delineation, description, and analysis of relatively homogeneous units of land at the 

 local or regional scale. The concept of the ecosystems has been widely accepted as a 

 basis for organizing our knowledge offish and wildlife resources and for considering 

 their interaction with other resources. Although some commonality of ideas exists at 

 present, there is no uniform approach to ecological land classification. Cooperative 

 efforts are underway to develop common or compatible systems. As part of these 

 efforts, the problem of integrating wildlife data into the ecological land classification 

 process and of integrating land/ water ecosystem concepts must be resolved.
