The WRRB met with other members of the Conference of Management Authorities (CMA) in Fort Smith, NWT, on May 2-4, 2017 to discuss a number of wildlife species including barren-ground and boreal caribou, grizzly bears, wood bison and bats. At the meeting, the CMA reviewed the NWT Species at Risk Committee (SARC)’s 2017 assessments of the status of grizzly bear, five bat species, Porcupine and barren-ground caribou in the NWT.

In April 2017, the CMA decided to add Wood Bison to the NWT’s Species at Risk list as a Threatened species. Wood bison face a number of serious threats in the NWT, including infectious disease, habitat loss, predation and human-caused mortality. In addition, their overall population size in the NWT is quite small (an estimated 2,500 animals in total) and there is clear evidence of population decline. Read more
The CMA presented its signed consensus agreement to the Minister of Environment and Natural Resources (ENR) on April 13, 2017. The Minister is required to add wood bison to the NWT List of Species at Risk within three months of receiving the consensus agreement. Once listed as ‘threatened’, a recovery strategy must be developed for wood bison within two years.
Based on the best available traditional, community, and scientific knowledge, SARC met in April, 2017 and assessed the grizzly bear, little brown myotis and northern myotis as species of special concern in the NWT. It also assessed barren-ground caribou (Tuktoyaktuk Peninsula, Cape Bathurst, Bluenose-West, Bluenose-East, Bathurst, Beverly, Ahiak, and Qamanirjuaq herds) as threatened in the NWT.
SARC considered Porcupine caribou separately as a geographically distinct population and assessed it as not at risk in the NWT, but recommended these caribou be considered for re-assessment if there is evidence of any future declines. The Porcupine caribou herd’s range includes northern Alaska, northern Yukon and the northwest edge of the NWT.

Grizzly bears were assessed as special concern based on their small numbers, their low reproductive rates, their need for large home ranges and winter dens, and other factors, all of which make them vulnerable to the effects of threats, such as habitat loss, and less resilient.
Little brown myotis (sometimes called the little brown bat) and northern myotis (sometimes called the northern bat) were assessed as special concern because of their high vulnerability to the devastating effects of white-nose syndrome. White-nose syndrome is a fungal disease that has wiped out populations of bats elsewhere in North America, and could reach the NWT in one or two decades.
Barren-ground caribou were assessed as threatened because of dramatic population declines in most herds and multiple threats, including climate change, predation, industrial development, and forest fires. These threats and others interact with each other and add up over time to create cumulative effects which are considered unprecedented.
Before the CMA decides whether a species should be added to the NWT List of Species at Risk, each of its members will consult with the communities in its jurisdiction. The WRRB and the Tłı̨chǫ Government, for example, will meet with community members in each of the Tłı̨chǫ communities in Fall 2017 to share information and to hear people’s comments. Fact sheets have been prepared for each of the species that is being considered for listing as a species at risk. They provide information on the species, its status assessment, what’s next in the Species at Risk process, frequently asked questions and other questions to focus discussion during consultations.

A special event was also planned for CMA members –a tour of a red-sided garter snake hibernaculum (a winter den for hibernation) and a hike around a karstland loop in Wood Buffalo National Park.

Photo: karst landscape. Karst landforms are created by water sinking and circulating underground, eroding bedrock and over the course of thousands of years, leaving behind caves, natural bridges, and sinkholes. These crevices and caves provide ideal places and temperatures for hibernating Red-sided garter snakes. (Jody Pellissey, WRRB)
