Acker, M.J. 2018. (2018) predicted that the amount of suitable habitat for marmots on Vancouver Island will decrease as a function of climate change. This rate included the recruitment of captive-released marmots into the wild population, so the rate of decline based on reproduction and survival of marmots in the wild population was even higher. They are categorized scientifically under the biological name (Marmota vancouverensis) and are regarded as the largest members of the squirrel family. Nielsen, and M.M. Ethology Ecology and Evolution 21:209 to 223. Jackson, C. 2014. B.C. Malcolm McAdie, personal communication, Sept. 2016. The size and number of families varies between colonies and years, often producing dramatic fluctuations in population size in a given location. Senior Biologist, TimberWest, Nanaimo, British Columbia. It is unlikely that the two species would hybridize even if in the same habitat. In this case, human activity creates a refuge from predation. However, the subalpine habitat in which marmots live is often remote and inaccessible to people, thus, there is always a chance of finding additional mountains occupied by a few marmots. The negative impact will be minimized for some marmots because they live in areas where there is a spectrum of habitat available and they may move to more favorable habitat. Deer and Elk Habitats in Coastal Forests of Southern British Columbia. 1991), perhaps as a numerical response to deer populations (Bunnell 1990, Bryant and Page 2005). Many people and agencies assisted in gathering data in the field and in providing analyses over a period of 40 years. Although greater than 9 visits were necessary to obtain a near-complete count of marmots in a colony, two to four counts usually detected 65 to 75% of the animals present. 7: 201 to 204. Bunnell, F.L. Food addition in the spring has been used to draw marmots away from roads at Mount Washington. Blumstein, D.T., B.D. Ministry of Environment Wildlife Bulletin B-39, Victoria, B.C. Long term, the amount of natural habitat available to Vancouver Island Marmot is decreasing; climate change has resulted in forests replacing subalpine meadow habitat. Ministry of Environment, Victoria, B.C. Porter. Kamloops, British Columbia. Marmots also live in Strathcona, Schoen Lake, and Clayoquot Plateau Provincial Parks, all of which are afforded habitat protection under the B.C. Recovery strategy for the Vancouver Island Marmot (Marmota vancouverensis) in British Columbia. 174 to 219 in A.D. MacMillan and D.E. In 2003, there were fewer than 30 Vancouver Island marmots in the wild. Marmots found in unsuitable habitat (for example, cut-blocks) are relocated to currently or recently occupied colonies or taken into the captive-breeding program. Vancouver Island marmots usually have litters of 3 to 4 pups, though litter size can range from 1 to 7. One excavated hibernation burrow measured five meters in length with the sleeping chamber located one meter underground. From 2012 to 2017, marmots were not bred at the Mount Washington Recovery Centre, but the Centre temporarily housed captive marmots scheduled for release. Edited by T.D. Population size of captive Vancouver Island Marmot. Vancouver Island Marmot project final report, 2013. Reproduction and persistence of Vancouver Island Marmots (Marmota vancouverensis) in natural and logged habitats. Spring feasts begin with grasses, sedges and phlox and graduate to lupines and other forbs later in the season. Date Designated: May 30, 1991 Purpose: Management of critical habitat for the Vancouver Island Marmot. The call appears to function as a low-level alarm that is used to communicate uneasiness in response to a disturbance, such as after a predator has left the area. Molecular data resolve placement of the Olympic Marmot and estimate dates of trans-Beringian interchange. September, 2016. Web site: COSEWIC. In addition, individual predator behaviour can vary among locations. Morrison, C.D., M.S. Dispersal and gene flow are less for small colonies, increasing genetic drift and the potential for inbreeding depression. Through the mid-late 1990's (Janz et al. Release of captive-born marmots to these and additional mountains has resulted in the species successfully occupying 31 different mountains in recent years; 17 mountains in the Nanaimo Lakes area, 12 mountains in the Strathcona Park area, and one mountain each in Schoen Lake and Clayoquot Plateau (Figure 2). The three-generation population trend (2001 to 2017) for mature individuals was positive, but non-linear (Figure 7). The typical herbicide is glyphosate with spot application through backpack sprayer. ): Re-introduction News. Criterion D (Very small or restricted population): Meets endangered D1 as there are fewer than 250 mature individuals. Melcher J.C., K.B. Page. Between 1972 and 1995, marmots or fresh burrows were reported from 15 mountains (Bryant and Janz 1996). Vancouver Island Marmot population and habitat viability assessment workshop final report. Like other alpine-dwelling marmot species, Vancouver Island Marmot is limited by low reproductive output. 2011, Kerhoulas et al. Spreading the marmots around in several smaller colonies guards against a total collapse of the species if any one colony should suffer a catastrophic event. Bichet, C., S. Sauzet, L. Averty, P. Dupont, M. Ferrandiz-Rovira, C. Ferrari, I. Figueroa, M. Tafani, C. Rézouki, B.López, and A. Cohas. The negative effects have and can be mitigated through removal of these trees. Brashares, J.S., J.R. Werner, and A.R.E. Social “meltdown” in the demise of an island endemic: Allee effects and the Vancouver Island Marmot. 2018). The peak of 85 occurred in 2010 when the captive population was being downsized. Vancouver Island Marmot Recovery Team. Despite large amounts of potential habitat created by logging above 700 m, only a small fraction was ever colonized and colonies in cut-blocks became extirpated 5 to 19 years post-colonization. Buttle Lake may be a barrier to dispersal or force marmots to disperse further to get around the lake; marmots have been document to disperse around the western end of the lake. Vancouver Island marmot, M. vancouverensis endemic to Vancouver Island, British Columbia, Canada Yellow-bellied marmot , M. flaviventris found in southwestern Canada and western United States Additionally, four extinct species of marmots are recognized from the fossil record: 2016), so to achieve ~ 25 effective releases, ~ 63 captive marmots would have to be released annually to reverse a severe decline. Vancouver Island Marmot requires deep colluvial soils; these loose, unconsolidated sediments found at the bottom of steep slopes are suitable for burrow construction. B.C. 1 to 12 pp. British Columbia’s most famous marmot, and Canada’s most endangered mammal, the Vancouver Island Marmot can be found only on Vancouver Island. 56:497 to 511. Ottawa, ON Kerhoulas, N.J., A.M. Gunderson, and L.E. 2015. These activities appear to have few negative effects, although there is always a small risk that a marmot could be hit by a mountain bike or a dog accompanying a hiker could kill a marmot or transmit a disease. French name: Marmotte de l’île de Vancouver, Range of occurrence in Canada: British Columbia (Vancouver Island). They concluded that for colonies visited once, observers probably counted 40 to 60% of adults present, depending upon time of year. Vortex: A stochastic Simulation of the Extinction Process. Amish, and W. Pinsker. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. 2017. Jackson, C., personal communication 2017a. Jackson, C. 2014. Chart illustrating population trend for Vancouver Island Marmot from 1972 to 2017. Negative effects of habitat alteration, in the form of tree growth, have occurred and are expected to be large on a 20-year time scale (that is, increased forest cover decreases the quality of habitat by increasing risk of predation). Stanford University Press, Stanford, California. Stress level, as measured by hair cortisol, is higher, however, for newly released captive-born marmots (Acker 2018). 2017. Ministry of Forests and B.C. Mount Washington is at lower elevation and the marmots live in open areas (ski trails) surrounded by trees. The potential effects of climate change on the habitat range of the Vancouver Island Marmot (Marmota vancouverensis). As its name suggests, the Vancouver Island marmot only lives on the Island. An adult marmot may stand at 13-18 cm (5.1-7.1 in) at the shoulder. Kruckenhauser, L., W. Pinsker, E. Haring, and W. Arnold. 2018. Fish and Wildlife: This small WMA contains vital habitat for the critically endangered Vancouver Island Marmot. Kerhoulas, N.J., A.M. Gunderson, and L.E. Her past research involved the population dynamics and behaviour of microtine rodents (Nova Scotia), Snowshoe Hares (Yukon), Arctic Ground Squirrels (Yukon), and American Dippers (British Columbia). B.C. 2008. Munro, W.T. Environmental Research Scholarship Committee, Victoria, British Columbia. Humans recreating near marmot colonies probably benefit marmots because marmot predators may avoid areas of high human use. Occasional Paper #4. 1911. Holland, and J.C. Daniel.
