Ministry of Environment, Victoria, B.C. Ottawa. Total populations for any one year are subdivided to show proportion of: wild-living marmots (wild-born marmots and captive released marmots that survived at least one hibernation in the wild); captive releases that survived until their first hibernation; marmots removed from the wild to establish and augment the captive breeding population. Cortisol and conservation: understanding barriers to the recovery of a critically endangered species using stress physiology. Nose – touching (“greeting”) and play fighting (“boxing”) are common behaviours and very entertaining to watch. Holland, and J.C. Daniel. Min. Vancouver Island marmots are easy to recognize by their rich chocolate brown fur with contrasting white patches on their nose, chin, forehead and chest. (2018) estimated that only 9.6% of Vancouver Island is currently covered by suitable marmot habitat. 2008. Environment and Climate Change Canada In contrast, over a 10 year time scale, collection of marmots for captive breeding will have a positive effect on the population because captive born marmots are released back into the wild. The behavior of Vancouver Island Marmots (Marmota vancouverensis). An adult marmot may stand at 13-18 cm (5.1-7.1 in) at the shoulder. Humphries. Jackson, C., S. Johnson, C. White, and D. Doyle. Predation by native predators (Cougar. Vancouver Island is in the northeastern Pacific Ocean, and part of the Canadian province of British Columbia.The island is 456 km (283 mi) in length, 100 km (62 mi) in width at its widest point, and 32,134 km 2 (12,407 sq mi) in area. St. Claire (eds.). Many marmots colonized and reproduced successfully in human-altered habitats. Ministry of Forests and B.C. At the end of 2017, there were 49 marmots in the captive population, including 19 pups. The Vancouver Island Marmot also inhabits recent clearcut habitats at elevations as low as 730 m (Bryant and Janz 1996). Duration of snow cover and its influence on life-history variation in Yellow-bellied Marmots. Recovery strategy for the Vancouver Island Marmots (Marmota vancouverensis) in British Columbia. Finally, Vancouver Island Marmot is a foreign mammal listed under the U.S. Learn More: Anyone who sees a Vancouver Island marmot is encouraged to report the sighting by calling 1 877 … Lindsay, D., personal communication 2017. Between 2015 and 2017, however, the mature marmot population declined by >15% per year. J. Zool. The population count was the number of individuals known or thought to be alive. Munro, W.T. M.Sc. U.S. The species is found in one National Ecological Area (Pacific) and no subspecies designation is currently recognized under M. vancouverensis (Armitage 2014). In 2003, there were fewer than 30 Vancouver Island marmots in the wild. Ninety-one (min. 2015). Canadian Journal of Zoology 59:790 to 792. 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. COSEWIC. 31 pp. In contrast, under the declining population model, PE100 was 100%. The 1980s and 1990s were also associated with a high abundance of Golden Eagles on Vancouver Island (McAdie personal communication 2016). Ministry of Environment, Victoria, B.C. Vancouver Island Marmot in captivity exhibit reproductive and many behavioral traits comparable to their wild counterparts (Bryant 2005; Blumstein et al. Interactions of timber management with deer and elk. Verbal communication to Vancouver Island Marmot Recovery Threat Assessment participants. ): Re-introduction News. Annually, backcountry hikers and Vancouver Island residents report marmot sightings to provincial biologists and the Marmot Recovery Foundation (Jackson personal communication 2017a). Res. 1983. In addition to colony visits, marmots with radio transmitters were monitored using telemetry both from the ground and air for spring emergence, movements and survival, and entrance into hibernation (Vancouver Island Recovery Team 2017). In 2003, only 30 of these small, furry animals were thought to remain in the wild. During the 1980s and 1990s, logging occurred at high elevation on Vancouver Island (Lindsay personal communication 2016). 2000, Armitage 2014). Washington is privately owned, and marmots have occupied hibernacula on this forested land for over a decade. 30 to 32 in P.S, Soorae (ed. Lindsay, D., personal communication 2016. Litter size and success varies greatly from year to year, perhaps depending on food availability, female body condition, and weather. 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. Vancouver Island Marmot is not strictly monogamous and numerous cases of polygyny have been reported (Bryant 1998). Talus slopes, used as protection from predators and weather, and rocky outcrops or boulders, used for resting and vigilance, are typically found in the habitats that marmots occupy (Heard 1977, Bryant and Blood 1999). The Mountain View facility was phased out of the captive-breeding program because of fiscal constraints (Vancouver Island Marmot Recovery Team 2017). Vancouver Island Marmot was assessed as endangered by COSEWIC in April 1978, April 1997, May 2000, April 2008, and May 2019. These larger groups of colonies are called metapopulations. Canadian Field-Naturalist 100:241 to 245. Overwinter survival of captive-released marmots in their first winter in the wild is <40% (Jackson et al. Marmots live at high elevation on steep mountains, and therefore live in areas of high avalanche risk. = 142), of which 91 (min. The potential severity is unknown and could be variable because marmots may change their behaviour and many have the option to use a nearby slope or area where conditions are not as dry. About the Vancouver Island Marmot . Vancouver Island Marmot project final report, 2013. It is similar to other alpine-dwelling marmots in its slow maturation, long life span, and complex social organization. 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. 2015). Van Vuren, D., and K.B. At the other extreme reaching 30 m in length and 136, 000 kg is the Blue Whale, the largest animal that ever lived. Out of a burrow in the ground a rodent about the size of a housecat, 5-7kg (12-14 lbs), pokes her head. These years corresponded to three years of summer drought conditions on Vancouver Island and relatively little supplementation with captive-bred marmots (Figure 6). Getting back to normal: space use and behaviour of reintroduced and wild Vancouver Island Marmots. When in danger, the Vancouver Island marmot makes a piercing whistle sound, earning it the nickname “whistle pig.” Vancouver Island Marmot is notable among marmots for its unique dark chocolate fur colour and contrasting patches of white fur on the nose, belly and top of the head (Nagorsen 2005). Small population size that increases risk posed by stochastic events; evidence Vancouver Island Marmot may be susceptible to Allee effects Buttle Lake's water level is controlled by the Strathcona Dam (water levels raised 8.5 m in 1958 with construction of dam). September, 2016. The captive population has mitigated declines in the wild population and can continue to do so. Bryant, A.A. 1996. Lyapunova, and R.S. Keeley, T., K.L. Senior Wildlife Biologist, Ministry of Forests, Lands, Natural Resources and Rural Development, Government of British Columbia, Nanaimo. in early spring, with a shift to forbs, especially Broad-leaved Lupine (Lupinus latifolius) and Sunflower (Eriophyllum lanatum) in summer and fall. Just like our grandmothers told us, “it isn’t wise to keep all your eggs in one basket.”. = 142) Vancouver Island Marmot in the wild. Yearlings generally expand their movements farther from home but usually return to hibernate with their mom a second time. Timing and causes of mortality in the Endangered Vancouver Island Marmot (Marmota vancouverensis). COSEWIC: Designated endangered in April 1978. Armitage, K.B. Endangered Species Act (US Fish and Wildlife Service 1984, 2017). They can be described as the size of a large house cat. 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). 17 pp. The extirpation of colonies in cut-blocks is not caused by marmot emigration; it is because predation of marmots in cut-blocks is higher than in natural habitat (Bryant 1996, 1998). From an evolutionary standpoint, Vancouver Island Marmot is significant in that despite having low genetic divergence from its sister species, the Hoary Marmot, morphologically it is one of the most distinct species of marmots (Cardini et al. Limited genetic differences among these three species suggest rapid, recent divergence within this clade (Kerhoulas et al. Morrison, C.D., M.S. Deer and Elk Habitats in Coastal Forests of Southern British Columbia. Bichet, C., S. Sauzet, L. Averty, P. Dupont, M. Ferrandiz-Rovira, C. Ferrari, I. Figueroa, M. Tafani, C. Rézouki, B.López, and A. Cohas. Also, there is evidence of an Allee effect when populations have fewer than 250 individuals (Brashares et al. Pp. B.C. IUCN SSC Conservation Breeding Specialist Group, Apple Valley, MN. Thelin, L., J. Lewis, A. Gilchrist, and J. Craig. As its name suggests, the Vancouver Island marmot only lives on the Island. 1 to 12 pp. Xl + 784 pp. Apple Valley, MN. Endangered Species Act. The marmot population grew considerably between 2007 and 2012/2013, at which time the population in the wild was estimated to be approximately 300 marmots distributed among at least 25 different mountains. 2015). During hibernation the marmot’s heartbeat slows to 3 0r 4 beats per minute compared to an average range of 110-200 beats per minute when they are active. These cameras often were set up to monitor feeders, which provided marmots with supplemental food in the early spring (Doyle 2011). That’s more than any other marmot species. Vancouver Island marmots live in small groups called colonies. Province of British Columbia. Like other marmot species, Vancouver Island marmots are highly social; they live in colonies, rub noses in greeting and play fight like boxers. Loss of genetic diversity associated with a small population size may increase the susceptibility of marmots to disease, but risk of exposure is unknown. c/o Canadian Wildlife Service Jackson, C. and D. Doyle. McAdie, M. 2018. The habitat of Vancouver Island Marmot is naturally fragmented, consistent with the spatial distribution of patches of high-elevation subalpine ecosystems (Bryant 1998). Conservation Genetics 10:1759 to 72. Porter. 2015) from that model resulted in an estimate of 3.19 marmots after five generations when starting with a population of 135 individuals. This gregarious and lively rodent lives in about the distribution or biology of the Vancouver the mountainous regions of Vancouver Island. Fax: 819-938-3984 Providing supplemental food (Mazuri® leaf-eater biscuits) in the spring was correlated with high reproduction at one mountain; supplemental feeding at several mountains has continued (Jackson et al. Given the low abundance of Vancouver Island Marmot, currently there is sufficient habitat for population growth, and most of the suitable habitat is protected (see Habitat Protection and Ownership). On June 5, 2003, the Species at Risk Act (SARA) was proclaimed. Marmota vancouverensis. xii + 53 pp. 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. 2009) suggest that the colonies in the Nanaimo Lakes region were connected through occasional dispersal movements. Ministry of Environment. This approach continues to be recommended based on an analysis of re-introduction successes and failures of the Alpine Marmot (Marmota marmota), an actively managed marmot species in Europe (Bichet et al. nov. (Cestoda: Anoplocephalidae). Darling (ed.). Chart illustrating the reproductive success of Vancouver Island Marmots in the wild from 2008 to 2017, as indicated by number of pups weaned, number of sites where weaned pups were observed, and ratio of pups to adults. (Species at Risk Public Registry). Committee on the Status of Endangered Wildlife in Canada. Marmot Recovery Foundation, Nanaimo, British Columbia. Since at least 2007, annual surveys have focused on occupied and recently occupied mountains, but high public awareness of Vancouver Island Marmot and its identifiable physical characteristics means that marmots typically are detected if they establish outside the survey areas. 1 to 70 pp. Wildlife Veterinarian, Marmot Recovery Foundation, Nanaimo, British Columbia. Each colony was visited 1 to 49 times (median = 6.5, n = 16; Jackson personal communication 2017b). McAdie, M. 2015. Its Wild living marmots included wild-born … The Vancouver Island marmot Marmota vancouverensis is the rarest and among the least studied of the six marmot species found in North Before the early 1970s, little was known America. Reproductive behaviour and endocrinology of the Vancouver Island Marmot for use in captive breeding programs. University of Toronto Press, Toronto, Ontario. The model predicted that high rates of predation, consistent with survival estimates observed during the most recent population decline, will cause the extinction of Vancouver Island Marmot, but this trajectory could be reversed by reducing predation or by augmenting the wild population with large numbers (> 60) of captive-born marmots annually. Pendergast, S., personal communication 2016. 2000; Bryant 1998), about 58% of the Vancouver Island Marmot population was found in clearcut habitats. Rosana Soares created the current distribution map. Marmots traveling between colonies allow new colonies to be formed and declining colonies to be replenished. Fortunately there have been some steps taken to protect this endangered species. Martell, A.M., and R.J. Milko. Most natural meadows occupied by Vancouver Island Marmot during 1972 to 2006 encompassed only a few hectares (Bryant and Janz 1996). Of these, only active ski runs provide habitat that supports colonies long term. Patterns of within and between-colony microsatellite variation in the Endangered Vancouver Island Marmot (Marmota vancouverensis): implications for conservation. Adjunct Professor, University of Guelph, Guelph, Ontario. Mail: PO Box 2332 Stn A, Nanaimo, BC, V9R 6X6 1989. Lacy, R.C., and J.P. Pollak. = 127, max. The Vancouver Island marmot is considered one of the rarest animals in North America and their wild population numbered fewer than 30 in 2001. Reproduction and persistence of Vancouver Island Marmots (Marmota vancouverensis) in natural and logged habitats. Long description Chart illustrating population trend of captive Vancouver Island Marmots from 1997 to 2017. Order: Rodentia Burrows (including hibernacula) are commonly re-used over multiple years by the same individuals and social groups (Bryant 1998). In 2003, there were fewer than 30 Vancouver Island marmots in the wild. Journal of Mammalogy 92:1028 to 37. Risograph print on Extrarough Warmwhite 175 grams Metapaper. Marmots at a geographically disjunct mountain (Mount Washington), however, had been isolated for at least several generations based on DNA analysis (Kruckenhauser et al. 2014. Grey Wolf, Golden Eagle) accounts for the vast majority of mortality in marmots. 1984. Multiple geographic origins and high genetic differentiation of the Alpine Marmots reintroduced in the Pyrenees. Population growth was the result of both reproduction in the wild and the release of captive-born marmots; a captive-breeding population was established in 1997. There they find the forage they need, deep soil for digging (hibernation burrows need to be deep enough to reach below the frost line) and large boulders to provide convenient lookout spots to watch for predators. Thelin et al. Pups, usually 3 or 4 in a litter, are not seen above ground until late June or July. These captive-born marmots were included in the wild population count once they survived one hibernation in the wild. They can turn from sleek to pump in a matter of a few months. Conservation Data Centre. Theytus Books, Nanaimo. Email. Another potential source of non-native disease is via the release of captive born marmots; both facilities where captive marmots are held are multispecies facilities, where marmots could come in contact with other mammal species, including rodents. Mammal in Canada to diversity in Marmot habitat Table 2 ) results from population.
