Mineral resource potential map of the Natural Area Roadless Area, Baker County, Florida
James B. Cathcart, Sam H. Patterson, Thomas M. Crandall
1983, Miscellaneous Field Studies Map 1572-B
The Natural Area Roadless Area, which is in the Osceola National Forest in Baker County, Fla., is underlain by sedimentary rocks containing phosphate deposits that are not a potential mineral resource by todays standards. The region has a low potential for oil and gas and virtually no potential for other...
Maps showing the distribution and relationships of selected metals in heavy-mineral concentrates of the Hells Hole Further Planning Area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico
J.R. Hassemer, K. C. Watts, C.L. Forn, E. L. Mosier
1983, Miscellaneous Field Studies Map 1344-D
The Wilderness Act (Public Law 99-577, Sept. 3, 1964) and related acts require the U.S. Geological Survey and the U.S. Bureau of Mines to survey certain areas on Federal lands to determine their mineral resource potential.  Results must be made available to the public and be submitted to the President...
Maps showing aeromagnetic data and interpretation for the Kalmiopsis Wilderness, southwestern Oregon
Richard J. Blakely, Norman J. Page, Floyd Gray, Lisa Senior, Holly F. Ryan
1983, Miscellaneous Field Studies Map 1240-D
The distinctive magnetic properties of the major rock types in the Kalmiopsis Wilderness of southwestern Oregon facilitate interpretation of aeromagenetic data. The region is composed of tectonic slices of magnetic ultramafic, gabboric, and other ophiolitic rocks faulted against  the realitively nonmagnetic Dothan Formation, the equivalent of the Franciscan Complex of...
Habitat Suitability Index Models: Smallmouth bass
Elizabeth A. Edwards, Glen Gebhart, O. Eugene Maughan
1983, FWS/OBS 82/10.36
A review and synthesis of existing information were used to develop riverine and lacustrine habitat models for Smallmouth bass (Micropterus dolomieui), a freshwater species. The models are scaled to produce an index of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat) for freshwater areas of the continental...
Habitat Suitability Index Models: Wood duck
Patrick J. Sousa, Adrian H. Farmer
1983, FWS/OBS 82/10.43
A review and synthesis of existing information were used to develop models for breeding and wintering habitats for the wood duck (Aix sponsa). The models are scaled to produce indices of habitat suitability between 0 (unsuitable habitat) and 1 (optimally suitable habitat). Habitat suitability indices are designed for use with Habitat Evaluation Procedures previously...
Habitat Suitability Index Models: Roseate spoonbill
James C. Lewis
1983, FWS/OBS 82/10.50
The roseate spoonbill is a long-legged wading bird with a height of approximately 80 cm (31.5 inches), a wingspan of 1.3 m (4.3 ft), and a weight of 1.6 kg (3.5 Ib }. The bill is narrower near the base (2-3 em, 0.8-1.2 inches) than at the flattened tip (5...
Habitat Suitability Index Models: Alewife and blueback herring
Garland B. Pardue
1983, FWS/OBS 82/10.58
Alewives and blueback herring are anadromous clupeids found along the Atlantic coast in marine, estuarine, and riverine habitats, depending upon life stage. Both are important commercial species, used fresh or salted for human consumption, and used as crab bait, fish meal (particularly in animal food manufacturing), and fish oil. Alewife...
