| Summary: | The detailed analysis of long-term account data for the main hunting mammal animals is carried out. The population size dynamics of the following hunting animal species is analyzed: herbivores Ussurian moose, Manchurian deer, Manchurian roe Ussurian wild boar predatorsUssurian brown bear, Siberian forest wolf, Ussurian fox, Siberian river otter, Siberian sable, Manchurian weasel rodents and hares – Sakhalin-Amur squirrel, Amur blue hare, Manchurian hare. The approach based on mathematical modeling is used for the description of tendencies in the population size dynamics. General mathematical model of the population dynamics of harvest species has been developed. It reflects a periodicity of the reproduction process and focused on the description and research of demography population dynamics and the hunting influence results. Model parameters are estimated on the basis of the harvest statistics and account data for the hunting mammal animals. Modeling retrospective forecasts made it possible to show adequacy of the model to the majority of game species. It is shown, that maintenance of the population size and age structure for many game species is determined by their migration activity. Reserved territories promote preservation of hunting species and determine even some growth in their population size, but it is obviously insufficient. It is necessary to expand the territories free from harvesting and transfer to the strategy of rigid restrictions of hunting for the populations with depressive regime in the dynamics. |
