Found 10 records similar to Tern Abundance - Terra Nova
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.
The second largest concentration of common terns (Sterna hirundo) in North America is found on Tern Islands, a set of three small barrier islands separated by water at high tide located within Kouchibouguac National Park. These seabirds are indicators for the condition of coastal, marine, as well as estuarine ecosystems due to the use of these nesting and/or breeding grounds, and their reliance on the distribution of small fish populations in lagoons or along the outer beaches of barrier islands throughout the breeding season. The purpose of the common tern colony monitoring program is to determine the annual total number of nests and estimate mean clutch size in order to evaluate long-term breeding population health. The methods for this measure involve an annual systematic census on Tern Islands over a 1-2 day period in mid-to late June during the late incubation stage.
Monitoring of the number of eggs and nests for the tern. Field data from 1992 to 2019. Many islands in the MANPRC are used by the terns for their nesting. The presence and great abundance of this species are characteristic of the inland ecology of the park.
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.
The park maps the existing human footprint and footprint edge in Terra Nova.
Terra Nova National Park monitors annual decay rate by measuring decomposition of tongue depressors buried within randomly selected Balsam Fir and Black Spruce plots.
Terra Nova National Park employs fixed station pressure/temperature loggers to continuously monitor stream water temperatures over the entire summer at designated stream study sites.
Terra Nova National Park monitors non-native mammal browse pressure on forest plant communities on transects and plots.
Terra Nova National Park monitors wetland plant richness at 30 randomly selected plots along a 80 meter transect.
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.
