, permanently removes a wide variety of native plants and animals that have made that place special and part of our culture and natural history. It is what gives a Country character. Widespread industrial farming will lead to monotonous landscapes with few species and no rare ones. Keeping a naturally rich countryside can proceed alongside agriculture and meet everyones need for food, income and wild natural places in which to unwind. Support is available for this sort of farming and such farming and such practices will become more and more mainstream as Ireland and Europe work to protect the nature we all enjoy, conserve energy, and try to control climate change rapidly becoming a major threat to many countries in Europe and the World.
b) North Shore and St. Patricks Point…Leading to The Lagoon this area is often traversed but not separately recorded. Now, with The Lagoon habitat being reduced in importance this site acquires more importance. It is still part of one large area of extensive grazing but the Alders on The Point are particularly large and strong and provided secure shelter for some shoreline Spiranthes. Interestingly these plants were often paired and included some of the larger specimens seen. The presence of multiple flowering stems implies that these are mature plants with established ground infra-structure enabling them to sustain flowering for several years. Maybe there is a lesson here. For several good reasons cattle are probably better kept away from easily damaged shores. In a location such as south east of Pontoon Bridge (21romz/6b) the massive geology and heavy woodland in places naturally inhibits cattle from exploring rougher water edge sites which the Spiranthes love.St. Patricks point could be a place where natural biodiversity and beef production could work in harmony — but there is still a case for taking measures to keep the water pristine and clean as it has appeared all through this season to date? The location held 13 specimens but could hold many more as we did not have time to fully record the site… yet!c) The ‘Lagoon’, Tolans Bay, North L. Conn: Exploring Habitat damage… seeking a means to conserve a protected Orchid (S. romanzoffiana)Unfortunately this site, which has been a stronghold for this species for as long as we have monitored L. Conn, has been cleared and major unfortunate changes made to its habitat. Lagoons seem to form in series along this north shore with an incursion of lake water to form a pond, then water loving plants develop like the Spiranthes, Bog Myrtle and Alder. After a number of years the lagoons close over and become fully secluded ponds with a typical shallow constant water habitat and flora.With the exposed sand, numerous small channels, and shelter of many small bushes, this site was an ideal nursery. The pictures below show the past and present nature of the area. Some of the changes made to the habitat are clearly not in the interest of the orchid but can probably be recovered. The aerial view BELOW shows the site, previous cutting of the area, and the location of ALL Spiranthes seen this year. Previously the Blue Flags would have been mirrored in a more extensive pattern to the right. All the area from the Lake (at bottom) to the middle of this image held S. romanzoffiana over the years but with records mainly from the lake to the start of a band of Alders (dark green) and extending in this belt to the Right in decreasing numbers. It is the area to the Right of the recorded specimens that is prime Spiranthes habitat; it would make an ideal Spiranthes Conservation area.
BELOW:The damage as discovered. Looking north towards the house, the area to the right of the stream has been cleared, scraped, and no Spiranthes remained. In fact the only ones found are as flagged and the whole site shown in the Aerial View was covered.
BELOW:Looking north towards the house shows how this fertile ground has been leveled and left vulnerable to erosion. BUT, there are pools and channels remaining and undoubtedly certain plant stocks will re-occupy the area if no further alterations occur. The owners of this site could indeed benefit from this rarity that is very much a Mayo specialty
LEFT:Here we show the two sides of the stream. To the west the habitat is undisturbed with a healthy stock of Alders and a lush lower flora including the Spiranthes.
RIGHT:A wider view of the area that was traditionally filled with a stream, small channels, shallow pools with scattered small and medium bushes which provided good protection for the Orchid and its Habitat.
We believe this is a valuable Natural Heritage area with a worth akin to classical man-made Heritage and the culture and traditions that are unique to Ireland. Spiranthes romanzoffiana is a Celtic Botanical Symbol found only on this side of The Atlantic in Ireland and Scotland.
A quick reference to The Geology Service (gsi.ie) reports Silurian granodiorites in this area. This is a seamless coarse grained acid igneous rock akin to Granite and associated with a plutonic darker shaded rock called tonalite — but this is not noticeable in the image below. They are, as suspected, a hard formation bordering both sides of south Pontoon bay and clearly associated with S. romanziffiana!
These smoothly polished bedrock elements immediately caught our attention as they are identical to the habitat found on the other side of this bay where ice sculpted bedrock also has huge erratics on its back. The west, north and east borders of this bay (and Knockmore) are bounded by this geology. Ice movement probably formed the modern channel for water from L. Conn to L. Cullin. Whatever the cause we have found that these low ‘roche moutonnée’ attract Spiranthes. They love to establish themselves beside one — like a mouse sheltering from a cat! A more pedantic explanation is that these ancient strata are immobile whereas most large rocks on the shore can be moved. These can be boulders or massive erratics that are impossible to move — apart from ice! There are many erratics in the area but they tend to be towering cuboid blocks with rough edges that are dumped in the landscape as the Ice Age ended.

This beach was a small Alder Wood that helped provide protection from Winter storms. This been removed and the exposed sandy bank is now very vulnerable with large scale land erosion being a distinct possibility. Again, quick re-growth could help avoid this.
b) West side of Bay leading from Pontoon Bridge southwards.
Well buried Spiranthes flowering with plenty of support from Bog Myrtle and Vetch. These were difficult to see. In a quick re-survey of the 3 Car Park sites few new plants were added but the South Car Park still had a good show of young Spiranthes successfully re-colonising an old site. Information for the Public could be useful here but they are also thriving on their own with little sign of footfall damage.
Gipsywort Lycopus europeusNothing much to do with Spiranthes but we were dying to take some photographs.

a) South Lough Cullin: This is an area around the R. Moy outlet and adjoining the Railway south of Foxford. It has a suitable habitat but only occasional has produced S. romanzoffiana, due to grazing along the coast both north and south of the Moy. Records are few and today no plants were detected.b) Derryhick Lake: With a visually appealing shoreline this areas has been surveyed often but NONE found.* c) Bunduvowen Lough: (Not site referred to Below.) Only surveyed this lake because of strange report in the online record (Below), dating back to 2002… Heavy shoreline vegetation with no suitable shore.Bunduvowen, L. Cullin. G221018. 4 August 2002. 14 plants.ALSO: Drummin, L. Cullin. G2304. 3 and 4 August 2002: 400 plants, FH. 2 August 2003: 284 plants, FH. in early August 2004 Gerry Sharkey visited this site. FH had asked him to estimate the number of flowering plants present. His "very conservative estimate" was 300 plants. Plant growing with Neotinea maculata and again with Sisyrinchium californicum, the latter in abundance. FH learnt later that Anne-Marie McKee had discovered this site on 26 July 1999 when she found six plants in flower. On 25, 26 and 29 September 2002, FH returned to this site to examine the dead spikes for seed capsules. Eventually, after a very thorough search, 224 of the 400 dead spikes were located but not a single seed capsule was found. This name is used (in Google Maps) for a small lake in the hills above the west shore of L. Cullin. The townland running down to the shore is also known as Bunduvowen and this is clearly where the author (above) referred to. But the information, contained in an old report, only became clear on subsequent reading. It has not been possible to visit L. Cullin shore yet; Spiranthes could well be still there. (They are — 2. See DAY 11 BELOW)Some of the numbers reprinted in the blue text above very much match our present research as does the presence of Sisyrinchium californicum but we were very surprised to hear of Neotinia maculata (a Spring flowering species) found growing alongside S. romanzoffiana? We will look for them next May!d) Levally Lough: Success! This species used to occur widely along the north shore Car Park area; now they are confined to small dense population in the NE corner of the Lake where we saw 22 specimens which had obviously been thriving until recently flooded!e) North shore of Errew Peninsula, W. Lough Conn. A difficult site with the orchids exposed to harsh north winds and wave conditions. We were a bit late in getting around to checking them out this year and our count of 15 is low for the area. We have had much higher numbers in other years. The Images RIGHT are from Errew and show a a much battered Spiranthes but apparently showing the initiation of seed production. Many of the Spiranthes here were in groups of 2 or 3 indicating, perhaps, that they are sprouting from a previously established enlarged root?
HabitatsSandy Bay has 3 distinct habitats, The Sandy Beach and Marsh (RIGHT), the long barren stretch of gently dipping bedded limestone (FAR RIGHT) and the remote rugged karst point to the north of the bay.
and Habits…3 prominent beach species. Many species seek shelter on raised ground in the beaches. Tussock (LEFT) features the beautiful Grass of Parnasus Parnassia palustris in a location often favoured by Spiranthes.
This wall of Spiranthes was typical of today’s research — pushed back into the densest vegetation rising water levels could reach. This large area of back-strand was level with several deep pools and meandering channels that reached into even the highest areas of vegetation and deep quagmires. It shows how this plant seeds itself. Expected further new specimens along the main channels and islands were not seen on this visit.
a) Cloghans Bay, E. Lough Conn
Cloghans Bay is in the northern half of L. Conn. It is a shallow meandering bay with a very extensive coastline. The coast is largely devoid of Spiranthes as it consists mainly of grassy islands and sloping wide shores. Despite its protection the area has only one significant colony of S. romanzoffiana on a headland jutting out into Cloghans Bay near the main fishing boat landing area.

c) Bunduvowen, east side of L. Cullin
A small lake, a community, and a jagged coast onto L. Cullin, defines this area. It was identified from literature from the Royal Irish Academy c. 2004. The shoreline of the site is very suitable consisting of many small bays divided by rocky promontories. After much searching 2 specimens were found on the shore immediately north of Bunduvowen in a suitable marshy bay. They were a lucky find as we had combed the same area on the way out. Accordingly, permission was obtained to search a western shore from where the river enters the lake up to the point. A very interesting area and local help was very important but it seems we were probably too late. Plants were disappearing rapidly. This was the first indication that our survey for 2021 might be almost over… suddenly!
RIGHTNot the best of photographs but an important one as we are not sure there have been any records for this location since 2004.It would seem to be an ideal site with a variety of habitats from short grassy shores on sandy bays to rocky alder bays that this species loves, to the edge of flat wet fields and marshes where they can thrive if not grazed
a) The 3 Car Parks at L. Cullin coming out from Foxford
These are 3 lovely beaches lining the road from Foxford to Pontoon where it comes close to the north east shore of Lough Cullin. Perfect for kids and weary adults to relax in peace and good clean water. In all our traveling around Loughs Conn and Culllin we have never seen bad water — always a pleasure to relax and work there. And that is not something we would say about many more midland lakes!As family people, with a water loving dog, we always have to be careful that the waters we go to are safe for swimming in. And in north Mayo, they always are. Of course there may be very occasional instances of green algae pollution but never have we seen an outbreak of the horrible and deadly cyanophyceae pollution that is only too common elsewhere. So a big vote of confidence to Mayo County Council and their Water Department.However, our purpose in traveling all around these lakes is to observe and record the orchid, Spiranthes romanzoffiana, as these lakes are prime territory for this species. Happily, as this survey comes to an end we can record our biggest ever count of this beautiful orchid, also known as Irish Lady’s Tresses. Mayo could well be the European Heartland for this unique species — indeed Ireland is the only Country of the EU in which they occur and we probably have a larger occurrence of the species than Scotland, its only other known haunt this side of the Atlantic.
Something to be proud of…
… and we are but we should look after them — while we have them. Mayo could be a perfect conservation location for this species though it may, inevitably, migrate further north if Climate Change and global warming is not controlled. It can be our unique litmus test?
b) The Botany of the 3 Lough Cullin car-parks.
Apart from the social and heritage value of a pure clean and healthy environment to us, it does also allow plants and wildlife to flourish as they have always done in a wild and natural Ireland.Interestingly these beaches do offer some singular benefits — especially the place we call a Nursery —where S. romanzoffiana seems most likely to produce seeds!1.At the upper edge of CP 1 (the first Carpark you will meet coming from Foxford) there is a small flat area like a tennis court but with many small trees (Alder) there. These protect the Orchids and the Orchids protect the beach. If a mistake happens and their habitat is damaged the protection afforded to this very rare plant can be invoked and any accidental damage done to their habitat can be repaired. S. romanzoffiana is one of the few plants in Ireland whose habitat is protected by law — as is the species itself. Isn’t that amazing!2.It seems that people and this orchid can survive very well together. We have often been amazed at how this species can flourish in what can be a very busy Summertime beach. It would seem obvious to fence and ward off part of the shore but that might be counter-productive?3.Further out in Drummin’s Bay (where very few people go) there are a hundred more Spiranthes appearing and flowering and reproducing every year unhindered by mankind and cows! But secure fences are vital as we have often seen hungry cows eyeing up the wet shoreline and strand where the orchids thrive..
A damaged plant in The Nursery but it is recovering and growing upwards and its roots, stem and seeds may still develop.
Lateral Buds (the oval shaped leaves) seen here are the vegetative way this plant survives — no seeds!
LEFTAn unusual variant. This plant is producing buds and flowers at every node when it ‘should’ only have a cluster at the tip of the flowering stalk.These occur about 1% of the time at the end of the season and is the result of a simple genetic ‘error’ Other orchids would naturally do this!
RIGHTAnother very healthy plant from the Nursery with a good length of flowering stalk and still green and very healthy. We hope that this plant might go on to develop seeds if weather is good; more information later.
RIGHT: On the mid west shore of L. Conn at Sawmill Point, there is another long gently curving stony shoreline with a backdrop of Alders, Bog Myrtle and Royal Ferns — a typical Spiranthes Habitat. This yielded some specimens but not as many as in earlier years. Like much of the west shore of L. Conn this shore is now stony with fewer sandy/grassy patches for the orchid

September, and into our final Recording trip…
The Summer has flown and it seems as if we have seen the last Spiranthes for 2021. Following our initial survey of the north shore of Bunduvowen (2) we got an opportunity (facilitated by landowner) to survey the wast facing coast north of the Bunduvowen River. A very suitable site, lightly grazed with numerous rocks and bushes for Spiranthes to hide under; but none were found! we acknowledge the work of earlier workers and the Irish Naturalist Journal in bringing this location to our attention. The precise location was not given so we had to rely on our experience in finding the plants. First day was successful; today was unsuccessful. This area will certainly be a priority of a less intense survey (We are getting old!) in 2022…b) Victoria Bay Names are a problem around Lough Conn and L. Cullin; how many of them are widely known nowadays? We are using this name to cover and area north of Massbrook Point and going up as far as Sawmill Point and the distinctively pointed bay near Tonacrock. All of that difficult coast has been walked at least once apart from a stony shore heading towards a fishing area and some holiday homes. This could have yielded 10 or 12 records but we had to abandon it today as access, without undertaking very long walks, was difficult. Also, the northern part of the shore, formerly good, only supported 7 specimens in about 3km of walking (there and back) so numbers missed were probably very small.
a) Inishlee, NE L. Conn, September…into our final Recording trip.
This is one of the areas around the Twin Lakes (Conn and Cullin) where we recorded over a hundred flowering S. romanzoffiana. These spectacular occurrences led to our largest every level of records. (21romz/5a) The area can be placed by Nephin looming across the lake and the little kidney shaped island and isthmus featuring off shore from two colonies of Spiranthes. Today was a return visit hoping to see many healthy fertile orchids still thriving — but a little pessimistic also.
Unfortunate loss of stock:Inishlee is a salient pointer for two separate colonies of Spiranthes. The lower photo (RIGHT) shows the shoreline and the hinterland behind it south of Inishlee. All this area from shore to large background bushes contained many orchids. (See Day 5 above)Sadly, all this shore, which had not been grazed (i.e. cattle had been excluded) until now, has become a sad zone for the Spiranthes. Of the 135 found a month earlier only two could now be identified and both of these (BELOW) were showing damage by grazing. Ideally, biodiversity and conservation should protect sustainable farming and Nature; if only there was way this internationally significant extremely rare plant could be protected around the Lakes! All it would take would be a selection of plots of land (1 or 2 Ha) around several parts of the Lakes to be effectively protected year round — and for landowners to be supported — year round?
LEFTTwo stragglers from a large colony of Spiranthes south of Wherrew. These were all we could find on our second visit and damage to plants and site is evident.Both plants seem healthy and there is no fatal damage done. If left undisturbed they could go on to develop seed especially with the benign Summer/Autumn Ireland is enjoying.
RIGHTInishlee Islandsituated in NE Lough Conn is a very low island but does (quite likely) afford a degree of protection to adjoining shorelines north and south even when the narrow mainland connection is flooded. Such shelter would account for the shallow grassy shores with only modest boulders.
RIGHTThe main shore at Inishlee, taken from north of the isthmus showing both the beach, the grassy area. and the dense Alder growth that all seemed to suit S. romanzoffiana at the start of the season.However the shore is very prone to species loss once grazing is opened up and, regretably, this implies full year round protection as vegetative reproduction is active from now through to next Spring.
c) Bunduvowen Point…Anxious and shy, at the same time, we were keen to complete the rest of the suitable Bunduvowen shoreline for future recording! A warm welcome and some helpful guidelines soon had us on our way. Inevitably we spend a lot of time trudging along stony shores — and we look on them as public access? But, sometimes you have to ask for access. We were so delighted with the help from a local man in how to get there and… to mind the bull! Both of which we adhered to and enjoyed a pleasant hour on a very suitable shore line which, we expect, at the right time of the year might yield many healthy flowering Spiranthes. Today was too late but the knowledge and the contacts makes our work so much easier. Thanks to all who have helped us!The problem of dying orchids:We have a policy of recording every orchid seen except where our records show us that a specimen could be withing the tolerance of the GPS and, therefore, the same plant — even if it looks different to our memory. That is why we try and visit every location at least twice a season and use tricks, like different coloured markers, to differentiate plants seen on different days. Every plant that emerges is regarded as a record as long as it emerged, was recognised, and was far enough from any other specimens to be sure it is a distinct plant. So, the record from Inishlee will read 135 — even though only a few are left. Their roots and lateral buds are still in the ground!
RIGHTFurther away from the water small groups of mature plants were clustered together in much heavier vegetation of Alder, Myrtle and Great Burnet
Damage to ‘a Spiranthes habitat’ was first observed this year in a place we have christened as The Lagoon over the last several years. It is north of the Deel River In Tolans Bay, an area that feels the brunt of southerly winds blowing up L. Conn. These lead to bursts over the shore where it is not protected by an impregnable wall of Alders. The water used to enter through a very limited channel and remained as a a wet lagoon for months afterwards.
Towards the end of August we visited a couple of known locations around Sandy Bay. But first a visit to Brackwansha a bit to the south — an area of lagoons, marshy
patches, and raised sandy banks — very like Sandy Bay and The Lagoon also visited today. After surveying Brackwansha a full coastal walk was made around the point
and along the north facing shore to a known site at the entrance to Sandy Bay where numbers were reducing. It’s a very arid and exposed karst site.
The small table below shows the numbers found every year since site was identified:Date:Count:Comment:19 July 20181421 visit; The best ever.23 July 201938The weather/visits6 August 202058A fairly healthy count for August24 July202112Much of site has been cleared!It should be noted here that Spiranthes romanzoffiana (Irish Lady’s Tresses) is a species protected by law under the Wildlife Act. It is not allowed to damage or remove these plants or alter their Habitat. For more information visit this NPWS Site. (National Parks and Wildlife Service of Ireland.) Site Damage has been reported.
a) Brackwansha to Sandy Bay… the long way!
ABOVE: Back strand at Sandy Bay with Spiranthes lining flood ways.
21romz/12a and 21romz/12b
c) New NW site L. Cullin:
Today was our second visit to this site discovered on Day 7. Nothing more to add except that 2 more specimens were reported to us on the west side of the the stubby promontory jutting into L. Cullin. This is a very valuable addition to our collection of new habitats to facilitate early recording of emerging specimens in future years; late July is the time to get the bulk of field work done!
e) Drummin Bay Spiranthes stronghold:
The team split up here with one working on monitoring existing flowers for possible signs of seed production and variants. It has been a disappointing year for sexual reproduction with no indisputable indications of seed production on a significant scale. Further research will be reported in the Autumn (in a different Page) comparing the numbers of seeding plants from 2018 and 2021. We look forward to getting this done.The other recorder simple studied the area outside the places where our previous large numbers were collected. 2 additional records were found using GPS to separate the old and the new records. These will be added to the Map and we hope to be soon able to produce a live map of the success of this species in Conn and Cullin in a GPX or JPG. format.
d) Knockmore Bay, NE corner.
Whilst we have surveyed this bay thoroughly in all years we have missed this place where it seems there was a good collection of S. romanzoffiana in previous years. Indeed, it is a very suitable habitat and little disturbed apart from the pulling up of some shoreline Alder trees. No Spiranthes were found, just some interesting Invertebrates, one of which is shown below.Shark Moth Cucullia umbractica is a western species in Ireland particularly found in Mayo. The shark name comes from a shark fin shaped projection behind the head of the adult moth.
Water Gauges: These large modern measuring devices situated in the lakes, or hidden on their shores, or reported in the WaterLevel.ie website, show the same information both in traditional pillars and, now, electronically. They enable fishermen to plan safe trips and they are vital in advising when rare plants and animals can be safely viewed. These gauges measure the changing water level in metres above the base of the staff. The height above sea level at any time can also be determined from the above website. A very useful service, much appreciated!
b) Sandy Bay.
Middle of the east shore of L. Conn south of Cloghans, this is a very attractive diverse area with many interesting species and good numbers of Spiranthes
a) Illanaghty Shore: This pointed headland guards a large bay north east of Pontoon. Formerly it provided a few Spiranthes, but none this year. However it is a delightful habitat with its stony northern shoreline and tree clad islands and the ever impressive Nephin looming in the background. A bit hard to get to but well worth the effort on a sunny day with the water level low. Has many suitable niches to harbour some Spiranthes but being a bit late in the season — with some very active horses roaming over the whole area — probably explains the absence of Irish Lady’s Tresses from this zone and many similar areas of the Twin Lakes.
These 4 images are all from Car Park 1. The plants are thriving!
b) North East Bay Lough Cullin Car Park 1 (south):A detailed survey from Sandhouse Bay to Massbrook Point. The MAP we REFER to is available from Inland Fisheries Ireland and it is a beautiful piece of work showing so many local names that can identify our orchid sites. Only two specimens were recorded on this walk and the rough headland to the north.c) Cuilkillew and Victoria Bay, north of previous site.Again a disappointing survey with on 4 spotted. This was a wide flat area of grassland and ponds but affected by low-level grazing and pulling up of Alder trees which were an important part of the shore. Not bouldery at all and might have been suitable other factors excepted.
