The only area of established woodland within the Park, is Winchfield Wood, located in the southern area of the Park. 

It is thought that this woodland could be ancient woodland.  This means that there have always been trees on this site since 1600.  Ancient woodland is thought to be of great benefit to wildlife as ancient woodland contain plants which take a long time to establish and are not found in younger woodland. 

It is possible to guess whether a woodland is ancient or not based upon the plants found in the woodland.  Two plants which usually indicate that the woodland is ancient are bluebells and dogs mercury, both of which are found in Winchfield Wood.
