Broad Ecosystem Unit (BEU) and forest cover at the 1:250,000 scale had been mapped to contribute information to the Central Coast Land and Coastal Resource Management Plan. We ranked BEU and forest cover polygons based on their suitability for marbled murrelet nesting habitat. During the 1998 breeding season, we conducted a reconnaissance level survey of 27 selected watersheds draining into the central Coast. We used high-frequency radar to count marbled murrelets as they entered the watersheds before dawn. Geographic information system (GIS) mapping enabled us to readily calculate both the size of the watersheds and the amount of suitable nesting habitat available (based on both the broad ecosystem and forest cover information). Based on the radar counts we calculated an index of the number of nesting marbled murrelets per hectare of suitable habitat. This index was used to rank the suitability of the watersheds for marbled murrelets and delineate broad areas to be further examined...
