I AM CANADIAN!
Toronto, Ontario, July 8, 2004: North America’s most endangered mammal is
small, furry, cute … and Canadian. Found only on Vancouver Island, less
than 30 individuals remain in the wild. The good news is that due to innovative
techniques, the Toronto Zoo has been able to captive breed this species with 11
marmot pups born in 2004, or approximately 10% of the world’s population, and
that most of these pups could be up for wild release as early as 2005.
Vancouver Island marmots, members of the squirrel family, have rich chocolate brown fur with contrasting white patches. Their rapid decline may be due to forestry, which has concentrated them in small areas, making them more vulnerable to predators, disease, and changes in climate and vegetation. Once marmots have been released back into their native habitat, they will be monitored carefully by telemetry to ensure their well being.
In conjunction with the Vancouver Island Marmot Recovery Team, the Toronto Zoo, which accepted 6 marmots in 1998, was the first zoo to establish a captive-breeding program for these animals with the goal of releasing them back into their wild habitat. Since marmots don’t become sexually mature until the age of 4 years, and in the wild reproduce only every other year, marmot reproduction presents some problems. But by using a technique called fecal hormonal analysis to gain an understanding of the females’ reproductive cycle and by implementing several other innovative methods, Toronto Zoo staff scored breeding success. "Breeding decisions made here have influenced other programs," comments Colette Howe of the Toronto Zoo’s Vancouver Island Marmot Recovery Project.
In the works for the fall of 2004, is a new Education Outreach Program, which
will spread the word about this species’ plight. The Program’s stress on
endangered species is an excellent fit with current Grade 6 curriculum.

VANCOUVER ISLAND MARMOT FACT SHEET Marmota vancouverensis |

Vancouver Island Marmots at Toronto Zoo: The Zoo currently has 9 male marmots, 6 females and 11 pups. A total of 20 pups have been born here, with 11 births in 2004. The Vancouver Island marmots are in a restricted breeding facility and are not on display to the public.
Description:
This species, members of the squirrel family, has shiny chocolate brown fur with white on the muzzle and abdomen.Distribution and Habitat: They are only found on Vancouver Island in forest clearings and alpine slopes with a southern exposure. Burrows, dug between rocks, provide protection from predators.
Length: Body: 300 to 600 mm Tail: 100 to 250 mm.
Weight: From 3-7.5 kg.
Adaptations: They have a "pecking order" lead by adult males. Marmots are true hibernators - for 6 months the entire family of 15 or so animals huddle together. When outside temperatures drop below freezing, their body temperature can drop to 4.5 - 7.5C. Every 3-4 weeks they awaken to defecate and urinate
Reproduction: Most animals do not breed until their fourth summer.
Litters of up to 3 young are born after a gestation period estimated at 30 days.
They may reproduce only every second year.
Wild Diet: Vancouver Island marmots are herbivores, feeding on more than 50 plant species. During the spring they feed on berries, roots, bark, and on grasses and early-blooming flowers. During the summer they eat flowers, berries, grasses and leaves
Zoo Diet: A variety of leafy green vegetables, including romaine lettuce, dandelion greens and kale, as well as cobs of corn, yams, and other vegetables.
Status: CRITICALLY ENDANGERED. Their rapid decline may be due to forestry, which has concentrated them in small areas, making them more vulnerable to predators, disease, and changes in climate and vegetation.
