Aeromagnetic map and interpretation of geophysical data from the Condrey Mountain Roadless Area, Siskiyou County, California
R.C. Jachens, W.P. Elder
1983, Miscellaneous Field Studies Map 1540-B
The Condrey Mountain Roadless Area lies within the Klamath Mountains geologic province, a province composed of four eastward-dipping imbricate thrust slices or belts consisting predominantly of marine arc-related volcanic and sedimentary rocks, but also including significant amounts of ultramafic and other ophiolitic rocks (Irwin, 1981). From west to east the...
Geochemical maps of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
Berton W. Coxe, Margo I. Toth
1983, Miscellaneous Field Studies Map 1495-C
The Selway-Bitterroot Wilderness covers almost 2,000 mi2 in east-central Idaho and western Montana (fig. 1). The wilderness lies across the Bitterroot Range, which forms the boundary between Idaho and Montana, and includes large portions of the drainages of the Selway, Lochsa, and Bitterroot Rivers. Elevations range from 1,800 ft on...
Habitat Suitability Index Models: Yellow perch
Douglas A. Krieger, James W. Terrell, Patrick C. Nelson
1983, FWS/OBS 82/10.55
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for yellow perch (Perca flavescens). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for riverine, lacustrine, and palustrine habitat in the 48...
Habitat Suitability Index Models: Northern Gulf of Mexico brown shrimp and white shrimp
Robert Eugene Turner, Michael S. Brody
1983, FWS/OBS 82/10.54
A review and synthesis of existing information were used to develop estuarine habitat models for brown shrimp (Penaeus aztecus) and white shrimp (Penaeus setiferus). The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) to 1 (optimally suitable habitat) for estuarine areas of the northern...
Mineral resource potential map of the Gee Creek Wilderness, Polk and Monroe counties, Tennessee
Jack B. Epstein, Gertrude C. Gazdik, Paul T. Behum
1983, Miscellaneous Field Studies Map 1474-D
The Gee Creek Wilderness comprises 2,493 acres (nearly 4 square miles) in the Cherokee National Forest, Polk and Monroe Counties, Tennessee, about 4 miles (6 km) southeast of Etowah, Tenn., and about 20 miles northeast of Cleveland, Tenn. All of the surface in the wilderness is in U.S. Government ownership;...
Habitat suitability index models: redhead (wintering)
Rebecca J. Howard, Harold A. Kantrud
1983, FWS/OBS 82/10.53
The redhead is a North American waterfowl species with economic as well as ecological importance. It is highly desired by hunters. Retrieved redhead kill in the United States averaged 143,000 birds during the three waterfowl seasons from 1975 to 1977 (U.S. Department of the Interior 1981a, 1981b). Populations on the...
Habitat Suitability Index Models: Southern red-backed vole (western United States)
Arthur W. Allen
1983, FWS/OBS 82/10.42
Habitat preferences of the southern red-backed vole (Clethrionomys gapperi) are described in this publication, which is one of a series of Habitat Suitability Index (HSI) models. A review and synthesis of the literature is followed by development of a model of the species-habitat requirements of the southern red-backed vole. Habitat suitability...
Habitat Suitability Index Models: Clapper rail
James C. Lewis, Russell L. Garrison
1983, FWS/OBS 82/10.51
A review and synthesis of existing information were used to develop a model suitable for evaluating the quality of coastal habitat of clapper rails (Rallus longirostris). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for coastal areas of...
Habitat Suitability Index Models: Coho salmon
Thomas E. McMahon
1983, FWS/OBS 82/10.49
The coho salmon (Oncorhynchus kisutch) is native to the northern Pacific Ocean, spawning and rearing in streams from Monterey Bay, California, to Point Hope, Alaska, and southward along the Asiatic coast to Japan. Its center of abundance in North America is from Oregon to Alaska (Briggs 1953; Godfrey 1965; Hart...
Habitat Suitability Index Models: Black-capped chickadee
Richard L. Schroeder
1983, FWS/OBS 82/10.37
A review and synthesis of existing information was used to develop a habitat model for the black-capped chickadee (Parus atricapillus). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for areas of the continental United States. Habitat suitability indexes...
Habitat Suitability Index Models: Downy woodpecker
Richard L. Schroeder
1983, FWS/OBS 82/10.38
A review and synthesis of existing information was used to develop a habitat model for the downy woodpecker (Picoides eubescens). The model is scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for areas of the continental United States. Habitat suitability indexes...
