Yellow marsh saxifrage is a tufted, hairy plant, with stems of a reddish-brown. The leaves are spear-shaped and concentrated around the lower half of the stem. The flowers are bright yellow, sometimes showing small red spots.
Found throughout much of Europe, the yellow marsh saxifrage is threatened across much of its range. Once found in 13 counties in Britain, it is now restricted to some 20 sites, most of them in the north Pennine region of England.
The yellow marsh saxifrage is listed in the UK Biodiversity Action Plans (UKBAPs), and is included in English Nature's Species Recovery Programme (SRP). Recent surveys of this plant have suggested that known populations may have been under estimated through the grazing off of flowers heads. This makes it hard to recognise the plant in the field.
It is realised, however, that upland over-grazing has to be controlled if this species is to have a future in the UK and, as a precautionary measure, seeds have been collected and stored in the Millennium Seed Bank by the Royal Botanic Gardens, Kew. Some of these seeds will be propagated and planted back in the wild on suitable sites as part of a re-introduction programme.
As the yellow marsh saxifrage is threatened throughout its range, an important aspect of the work to conserve it has been co-operation with European conservation groups, to find out more about its biology.
The UK Biodiversity Action Plan for this species is available at UK BAP.
