SUMMARY
The observed size of an animal population, as opposed to the genetic size, is given by the number of individuals in all categories as well as by the total number of males and females participating in the production of the descendant generation. The integration of Romaniainto the European Union requires special attention to the hunting populations. The purpose of the present paper was to study the evolution of the observed sizes of the hunting population for 13 species of animals in the period 2015-2019, on 17 hunting areas Nades, from TimisCountywith a total area of 9.325 ha. The present study highlighted that on this hunting area, Cervidae family – which includes ruminants with deciduous horns, is represented by 3 species, namely Red Deer (Cervus elaphus L), Fallow Deer (Dama dama L), and Roe Deer (Capreolus capreolus L). Also, it is concluded that it is permanently effective of European swan (Lepus europaeus P.), it is more important to choose the significant growth on this hunting area with 100% a Jackal (Canis aureus L.), at the beginning of 2018, compared to the year 2017. For the other identified species, the population of evolutionary numbers showed that there is a good correlation between the number of individuals and their biogenic capacity. The present study recommends the revival of the existing population on this hunting ground, through “blood refreshing” actions.
