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. Between 2006 and 2013, there were 10 natural dispersal events among the colonies in the Nanaimo Lakes subpopulation, with 50% of these dispersers eventually breeding where they settled (Jackson and Doyle 2013) and in 2015, two new mountains in the Strathcona subpopulation were naturally colonized by dispersers (Jackson and Lester 2015). Inouye, D.W., B. Barr, K.B. They are also transported by air, and may encounter other mammal species in cargo holds. 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. U.S. Ottawa. The vulnerability of Vancouver Island Marmot to predation might increase if they remain active later in the fall or emerge earlier in the spring. Senior Wildlife Biologist, Ministry of Forests, Lands, Natural Resources and Rural Development, Government of British Columbia, Nanaimo. August, 2017. Two models were constructed to explore the extremes in demographic rates observed for the Nanaimo Lakes subpopulation. If mitigation continues, there is the potential for a positive effect through enhancement and creation of habitat. From 2000 to 2017, the captive population weaned 597 marmot pups and from 2003 to 2017, 490 marmots were released. Kerhoulas, N.J., A.M. Gunderson, and L.E. In 1972, naturalists, government personnel, and researchers began surveying mountains on Vancouver Island for marmots, which until that date were known from only a handful of museum specimen records (Bryant and Janz 1996). Stanford University Press, Stanford, California. 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. In 1978, COSEWIC designated its first species and produced its first list of Canadian species at risk. At the end of 2017, there were 49 marmots in the captive population, including 19 pups. The British Columbia Park Act affords habitat protection to marmots living in Provincial Parks. Munro, W.T., D.W. Janz, V. Heinsalu, and G.W. Ministry of Environment, Lands and Parks, Victoria, British Columbia. MacDonald. More recently, there was high mortality due to Cougar (Puma concolor) predation at another location. 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). Cut-block colonies, however, would probably go extinct within 5 to 19 years (Bryant 1996, 1998). 4. Vancouver Island Marmot is culturally important to Indigenous people on Vancouver Island. Theytus Books, Nanaimo. She obtained her B.Sc. Vancouver Island Marmot was hunted by Indigenous people as evidenced by cut marks on marmot bones found at four archeological cave/rock shelter sites on Vancouver Island (Nagorsen et al. Description . The trend of decreasing habitat is expected to continue with a prediction that under a “worst case” scenario up to 97% of current marmot habitat may disappear by 2080. Dispersers are most frequently two-year-old males and females. 17 pp. Like other alpine-dwelling marmot species, Vancouver Island Marmot is limited by low reproductive output. 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. Email. Most recent colonies in natural habitats are small, typically containing one or two family groups and fewer than five adults (Bryant and Janz 1996). Committee on the Status of Endangered Wildlife in Canada. Bryant, A.A., and D.A. 2018). 2000. Kuhnlein, H.V., and M.M. 2017. It is notable for its chocolate brown fur, unique vocalizations, atypical skull characteristics, and highly social nature. Hooper. An adult marmot may stand at 13-18 cm (5.1-7.1 in) at the shoulder. 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. Ministry of Environment, Victoria, British Columbia. Its Subalpine meadow vegetation of south central Vancouver Island. 1996). worldwide, and is the only marmot native to Vancouver Island. Vancouver Island Marmot was assessed as endangered by COSEWIC in April 1978, April 1997, May 2000, April 2008, and May 2019. 2011, Yan et al. Genetic variation within Vancouver Island Marmot is low compared to other species of marmots (estimated heterozygosity (He) 8 to 23%; Kruckenhauser et al. 31 to 65 in J.B. Nyberg and D.W. Janz (eds.). The Mammals of British Columbia, Vol. Two new species of marmots from Northwestern America. A successful captive-breeding program and resulting population supplementation has been reduced. Province of British Columbia. When alarmed, marmots give piercingly loud whistles, which earned them the nickname “Whistle Pig”. Vancouver Island Marmot requires deep colluvial soils; these loose, unconsolidated sediments found at the bottom of steep slopes are suitable for burrow construction. The predicted population decline and resulting probability of extinction varied considerably according to scenarios that represented a combination of reduced mortality and various levels of supplementation through captive breeding. Endangered 2019. 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. Marmots at a geographically disjunct mountain (Mount Washington), however, had been isolated for at least several generations based on DNA analysis (Kruckenhauser et al. During the population collapse of the 1990s, the Haley Lake colony (Heard 1977, Bryant 1996) declined from 25 to 10 marmots in 1994 to 1995. These larger groups of colonies are called metapopulations. As its name suggests, the Vancouver Island marmot only lives on the Island. [accessed December 2017]. 2015, Graham personal communication 2018); all would facilitate the maintenance of genetic diversity in the captive and wild population. Vancouver Island marmots live in small colonies in the subalpine parkland. Vancouver Island Marmot also uses forested areas as low as 700 m above sea level where clearings that mimic natural meadows are created by anthropogenic activities such as logging, mining developments, and ski facilities. Roach, N. 2017. Emergence from hibernation of Yellow-bellied Marmot was correlated with the date of snowmelt at a study site in Colorado; in 2014 they were emerging 30 days earlier than in 1976 (Inoue et al. Thanks to the work of conservationists, Vancouver Island marmots, a chunky relative of the common squirrel, have seen their numbers grow from barely two dozen to nearly 200. With sufficient funding, any marmots that would be directly affected by the flooding of burrows could be moved. Stress levels of marmots, as measured by hair cortisol concentration, is lower for marmots living in captivity than marmots in the wild (Acker 2018). Each colony will have an adult male, one or more adult females and several sub-adults such as yearlings and new-borns. 2009) which implies the population has been small for an extended period. Kenagy, C. Zawadzki, R. Robles, E.A. Some of the land on Mt. The behavior of Vancouver Island Marmots (Marmota vancouverensis). Marmots lose approximately 30% of body mass during hibernation (Bryant and McAdie 2003). It is notable for its chocolate brown fur, unique vocalizations, atypical skull characteristics, and highly social nature. = 142), of which 91 (min. Conservation Genetics 10:1759 to 72. They have a deep brown body, with distinctive white patches on the face and chest, most prominently on the nose. Family: Sciuridae Ministry of Forests and B.C. Many marmots colonized and reproduced successfully in human-altered habitats. If logging occurred in this part of Mount Washington, it is unknown how the marmots that use the hibernacula within this forested habitat would respond. Email Correspondence to E. Gillis. For the counts of the total population and mature marmots, the minimum and maximum values averaged 13.1% (SD = 6.1%, n = 8) and 15.2% (SD = 5.6%, n = 8) below and above the reported count, respectively. Sites with solitary marmots are also shown. The landowner has wanted to harvest this area for approximately 15 years but has chosen not to because of the potential impact on the marmots. Metapopulation ecology of Vancouver Island Marmots (Marmota vancouverensis). Thelin et al. More recently (2017), there was high mortality due to Cougar predation at another location.
