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 year period, of Atlantic salmon returning to spawn in three rivers in Gros Morne - Western Brook, Trout River and Deer...

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 estimated using the Gasaway (1986) stratified random block method. Bull, cow, calf and unknown Moose are counted in...

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

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 perimeter of 14 late snowbeds, which allows measurement of the meltout date for that point in each snowbed each year.

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 temperature regime, reports on flow parameters in 10-12 park streams over time - using in-situ water level data loggers,...

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

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, and Chlorophyll A. These metrics are compiled into a water quality index (WQI) that summarizes overall water quality.

Plant community structure is measured at 16 sites within the park on a four-year schedule. A series of five 2x2 metre quadrats are completed at each site with percent cover of all ground vegetation recorded.

The park is developing a protocol to monitor the extent of eelgrass beds through remote sensing.

Terra Nova National Park employs a kicknet sampling procedure to monitor the species richness and relative species abundance of stream invertebrates. Streams chosen for sampling are randomly selected within second order watersheds.
