Use of Pen-Reared Black Bears for Augmentation or Reintroductions
Because bears readily breed in captivity, the use of progeny of penned animals as a source for augmentation and reintroduction has been suggested. We radiotagged 6 pen-reared black bears (Ursus americanus; 4 male, 2 female) that were released in the wild between 2 February 1988 and 24 May 1988. We also collected release and recovery […]
Automatic Monitoring System for Brown Bear in Trentino, Italy
In this century, the brown bear (Ursus arctos) population in the Alps has declined; a few individuals survive in the Adamello-Brenta Natural Park in Trentino, Italy. This population is at high risk because it lives in one of the most highly populated and rapidly changing bear ranges in the world. Management of the bear and […]
Management of Bear-Human Conflicts Using Laika Dogs
Conflicts between brown bears (Ursus arctos) and humans have occurred since both species first occupied habitats concurrently. Although the nature of bear-human conflicts has remained similar, methods for resolving them have improved with technological advances, to the extent that humans and bears now have a better chance of coexistence. Conflict-resolution techniques used in the United […]
Reproductive Rates of Brown Bears in the Cantabrian Mountains, Spain
We studied brown bear (Ursus arctos) reproductive rates by monitoring females with cubs in the 2 unconnected populations in the Cantabrian Mountains in northwest Spain. Annual average number of females with cubs, number of cubs, and litter size were 5.00, 11.20, and 2.24 respectively, for the western population (1986-90), and 1.67, 2.67, and 1.67, respectively, […]
Biogeography, Demography and Management of Ursus arctos in the Western Carpathians
During the 1930s the brown bear (Ursus arctos) population in the western Carpathians was endangered and numbered 0.6 bears/ 10 km2. In addition 2,500 km2 supports
Brown Bear Density Based on Observations by Moose Hunters
Moose (Alces alces) hunters were asked to report brown bear (Ursus arctos) observations made during the hunting season in central south Norway and in the eastern part of Hedmark county in the late 1960s and 1970s. Extremely high values for hunter-days/bear observation were obtained, indicating very low bear density. The density in Hedmark was about […]
Survival and Reproduction of Translocated Virginia Black Bears
Since 1987, the Virginia Department of Game and Inland Fisheries has translocated 221 nuisance black bears (Ursus americanus) from the periphery of Shenandoah National Park in northwestern Virginia to southwestern Virginia in an attempt to reestablish a viable bear population in southwestern Virginia. Forty-three bears released in 1990 and 1991 were radiocollared and monitored from […]
Brown Bear Predation on Domestic Sheep Registered with Mortality Transmitters
During 1989, 291 lambs in 3 herds of domestic sheep were tagged with silent mortality transmitters prior to release onto open, coniferous forest range in southeast Norway. Twenty-six lamb carcasses were recovered. Lamb mortality was attributed to disease (19%), accidents (22%), and predation (59%). In addition to the dead lambs, the carcasses of 21 ewes […]
Damages Attributed to the Brown Bear in Spain: The Case of Asturias
An annual average of 77 claims for damages allegedly caused by brown bears (Ursus arctos) totaling 7,159,229 pesetas ($71,592 US) were reported in the 2 year period of 1989-90 in Spain. Of these claims, 97% were from the Cantabrian Mountains and 3% were from the Pyrenees, reflecting the different sizes of the 2 bear populations. […]
First Experiences with the Release of 2 Female Brown Bears in the Alps of Eastern Austria
In June 1989 and June 1992, 2 female brown bears (Ursus arctos), 3.5 (bear 1) and 6.5 (bear 2) years old, respectively, were released in the Limestone Alps of Styria and Lower Austria. The release area was within the home range of an old male that had migrated from Slovenia in 1972. Ranges used in […]
