Seasonal and multiannual dynamics of sedentary species populations of hunting interest

Abstract

The aim of the research was to study the number dynamics of the populations of dominant sedentary species of hunting interest as a theoretical context in arguing sustainable measures for the management of economic interest fauna. The studies between 2000-2021 shows that after a period of depression in the populations of sedentary species of hunting interest in 2004-2012 there is an increase from 2016-2017 till present of reproductive stocks in all studied species on average by 95%. The losses in the cold period of the year varied depending on the climatic conditions of the cold period of the year, as well as the age structure at the end of the reproductive period: for the hare between 14% and 30%, with an average of 23%; in grey partridge from 56% to 71% and in pheasant they fluctuate between 48% and 56% of the autumn number, being lower in warm winters (37%). Analyzing the dynamics of annual increases in sedentary small game species in different climatic conditions, it was found that arid conditions during nesting and offspring growth, decrease annual increases by 143% in pheasants, 122% in hares, and only 74% in partridges, which is a species less dependent on aridizations in the vegetative period.
