Madsen, Sarah; Evans, Diane; Hamer, Thomas; Henson, Paul; Miller, Sherri; Nelson, S. Kim; Roby, Daniel; Stapanian, Martin. 1999. Marbled murrelet effectiveness monitoring plan for the Northwest Forest Plan. Gen. Tech. Rep. PNW-GTR-439. Portland, OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 51 p. This report describes options for effectiveness monitoring of long-term status and trends to evaluate the success of the Northwest Forest Plan in maintaining and restoring marbled murrelet nesting habitat and populations on Federal lands. A two-phase approach is described that begins with developing reliable and repeatable processes for identifying nesting habitat and overcoming logistical and statistical problems before habitat and population trends can be accurately assessed. The second phase involves application of these processes to mapping and quantifying nesting habitat, and establishing populations in the Forest Plan area. The potential use of predictive models to evaluate the relation between terrestrial habitat use and conditions and population densities and trends is described along with a process for data analysis and reporting.

Ecology and Conservation of the Marbled Murrelet in North America: an Overview
Over the past decade, the Marbled Murrelet has become a focus of much controversy. It was listed as threatened in Washington, Oregon, and California by the U.S. Fish and Wildlife Service in February 1993. In order to aid the various agencies with management, the Marbled Murrelet Conservation Assessment was formed to bring together scientists, managers, and others to gather all the available dat...
متن کاملLand and Seascape Patterns Associated with Marbled Murrelet Abundance Offshore
─We measured offshore Marbled Murrelet (Brachyramphus marmoratus) abundance from April through October between 1989 and 1998, in northern California and southern Oregon and investigated its relationships with marine and terrestrial habitats. We found that higher murrelet abundance offshore was strongly related to the presence of large, clustered and unfragmented old-growth forests on nearby inl...

The marbled murrelet Brachyramphus marmoratus is an old-growth dependent species that nests in North American coastal forests. Canadian populations and occurrence data are limited; however concern over loss of nesting habitat in coastal British Columbia led to an assessment of ‘threatened’ by the Committee on the Status of Endangered Wildlife in Canada, and subsequent listing under the Canadian...
متن کاملRelationship of Marbled Murrelets with Habitat Characteristics at Inland Sites in California
We examined the range and the relationships of Marbled Murrelet (Brachyramphus marmoratus) behavior with habitat and landscape characteristics in isolated old-growth and residual forest stands from 2 to 400 ha in California. In large contiguous stands of old-growth forest in parks, we examined relationships of murrelet detections with elevation and topography. In isolated stands we found higher...
