Description:
Abstract:
The project utilized data from the Waterfowl Breeding Population and Habitat Survey, which is an annual survey conducted since 1955 by the governments of the United States and Canada to monitor waterfowl populations. These survey data were spatially and temporally layered onto long-term databases of fire perimeters for Alaska and western Canada, providing a record of waterfowl transects which had burned over the last 60 years. The project modelled abundance of dabbler and diver pairs in relation to time since fire, looking at short-term (e.g., 1–3 years) versus long-term timeframes (e.g., >5 years), and in relation to fire extent, defined as the percent of transect which had burned.
Purpose:
The aim of the study was a long-term examination of the effects of wildfires in the boreal forest of western North American on abundance of breeding waterfowl populations.

General_Taxonomic_Coverage:
In this dataset, duck species are grouped into two categories: dabblers and divers. Dabblers are made up of the following five species observed on the surveys: Green-winged Teal (Anas crecca), Mallard (Anas platyrhynchos), Northern Pintail (Anas acuta), Northern Shoveler (Anas clypeata). Divers are made up of the following seven species observed on the surveys: Bufflehead (Bucephala albeola), Canvasback (Aythya valisineria), Goldeneye (Bucephala clangula & B. islandica), Merganser (Mergus merganser & M. serrator), Ring-necked Duck (Aythya collaris), Scaup (Aythya affinis & A. marila), Scoter (Melanitta fusca & M. perspicillata). Goldeneye, mergansers, scaup, and scoters cannot be differentiated to individual species during the survey. Thus, counts are lumped together for those species.

The Canadian National Fire Database (CNFDB) is a collection of forest fire data from various sources; these data include fire locations (point data) and fire perimeters (polygon data) as provided by Canadian fire management agencies (provinces, territories, and Parks Canada). Fires of all sizes are included in the database, but only those greater than 200 hectares in final size are shown in the map above — these represent a small percentage of all fires but account for most of the area burned (usually more than 97%).
The Canada National Fire database was used to include perimeters of fires that overlapped each western boreal Waterfowl Breeding and Population Habitat Survey segment.
Process_Step:
Process_Description:
We obtained mapped perimeters of fires from the Alaska Large Fire database and the Canadian National Fire Database. The Alaska database contains records of fire perimeters for most large fires (>400 ha) since 1942 and all fires >40 ha since 1987, while the Canadian database contains records of fire perimeters from the 1940s to present and is principally comprised of fires ≥200 ha. We limited our use of Waterfowl Breeding Population and Habitat Survey data to those collected in the western boreal forest, basing our boundary on the North American boreal zone map of Brandt (2009) and extending from Manitoba in the east to Alaska in the west. Next, using a geographic information system, we extracted each western boreal Waterfowl Breeding Population and Habitat Survey segment that spatially and temporally overlapped fires, producing a final database of 554 segments. Collectively, these 554 segments comprised 60% of all western boreal segments and were situated in 27 strata, totaling 628,950 ha of annually surveyed landscape. We temporally organized our Waterfowl Breeding Population and Habitat Survey database for each transect segment on the basis of years before and after wildfire, producing a continuous time since fire variable. For example, a segment burned in 2002 was coded as follows: 2001 = 1 year pre-fire, 2002 = year 0, 2003 = 1 year post-fire, 2004 = 2 years post-fire, etc. We did not consider any fires that occurred >5 years before each transect segment’s inaugural survey, which was typically 1955. For segments with >1 fire, we reset time since fire to 0 upon occurrence of the subsequent fire if it occurred >5 years after the previous fire, irrespective of burn extent, or if it had equal or higher burn extent, irrespective of time between fires. Next, we assigned each post-fire year a burn extent score based on percent spatial overlap between the Waterfowl Breeding Population and Habitat Survey transect segment and the fire perimeter, where 1–20% overlap was small, 21–60% medium, and >60% large. This covariate accounts for spatial heterogeneity of fire impacts to Waterfowl Breeding Population and Habitat Survey transects in the absence of burn intensity data.

Attribute_Definition:
The unique identifier of each site used in our study. The site contains three numbers, each separated by a period, that refer to the stratum, transect, and segment number of the Waterfowl Breeding Population and Habitat Survey (https://migbirdapps.fws.gov/mbdc/databases/mas/maydb.asp?opt=maydb). For example, a site id of 15.1.4 means that the data comes from stratum 15, transect 1, segment 4 of the Waterfowl Breeding Population and Habitat Survey. The data follow a spatial hierarchy, with stratums being large spatial units that contain numerous transects, while transects are subdivided into segments. Sites are permanently-located and are thus surveyed each year. In the following descriptors of data fields, each reference to ‘Site’ will refer to the definition provided here.
