Habitat, density and spatial structure of the forest roe deer population

Demographic processes in a forest roe deer population

“…In both cases shooting was below average level (Table 3) and could not have been a significant cause of the drop in population density. The relation between density of the roe deer population at Zielonka and weather conditions and shooting has been analyzed in greater detail by Fruziński et al, (1983). The results of the study fully confirmed the known, although not documented under Polish conditions, high productivity of roe deer populations.…”

“…migration, has not been taken into account in this discussion. Observations of marked individuals permit of stating, however, that it is the young individuals which are involved in migrations, the spatial range of which is limited (Fruziński et al, 1983), and thus in an extensive forest area they take place within the population's living area, not significantly affecting its numbers. There have as yet been no data on the emigration of marked individuals beyond the area of the wooded land studied.…”

“…The species composition of the tree stands and quality of biotopes represent the average type of forest hunting range in the Wielkopolska region in the western part of Poland. A detailed description of tree stands and biotopes has been given by Fruziński et al, 1983. In order to obtain the most accurate data possible, part of the range (Potasze forest district) about 700 ha in extent was chosen, on which studies were concentrated over the period [1975][1976][1977][1978][1979][1980]. The character of the tree stands and density of the roe deer population were similar there to other parts of the Centre, but the area was partly isolated from the remainder of the wooded land.…”

Grouping tendencies in roe deer under agrocenosis conditions

“…These animals live in decidedly larger groups in open territory. Roe deer in treestands lead a mainly lone or family way of life through the whole year, and the size of the groups they form does not exceed 10 individuals (Kurt, 1968;Pielowski, 1970;Dzięciołowski, 1979;Fruziński et al, 1983; and others). Groups of roe deer in fields during the autumn-winter period, however, consist of several, or approximately 10-20 individuals, or even over 100 (Schechtel, 1929;Meisnerowski, 1959;Pielowski, 1970;Bresiński, 1975;Graczyk & Bereszyński, 1978;Zejda, 1978).…”

Population characteristics of roe deer inhabiting a small forest

“…There are, however, grounds lor suspecting that at least in larger stretches of such wooded land roe deer may live which cannot be fully identified with field roe deer. The correctness of such a hyphothesis is borne out at least by the fact that the size of forest roe deer's home ranges does not exceed 50-70 ha and with considerable density in wooded areas covers a far smaller area (Hennig, 1962;Mottl, 1962;Prior, 1968;Kurt, 1968;Strandgaard, 1972;Fruziński et al, 1983;Pielowski, 1983 and others).…”
