The projection:

"Alber's Equal Area Conic for Russia", 9, 1001, 7, 100, 0, 44, 68, 0, 0.

Basic contents:

The vector map of area consists of layer with polygons.

Maps were created on the base of generalized information about species distribution from published sourses (accuracy till regions).

The technique of drawing up of a map:

he area map was created on the base of literature data (Atlas, 1960; State list, 1994, 2004 etc.) and arable territory map for USSR (The Computer, 2003).
