![]() ![]() Researchers recorded the animals’ weight, age, and sex and then fitted them with small radio transmitter collars. ![]() More than 100 marten, including adults, juveniles, males and females, were captured using baited live traps. Each study site was several thousand square kilometres in size, and contained both managed and unmanaged forests. The research was conducted in two locations in Northern Ontario, near Red Lake and Kapuskasing and concluded in 2007. American marten ( Martes americana americana)Ī large-scale collaborative field study was initiated in 2000 by the Canadian Forest Service, the Ontario Ministry of Natural Resources and the University of Guelph to gather scientific data about marten populations in managed and unmanaged forests. This work will enable land managers to make informed decisions that consider the needs of marten habitat. The effects of changes in forest tree species composition are also of concern.Ĭanadian Forest Service researchers are studying marten in Newfoundland and Ontario to understand how they respond to forest management practices. Research indicates that intensive silviculture likely decreases desired habitat characteristics for marten in the short-term, because it reduces coarse woody debris and standing dead wood, habitat features important to marten. We know that they avoid young stands in boreal forests, generally preferring mature and older conifers and mixedwoods. Gaps exist in what we know about the long-term effects of forestry activities on wildlife species such as marten, which are often used as indicators of forest ecosystem integrity. In 2007, Newfoundland marten were reclassified from endangered to threatened under the federal Species at Risk Act and the provincial Endangered Species Act. Marten has traditionally been prized by trappers for its high-value fur, sometimes referred to as Canadian sable.Ī sub-species of the American marten, the Newfoundland marten ( Martes americana atrata), can only be found on the island of Newfoundland and on the Labrador peninsula. The American marten ( Martes americana), also referred to as the pine marten, is a shy weasel-like mammal found throughout Canada in coniferous and mixedwood forests.
