Description:

Potential Natural Vegetation for Region 8

Abstract:

   "Potential natural vegetation is defined as the vegetation that would        
    exist today if humans were removed from  the scene and if the plant         
    succession after their removal were telescoped into a single moment.        
    The time compression eliminates the effects of future climatic              
    fluctuations, while the effects of human's earlier activities are           
    permitted to stand. The potential natural vegetation is a particularly      
    important object of research because it reveals the biological potential of 
    all sites" (p. 89)                                                          
    This coverage was developed by the Florida State University Department      
    of geography in 1975 and is based on A.W. Kuchler's map of 1966.

Purpose:

    This coverage is suitable for use in Arc/Info and related software.         
                                                                                
   Intended use of data:                                                    
    Mapping of potential natural vegetation.

Supplemental_Information:

Limitations_of_Data:

   This coverage is not for delineating actual vegetation.

Procedures:

   This coverage was created by the FSU Dept. of Geography by digitizing        
   from A.W. Kuchler's Potential Natural Vegetation map of 1966.

Reviews_Applied:

    None.

Overview_Description:

Entity_and_Attribute_Overview:

    The code indicated as VEG in the item descriptions is a link to the         
    VEG.DAT look-up table. This data listing describes the codes with          
    both a common and latin name. "In general, the names of shrubs and          
    forbs adopted herin are those used by scientists considered most            
    authoritative on the vegetation of their respective regions. Taxonomic      
    plant names, however, may change sometimes, and authors may disagree on     
    which names should be used, but that problem can usually be solved by       
    consulting the following source material:                                   
       _Check List of Native and Naturalized Trees of the United States_,       
         Elbert L. Little Jr.                                                   
       _Manual of the Grasses of the United States_, A.S. Hitchcock and         
         Agnes Chase" (p. 89)
