Losses at individual colonies can be dramatic within a single year, and spatially correlated among adjacent colonies (Bryant 2000). Lacy, R.C., and J.P. Pollak. A successful captive-breeding program and resulting population supplementation has been reduced. Canadian Field-Naturalist 100:241 to 245. 2013. In 2019, the foundation counted 60 pups; this year, it reached 46 Erin Haluschak; Oct. 27, 2020 4:30 p.m. Local News; News 2013. Distribution and abundance of Vancouver Island Marmots (Marmota vancouverensis). For each mountain, minimum and maximum numbers of individuals detected were determined. The Vancouver Island marmot population is still growing slowly and is extremely vulnerable to predation from wolves and cougars that can more easily access colonies along the logging roads puncturing high alpine forests. This is the result of a warming temperature that induces the growth of forests at higher elevations and a decrease in depth of winter snow pack, which is important for overwinter survival of marmots (Thelin et al. Elizabeth Gillis is a professor of wildlife biology in the Department of Resource Management and Protection at Vancouver Island University. Tree invasion in subalpine Vancouver Island marmot meadows. Conservation Data Centre. Vancouver Island Marmot within Strathcona, Clayoquot Plateau, and Schoen Lake Provincial Parks have additional protections extended to all wildlife in parks under the British Columbia Park Act. When dispersing between mountains, Vancouver Island Marmot must travel through lower-elevation forests. However, the population decreased by 78 or 66% over the past generation (2012 to 2017), again representing exponential and linear growth, respectively. Ninety-one (min. Recently logged areas may provide "good" marmot habitat temporarily, but it is ephemeral habitat that decreases in quality as trees start to regrow and close in. 2013. 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. 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. Vancouver Island Marmot (Marmota vancouverensis) is a colonial marmot that is closely related to Hoary Marmot (M. caligata) and Olympic Marmot (M. olympus). Bryant, A.A. 1998. Between 2015 and 2017, however, the mature marmot population declined by >15% per year. 1 to 25 pp. 10: 1 to 124. 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. Predation on marmots will be greatly affected by the number of predators in the area of colonies; the number of predators will be variable and may depend on the number and behaviour of the primary prey of the predators (deer, elk, rabbits). Vancouver Island Marmot is found at four locations at which a single threatening event could rapidly affect all individuals at a location. Vancouver Island Marmot lives at high elevation, 700 to 1500 m above sea level. Chart illustrating the breeding success, in number of litters, of Vancouver Island Marmots in captivity, from 2005 to 2017. 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. Monitoring of radio-tagged Cougar and Grey Wolf supported this hypothesis as some individual predators repeatedly returned to hunt in the same meadows. For interested participants, the workshop is complemented with a one-day hike into the spectacular old –growth Divers Lake area on Sunday September 29 (8am to 6pm). It is easier to count small numbers of radio-tagged marmots at a given colony than to count greater than 30 untagged marmots, or to read ear-tags using a spotting scope (Bryant 1996). Spatially, the Canadian distribution of Vancouver Island Marmot is composed of four geographically isolated sub-populations. 39 pp. 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. Vortex: A stochastic Simulation of the Extinction Process. Reproduction and persistence of Vancouver Island Marmots (Marmota vancouverensis) in natural and logged habitats. Bryant, A.A. 1997. Males and females may become sexually mature at age two, but most females do not breed until they reach three or four years of age (mean = 3.6 years, SD = 1.2, n = 16). 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. The negative effects have and can be mitigated through removal of these trees. 2014. Kerhoulas, N.J., A.M. Gunderson, and L.E. There is no morphological, ecological or genetic evidence to suggest that individual colonies or collections of colonies (that is, subpopulations) represent evolutionarily significant units. Metapopulation dynamics of Vancouver Island Marmots (Marmota vancouverensis). U.S. Theytus Books, Nanaimo. (2018) estimated that only 9.6% of Vancouver Island is currently covered by suitable marmot habitat. The numbers are part of a new population estimate report prepared by BC Stats. 1991. A total of 63 marmots (25 adults and 38 pups) have been taken from the wild for that program (Figure 8). Marmot Recovery Foundation, Nanaimo, BC. The Vancouver Island marmot population is still growing slowly and is extremely vulnerable to damaging bouts of predation from wolves and cougars that can more easily access colonies along the logging roads puncturing high alpine forests. BC Hydro. Cardini, A., R.S. COSEWIC status report on the Vancouver Island Marmot Marmota vancouverensis in Canada. [accessed December 2017.]. 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. The three-generation population trend (2001 to 2017) for mature individuals was positive, but non-linear (Figure 7). 1999. Hoffmann. Hunting and collecting terrestrial animals. Jackson, C. personal communication 2017b. Vancouver Island Marmot Habitat Improvement 2016 Mt Moriarty - Labour Day Lake Meadow. Overwinter survival of captive-released marmots in their first winter in the wild is <40% (Jackson et al. Vancouver Island Marmot project final report, 2013. 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). 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. 1996. [accessed December 2017]. Committee on the Status of Endangered Wildlife in Canada. Through the mid-late 1990's (Janz et al. Since the last assessment, 405 captive-born marmots have been released to the wild population; captive-born individuals released to augment wild populations have successfully weaned wild-born offspring and contributed to population growth. Thanks to recovery efforts, the wild population has been increasing in recent years. Web site: COSEWIC. Volume I. BC Ministry of Environment, Lands and Parks, and University College of the Cariboo, Victoria, British Columbia. Martell, A.M., and R.J. Milko. Additional limitations include genetic isolation and a lack of suitable habitat within dispersal distance of active colonies. Laroque, C.P. Reproduction and persistence of Vancouver Island Marmots (Marmota vancouverensis) in natural and logged habitats. Captive-release marmots move up to 20 km from the release site the year they are released (Table 3). Vancouver Island Marmot was assessed as endangered by COSEWIC in April 1978, April 1997, May 2000, April 2008, and May 2019. Wildlife Veterinarian, Marmot Recovery Foundation, Nanaimo, British Columbia. Mace, T.F., and C.D. At the end of 2017, there were 49 marmots in the captive population, including 19 pups. Marmots: Social Behavior and Ecology. 2000. Most colonization events occurred within 1 to 2 km of previously existing natural colonies (Bryant 1998), and most new colonies became much larger than those in adjacent natural habitats (COSEWIC 2008). Porter. Food addition in the spring has been used to draw marmots away from roads at Mount Washington. Inouye. ... By 2003, there were just 27 Vancouver Island marmots left in Canadas wild. The likelihood of finding additional, large colonies of marmots in natural habitat is low. Vancouver Island Marmot. Hoffmann, and R.W. COSEWIC. MSc thesis, Univ. The Vancouver Island marmot has gone through an extraordinary … Food plants observed at low-elevation cut-block colonies included grasses, Pearly Everlasting (Anaphalis margaritacea), wild strawberry (Fragaria spp. Tree invasion in subalpine Vancouver Island Marmot meadows. 2017. The Committee meets to consider status reports on candidate species. Marmot Recovery Foundation, Nanaimo, British Columbia. The natural sub-alpine meadows that these marmots rely upon have largely been affected by human activities, and the loss of those habitats has … Diet at other colonies is unknown. The habitat of Vancouver Island Marmot is naturally fragmented, consistent with the spatial distribution of patches of high-elevation subalpine ecosystems (Bryant 1998). Endangered species. Survey methods have changed over time, both because of increasing reliance on telemetry and declining populations. Cut-block colonies, however, would probably go extinct within 5 to 19 years (Bryant 1996, 1998). Utility and service lines, if maintained tree free, may benefit marmots through creation and maintenance of habitat. 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 critically endangered species has gone from a low count of just 30 wild marmots living in a handful of locations in 2003 to approximately 200 living in colonies across 20 Vancouver Island mountains by 2019. Wildlife Act and under the U.S. The population decreases resulted in an average 50% reduction in the number of marmots per mountain. Total populations for any one year are subdivided to show proportions of newly captured adults and yearlings, and newly captured pups. Vancouver Island Marmot has been given a Conservation Framework Priority ranking of 1 by British Columbia, the highest rank possible. Genetic variability and minimum viable populations in the Vancouver Island Marmot, Marmota vancouverensis. Brashares, J.S., J.R. Werner, and A.R.E. In the absence of management intervention, the number of mature marmots in the Nanaimo Lakes subpopulation increased by almost 20% between 2012 and 2013; this was followed by a major decline from 2013 to 2014. 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). In addition, emergence holes in the snow during the spring are easily identifiable and can often be spotted from the air. Senior Biologist, TimberWest, Nanaimo, British Columbia. MSc thesis, University of British Columbia, Vancouver, British Columbia, Canada. 189 to 195, in L.M. 2017a. Pp. [accessed December 2017]. In fall 2018, the Mount Washington Recovery Centre re-opened as a year-round captive breeding facility. It has the most concentrated population of cougars in North America. The peak of 85 occurred in 2010 when the captive population was being downsized. No. 2017. IUCN SSC Conservation Breeding Specialist Group, Apple Valley, MN. Criterion B (Small distribution range and decline or fluctuation): Meets endangered B2ab(v) as IAO (248 km2) is less than 500 km2, the population is restricted to fewer than five locations (a) and there is a continuing observed decline in the number of mature individuals (b(v)). In addition, individual predator behaviour can vary among locations. In April 1978, Vancouver Island Marmot was assessed as endangered by COSEWIC (Munro 1978). Prepared for the B.C. Currently, ~ 60% of active colonies are in the Mountain Hemlock and 38% are in Coastal Mountain-heather Alpine zones (Thelin et al. Vancouver Island Marmot is more closely related to Hoary Marmot, found on the British Columbia mainland, than Olympic Marmot found on the nearby Olympic Peninsula of Washington State (Steppan et al. Bryant and Janz (1996) estimated the accuracy of these surveys and found that count success was highly variable; success in detecting marmots depended on colony size, time of day, season, sex, age, and reproductive status. v + 56 pp. Vancouver Island Marmot population and habitat viability assessment workshop final report. Most females are reproductively mature at age two, but most do not breed until age three or four, producing litters of 1 to 7 pups every second year on average. 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). Using DNA to help conserve the Vancouver Island marmot with Jamie Gorrell – April 18, 2019. Jackson, C. 2014. The Vancouver Island marmot is certainly the most famous animal on Vancouver Island, and perhaps is even the most famous endangered animal in Canada. Despite challenges, 2020 good year for Vancouver Island marmot population. Apple Valley, MN. 17 pp. a Data as of end of August 2017. Nearly eight marmots (7.8) were released for every marmot brought into the captive population. 2015). Journal of Wildlife Management 78:1394 to 403. Merilees. = 142) Vancouver Island Marmot in the wild. Climate change might influence the timing of hibernation. 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. Île de Vancouver Vancouver Island ... En 2002, la population est estimée à 750 000 habitants dont presque la moitié habite dans l'agglomération de Victoria, dans le sud de l'île qui est également une capitale provinciale. Federal Register. December, 2017. BC Species and Ecosystems Explorer. 2009) indicated that prior to active management, spatially adjacent marmot colonies were connected through occasional dispersal movements. Senior Biologist, TimberWest, Nanaimo, British Columbia. Treeline dynamics on southern Vancouver Island, British Columbia. Nagorsen, D.W. 1987. A fourth facility, the Mountain View Conservation and Breeding Centre in Langley, British Columbia, housed and bred Vancouver Island Marmot from 2000 to 2013. Vancouver Island Marmot project final report, 2013. 2009). French name: Marmotte de l’île de Vancouver, Range of occurrence in Canada: British Columbia (Vancouver Island). Map showing the Vancouver Island Marmot’s extent of occurrence (5,653 square kilometres), based on successful hibernacula and colonies occupied in the past 10 years. B.C. Yan, J., H. Chen, G. Lin, Q. Li, J. Chen, W. Qin, J. Su, and T. Zhang. Marmot Recovery Foundation, Nanaimo, BC. Smith. The captive population was decreased in recent years for fiscal reasons; existing facilities are at capacity and produce 13 to 22 pups annually. In 2019, the foundation counted 60 pups; this year, it reached 46. Between 1997 and 2016, captive marmots lived to an average age of 6.4 years for males (range = 0.1 to 11.5) and 8.2 for females (range = 0.1 to 14.6; McAdie personal communication 2017). xii + 405 pp. 2000, Armitage 2014). It … You will not receive a reply. Locations of potential Vancouver Island Marmot habitats within Strathcona Provincial Park. Jackson, C., personal communication 2017a. Ministry of Environment, Victoria, BC. Thelin et al. Therefore, many of the pups are not recruited into the captive population. M.Sc. September, 2016. Laroque, C.P., D.H. Lewis, and D.J. Report on a collection of birds and mammals from Vancouver Island. Dearden, P. and C. Hall. Blumstein, D.T. Most dispersal distances, however, are less than 10 km (Table 3). Recently logged habitats may also negatively affect the population if dispersers settle and create colonies in these habitats. Two protected areas have been established specifically to protect marmot habitat – the Haley Lake Ecological Reserve (888 ha) and the Green Mountain Wildlife Critical Habitat Area (300 ha). Jackson, C., and D. Doyle. Oct. 28, 2020 12:00 a.m. Lyapunova, and R.S. The first marmot pups were born in captivity in 2000 (Bryant 2005). The population of Vancouver Island was 870,297 as of 2019. 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. Jackson, C. 2016. The most recent decline (2013 to 2017) also corresponded with a reduction in the number of captive-born marmots that were released into the wild. Each year, an average of 2.8 (SD = 3.3, n = 12) captive-born marmots and 2.8 (SD = 3.0, n = 24) wild marmots had their radio transmitters replaced because the transmitter batteries were at or past their life expectancy. 2000; Bryant 1998), about 58% of the Vancouver Island Marmot population was found in clearcut habitats. Drought can decrease forage quality and availability thereby reducing reproductive output and pup growth rate. Occasional Paper #4. Subalpine habitat is even rarer south of Lake Cowichan and in areas such as Strathcona Provincial Park (Bryant 1993). Despite the appearance of sufficient suitable habitat for marmots, much of this habitat is not within natural dispersal distance of extant colonies, making it inaccessible to wild marmots (Bryant and Janz 1996). The Vancouver Island Marmot also inhabits recent clearcut habitats at elevations as low as 730 m (Bryant and Janz 1996). Fifty-five of these were brought into captivity from 1997 to 2004 and an additional eight wild-born marmots were brought into the captive population in 2016 and 2017 to increase genetic diversity in the captive population.
