Carnivore situation - Forillon

This dataset covers the status of carnivores. It is known that some carnivores, such as the American marten (Martes americana), fisher (Pekania pennanti) and Canada lynx (Lynx canadensis), are affected by forest habitat fragmentation and human presence. In addition, the American marten and fisher are often considered good indicators of forest ecosystem integrity. The Canada lynx is one of the biodiversity targets of the Northern Appalachian/Acadian conservation plan and the Forillon ecological corridor conservation plan. Given these factors, together with the knowledge acquired from studies carried out over the past 20 years, we decided to implement a long-term carnivore monitoring program based primarily on the presence of the American marten, fisher, and Canada lynx within the boundaries of Forillon National Park. This measure of the ecological monitoring program comprises three field measurements: the rate of occupancy of the American marten, fisher and Canada lynx. A total of 70 sites are sampled, 35 outside the park boundaries and 35 inside the park boundaries. The species are monitored by camera in October and November. The data are collected annually inside the park and on a five-year basis outside the park. For the American marten and fisher, the thresholds of the field measurements are based on expected rate of occupancy, as a function of the type of habitat found in the park. For the Canada lynx, thresholds are based on observed rates of occupancy taken from the literature in 2011. The assessment of this measure is carried out every five years.
