Landbird inventory in San Juan Island National Historical Park, 2002. The Institute for Bird Populations (IBP) collaborated with personnel at San Juan Island National Historical Park to initiate a Park-wide inventory of landbirds. The goals of the inventory were to estimate habitat-specific density and park-wide abundance for a large suite of species, and to produce information that will assist park managers and cooperators in designing the park's long-term landbird monitoring program. The objective of this inventory is therefore to determine habitat-specific density of landbirds during the breeding season at San Juan Island NHP, using methods consistent with those employed in other parks across the North Coast Cascades Network. These results may serve as baseline data for monitoring future ecological changes within the park. We recorded 1,728 individual bird detections during 113 point counts throughout the park—77 at American Camp and 36 at English Camp. Four habitats - Douglas-fir, Mixed Conifer, Shrub, and Grassland - were relatively well represented, while the other habitats included no more than five points each. Results, particularly species lists, for the poorly sampled habitats should merely be considered anecdotal.
