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).
