This dataset is a collection of measurements which make up two water quality indexes: Nutrients, Physical and Major Ions (NPMI) Index and Metals Index. The measurements are taken at two different locations along the Hornaday River annually in early-July. Project Rationale: Water quality is a...

This dataset is a count of Lemming nests in Tuktut Nogait National Park. The counts are done annually in mid-July at 12 predetermined sample locations 1 ha in size. Lemmings are an important herbivore and source of food for predators. Lemming populations often fluctuate dramatically, typically...

Monitoring contaminants in gull and tern eggs is a useful tool for gaining insights into local environmental conditions because gulls and terns are integrators of processes occurring at lower levels in the food web and their eggs are generally formed using local food sources. Therefore, the...

The Peace-Athabasca Delta (PAD) is a huge wetland complex which provides important habitat for wildlife and migrating waterfowl. Remote sensing provides a way to monitor this large and remote area. A combination of optical and radar (Radarsat) satellite imagery is used along with ground truthing...

This measure is based on muskrat aerial surveys in the Peace-Athabasca Delta (PAD), done in collaboration with local indigenous groups. Muskrats are a keystone species. They play a pivotal role in the food web of the PAD and as such are a good indicator of what is going on at higher trophic...

The Peace Athabasca Delta (PAD) is a dynamic deltaic ecosystem that is driven by natural, periodic floods. Vegetation communities naturally vary with floods and droughts, but changes in the long term can be detected. Specific concerns include: a shift away from aquatic communities, encroachment...

Monitoring the abundance diversity and distribution of birds in wetlands is used to track the effect of changes in hydrology and water quality related to human activities, flow regulation and climate change. Automated Recording Units (ARU) are deployed annually in the spring prior to the...

Snowshoe hare are a keystone species of the boreal forest with a 9-10 year population cycle. Hare densities are positively correlated with other species and can have significant impacts on vegetation during portions of their cycle, and may affect plant survival and composition on a local level....

The Wood Buffalo National Park (WBNP) Bison Abundance database is a data set that documents numbers of bison observed during bison population estimate surveys conducted in WBNP. Survey methodology was standardized from 2002 to present. A strip transect survey allows for both minimum counts and a...

This bird monitoring program uses both traditional point counts and audio recordings to detect changes and trends in the relative abundance and community composition of a suite of forest bird species within Nahanni National Park Reserve. The intent of this study is to provide an early warning of...

Vegetation determines primary productivity as well as the diversity and types of habitat available to wildlife species. Alpine vegetation is sensitive to environmental and ecological changes. Park staff measure vascular plant diversity and the relative abundance of major plant life-forms in...

Forest ecosystems are a vital component of Nahanni National Park Reserve, covering approximately 80% of the park. Forest vegetation condition is currently a composite of three sub-measures: changes in (1) mature spruce stand growth rates, (2) mature spruce stand mortality rates, and (3)...

Monitoring pika occupancy and persistence over time will help to assess the impacts of climate change and the ecological integrity of Alpine Tundra ecosystems within Nahanni National Park Reserve. Annual visual counts of active hay piles by foot as well as auditory surveys are used to assess pika...

Remote sensing is used to monitor changes to the fire regime - including area burned and fire frequency; this is on an ongoing measure.

Caribou are a culturally important species to the Dene people, and traditional harvest is permitted in the national park reserve. The park monitors sustainability of the caribou populations by carrying out aerial surveys.

This measure will track impacts associated with recreational use and natural changes that occur on the Fundy National Park trail system. Each trail is evaluated according to a qualitative trail condition rating system. A park-wide footprint assessment for the entire trail network will also be...

Invasive alien plants (such as Japanese knotweed, woodland angelica) are considered a serious problem for many protected areas. Fundy National Park reports on the presence of priority invasive species in grid cells; the grid overlays the entire national park.

At high densities, moose can do extensive damage to forests by over browsing - altering forest composition and forest succession. One moose may consume 30 kg of vegetation per day. Fundy National Park conducts aerial censuses of the moose population every 5 years.

Monitoring of the tree landscape permits detecting changes in habitat availability, forest productivity, forest health, and other ecosystem functions. The park uses permanent sample plots to monitor tree health, growth rate, and forest succession; remote sensing is used for landscape-scale...

This dataset includes annual average Julian dates of spring green-up, fall brown-down, and plant productivity from 2000-2010. The data are from remote sensing. The MODIS (Moderate-resolution Imaging Spectroradiometer) satellite provides an image of the park every 10 days, which is used to...
