The Elk Island National Park monitors the lake water quality annually in two lakes by measuring parameters such as: nutrients, heavy metals, major ions, physical characteristics, and pollutants/contaminants.

Elk Island National Park measures beaver abundance and distribution every three years in the fall using aerial surveys to count beaver food caches.

Elk Island National Park annually conducts an aerial census of bison populations of the entire park, as well as opportunistically surveying herd composition. Bison population data is in the same database as elk and moose populations.

The Elk Island National Park annually monitors the change in amphibian occupancy by using call counts, including data collected by citizen scientists.

Elk Island National Park conducts an ungulate aerial surveys of the entire park, to census the elk and moose populations. The surveys are carried out in the late fall or winter annually. Park staff also conducts opportunistic counts of elk and moose over the summer and obtain demographic...

Sensitivity analyses indicate that a small drop in black bear survival rates greatly increases the risk of extinction in both females and males. Since the mortality rate of bears in the park is directly affected by harvesting intensity and habitat alteration, La Mauricie National Park aims to...

The American marten (Martes americana), fisher (Martes pennanti) and Canada lynx (Lynx canadensis) are predators that have a prominent place in the food chain of the forests in La Mauricie National Park. They are sensitive to large-scale anthropogenic pressures that can occur in the region and...

Intensive tree cutting and certain silvicultural practices carried out around La Mauricie National Park have fragmented moose forest habitat. In addition, the eastern wolf plays a key role in moose population dynamics in the park. In view of the forest habitat disturbances, sometimes harsh...

The effects of climate warming, eutrophication, air pollutant inputs and forestry activity that occurred before La Mauricie National Park was created influenced and continue to influence today water quality in the park. These stress factors threaten the natural evolution of aquatic ecosystems....

The number of common loons and their breeding range have decreased significantly since the beginning of the century. There is concern about the number of breeding pairs and the number of fledglings. In order to determine what the population status is throughout La Mauricie National Park, loons...

Frogs, like all other amphibians, are declining all around the world, in both pristine and protected areas as well as suburban marshes bordered by highways. This decline is due to the combined effects of a number of factors, such as an increase in ultraviolet rays, chemical pollution, habitat...

Yoho National Park monitors invasive alien plants with the use of permanent, random stratified, transects established in each of the three management zones, in close proximity to vectors of spread (highways, trails, campgrounds, etc.). Percent cover of all detected non-native species is recorded...

Yoho National Park monitors invasive alien plants with the use of permanent, random stratified, belt transects established in the alpine. Occurrence frequency of all detected non-native species is recorded along a belt transect.

Vehicle-caused wildlife mortality and wildlife management destruction data for Yoho National Park between the years 2005 and 2017. Each species mortality is recorded by date, location, count, age, gender, and cause. For more recent records please refer to “Human-wildlife coexistence incidents in...

The Yoho National Park measures the condition of lake fish communities by the level of deviation of current fish presence in a lake from historic, pre-stocking fish presence.

Olive-sided Flycatcher observations from incidental observations and mortality data reported in Yoho National Park between 1981- 2017. Each observation is recorded by date, location and number of individuals observed.

The Area Burned Condition Class (ABCC) measure is based closely on the fire cycle concept and assesses the degree of departure from historic or reference area burned levels within a park. ABCC provides an indication on the state of fire as an ecological process. ABCC was developed as a medium to...

Whitebark pine blister rust (Cronartium ribicola) is an introduced pathogen affecting whitebark pine (Pinus albicaulis) and limber pine (Pinus flexilis). Whitebark pine is an endangered species protected under the Federal Species at Risk Act (SARA) and Limber pine is designated as an endangered...

A water quality monitoring station on the Yoho River at Yoho Crossing (and Kicking Horse River station near Field) are operated by Environment Canada in partnership with Parks Canada. The Canadian Council of Minister’s metric of Water Quality Index (WQI) is a unitless value between 0 and 100....

American Badger (jeffersonii subspecies) observations from remote wildlife cameras and incidental observations reported in Yoho National Park between 2004. Each observation is recorded by date, location, and number of individuals observed.
