About the reserve

Thorley Wash was designated as a Site of Special Scientific Interest in 1986 for its botanical interest associated with tall wash grassland habitat. Wildflowers present include ragged-robin, marsh marigold, fen bedstraw and meadowsweet. Water voles are flourishing here thanks to a successful reintroduction programme by the Trust in 2015. The wet habitats are great for a diverse range of wildlife including dragonflies, damselflies, birds and bats. Areas of long vegetation provide shelter for small mammals and reptiles.

Seasonal Highlights
Spring:
 Cuckoo, ragged robin, water vole, whitethroat.
Summer: Banded demoiselle, garden warbler, sedge warbler.
