Permafrost and snow are critical to the ecology of many northern ecosystems. They influence hydrology and vegetation and can dramatically affect the quality of wildlife habitat. In recent decades permafrost temperatures in North America have increased and snowfall and spring snow cover in the Arctic have declined. These trends are predicted to continue, although with regional and seasonal variability.

Wapusk National Park is a sub-Arctic protected area covered with snow for over half of the year. Snowpack characteristics can provide important clues to impacts of climate change and park ecological integrity. Snow cover duration and characteristics affect soil and plant and animal components of the ecosystem. Current predictions for Wapusk are that with warming temperatures, snow in the Hudson Bay region will increase in amount but will stay for a shorter duration.

The map shows the location of the continuous permafrost zone and the discontinuous permafrost zone including areas of wide spread permafrost, areas of scattered permafrost and permafrost areas in the Cordillera. The map also indicates for six locations (Inuvik, Yellowknife, Thompson, Resolute, Rankin Inlet and Schefferville) the thickness of permafrost in metres and the ground temperature. Permafrost is a term used to describe the thermal condition of earth materials, such as soil and rock, when their temperature remains below 0 degrees Celsius continuously for more than 1 year. One-half of Canada's land surface is underlain by permafrost.

Wapusk National Park protects a vast landscape of coastal salt marshes, countless lakes and ponds, and a diversity of boreal-tundra interface habitats, and serves as staging areas for migrating birds, and habitat for a diversity of wildlife. Shallow lakes and ponds are created in part by thermokarst processes resulting from the melting of ground ice in areas underlain by permafrost. In northern areas, climate change brings fluctuations in temperature, permafrost and snow fall and cover which affect lake dynamics, water composition and water levels, and the plants and animals dependent on them. Lake hydrology is assessed based on hydroelocological methods developed during the International Polar Year in Vuntut National Park, and initiated in Wapusk in 2010 by the Hydroecological Team, a multidisciplinary research group from Wilfrid Laurier University and University of Waterloo led by Dr. Brent Wolfe.

Recent observations suggest that shallow lakes and ponds in the Arctic are becoming increasingly dynamic in response to climate change, and changes in water levels, lake surface area, and biological communities have been observed at several high-latitude locations. The Old Crow Flats, located 25 km north of Old Crow in the northern Yukon, is a Wetland of International Importance recognized by the Ramsar Convention. Portions of the Old Crow Flats are protected by Vuntut National Park and the Old Crow Flats Special Management Area. The Vuntut Gwitchin First Nation has observed reduced lake levels over the past few decades and are concerned about how the changing landscape may affect the ecology of the region and their traditional lifestyle.

Nunavut’s cold climate makes it a territory consisting of mostly barren land and permafrost. Permafrost is soil or rocks whose temperature remains at or below the freezing point for a long period of time. Glaciers, a mass of snow and ice that does not melt from year to year prevail in the Innuitian Mountains. Permanent sea ice occurs in the northern part of the Arctic Ocean.

Peregrine falcons are found in many regions of the northern Yukon including Vuntut National Park. These birds have the important role of top predator and are known to respond to environmental disturbances such as persistent synthetic toxic chemicals, human activity, and changes in breeding habitat, prey abundance and climate. The Canadian Species at Risk Act currently lists the anatum/tundrius subspecies of peregrine falcon as a species of special concern. Systematic surveys of peregrine falcons along the Old Crow River, including portions of VNP, began in 1975.
