Part of an extensive forest area, the site comprises partly drained stands of mixed and deciduous forest, with a significant proportion of oak Quercus and other hardwood trees. There are several small raised bogs, and two unregulated rivers and their streams run through the area.
The area is important for breeding Aquila pomarina.
