Terra Nova National Park censuses tern nests on 23 small islands in Newman Sound, to monitor species productivity and population dynamics.

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 found. Rock Ptarmigan are the only species of bird that live year round in the Alpine tundra of Gros Morne. This measure...

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 from spring to fall using temperature loggers. The water temperature is recorded hourly and these data used to assess the...

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...

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,...

Terra Nova National Park conducts weekly shorebird surveys during August and early September in order to monitor the abundance of Greater Yellowlegs and other shorebird species.

Terra Nova National Park monitors crab populations for the presence of the invasive European Green Crab; the abundance of native Rock Crab is also monitored. Park personnel uses baited traps for these surveys.

Terra Nova National Park uses fixed station stream gauges and pressure temperature loggers to monitor the following stream flow aspects: Richards-Baker index of flashiness, ratio of yearly precipitation to runoff, low flow volume, annual maxima/minima, and mean monthly flow.
