Rock Wood is a 10.4-hectare (26-acre) biological Site of Special Scientific Interest north of Uckfield in East Sussex.[1][2]
This ancient wood has several different types of broadleaved woodland, a stream which cuts through a steep sided valley and a small waterfall. The valley has a moist and mild climate which provides a suitable habitat for mosses and liverworts which are uncommon in south-east England.[3]
