Rare and remarkable species discovered in 2025

Written by Blue Kirkhope
A rare fungus named Cortinarius eucaeruleus was discovered at Killiecrankie.
We discovered seven rare and remarkable species across our special places in 2025.

As Scotland’s largest independent conservation charity and the nation’s largest conservation land manager among environmental charities, the Trust cares for a vast range of landscapes and habitats. From the deep seas surrounding Fair Isle and St Kilda to the montane expanses of Mar Lodge Estate, and from the machair of Iona to the dramatic slopes of Glencoe, our places are home to many of Scotland’s most vulnerable species.

Last year’s discoveries included fungi, flowering plants, lichens, insects and birds, many of which are found nowhere else in Scotland, the UK or, in some cases, the world. These finds reflect the Trust’s long-term investment in careful monitoring, habitat management and landscape-scale restoration amid the rapidly shifting climate pressures facing Scotland’s wildlife and the country’s changing natural landscape.

Highlight rare species discovered in 2025

Cortinarius eucaeruleus

This rare fungus, on the IUCN Red List of Threatened Species, was discovered by the Trust’s Seasonal Ranger Angus Todd and verified by mycologist Liz Holden. It displays striking bright violaceous blue caps and is associated with oak and hazel woodland and lime-rich soil habitat, which can be found at the Pass of Killiecrankie in Perthshire.

Small cow-wheat

This delicate, yellow-flowering plant of upland habitats is a priority species in the Trust’s Plan for Nature. A thriving population of small cow-wheat (Melampyrum sylvaticum) was recorded for the first time at Glencoe National Nature Reserve during a joint botanical expedition with the Trust and the Botanical Society of Britain and Ireland.

Corncrake chicks

When the Trust acquired the Treshnish Isles in 2023, the distinct rasping call of corncrakes could occasionally be heard, yet there was no evidence to confirm they were breeding there. However, this year unmistakable black fluffy corncrake chicks were spotted, which finally confirms that this endangered species is successfully breeding on the archipelago. Once widespread, corncrake numbers have declined significantly since the 1970s; they are now a Trust priority species.

Scotch annulet moth

The first record since 1979 of this scarce and modest upland moth on the Isle of Canna was made during the island’s new annual summer NatureFest activities. John Lorne Campbell’s impressive collection of moths and butterflies, amassed from the west coast of Scotland, has been preserved as a unique record of insect life and can be seen as part of the Canna House tours.

Thelocarpon actonii

A tiny yet phenomenal discovery, new to science, of a rare lichen was made by its namesake lichenologist Andy Acton at Glencoe NNR, representing an important addition to Scotland’s lichen diversity. Its characteristic violet fruiting bodies make this minute lichen unique.

Greater and lesser butterfly-orchids

A greater butterfly-orchid (Bannockburn) and nine lesser butterfly-orchids (Torridon) have been discovered flowering at two of the Trust’s places. This is the welcome result of reducing grass cutting at Bannockburn to restore wildflower meadows, and the reintroduction of nature-friendly cattle grazing in Torridon.

Mycetoporus piceolus

A nationally rare rove beetle with only 24 records across the UK, this species occurs under stones in montane habitat on slopes, ridges and summits – making Ben Lawers National Nature Reserve its perfect home.

These rare discoveries are not only indicators of the wealth of Scotland’s unique biodiversity but also demonstrate the importance of protecting them. They highlight the Trust’s uniquely broad conservation remit, which spans habitats, species, landscapes, geological features, cultural environments and historic gardens.

Jeff Waddell, Head of Nature Conservation for the National Trust for Scotland, said: ‘These discoveries are more than scientific records; they are reminders of what makes Scotland’s landscapes so extraordinary. From a rare fungus sprouting in ancient woodland to orchids thriving in restored grasslands, each find tells a story about the resilience of nature and the value of long-term conservation.’

“As custodians of some of Scotland’s most important natural places, we have a unique responsibility to look after the nature in our care, and we remain committed to restoring and protecting habitats where species can not only survive but thrive.”
Jeff Waddell
Head of Nature Conservation

Jeff continued: ‘These discoveries also remind us of the importance of safeguarding nature. Many of these species exist on the edge of their range or survive only in isolated pockets, and their presence in Scotland is a powerful signal that our conservation efforts are making a real difference. But it is also a reminder of the pressures facing these delicate ecosystems – from climate change to habitat loss – and the need for continued vigilance and support.

‘By restoring uplands, woodlands and grasslands and by monitoring these landscapes carefully, we’re helping ensure that these remarkable species and their habitats endure for generations to come.’

The Trust’s vital conservation work includes habitat restoration, species monitoring, ranger-led land management and public engagement. Through these efforts, our charity aims to safeguard the nature in our care while promoting and encouraging the access, education and enjoyment of nature.

Launched in 2024, the Trust’s Plan for Nature outlines our ambitions for conserving the nature in our care and will play an important part in delivering government commitments for nature, including the Scottish Biodiversity Strategy, and tackling the nature and climate crises.

The Plan for Nature supports the National Trust for Scotland’s vision to provide access and enjoyment of Scotland’s nature, beauty and heritage for everyone, as outlined in our 10-year strategy, launched in 2022.
