The Canadian Precipitation Analysis System (CaPA) produces a best estimate of 6 and 24 hour precipitation amounts. This objective estimate integrates data from in situ precipitation gauge measurements, radar QPEs and a trial field generated by a numerical weather prediction system. In order to...

The atlas provides printable maps, Web Services and downloadable data files representing seabirds at-sea densities in eastern Canada. The information provided on the open data web site can be used to identify areas where seabirds at sea are found in eastern Canada. However, low survey effort or...

The Water Survey of Canada (WSC) is the national authority responsible for the collection, interpretation and dissemination of standardized water resource data and information in Canada. In partnership with the provinces, territories and other agencies, WSC operates over 2800 active hydrometric...

This polygon outlines the basic area included in the survey counts. This area is the best approximation of the mudflat that can be surveyed from shore and is exposed at tide tide height of 3.5 m, based on tidal predictions at Point Atkinson, British Columbia.

This line outlines the basic survey route included in the survey counts. This route is the best access to areas that can be surveyed from shore.

Survey effort is a polygon feature class with the original transects – for reference.

Rare species is a point feature class containing rare species sightings.

Study area is a polygon feature class showing the extent of where most of the bird sightings were recorded and then used in the atlas. A few rare species have been included as well that go beyond this area.

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...

Grids surveyed is a polygon feature class containing the 5’ latitude by 5’ longitude grid cells surveyed for all seasons combined including the grids that were surveyed but where no species were seen. In order to produce maps for a specific season a selection for these grids must be performed.

Average grid cell density is a polygon feature class containing the average density value for each grid cell per species/groups and season.

Sidney Island Shorebirds Survey transects line feature.

Survey areas is a polygon feature class containing mudflats and staging areas observed for shorebirds.

Survey transects is a line feature class containing transects completed in 2011.

This spatial file includes the polygon boundaries of the four Pacific Great Blue Heron Conservation Regions in British Columbia, as described in the management plan. These Conservation Regions are recognized based on degree of isolation, population sizes, and differences in trends and threats....

This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy is defined as...

Survey points is a point feature class containing transects and observations completed in 2011.

This file includes the spatial boundaries for the Pacific Great Blue Heron Potential Area of Occupancy for its entire Canadian range. The Potential Area of Occupancy is a simple model that highlights the heron's preferred forest habitat at a high level. Potential Area of Occupancy...

The Government of Canada is committed to the long-term sustainability of Canada's lakes and waterways to ensure that there is clean water for all Canadians, both for this, and future, generations. To this end, on August 2nd, 2012, Prime Minister Stephen Harper announced the launch of Phase II of...
