Irish Lady’s Tresses Multi year SURVEYS

2012: 30 to date! (20th. August 2012) / Photo GALLERY 2011 HERE / Maps HERE

2012: Plants are appearing north and south of the Lake!

Flowering specimens this year have been disappointing. These 2 from Annagh are the best we have seen. For our best Photographs from previous years, Go To (2011) (2010) and (2008)

UPDATE: 20th August 2012... 30 flowering specimens!

We are getting close to finalising our Spiranthes Count for this year. All the eastern shore and most of the northern shore has been surveyed. All know sites have been visited on several occasions by us and by some very experienced Botanists. We were pleased to be able to introduce some reasonable plants to some English botanists who havn’t met this species before!

Numbers are down on last year with Orchids so far missing in some important sites. Until the middle of July some areas were underwater and now (mid August) water levels are rising but none of the emergent specimens have to date been flooded. It was some relief to see the first specimens appearing belatedly on the 24th. July. These were at the south end of the lake where they have not been seen since 2008. Shortly afterwards they were found at their old haunt of Rossmore on the north shore and there are now 15 records from there. The wet windy weather does not suit this species. In improved and warmer weather it is still possible more plants may emerge. 2 more have recently been found at Annagh Lake, making 4 there. There are now 30 known specimens recorded on the north and east shores of Lough Allen. We have searched parts of the west shore, particularly Holly Island but none have been reported from all that side of the lake. (Updates will appear on our LOG2012, always available from the Home page.)

The fact that Spiranthes has returned to the south east corner but not the south west corner does suggest that the damage done at Holly Island and the wanton use of vehicles on that shore may be contributing to the elimination of this protected species in that area. Other sites on the west shore are now overgrown and do not seem sutiable for Spiranthes at present. That, and the absence of the species from the only site on the east shore that has changed in recent years (Kilgarriff) does emphasise this species susceptability to inadvertant land use change. We have sought to build relationships and discreetly make people aware of the rarity of this plant — and have received much sympathy towards nature among all we have talked to.

PLEASE CONTACT US IF YOU SEE THIS PLANT?

See 2012 Distribution Map below.

2011: Survey results shown below.

The Spiranthes Orchids are again flowering in good numbers in Lough Allen. The magnificient specimen on the Left was taken by Emma Dunne (from the Sligo Institute of Technology) who is on work placement this Summer with LoughAllenBasin.com

Photographs like these are one of our strongest tools in trying to protect the Environment from any unwanted development!

Unfortunately, this year all our records are coming from the north end of the Lake. Formerly large colonies, such as were found at Derrintober and Mountallen, have not flowered for the last 3 years! The possibility that the largish colony at Holly Island may have been destroyed by Vehicle traffic on the shoreline can be down-played by the fact that the other 2 clusters nearby have also failed to emerge, and they have been undisturbed over the past few years! Maybe they will emerge yet? (However, many thanks to the landowners in all 3 areas for generously allowing access to seek these plants.)

We would be very grateful if anyone finding these Orchids, particularly in the southern half of the lake, would inform us (086 3900731) or by eMail). Irish Lady’s Tresses are an exceedingly rare species protected by EU and Irish Law. The Flora Protection Act prevents them being picked or willfully damaged. It is species like this and the Curlews and Mergansers that make the Lough Allen environment unique and will guarantee its protection for future generations.

Many thanks,

Spiranthes romanzoffiana (Irish Lady’s Tresses)

Lough Allen’s extremely rare orchid has lost ground over the last 3 years and is showing a worrying trend to occur in fewer sites, thus becoming more exposed to risks. This plant is a major component of Lough Alllen’s powerful biodiversity — it would be a shame to lose it.

The maps below show the decline and the main locations where it has been seen in recent years. If you own this land we would, respectfully, ask you to look out for Irish Lady’s Tresses, and to look after them... The distribution so far recorded this year very much reflects the pattern recorded in the Map for 2010, with one extra colony found and a total of 45 plants so far; we expect many more!)

What to look out for!

There are 2 pure white flowered orchids that can be found around Lough Allen. One, the Lesser Butterfly Orchid is flowering now (June/July). The other, Irish Lady’s Tresses, is the rare one, and flowers in July/August.

Lesser Butterfly Orchid

From a distance, and superficially, they may appear alike. They both can appear as small white spikes half buried in grass or rushes. This one (on the Right) is the Butterfly Orchid and it occurs in sloping, often south facing, pastures well above the lake shore.

Irish Lady’s Tresses
RARE

These 2 photographs (Left) are of Spiranthes romanzoffiana — Irish Lady’s Tresses — restricted to lake shores (and so far, in this area, only Lough Alllen’s shore). It occurs within a narrow band between high and low water levels. If you see any of these orchids along the shoreline we would be very pleased to hear about them. Also, please do not pick them; they are a protected species!

They are just starting to flower now as we write! Please feel free to CONTACT US for more information or if you have sightings to give us. It’s important that the whole lake’s distribution be recorded so we can monitor any change in populations of this extraordinarily rare species.

Close-ups of the flowers of the 2 species.

The Spiranthes (Lady’s Tresses) is shown on the left. It often has a spiral flower and this characteristic of the species gives it its technical name — literally meaning ‘spiral flower’.

It is a very pearly white with a touch of green whereas the Lesser Butterfly Orchid flower (on Right) is yellower in colour. Also the structure of the latter is very open and does not show the twisted appearance of the Spiranthes. The long ‘spur’ typical of the Butterfly orchid can also be seen behind several of the individual flowers in the photograph on the right.

We, at LoughAllenBasin.com, believe that it is crucial that this regionally very unique habitat be allowed to continue to thrive. Many orchids are very well represented at Lough Allen but the Irish Lady’s Tresses is both quite unique, very beautiful, and possibly vulnerable.

How to save this rare plant?

1. Take care while walking along many shores of the lake. Look out for them as you go.

2. Will not be found in dense vegetation but happy on stoney, muddy, grassy shores but always very near the lake medial water level.

3. Grazing of the shoreline is no harm but excavation or boulder clearance on the shoreline may damage them.

4. Please inform someone if you come across one in an isolated spot. (Records are very useful.)

5. Do not pick them; they are a protected species.

6. It is good to allow genuine people come and see something rare and special; try to avoid squashing them though!

We are often amazed about how considerate people often can be! We (unlike the Spiranthes) are not natives of these parts. But it is home and we have come to appreciate the unique Flora and Fauna that Lough Allen has. It has become our pleasure, in our free time, to explore and record this Biodiversity.

This work should be valuable in years to come but it would not be possible without the support and kindness shown to us by people all around the Lake. If we ever, in moments of haste or panic, seem bothered or hurried... please forgive us and accept our appreciation for allowing us to study and record these unique gems!

The Spiranthes is only one of many Gems! We have a checklist of the Top Dozen Spectacular Species in our 2010 Brochure, which you can read HERE!

Viewing Irish Lady’s Tresses?

Finally... if any of you would be interested in seeing these rare Orchids, up until the middle of August, we would be happy to try and arrange this for you in association with the local Landowner. Some years they are spectacular; other years they may only barely survive. It depends a lot on the weather.
