Abstract:

Researches on wolf population from the South side of Făgăraş Mountains – Argeş County were done from 1996 till 2006, in order to establish its state parameters (individual numbers, density of individuals, age structure, sex ratio) and also its state variables (natality and mortality). The dynamic of individual numbers from 1996, the first year of researches, till 2006, the last year of researches, was as follows: Voievoda: 2-2; Şeţu: 1-1; Portăreasa: 2-3; Huluba: 0-2; Frăcea: 2-2; Dobreiaşu: 0-2; Leaota: 2-3; Făgeţel: 2-4; Valea lui Coman: 2-3. There were a total number of 13 individuals in 1996 and 22 in 2006. In some areas, an increasing number of individuals was realised between 1996 and 2006: Portăreasa = 1; Huluba = 2; Dobreiaşu = 2; Leaota =1; Făgeţel = 2; Valea lui Coman = 1; there were no increase, no decrease in numbers in the remaining areas. As an average, in all areas, rate of mortality was 0.35%, and this figure was mainly because of endogene factors. As age structure is taking into account, only one area (Valea lui Coman), had pyramid base, represented by juveniles, numerically higher than that of adults, which means, theoretically, that respective subpopulation was most viable than other all wolf subpopulations.

Keywords:
