Alaska Landbird Monitoring Survey (ALMS) Population Trend Estimates

This data release provides Alaska breeding landbirds population estimates from three hierarchical Bayesian population trend models, following the methods of Handel and Sauer (2017) and Amundson et al. (2014). The three models are: (1) ALMS only - uses point-count data from the Alaska Landbird Monitoring Survey (ALMS) off-road points counts in Bird Conservation Regions (BCR) 4 (Northwestern Interior Forest) and 5 (Northern Pacific Rainforest), (2) BBS only - uses the North American Breeding Bird Survey (BBS) road-based, and (3) and Joint - uses data from both surveys. BCRs are defined according to the North American Bird Conservation Initiative (https://nabci-us.org/).
