County Wildlife Site

Visiting Long Deans in spring is like taking the first deep breath after a long winter. The open space in this valley invites you to meander and take in the scent of a new season. Early butterflies, such as orange-tip and brimstone and bees such as white-tailed queen bumblebees can be seen swirling around the wildflowers. Lift your gaze up and you might spot magnificent raptors, such as buzzard and red kites wheeling and displaying on the thermals created by the early warmth of the spring sunshine. The flower-rich grassland is scattered with impressive veteran trees which provide a home for fungi, invertebrates, birds and bats. 

Wildlife to spot
Discover birds of prey, including kestrels, buzzards and red kites all year round, butterflies in spring and summer and beautiful orchids, such as the mimicking bee orchid and pyramidal orchid in summer. In winter, you might find visiting redwings feasting on berry-laden trees.
