Rare orchid found in Scotland

Rare orchid found off Scotland's west coast 

November 2013: An extremely rare orchid growing on an island off the west coast of Scotland has been discovered by RSPB Scotland volunteers, where it has never before been recorded.Irish lady’s-tresses, named for its resemblance to plaited hair, is thought to grow at very few sites in the UK and Ireland, meaning the discovery of around 160 plants on Oronsay is a significant find.

Due to its rarity, the reproductive habits of Irish lady’s-tresses aren’t well known, but in this case, they have probably been lying dormant underground for many years just waiting for the right conditions in which to flower.

Volunteer Gill Watts, who found the orchids with her husband Richard, said: “We were actually surveying for marsh fritillary butterflies when we spotted all these white flowering spikes coming out of the ground. We thought at first they might be a more common orchid, but after checking with the RSPB reserve manager, we managed to positively identify them.“They’re amazingly beautiful flowers, with a musky vanilla fragrance. We didn't quite believe what we’d found at first, because we know they’re so rare. And to top it all, we learned that it had been our privilege to make the first ever record of this plant for Oronsay!”

Oronsay, a tidal island just off Colonsay, is an RSPB Scotland nature reserve that is actively farmed to create homes for nature, particularly choughs and corncrakes. Its seal colony was featured on the BBC programme, Hebrides: Life on the Edge.The management of the particular field where the orchids were discovered, was altered a number of years ago to provide good conditions for devil’s-bit scabious. This is the food plant of marsh fritillary butterfly caterpillars, another species suffering steep declines in the UK.

The butterflies have now been breeding on Oronsay for several years and their range has expanded across the island. Meanwhile, the good conditions for devil’s-bit scabious have also proved just right for Irish lady’s-tresses. 

Deborah Long from Plantlife, said: “2013 has been an exceptional year for orchids. And what is more exceptional than a new site for the very rare Irish lady’s-tresses orchid? Plantlife have been working on this species for over 10 years and with new research indicating the extreme fragility of its populations in Scotland, to find a new population on an RSPB reserve inspires hope for the future of the species. Given appropriate management, it just shows that Irish lady’s-tresses orchids can come back to their homeland.”

Devastating fire uncovers rare native orchid


A fire that ravaged 70 hectares of peat-filled wetlands near Rangiriri killed several birds and animal but also uncovered a threatened native plant.
Conservation Department staff found the green-hooded swamp orchid in the burnt remains and Waikato biodiversity programme manager John Gumbley hopes others might flourish after the fire.
However, while some native plants flourished in such habitat, the fire had proved devastating for several birds and animals, the remains of which were found by staff as they examined the scene yesterday.
"The area burnt contains important threatened plant communities and species, notable wire rush and priority threatened native orchids such as green-hooded swamp orchids ... the site would have provided habitat for threatened or at-risk bird species such as banded rail."
Mr Gumbley said DOC staff would continue to monitor the site, not only for signs of fire, but also to see if other threatened species emerged.
"Some threatened plant species such as orchids emerge if the fire has not been deep-seated and destroyed the seedbank in the peat. But uncontrolled fires such as these are very damaging to natural ecosystems, especially peat bogs, with the possibility that some flora and fauna do not survive or recover locally."
The orchids' re-emergence comes about as they are low-lying plants and their seeds can re-emerge without competition from taller plants.
But the concern was around wetlands. Waikato had lost 90 per cent of its wetlands, so human-induced fires could be devastating, he said.
DOC carried out controlled burns in peat wetlands near Meremere to enable the threatened native orchid to survive or emerge, Mr Gumbley said.
Meanwhile, Taumarunui firefighters battled a 5000-square-metre fire for four hours in a pine plantation at Waimiha about 8.50pm Tuesday.
A helicopter was turned out but sent back due to bad weather.
It returned to douse the blaze early yesterday.
