Black and brown bear density estimates using modified capture-recapture techniques in Alaska. Stanford University Press, Palo Alto, California. Where multiple numbers are within a subpopulation (dotted polygon), estimates are for separate jurisdictions delineated by a light solid line (i.e., provincial, international boundaries, or the limit of a survey effort). (2007), Environment Canada (2009), and ASRDACA (2010), although most of these depict coarse-scale “best guess” demarcations on maps based on sightings, mortality events, and/or perceived habitats with little to no confirmation of occupancy of these habitats over time. August 2010. Their fur color ranges from black to light brown, making color a poor method of identification. Aversive conditioning programs have been implemented in many places to take advantage of bears’ ability to modify their behaviours (e.g., review in Schirokauer and Boyd 1998), and have been successful in some instances (Honeyman 2008). and Alberta, where habitat fragmentation and degradation through expanding human settlement, resource extraction, and recreation is ongoing and intensifying in some areas (Proctor et al. Modeling the spatial distribution of human-caused grizzly bear mortalities in the Central Rockies ecosystem of Canada. The best identifier for a grizzly bear is the large hump on their shoulders that is best seen while they are walking. (2003b) observed major shifts in litter production occurring at 4–5 years of age (age at first reproduction) and at 28–29 years (senescence), with a litter every 3 years between those ages.

Suspected percent reduction in total number of mature individuals over any 10 years or 3 generation period, including both the past and the future. Female movement rates peak during summer when, in this area, food availability is low. Members of the Willow Lake Métis Local 780, based in Anzac, Alberta, indicated in summer 2009 that they had seen Grizzly Bears around the Connacher Great Divide SAGD Expansion Project area that were not there previously (Connacher Oil and Gas 2010). Craighead, J.J., J.S. 1994. Bear in human imagination and ritual. comm., 2011). Though largely investigated with respect to impacts of climate change on Polar Bears, a few authors have considered the results of increasing range overlap between Polar Bears and Grizzly Bears, including hybridization and competitive exclusion. Canadian Journal of Zoology 41:33-45. U.S. Important, given importance of salmon in particular to coastal populations. The majority of Grizzly Bear habitat in Canada is publicly owned. North American Aboriginal perspectives on Grizzly Bears and bear-human relationships are surveyed broadly in the monographs of Hallowell (1926), Rockwell (1991), and Shepard and Sanders (1985), and the dissertation of Clark (2007).

However, this observation may also be due to reduced propensities for bears to cross busy corridors (Gibeau et al. Boyce, D.R. Approximate boundaries of the current and historic (i.e., 19, Figure 3. Hanley. Seip. 9:89. Age variation in gross and histological characteristics of the testis and epididymis in grizzly bears. 1990. These areas represent about 7.1% of the area of occupancy in Canada. Effects of transportation infrastructure on grizzly bears in Northwestern Montana. Countries such as Russia support sizable populations of Brown Bears; however, many populations in Europe are insular, small, and endangered. October 2010. Canadian Journal of Zoology. Fish and Wildlife Service (USFWS). Recently, efforts to model areas of relatively high security for Grizzly Bears (areas where bears can meet their energetic needs while avoiding human-caused mortality) have informed conservation-based land-use planning initiatives, including identification of habitat linkage zones (e.g., Gibeau et al. This report may be cited as follows: COSEWIC. ), dominate the species’ summer diet in the Flathead, and during late summer berries comprise up to 96% of scat volume. J.A. August 2010. 1976. In addition, the population of Grizzly Bears that once occupied northern Quebec and Labrador is now assessed as a DU, the ‘Ungava’ population.

Ciarniello, L.M., M.S. 2012). 2009. Relationships between human industrial activity and grizzly bears. In that area, Grizzly Bears killed four times more animal biomass than they scavenged. (1) estimated annual survival rates are based on averages extracted from the columns in Table 2, and are therefore considered constant across the age-brackets shown on that table, (2) age of first reproduction is set at 6 or 7 years of age (6.7 being the average derived from summary data in Table 1, Ferguson and McLoughin 2000), and (3) survival and triennial reproductive frequency is held constant until animals reach 25-30 years of age (i.e. The following sections describe in detail the most important limiting factors and threats to Grizzly Bears. Age at first reproduction varies substantially across the range of the Grizzly Bear. The Grizzly Bear can also be an important part of subsistence hunting by some Aboriginal people for both food and cultural purposes. Festa-Bianchet, M., M. Urquhart, and K.G. Of greater concern to Grizzly Bear status and conservation are those activities that result in functional habitat loss. Apps, C.D., B.N. Zoologische Garten 1876:20-22. August 2010. 2008.

In Wapusk National Park, Manitoba, seven of nine known encounters have occurred since 2003 (Rockwell et al. *** Formerly described as “Indeterminate” from 1994 to 1999 or “ISIBD” (insufficient scientific information on which to base a designation) prior to 1994. Historical numbers in Canada are unknown, but were certainly much higher. Alberta Tourism, Parks and Recreation, 2nd Floor, Oxbridge Place, 9820 - 106 Street, Edmonton, AB T5K 2J6. 1987). P.I. 2012; see Population Structure and Variability), making it highly likely that interchange occurred between the Grizzly Bears of the Prairie and at least bears inhabiting the Rocky Mountains of Alberta. The Grizzly Bear (Ursus arctos) is believed to have crossed over from Asia to North America 50,000 – 100,000 years ago. 2009). Forestry, Lands and Wildlife, Fish and Wildlife Division, Edmonton. 2001), but consume relatively large amounts of vegetation. Christensen, Michelle. Human activities influence how bears use potential habitat; zones of human activity are generally avoided or characterized by high human-caused mortality (McLellan and Shackleton 1988; McLellan 1990). Whether bears existed south of the last continental ice sheet has been the subject of debate. 1965. As with many polygynous species, more male Grizzly Bears can usually be hunted than females without leading to overall population decline (Caughley and Sinclair 1994). Trichinosis from frozen grizzly bear meat. Bear experts blame drive-by poaching for the illegal killing of grizzlies in Alberta. Most agencies attempt to account for unreported mortalities in their Grizzly Bear management plans, but documentation, especially for illegal kills, is difficult. As for the possibility of subdividing the Western DU, there is no natural disjunction between substantial portions of the unit’s geographic range in Canada. vii + 91 pp. The American black bear is the most commonly seen bear in North America, and it has the largest geographic range. Final Report. Predation on moose and caribou by radio-collared grizzly bears in east central Alaska. 1999; Mowat & Heard 2006). As detailed throughout this report, geographic variation in body size, life history parameters, and food habits are evident across certain parts of Grizzly Bear range. This historical evidence implies that the geographical partitioning of mtDNA haplotypes, which reflects only female-mediated gene flow, is relatively recent. They'd probably take over quite fast." Woods, D.W. Carney, M.L. Denning ecology of barren-ground grizzly bears in the central Arctic. Salmon and ungulates are particularly important dietary components. Appendix 7 (PDF; 1.15 MB) – Traditional Land Use. Banff National Park: science and policy in grizzly bear management. Wildlife experts say the death of a mother grizzly bear and her two cubs — including a rare, blond-headed grizzly — in Banff National Park is a major loss to the population. In central and northern British Columbia, some Métis Traditional Knowledge (MTK) holders in that province feel that populations have generally increased in their traditional areas over the past few decades (Ducommun 2010). Rates of capture-related deaths are variable, but can be reduced to very low levels with experience of handlers (e.g., <0.1% of handling incidents in BC; B. McLellan, Government of BC, pers. Human-caused mortality is a major contributor to overall mortality in most areas where Grizzly Bears occur, and is related to sex and age. They can be found from sea level to high-elevation alpine environments. Otherwise, populations in the lower 48 United States are generally small and fragmented (estimated to number in total approximately 1,200–1,400 bears; USFWS 2011). 2000. 1987. Rationalization for this DU was based on the loss of the species from the unique Prairie ecozone in the late 1800s, yet the Prairie Grizzly Bear was undoubtedly continuous in range with the current Western population. The American Midland Naturalist 79:247-250. Herrero, S., J. Roulet, and M.L. 118pp. Ursus 10:41-47. Canadian Journal of Zoology 77:1623-1630. This animal is not plentiful, although common enough and too common to suit some of the natives who have a wholesome dread of it. Estimating abundance of Grizzly Bears is costly, difficult, and generally imprecise, particularly in large and remote areas, which characterize much of the distribution. Four mitochondrial DNA clades were proposed through this work. 2, Toronto, Ontario, Canada. Colour ranges from blonde through shades of brown to nearly black, with the sometimes silver-tipped nature of the fur giving the species a ‘grizzled’ appearance. Mattson, D.J., M.G. Department of Environment, Iqaluit, NU. Wildlife Inventory Section, Resources Inventory Branch, Ministry of Environment, Lands and Parks, P.O. Although the loss of Grizzly Bears from the Prairie ecozone has resulted in an extensive gap in Grizzly Bear range in Canada, this gap is no different from other areas outside the ecozone from which they have disappeared.
