Herring gull (Larus arentatus, HERG), great blue heron (Ardea Herodias GBHE), double-crested cormorant (Phalacrocorax auritus, DCCO) and ring-billed gull (Larus delawarensis, RBGU) have been monitored in Pukaskwa National Park since 1977 as part of the colonial waterbird monitoring program. A complete count of active nests on islands found along the ~120km of coast of Pukaskwa is conducted based on the Canadian Wildlife Service (CWS) protocol. The nest count is carried out during the peak of breeding over a period of 2-3 weeks. From 1977 – 1981, surveys were conducted annually and used an island numbering system (Old Colony Number in datasheet).
These fish-eating colonial waterbirds breed and nest in colonies on islands in and around Fathom Five National Marine Park. Five species of colonial waterbird are monitored. These birds and their eggs are effective measures of environmental contamination and aquatic ecosystem health.
Data Sources: Banque informatisée des oiseaux de mer au Québec (BIOMQ: ECCC-CWS Quebec Region) Atlantic Colonial Waterbird Database (ACWD: ECCC-CWS Atlantic Region).. Both the BIOMQ and ACWD contain records of individual colony counts, by species, for known colonies located in Eastern Canada. Although some colonies are censused annually, most are visited much less frequently. Methods used to derive colony population estimates vary markedly among colonies and among species.
Historically, Pukaskwa had two naturally occurring populations of Pitcher’s Thistle; Creek Beach and Crescent beach, both located in Oiseau Bay. On Sept. 22 & 23, 1985 there was a severe windstorm that severely affected the beach at Oiseau Bay and caused erosion at the colony site and then on June 26, 1986, there was a severe thunderstorm with heavy rain that caused the washout of a huge portion of the Crescent Beach colony. Both of the colonies have shown negative population trends to the point where the Crescent Beach colony is now considered extirpated. From 1982 to 2014, each location was divided into plots and within each plot, each plant was tagged with a unique identifier using dymo tape and a bicycle spoke.
Data on the production and value of honey, beekeepers and colonies.
Areal Extent (hectares) of black-tailed prairie dog colonies in the Park monitored through colony perimeter mapping every 2 years. This is actively managed to increase prairie dog population through a combination of plague mitigation (i.e. dusting and sylvatic plague vaccine baits) and habitat enhancement/colony expansion (i.e. mowing edges, fire and grazing regimes) and upon feasibility and risk assessment, population expansion (i.e.
The Grasslands National Park monitors the area of occurrence of the Black-Tailed Prairie Dog through measuring surface area in hectares of active colonies. Monitoring provides data on the expansion or contraction of black-tailed prairie dog colonies in the park. Active colony areas outside of the park and in the greater park ecosystem (southwest Saskatchewan) are also monitored, but this data is not included.
Distribution of cormorant habitat in coastal British Columbia showing relative abundance (RA) by season and overall relative importance (RI). RI is based on project region and not on the province as a whole. CRIMS is a legacy dataset of BC coastal resource data that was acquired in a systematic and synoptic manner from 1979 and was intermittently updated throughout the years. Resource information was collected in nine study areas using a peer-reviewed provincial Resource Information Standards Committee consisting of DFO Fishery Officers, First Nations, and other subject matter experts.
