This is something that has bugged me about Mapnik and Osmarender as well.  I
think you should start a wiki page about this issue.

The thing about the several renderers we currently have is that they can't
be expected to take every possible mapped feature into account.  The map
would just get too cluttered.  I think for a general street map (the Mapnik
layer)  one color for all types of protected/conservation designated land is
fine.  Borders between different land designations should be shown as well.
 It seems to me that national/state parks are often surrounded by
national/state forest, but the opposite is not often true.  Probably parks
should be rendered above forests, or better yet render them with
transparency above forests so the borders of both can be seen.  Of course I
don't know who is in charge of the renderers so I can't really change the
way it's currently done.

I think eventually another layer should  be created that show the
distinctions between BLM, USFS, NPS State Parks, etc....   In preparation
for that we should definitely have a wiki page detailing how to tag these
public land types.
