Book excerpt: 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 book was released on 2008 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: We examined how oceanographic and terrestrial features influence marine habitat selection by radio-tagged marbled murrelets (Brachyramphus marmoratus), and how selection varies temporally, geographically and with respect to reproductive status. Murrelet marine habitat selection was simultaneously affected by sea surface temperature and nearshore environment characteristics, as well as distance to nest site for breeders, with lesser influence by physical oceanographic features. Marbled murrelets were generally associated with areas characterized by higher relative tidal speeds, greater depths, steeper ocean floor slopes, less freshwater inflow and proximity to sandy beaches, though the strength of these relationships varied. Breeding murrelets were also associated with proximity to nest sites. We observed within-season and between-site variability in murrelet-SST associations, suggesting that murrelets change their foraging tactics as their needs and/or local oceanographic conditions change. We suggest that availability of suitable nesting habitat within proximity of profitable marine foraging areas is critical for recovery of this species.

Download or read book Regional Population Monitoring of the Marbled Murrelet written by and published by . This book was released on 2007 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: The marbled murrelet (Brachyramphus marmoratus) ranges from Alaska to California and is listed under the Endangered Species Act as a threatened species in Washington, Oregon, and California. Marbled murrelet recovery depends, in large part, on conservation and restoration of breeding habitat on federally managed lands. A major objective of the Northwest Forest Plan (the Plan) is to conserve and restore nesting habitat that will sustain a viable marbled murrelet population. Under the Plan, monitoring is an essential component and is designed to help managers understand the degree to which the Plan is meeting this objective. This report describes methods used to assess the status and trend of marbled murrelet populations under the Plan.

Book excerpt: The marbled murrelet is a small, nondescript seabird that was federally listed as threatened under the Endangered Species Act in 1992. This species has a unique natural history among seabirds in that it travels up to 50 mi inland away from the ocean to establish nest sites in the canopies of large trees in older-successional forests (Hammer and Nelson 1995)

This book was released on 2015-06-26 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marbled murrelets (Brachyramphus marmoratus) range from Alaska to California and are federally listed under the U.S. Endangered Species Act as threatened in Washington, Oregon, and California (USFWS 1997). Recovery of the murrelet depends, in large part, on conservation and restoration of breeding habitat on federally managed lands. Conservation of murrelet nesting habitat was one of the major objectives of the Northwest Forest Plan (hereafter the Plan). Under the Plan, the goal was to conserve and restore nesting habitat on federally administered lands that will sustain a viable murrelet population (FEMAT 1993). Monitoring is an essential component of the Plan and is meant to help managers understand the degree to which the Plan is meeting this objective. This report describes the methods used to assess the status and trend of the marbled murrelet in the portion of its range covered by the Plan.
