Natural resources within Chester County have been mapped and inventoried by a number of county, state, and federal organizations. Most of these maps are compiled at the regional level. Thus they are useful for preliminary investigations, but do not provide the sort of detailed inventory needed to rigorously evaluate conditions on an individual property.
