Fen ragwort biology

Unlike other ragworts, fen ragwort is not an invasive species (2). It is a perennial plant (5) that can withstand flooding for up to six months (7).

Fen ragwort range

This species was once known from Cambridgeshire, Norfolk, Suffolk and Lincolnshire. It was first recorded in England in 1660 (6), and by 1857 it was believed to have become extinct in the UK, until in 1972 (6) a single plant was re-discovered in Cambridgeshire (5). It has since been reintroduced to five sites in its former range, including Wicken Fen National Nature Reserve (2) and Flag Fen in Peterborough (5).

You can view distribution information for this species at the National Biodiversity Network Gateway.

Fen ragwort conservation

Fen ragwort was one of the first plants to be included in English Nature's Species Recovery Programme (5). This programme is funding the conservation of the species in collaboration with Anglian Water. Measures that have been taken to help the species escape extinction in the UK include reintroductions to former sites, and research into the ecological requirements of the plant, carried out by the Institute of Terrestrial Ecology (2). A nursery has been established for rearing plantlets, grown from the seeds of the last remaining plant (5), and populations are carefully monitored (7). The fen ragwort is fully protected under the Wildlife and Countryside Act of 1981 (4).

There may be further information about this species available via the National Biodiversity Network Gateway.
