Asham Wood is the largest and most diverse of the ancient semi-natural woods in the Mendips. It has been the subject of controversy and attempts to protect the environment from increased quarrying activity in the area.
The wood occupies 2 deep valleys and the intervening plateau. Most of the underlying rocks are calcareous Carboniferous Limestone and Shales, but DevonianPortishead Beds outcrop along the northern valley. There are a range of unusual flora and fauna.
At Asham Wood near Frome coppicing and 50 dormouse boxes have been introduced in order to encourage nesting. The boxes are monitored and dormice numbers are recorded.
