Even though there was evidence of at least two genetically distinct, geographically isolated subpopulations (Strathcona and Nanaimo Lakes), the risk of future inbreeding depression associated with low genetic diversity led to the decision to maximize genetic diversity by cross-breeding individuals from the two subpopulations in the captive-breeding program (Kruckenhauser et al. Metapopulation dynamics of Vancouver Island Marmots (Marmota vancouverensis). Committee on the Status of Endangered Wildlife in Canada. One excavated hibernation burrow measured five meters in length with the sleeping chamber located one meter underground. Bryant, A.A. 1996. Theytus Books, Nanaimo. Dispersing marmots have in the past created colonies in clearcuts, as early successional forests mimic alpine meadows. Vancouver Island Marmot was assessed as endangered by COSEWIC in April 1978, April 1997, May 2000, April 2008, and May 2019. Its current known distribution is limited to 25 mountains in four locations on Vancouver Island: 14 mountains in Nanaimo Lakes, nine mountains in Strathcona, and one mountain in each of Schoen Lake and Clayoquot Plateau. In 2017, augmentation of the Nanaimo Lakes subpopulation with captive-released and wild marmots (translocated from cut-blocks) resumed; these individuals were not included in the 2017 numbers presented for Nanaimo Lakes. 2015) with five mountains receiving supplementation in 2017 (Jackson personal communication 2017a).

COSEWIC. The species was listed as endangered under the B.C. Fish and Wildlife Service. No. In 2017, five marmots (one adult female and four yearlings) in cut-block colonies and one dispersing marmot were trapped and moved to natural colonies (Jackson personal communication 2017a). Small, simple burrows may be used for a quick escape from a predator and larger more complex burrows are used for hibernation and birthing and may have numerous passages and exits. Vancouver Island Marmot Recovery Team. The major immediate threat to Vancouver Island Marmot is predation by native species (Cougar, Grey Wolf, and Golden Eagle) with an estimated impact of High to Low. Getting back to normal: space use and behaviour of reintroduced and wild Vancouver Island Marmots. Most recent colonies in natural habitats are small, typically containing one or two family groups and fewer than five adults (Bryant and Janz 1996). 2017b. Some marmots were held overwinter and during the active season while others were held for a quarantine period of at least 30 days before release (Jackson et al. Genus: Marmota Subalpine meadow vegetation of south central Vancouver Island. 2019. Monitoring of radio-tagged Cougar and Grey Wolf supported this hypothesis as some individual predators repeatedly returned to hunt in the same meadows. Indeed, the marmot population in the wild has increased in the recent past. K1A 0H3, Tel. The Vancouver Island marmot (Marmota vancouverensis) is the rarest of all the North American species of marmot; it exists solely on Vancouver Island. 1999. 1990. Predation by native predators (Cougar. Ministry of Environment Wildlife Bulletin No. Marmota vancouverensis. Également disponible en français sous le titre Évaluation et Rapport de situation du COSEPAC sur la Marmotte de l’île de Vancouver (, , in the Qinghai-Tibet Plateau.” PLoS One 12 (8):e0183375, Species at Risk Act: COSEWIC assessments and status reports, Wildlife species description and significance, Acknowledgements and authorities contacted, Appendix 1. Size: 300 hectares Region: West Coast NATURE AND CULTURE . Thorington. Stress level, as measured by hair cortisol, is higher, however, for newly released captive-born marmots (Acker 2018). Each colony was visited 1 to 49 times (median = 6.5, n = 16; Jackson personal communication 2017b). Marmots commonly react to these species, as well as small raptors, deer, and elk, which pose no threat, by whistling or by fleeing into burrows. Based on all hibernacula and colonies that have been occupied within the last 10 years, the extent of occurrence was 5,653 km2 (Figure 3). A gathering project may be conducted if there are information gaps, or if ambiguity exists between ATK and other forms of knowledge. Learn more about this special animal, its habitat, and challenges it faces. Fish and Wildlife Compensation Program. The potential effects of climate change on the habitat range of the Vancouver Island Marmot (Marmota vancouverensis). Since 2013, however, the total number of marmots has declined every year. Nielsen, and M.M. For the writing of the report, the Marmot Recovery Foundation provided access to their unpublished data, and Cheyney Jackson, Malcolm McAdie, and Adam Taylor assisted in facilitating the data transfer and interpretation. Blumstein, D.T. Marmot Recovery Foundation. Kamloops, British Columbia. 2011, Kerhoulas et al. More recently (2017), there was high mortality due to Cougar predation at another location. in early spring, with a shift to forbs, especially Broad-leaved Lupine (Lupinus latifolius) and Sunflower (Eriophyllum lanatum) in summer and fall. The probability of extinction (PE100) remained low across a range of values for carrying capacity and initial population size. In 2003, only 30 of these small, furry animals were thought to remain in the wild. Marmots have large beaver-like teeth, sharp claw… The loss of genetic variation could be mitigated through occasional translocation of individuals between subpopulations. 31 pp. [accessed December 2017]. 2015. Underground burrows provide shelter from the elements and protection from predators. Mating occurs below ground in May, shortly after waking from hibernation. Ministry of Environment, Victoria, B.C. Description . Version 10.0. The Vancouver Island marmot, Canada’s most endangered mammal, is only found in the wild on Vancouver Island mountains. 2006. I studied the social behaviour of the Vancouver Island marmot, Marmota vancouverensis, during the summers of 1973 and 1974. Jackson, C., S. Johnson, C. White, and D. Doyle. In 2003, the wild Vancouver Island Marmot population dipped below 30 individuals, but with recovery … Heard, D.C. 1977. Update COSEWIC status report on the Vancouver Island marmot Marmota vancouverensis in Canada. Females can weigh as low as 3 kg emerging from hibernation and males can weigh as much as 7 kg after foraging throughout the summer months. 2011, Yan et al. Further to the Terms and conditions for this website, some of the photos, drawings, and graphical elements found in material produced by COSEWIC are subject to copyrights held by other organizations and by individuals. For example, a litter may have appeared to have six pups, but only four pups were observed during the field observation. For example, in 2017, field crews of one to eight people visited 16 of the 25 mountains known to have active marmot colonies. Mount Washington had at least 47 to 58 marmots in 2013; this dropped to 31 in 2017. 2015). 6 pp. Visits to most known colonies occur annually, with the number and duration of visits being variable. B.C. Such impacts could be mitigated through forest management (for example, selective tree clearing in old avalanche chutes). In general, Vancouver Island marmots appear to select hibernacula that are covered during winter by deep snow. COSEWIC assessment and update status report on the Vancouver Island marmot Marmota vancouverensis in Canada. Marmot biology: Sociality, Individual Fitness, and Population Dynamics. It is notable for its chocolate brown fur, unique vocalizations, atypical skull characteristics, and highly social nature. They can turn from sleek to pump in a matter of a few months. It is notable for its chocolate brown fur, unique vocalizations, atypical skull characteristics, and highly social nature. Thelin, L., J. Lewis, A. Gilchrist, and J. Craig. The behavior of Vancouver Island Marmots (Marmota vancouverensis). Overwinter survival of captive-released marmots in their first winter in the wild is <40% (Jackson et al. Jackson, C., personal communication 2016b. Field Coordinator, Marmot Recovery Foundation, Nanaimo, British Columbia. In fall 2018, the Mount Washington Recovery Centre re-opened as a year-round captive breeding facility. Hibernation permits the marmots to survive the long alpine winters when food is not available. The primary immediate threats to Vancouver Island Marmot are predation by native predators and ecosystem modification that results from logging and wood harvesting (based on the IUCN-CMP unified threats calculator; Vancouver Island Marmot Recovery Team 2017). 2008. BC Hydro Fish and Wildlife Compensation Program. Marmot Recovery Foundation. 1983. Ottawa. 35 to 45%, n = 424) of breeding pairs successfully wean litters (Figure 4). Jackson, C. 2014. When the marmot population collapsed during the 1990s, it was often the areas with the highest density that declined first. The maximum observed age is 12 years in the wild and 14 years in captivity. It is endemic to Canada - one of only a small handful of mammals to occur in this country and nowhere else. 2015). Vancouver Island Marmot shares many life history characteristics with other alpine marmots; they are social, rely on a burrow system for protection from predators and adverse weather, and all have a predictable annual cycle highlighted by a hibernation period and an active season (Barash 1989, Amritage 2014). If a disease outbreak occurred at any of the four locations, it could impact all the colonies at that location. The population declined precipitously during the 1990s, with only ~70 individuals remaining in the wild by 1997. 1911. Nielsen, and M.M. Number of Cities: About fifty towns and cities are on Vancouver Island. Bio.,Unit Head, Species Conservation Science, BC Ministry of Environment), Sean Pendergast (R.P. There are two groups of workers that would frequent marmot colonies - marmot researchers and employees of the Mount Washington ski resort. 72 pp. Keeley T., L. Graham, A. Campbell, C. Howell, and S. MacDonald. The Canadian Wildlife Service, Environment and Climate Change Canada, provides full administrative and financial support to the COSEWIC Secretariat. 1981. Federal Register. 2005) and a unique vocalization (Heard 1977, Blumstein 1999). August, 2017. Genetic evidence for subspecies differentiation of the Himalayan Marmot, Marmota himalayana, in the Qinghai-Tibet Plateau.” PLoS One 12 (8):e0183375. Environ. An adult Vancouver Island marmot typically measures 65-70 centimeters from nose to tip of its bushy tail. The Vancouver Island marmot is considered one of the rarest animals in North America and their wild population numbered fewer than 30 in 2001. COSEWIC. The minimum represented the number of unique individuals either seen by researchers or detected alive by telemetry during the active season. Order: Rodentia In cases where Vancouver Island Marmot colonies exist on crown land leased to forestry companies or private lands owned by forestry companies or alpine resorts, the lands are managed with active and ongoing consultations among the lease or land owner, the Marmot Recovery Foundation and the Vancouver Island Marmot Recovery Team (Vancouver Island Marmot Recovery Team 2017). 2015, Graham personal communication 2018); all would facilitate the maintenance of genetic diversity in the captive and wild population. Marmots have large beaver-like teeth, sharp claws and powerful shoulder and leg muscles for digging. Temperature extremes may also reduce snow pack persistence and whether winter precipitation is snow or rain, both of which may affect the metabolic cost of hibernation and overwinter survival. Therefore, to increase genetic diversity in the captive population an additional seven individuals from the wild population were brought into captivity in 2016 and 2017 (Figure 8). The Vancouver Island marmot pups were born at the Devonian Wildlife Conservation Centre, the zoo announced Thursday. Considering just the first two generations, the population increased by 1332 or 731%. Endangered species, 88 to 101 in wild pop (includes captive-born marmots that have survived at least 1 hibernation in wild), Reproduction was confirmed by observation, Mountain that had a typical survey effort but no pups were detected, The most recent year adult marmots were confirmed at mountains where adults were not confirmed in 2016, Moderate (Possibly in the short term, < 10 yrs/3 gen). Its At the time of the threat assessment, there were no run of the river or wind projects that were likely to affect marmots. 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. Graham, L., personal communication 2018. Bryant, A.A. 1996. Metapopulation ecology of Vancouver Island Marmots (Marmota vancouverensis). Results from the stochastic population model suggested that under conditions of high wild survival, captive-released marmots would not be required for demographic rescue. French name: Marmotte de l’île de Vancouver, Range of occurrence in Canada: British Columbia (Vancouver Island). 2017. If there is a negative effect, it is unknown if it would affect only the marmots currently residing there or if marmots in the future would also use these hibernacula and be negatively impacted. A marmot with a radio transmitter was excluded from the count if it was detected alive during the year, but its transmitter subsequently emitted a mortality signal prior to hibernation. Marmots also live in Strathcona, Schoen Lake, and Clayoquot Plateau Provincial Parks, all of which are afforded habitat protection under the B.C. 1 to 12 pp. To do this, partial disparities (Foote, 1997; Zelditch et al., 2004) of shape and size are computed, standard errors are estimated by bootstrap, and species are com-pared to test whether divergence in M. vancouverensis is Pp. In 2004, fewer than 30 remained in the wild. Unpublished report. With the exclusion of Mount Washington, in 2013, there was an average 10.0 (SD = 10.3, range = 1 to 46, n = 29) marmots on each mountain where marmots were detected. The Vancouver Island marmot is a unique species of mammals, found wild in the hilly areas of Vancouver Island in British Columbia, Canada. Find out more about this species.. Deer and Elk Habitats in Coastal Forests of Southern British Columbia. Vancouver Island Marmot is one of only five endemic species of mammal in Canada (Naughton 2012). 2015). Evidence of exposure was found, but any toxins found were at very low levels and do not raise any concerns. The Vancouver Island marmot is one of 14 marmot species found around the world and one of the five mammal species endemic to (found only) in Canada. Acker, M.J. 2018. Recently logged habitats may also negatively affect the population if dispersers settle and create colonies in these habitats. Phylum: Chordata Each sub-population is composed of a cluster of 1 to 14 mountains, with each mountain home to one or more colonies. Results suggested that Vancouver Island Marmot had a high probability of persistence if survival rates were consistent with the observed growth of the population. TimberWest, Island Timberlands, and Mount Washington Alpine Resort permitted the use of spatial data of Vancouver Island Marmot on their private lands, and Larissa Thelin and Jenny Wu calculated the extent of occurrence. The maximum straight-line dispersal distance recorded for a wild-born marmot is 31 km although in 2015 an untagged adult male Vancouver Island Marmot was trapped in Bamfield, greater than 60 km from the nearest known colony (Marmot Recovery Foundation 2015, Pendergast personal communication 2015). = 127, max. Also, following normal successionary processes, including planting and regrowth of trees, cut-blocks become unsuitable as marmot habitat. Social “meltdown” in the demise of an island endemic: Allee effects and the Vancouver Island Marmot. Traditional Animal Foods of Indigenous Peoples of Northern North America. Roughly the size of a house cat, these members of the rodent family are extremely sociable, often seen greeting one another with nose-touching and play fighting. In 2017, there was high Cougar predation at the Nanaimo Lakes subpopulation. These years corresponded to three years of summer drought conditions on Vancouver Island and relatively little supplementation with captive-bred marmots (Figure 6). Finally, fewer Vancouver Island Marmots and marmot colonies on the landscape also decreases the probability that a naturally dispersing marmot will encounter a colony; therefore, small population size may force marmots to travel longer dispersal distances than in the past. The colonies are made up of one or more families consisting of an adult male, one or more adult females and a variable number of sub-adults, yearlings and young-of-the-year. Hibernacula can be identified either by the grass and mud “plugs” found at tunnel entrances in late autumn, or by emergence tunnels through the snowpack in May or early June. Boyce, S.E. Conserv. Vancouver Island Marmot requires deep colluvial soils; these loose, unconsolidated sediments found at the bottom of steep slopes are suitable for burrow construction. New fur is particularly dark and almost black in young of the year. There may be some short term negative impact of trail creation, but this will be negated by a longer term net benefit to marmots because the cleared areas, if maintained, will increase the amount and quality of habitat for marmots. Marmot Recovery Foundation, Nanaimo, BC. About the size of a house cat and weighing around 5 kg pre-hibernation, the Vancouver Island Marmot is the largest member of the squirrel family. Marmots live on ski hills, near mountain biking trails, and in alpine areas popular for hiking. Kingdom: Animalia Genetic variability and minimum viable populations in the Vancouver Island Marmot, Marmota vancouverensis. Through the mid-late 1990's (Janz et al. (2018) estimated that only 9.6% of Vancouver Island is currently covered by suitable marmot habitat. SARA establishes COSEWIC as an advisory body ensuring that species will continue to be assessed under a rigorous and independent scientific process. Animal Conservation 9: 274 to 282. Vancouver Island Marmot Fast Fact: In the wild this particular marmot will hibernate for about 210 days. Endangered and threatened wildlife and plants: final rule to list 10 foreign mammals as Endangered species, and withdrawal of 1 species. The size and number of families varies between colonies and years, often producing dramatic fluctuations in population size in a given location. Problematic species/diseases of unknown origin. 2010. Bryant (2005) reported the following: "Population counts began in 1979 and have continued, with variable coverage and intensity, until the present. For most colony-year combinations with two or more visits in June and July, observers probably saw 66 to 78% of adults, and 75 to 89% of young. Natural habitat consists of subalpine meadows that generally occur at 900 to 1500 m, normally on steep (30 to 45°) south- to west-facing slopes (Bryant and Janz 1996), although a recent analysis using GIS and hibernacula spatial data estimated that up to 60% of current colonies may be located on slopes of less than 30° and >25% of slopes may have an easterly aspect (Thelin et al. Centre for Indigenous Peoples’ Nutrition and Environment, McGill University, Montreal. An adult marmot may stand at 13-18 cm (5.1-7.1 in) at the shoulder. size and shape) is measured. Werner, J.R. 2005. A fourth facility, the Mountain View Conservation and Breeding Centre in Langley, British Columbia, housed and bred Vancouver Island Marmot from 2000 to 2013. Habitat selection of a re-colonized cougar population in response to seasonal fluctuations of human activity. Unpublished report to B.C. Vancouver Island Marmot population and habitat viability assessment workshop final report. A survey of 97 mountains with each classified in terms of habitat suitability for marmots was also conducted by Routledge and Merilees (1980). Canadian Field-Naturalist 100:241 to 245. 2012. 2016b. Even though there was evidence of at least two genetically distinct, geographically isolated subpopulations (Strathcona and Nanaimo Lakes), the risk of future inbreeding depression associated with low genetic diversity led to the decision to maximize genetic diversity by cross-breeding individuals from the two subpopulations in the captive-breeding program (Kruckenhauser et al. Metapopulation dynamics of Vancouver Island Marmots (Marmota vancouverensis). Committee on the Status of Endangered Wildlife in Canada. One excavated hibernation burrow measured five meters in length with the sleeping chamber located one meter underground. Bryant, A.A. 1996. Theytus Books, Nanaimo. Dispersing marmots have in the past created colonies in clearcuts, as early successional forests mimic alpine meadows. Vancouver Island Marmot was assessed as endangered by COSEWIC in April 1978, April 1997, May 2000, April 2008, and May 2019. Its current known distribution is limited to 25 mountains in four locations on Vancouver Island: 14 mountains in Nanaimo Lakes, nine mountains in Strathcona, and one mountain in each of Schoen Lake and Clayoquot Plateau. In 2017, augmentation of the Nanaimo Lakes subpopulation with captive-released and wild marmots (translocated from cut-blocks) resumed; these individuals were not included in the 2017 numbers presented for Nanaimo Lakes. 2015) with five mountains receiving supplementation in 2017 (Jackson personal communication 2017a). Yes (in Sept 2016 for the BC Ministry of Environment), Overall threat impact: Medium–high Masters of Environmental Science Showcase. This report was overseen and edited by Chris Johnson and Graham Forbes, Co-chairs of the COSEWIC Terrestrial Mammals Specialist Subcommittee. Senior Biologist, TimberWest, Nanaimo, British Columbia. The population decreases resulted in an average 50% reduction in the number of marmots per mountain. Olson. Morphological evolution in marmots (Rodentia, Sciuridae): size and shape of the dorsal and lateral surfaces of the cranium. On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. Bryant, A.A. 1998. From 2008 to 2012/2013, the number of marmots tripled due to reproduction in the wild and the release and recruitment of captive-born marmots into the wild population. Armitage, and B.D. Previous report(s): COSEWIC. The proximate cause of the decline was increased predation. Transactions of the North American Wildlife and Natural Resources Conference.
