Oregon Department of Forestry Marbled Murrelet Management Areas
thumbnail
This package contains 13 polygon layers representing baseline and predicted future climate niches (2050s & 2080s) of Marbled Murrelet (Brachyramphus marmoratus). The modeling algorithm Maxent and the Worldclim predictor set have been used to compute niche projections under two emission scenarios (A1B & A2A) based on three general circulation models (CSIRO, CCCMA & HADCM3). The shapefiles are derived from gridded model outputs with a grid cell resolution of 30 arc-seconds.

This theme maps Late-Successional Reserves associated with occupied marbled murrelet sites. The criteria for mapping these areas are identified on pages C-10 of the Northwest Forest Plan Standards and Guidelines( See Supplemental Info). Supplemental direction to the administrative units in BLM IM OR-2003-001 stated that protection will be afforded to all contiguous existing habitat and recruitment habitat (stands that are capable of becoming murrelet habitats within 25 years) for marbled murrelets within a ½-mile radius of any site where occupation behavior (e.g., active nest, fecal ring, eggshell fragments, or birds flying low, through, into or out of the forest canopy within or adjacent to a stand) has been verified....

This theme describes simulated Future Marbled Murelet Sites that have been developed by randomly selecting forest stands based on a series of criteria known to be important for Marbled Murrelet habitat.

This dataset depicts Marbled Murrelet Habitat within Western Oregon, compiled for the U.S. Bureau of Land Management's Western Oregon Plan Revision project. No additional metadata describing the methods used to determine habitat was available from the BLM.

This dataset maps Late-Successional Reserves (LSR) associated with occupied marbled murrelet sites. The criteria for mapping these areas are identified on pages C-10 of the Northwest Forest Plan Standards and Guidelines( See Supplemental Info). Supplemental direction to the administrative units in BLM IM OR-2003-001 stated that protection will be afforded to all contiguous existing habitat and recruitment habitat (stands that are capable of becoming murrelet habitats within 25 years) for marbled murrelets within a 1/2 mile radius of any site where occupation behavior (e.g., active nest, fecal ring, eggshell fragments, or birds flying low, through, into or out of the forest canopy within or adjacent to a stand) has...

This coverage represents marbled murrelet survey efforts across BLM lands, to locate those areas that exhibit Marbled Murrelet occupying behaviors and those areas that don't.These datasets were obtained from districts Coos Bay, Eugene, Roseburg and Salem for the Western Oregon Plan Revision (WOPR) current as of August 2007.BLM (Bureau of Land Management) WOPR (Western Oregon Plan Revision) WARNING: This dataset was developed specifically for WOPR and may not contain the most current operational data

In 2017-2019, USGS Western Ecological Research Center (USGS WERC) partnered with California State Parks to continue long-term, at-sea surveys to estimate at-sea abundance and juvenile (i.e. hatch-year) productivity of Marbled Murrelets (Brachyramphus marmoratus) in U.S. Fish and Wildlife Service Conservation Zone 6 (central California: San Francisco Bay to Monterey Bay). Marbled Murrelets have been listed as “Endangered” by the State of California and “Threatened” by the U.S. Fish and Wildlife Service since 1992. Marbled Murrelets have been surveyed at sea off central California since 1995 (Becker et al. 1997), and standardized surveys to estimate abundance and productivity have been conducted since 1999 (excluding...

This theme shows the two conservation recovery zones for Marbled Murrelet (Brachyramphus marmoratus) that fall within the WOPR boundary. The first zone comprises the area from the coast to a line mirroring the coast thirty-five miles inland, north of a line running due east from North Bend, Oregon. The second zone comprises the area from the coast to a line mirroring the coast thirty-five miles inland, south of a line running due east of North Bend, Oregon. This dataset has been "clipped" to the WOPR boundary for Alternative analysis.BLM: (Bureau of Land Management) WOPR: (Western Oregon Plan Revision) PRMP: (Proposed Resource Management Plan) Conservation Zones Description: Six conservation zones were designated...

This theme shows the two zones for Marbled Murrelet (Brachyramphus marmoratus). The first zone comprises the area from the coast to a line mirroring the coast thirty-five miles inland. The second zone comprises the area from the eastern edge of the first zone and north of the Medford BLM district boundary to a line mirroring the coast fifty miles inland. The southern sections of this zone have been adjusted from the original zones, for WOPR purposes. These zones show the areas of Marbled Murrelet habitat with most of the population occurring closer to the coast. This dataset has been "clipped" to the Western Oregon Plan Revision (WOPR) boundary.BLM: (Bureau of Land Management) WOPR: (Western Oregon Plan Revision)...

This dataset represents Marbled Murrelet designated Critical Habitat under Section 4 of the Endangered Species Act within Western Oregon for the Bureau of Land Management's Western Oregon Plan Revision Project (WOPR), assigned to whole Forest Operations Inventory (FOI) units. All FOI units with greater than 20% area covered by marbled murrelet designated habitat were initially selected; the dataset was then aligned with the federal register descriptions of designated habitat.
