Cervides population dynamic in Šešuolių forest in Ukmergė distict is rewied in diploma paper. Moose (Alces alces), Red Deer (Cervus elaphus), and Roe Deer (Capreolus capreolus) were cowered by this investigation.. They are important as hunting species. For this purpose I have made survey of these ungulates in Šešuoliai forest. Surveys were continued four years from 2004 till 2008. Results were compared between years to find changes in abundance. It was found that the density of population in 2007 – 2008 was 46 individuals of Roe Deer, 11 individuals of Red Deer, 7 individuals of Moose; in 2006 – 2007 years the density of population was 42 individuals of Roe Deer, 11 individuals of Red Deer, 6 individuals of Moose; in 2006 – 2005 was was 53 individuals of Roe Deer, 14 individuals of Red Deer, 10 individuals of Moose ; in 2005 – 2004 was was 58 individuals of Roe Deer, 14 individuals of Red Deer, 8 individuals of Moose. Average density of Moose was 2,9 ±0,3 ind. /1000ha, that of Red Deer 4,8 ± 0,3 ind./1000ha, and Roe Deer - 19,1 ±1,3ind/ 1000ha. Obviously that the status of investigated species was not stable. In comparison the last two years population of Moose decreased, the density of Red Deer did not change, but the density of Roe Deer increased. Number of cervids is decreasing because of constant hunting and poaching. Modelling of the population allows to assess and control of the influence of various factors, which change number of individuals in real populations. It is also recommended, that survey numbers should be checked out, computerized and made available for free use. Insufficiencies of survey should be corrected by better survey methods. |
