“…The resulting density of 120 red deer per 1000 ha of forest area was 3 to 4 times as high as the highest recorded density in Poland (Pielowski et al 1993) and, as far as we know, in continental Europe for that matter. And so, it was 2-3 times higher than that in Belgium (Bertouille and de Crombrugghe 1995) and close to average density of red deer in Scottish hill-land (Mitchell andCrisp 1981, Ratcliffe 1984).…”

“…Condition of each individual had been assessed with the aid of three indices: body weight, kidney fat, and visceral fat. The body weight is easily available and depicts well any changes in physical condition (Dzi^ciolowski 1970, Buchli 1979, Albon et al 1983, Bertouille and de Crombrugghe 1995. Other broadly used indexes are fat reserves, especially kidney fat (Franzmann 1992, Shea et al 1992.…”

. 1996. Physical condition of red deer in a high density population. Acta Theriologica 41: 93-105.Physical condition in a living at high density (120 individuals/1000 ha of forest area) red deer Cervus elaphus Linnaeus, 1758 population was studied by determining: dressed body weight, kidney fat index (KFI) and amount of visceral fat in 628 animals. Antler weights were also considered as condition index of stags. The mean body weight of calves of both sexes was identical, ie 38.0 kg, that of hinds fluctuated from 57.8 to 75.1 kg, stags -from 63.2 to 132.4 kg depending upon age. The KFI value for female and male calves, hinds, and stags at various age amounted respectively to: 1.54, 1.36, 1.60-1.76, and 1.17-2.69. Per cent of individuals with great amount of visceral fat amounted: in female calves -to 39.4, in male calves -33.3, in hinds -47.6-66.7, and in stags -20.0-100.0% depending upon age. Maximum weight of antlers was 4.2 kg. Despite high population density animals indicated generally good physical condition. Except that the condition of calves of both sexes has been maintained at a similar level, what evidenced an inferior condition of males during their growth. Males in contrast to females, reveal serious decline of condition following the rut, during autumn and winter. It was related to stag age and most marked in the animals of the oldest age-classes (no less than by 40%). Factors affecting the condition of red deer in their population from the Słowiński National Park were discussed.

“…Population density (Klein et al 1987, Hewison et al 1996, Ashley et al 1998, climatic conditions (Gaillard et al 1996, Post et al 1997, and habitat quality (Bertouille andDe Crombrugghe 1995, Hewison et al 1996) are factors involved in short-term changes of body size and condition of deer within a population. Results from several studies on leg length of reindeer and caribou, reviewed by Klein et al (1987), noted that skeletal development depended primarily on nutritional conditions experienced by animals, which depended on both population density and climatic regimes.…”

Wildlife managers frequently use estimates of population densities to guide ungulate management. Because it is nearly impossible to obtain accurate counts, these estimates are based on indices. Thus, managers continue to seek new index methods that could help them better monitor and manage ungulate populations. In this paper we examine the usefulness of hind foot length as an ecological indicator of density dependence for monitoring roe deer (Capreolus capreolus) populations. We used the hind feet of all roe deer shot over an entire province for 13 years that were collected by wildlife managers from the Tarn Hunter Federation (France) to conduct this research. Information on the sex, date, and shooting locality were recorded by hunters, and animal age was determined by wildlife managers. We divided the province into 3 biogeographical regions and investigated the relationship between hind foot length of roe deer fawns, spring and summer climate (temperature and precipitation), and an index of deer density (number of shot roe deer per square kilometer) by region using linear models. Hind foot length differed between sexes and between regions. In 2 out of 3 regions, we observed a negative relationship between hind foot length and our index of roe deer density. Further, hind foot length was lower when springs (but not summers) were cold or wet. We interpreted these trends in relation to changes in population density and habitat structure. We concluded that hind foot length is a useful indicator for assessing the density‐dependent relationship between roe deer populations and their environment and for monitoring population trends.
