Found 10 records similar to Beaver Abundance - Riding Mountain
Elk Island National Park measures beaver abundance and distribution every three years in the fall using aerial surveys to count beaver food caches.
Moose in Riding Mountain National Park are affected by hunting, predator population numbers, winter severity, and disease. Riding Mountain National Park conducts annual aerial surveys to monitor the moose population to determine if the population is within the established population thresholds based on historic estimates.
The wolf population in Riding Mountain National Park is monitored through track counts that are conducted each winter according to methods established by Canadian Wildlife Service in the 1970’s. Wolves are the top predator in Riding Mountain National Park and monitoring their numbers assists in determining their long-term sustainability in the park.
The park employs aerial surveys to map active beaver lodges/dams in Terra Nova. A selection of sites are ground-thruthed on foot or by canoe.
This dataset focuses on monitoring beaver colonies in Forillon National Park. Beavers have a major influence on aquatic ecosystems in the park. Monitoring fluctuations in this population can help us better understand variations in the physicochemical characteristics of watercourses and possibly in other aquatic populations in the park. Beaver colony data are collected primarily as part of a park-wide aerial survey by helicopter.
Beavers are important ecosystem architects, creating wetland habitats, thickets and meadows by damming streams and cutting down woody vegetation along stream banks. This measure consist of an aerial survey of the number of active beaver colonies in lowland forests of Gros Morne National Park. It is conducted every fifth year in the Fall.
Elk abundance and population composition are assessed annually during an aerial survey conducted between mid-January and mid-February. The elk population composition is measured annually in a classified aerial count held in late Fall.
The beaver (Castor canadensis) is a large, primarily nocturnal semi-aquatic rodent used as an indicator of the conditions in freshwater ecosystems due to its role as a keystone species and an ecosystem engineer. The potential for beaver colonization within Kouchibouguac National Park is considerable due to the quantity of first and second order streams within its borders. In addition, the most important and preferred food source available to beavers in the Park is the trembling aspen (Populous tremuloides); though this tree species colonizes disturbed areas and is usually replaced by conifers or shade-tolerant hardwoods in long-term succession. Hence, the population dynamics of beavers can reflect large-scale changes in forest ecosystems.
Beavers were formerly extirpated from the Bruce Peninsula, but have re-colonized the area after a two century absence, making significant changes to the park landscape. Bruce Peninsula National Park monitors active lodges by counting food caches during helicopter surveys in the fall, just before the freeze-up.
The integrity of fire-dependent forest types will be maintained through prescribed burns. The park's fire management program uses remote sensing to monitor post-burn changes on the landscape annually. The Area Burned Condition Class measures will be used as per the PCA Fire Monitoring Plan.
