HISTORY:
     The manuscripts were drawn during 1976 by the various  wildlife 
managers (game wardens) of the Arizona Game and Fish Department.  The 
scale of the manuscript maps was one half inch to one mile (1:126,720)
 and the base maps were the 'County General' series provided by the
 Arizona Department of Transportation.
     The map attributes represent Arizona's natural vegetation as 
delineated in the 'Journal of the Arizona Academy of Science', Volume 9,
supplement 2, Appendix F, published May 1974 using a classification scheme
developed by David E. Brown and Charles H. Lowe.  The University of Arizona
did the digitizing of the gfveg manuscript during 1992 and 1993.
 
Note: This is a different classification than the one appearing on Brown
and Lowe's, 'Natural Vegetation of the Southwest' which is the cover NATVEG.
