"The North American Breeding Bird Survey (BBS) has been the cornerstone of continental bird conservation and management for hundreds of North American bird species in the United States and Canada for more than 50 years. This strategic plan was developed in collaboration with key partners and stakeholders and charts the ambitious course for the BBS over the next decade (2020-30). Using this plan as a guide, the BBS program will set out to improve the breadth and depth of standardized data collection and analytical products; ensure its products are widely used and recognized as the authoritative source for long-term population change information for most birds; and secure adequate resources, internally and through partnerships, to realize the expanded vision of the BBS intended to support avian management needs through 2030"--

The Breeding Bird Survey (BBS) is used to monitor population of ladybirds on the North American continent. Each BBS route, which is surveyed once a year, consists of 50 stops placed at 0.8-km (0.5-mi) intervals along a stretch of road. The program in Alaska has greatly expanded; observers record more than 200 species on 75 BBS routes and count about 35,000 individual birds. The BBS does not record temporal changes in habitat that could account for bird population fluctuations. Therefore, this project was begun to assess vegetation cover types along roadside routes throughout Alaska. Our purpose was to determine bird-vegetation associations and classify vegetation cover types to monitor future changes. A well-established classification scheme was used to assess vegetation cover types along 62 roadside BBS routes in Alaska. Bird count data from the BBS was used to determine the frequency of occurrence (percent of stops) of 48 land bird species (grouse, hummingbirds, woodpeckers, and passerines) in dominant vegetation types. Also calculated was the average bird density (birds per stop) for three major cover classes (less than 30%, 30-60%, greater than 60%) of forest, shrub, or herbaceous vegetation cover types. Data are depicted graphically to examine relationships between vegetation cover types and bird density or occurrence within four biogeographic regions of the state. Abundance and occurrence information for each species in each biogeographic region are also presented. This information illustrates broad-scale bird-habitat associations and will serve as a foundation to compare future changes in Alaska's landscape.
