The park monitors water quality of streams and ponds (lakes) on a triennial cycle, reporting on total organic carbon, acidity, phosphorus, nitrogen, dissolved oxygen, turbidity,...

The park correlates pitcher plant morpology with availability of atmospheric nitrogen, as the latter may affect pitcher-plant development.

Stream hydrology strongly affects habitat quality for most stream-dwelling species, and is affected by both climate and land use. This measure, which is colocated with stream...

Late snowbeds afford critical habitat for many species of Arctic and alpine plants in Gros Morne National Park. Temperature loggers are being anchored at ground level within the...

Terra Nova National Park monitors non-native mammal browse pressure on forest plant communities on transects and plots.

Introduced Moose, lacking natural predators in Gros Morne, are causing widespread damage in park forests. Park-wide Moose density will be monitored using aerial surveys and...

Atlantic salmon are an ecologically and culturally important species in healthy aquatic systems of western Newfoundland. This measure determines the status and trend, over a 10...

Stream thermal regime has important consequences for aquatic organisms, and is sensitive to climate and land use. The Park is monitoring thermal regimes at 10 sites annually...

The Island of Newfoundland is home to the most southerly population of Rock Ptarmigan in North America and is the only place where the subspecies Lagopus mutus welchi can be...

Intensive moose browsing appears to have led to a large reduction in woody plant abundance and diversity in Gros Morne National Park mature forests.This measure assess the...

Beavers are important ecosystem architects, creating wetland habitats, thickets and meadows by damming streams and cutting down woody vegetation along stream banks. This measure...

Birds are an important component of the biodiversity of boreal forests and bird populations can serve as a useful measure of forest health. The monitoring of winter forest bird...

Overbrowsing of balsam fir saplings by introduced moose can lead to stand conversion to non-forest. The park measures the browse rates of fir saplings in mature forest stands,...

Herb willow is dominant Arctic-alpine plant in snowbeds and, being a low-growing species, could potentially be crowded out if southern species colonise these sites. Herb willow...

In eastern Canada, Harlequin ducks are uncommon and are listed by COSEWIC as a species of special concern. Resident of fast flowing-rivers and streams during the breeding...

On insular Newfoundland, the Arctic Hare reaches the southernmost limit of their distribution and are typically found in mountainous areas where elevation and climate have...

Plethodontid salamanders are ‘early warning’ indicators of biodiversity and forest conditions due to the high densities of populations in addition to the keystone role of this...

The Acadian forest in a natural state is one of the richest and more diverse temperate forests in the World, however it has been listed as one of six endangered forests in North...

Peatlands are valuable ecosystems due to their critical ecological functions, however these sensitive habitats are vulnerable to various anthropogenic (e.g., peat-moss...

River otters (Lontra canadensis) are semi-aquatic mammalian predators closely associated to freshwater resources but also linked to terrestrial habitat features, at the aquatic-...
