The marbled murrelet (Brachyramphus marmoratus), a seabird, nests in forested stands from southeast Alaska south to Santa Cruz, California. Because of this species' close association with old-growth forests, researchers and land managers need a method to assess murrelet distribution and use patterns throughout its range. This guide describes a standardized method for surveying marbled murrelets used by researchers in California and Oregon during 1988 and 1989. Transects can be used to assess activity patterns over large blocks of land, such as States or counties. Stationary counts using an intensive inventory method can be used to survey small acreages, such as individual timber sales. In addition to bird counts, vegetation and physical data should be collected at each census point. The guide includes a form that can be used to design studies and determine activity patterns and potential use.

This report was compiled & edited by the interagency Marbled Murrelet Conservation Assessment Core Team. The 37 chapters cover both original studies & literature reviews of many aspects of the species' biology, ecology, & conservation needs. It includes new information on the forest habitat used for nesting, marine distribution, & demographic analyses; & describes past & potential effects of humans on the species habitats. Future research needs & possible management strategies for both marine & forest habitats are suggested. Charts & tables.
