All the wildlife management areas in West Virginia were apparently 
sourced from the USGS PAD-US database. [1] That national-level database 
is aggregated from local sources, analogous to how TIGER and NAD are 
compiled. Given the discussion on [1], I don't think we can be sure that 
the imported WMA data lines up with the actual data in PAD-US. Some of 
the WMA boundaries have been manually corrected based on imagery 
overlays, but seemingly not all. [2] So definitely don't conflate the 
WVDOF data to the existing WMA boundaries until we're sure about that.
