The limestone grassland of this Reserve provides a rich array of wildflowers including birds-foot trefoil, kidney vetch and horseshoe vetch. These are good for butterflies and for other insects such as the Grey Bush-cricket. The sheltering copse of sycamore and ash trees and the scrub-covered slopes down to the disused railway track provide roosting places for insects and shelter for birds, particularly tired migrants arriving on Portland. The sheltered tall grass is one of the best sites on the island for glow worms.
Leased as a butterfly reserve since 1998, and part of the Bottom Coombe Site of Nature Conservation Interest (SNCI) complex. Management is carried out to stop the scrub encroaching onto the grassland, particularly non-native plants like Cotoneaster horizontalis which poses a serious problem.
There may be guided walks and conservation work you can join on this reserve: see our Events page.
