Analysis of the squirrel population dynamics dependence on the forage reserve (by the example of the Jewish autonomous region)

We have analyzed the forage reserve influence on the squirrel number change (by the example of the Jewish autonomous region). The approach, based on mathematical modeling, is used for the description of tendencies in the population size dynamics. The models verification is carried out and the present day condition of the squirrel population is estimated. It is shown that a change in the squirrel number is determined by the cedar nut yield in the years, prior to reproduction.
