Succisa pratensis
Ecology
A perennial herb, growing in a wide range of moist to moderately free-draining habitats, and favouring mildly acidic soils. It occurs in woodland rides, in heathland and grassland and in mires, and in the uplands on cliff ledges and in ravines. 0-970 m (Carnedd Dafydd, Caerns.).
Status
Trends
S. pratensis was mapped as `all records` in the 1962 Atlas. A widespread decline in S. and E. England has taken place, and analysis of the database reveals that most losses have occurred since 1950. These losses are largely attributable to the improvement of grassland and heaths.
