    The national wetland layer contains wetland data compiled from the best available data from each region, classified by wetland type. Wetlands are mapped as polygons in geographic layers, which are integrated into a master geodatabase at the national scale.Information from each contributing dataset was classified based on the Canadian Wetland Classification System, which contains five main wetland classes (Bog, Fen, Marsh, Swamp, and Shallow Water) that represent the types of wetlands encountered in Canada. An additional category, “partially classified” was used to preserve boundary information for wetlands that could not be classified into the main categories with existing information.

    Environment and Climate Change Canada’s cause-effect monitoring is focused on understanding how boreal songbirds, including several Species at Risk, are affected by human activity in the oil sands area, particularly the impact of the physical disturbance of forested habitats from exploration, development and construction of oil sands. Determining the abundance of songbird species associated with various habitat type(s) and understanding how the type and number of birds varies with type and amount of habitat, are important components of assessing the effect of habitat disturbance. Regional-scale monitoring focuses on understanding how and why boreal songbirds, including several Species at Risk, are affected by human activity across the Peace, Athabasca and Cold Lake oil sands area. Local-scale projects focus on addressing gaps in our understanding of complex response patterns at regional scales by targeting specific habitats or development features of interest. These data contribute to: a. improving the design of monitoring programs; b. explaining observed trends in populations (why bird populations are increasing or decreasing); c. predicting population sizes within the oil sands area; and d. assessing the individual, additive and cumulative effects of oil sands and other resource development on boreal birds. Data are used by ECCC and our partners to develop new models and increase the robustness of existing models of bird responses to habitat and disturbance. Because models can be used to predict outcomes of future land management scenarios, these models can assist decision-making by helping evaluate land-use choices before impacts are directly observed.

    The Stanley Park Winter Waterbird Survey, 1995-2019, was made possible through a co-operative effort between Environment and Climate Change Canada, the British Columbia Institute of Technology’s Wildlife and Recreation Program, and the Stanley Park Ecology Society. The intent of the survey is to collect data to estimate the presence, abundance, and distribution of waterbirds along the Stanley Park foreshore in Vancouver, British Columbia, Canada. This dataset is a compilation of species-level occurrence, abundance and distribution data of marine birds collected systematically for the last 23 years (1995-2019) on roughly a weekly basis between September and April each year along the Stanley Park seawall. This long-term dataset of marine birds, has a high value for analysing spatiotemporal trends in marine bird species.

    The Atlas of Pelagic Seabirds off the West Coast of Canada presents maps that display the distribution of 48 species of seabirds and two species pairs (i.e., Red-necked and Red Phalaropes, and Hawaiian and Galapagos Petrels). Seabird surveys were conducted aboard commercial and Canadian federal government ‘ships-of-opportunity’ from 1982-1983 and 1991-2005 within the study area (45° N to 58° N and from the coast to 148° W). Sightings of rare species that came from other sources (including some pre 1982 and post 2005) are also included in order to present as complete a picture as possible. For 33 species and one species pair, the average densities within 5’ latitude by 5’ longitude grid cells are displayed seasonally. The seabirds mapped in this manner include 11 species of Procellariiformes (albatrosses, fulmars, petrels, shearwaters and storm-petrels), and 24 species of Charadriiformes (phalaropes, skuas, gulls, terns and auks). The sighting locations for an additional 15 species and one species pair are also mapped. This group, comprised of 10 species of Procellariiformes and seven species of Charadriiformes includes species that are relatively uncommon to rare in the study area (but previously documented); and species that are extremely rare and/or have not been documented and thus remain unconfirmed. These data may be used to generate presence/absence and trends in and estimates of relative abundance. These data can also be used to examine patterns in temporal and spatial distribution. However, due to the opportunistic nature of the surveys, both in space and time, these data should not be used to determine absolute abundance. The rationale for developing this atlas was the recognized need for a product that could assist with: coastal zone and conservation area planning; emergency response to environmental emergencies; and identification of areas of potential interactions between seabirds and anthropogenic activities. In addition, the data used to develop the document provides a baseline to compare with future seabird distributions in order to measure the impacts of shifts in composition, abundance and/or distribution of prey, and climatic and oceanographic changes.

    The Canadian Breeding Bird Census (BBC) Database contains data for 928 breeding bird plot censuses representing all known censuses of breeding birds carried out in Canada during the period 1929–1993. The 928 records in the database represent 640 unique census plots located in all provinces and territories, except Prince Edward Island. The BBC, which was replaced by the current Breeding Bird Survey, is one of the longest-running surveys of bird populations in North America, and was designed to help determine abundance and distribution patterns of bird species. An important feature of the BBC Database is the habitat data associated with each census plot. The most prevalent vegetation species in different layers (canopy, shrub and ground cover) were recorded to reflect the assumption that birds respond principally to vegetative structure.
