Nickel Mining And The Bwca: A Question Of Priorities, Walter E. Parham
Nickel Mining And The Bwca: A Question Of Priorities, Walter E. Parham
Journal of the Minnesota Academy of Science
A conflict in potential land use of the Boundary Waters Canoe Area (BWCA) exists between those who wish to see the area open to mining and those who want it retained as a natural wilderness. A review of information available to the public which relates to possible nickel mining within the BWCA suggests that the BWCA itself in its natural state is a more valuable resource to the people of the United States than it is as a source for nickel. The high U.S. rate of consumption of nickel, our use of nickel in products in which it is non-essential, …

Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince
Fisheries Report No 11 - The Fauna, Flora And Planned Usage Of The Dampier Archipelago, A. A. Burbidge, R. I. T. Prince
Fisheries Research Reports
The Dampier Archipelago is a group of islands off the north west coast of Australia (20 20! - 20 45'S, 116 Cast . 117°E), first discovered by William Dampier in 1699 and subsequently named after him by the Baudin expedition of 1801. This name has since been applied by some authors to include all islands from Roebourne to North West Cape, including both Barrow Island and the Monte Bello Islands, but it is more correctly applied to those islands within a 30 mile radius of the town of Dampier.
Ir. recent times, three parties have visited the Archipelago and examined …

The Colorado Plateau, Robert Durrenberger
The Colorado Plateau, Robert Durrenberger
Canyonlands Research Bibliography
The Colorado Plateau was one of the last areas in the United States to be developed economically. Before the 1880s it was virtually empty except for Indians. Today the vast scenic and energy resources of the area are under development, and projections for future development are frightening. Problems of land use management are directly related to the fragmented nature of landholdings. Present methods of consolidation are inadequate, and new approaches to the organization of space must be devised if further degradation of the environment is to be prevented.
Fisheries Report No. 10 - An Investigation Into The Status Of Introduced Trout (Salmo Spp.) In Western Australia, Dr N. M. Morrissy
Fisheries Report No. 10 - An Investigation Into The Status Of Introduced Trout (Salmo Spp.) In Western Australia, Dr N. M. Morrissy
Fisheries Research Reports
Both brown (Salmo trutta L.) and rainbow (S. gairdnerii trout Richardson) have been introduced into inland waters of the south-west of Western Australia to provide an amateur sport fishery on a gamefish. The large indigenous marron (Cherax tenuimanus Smith) is present in most of these waters. The only large native fish present is the cobbler (Tand- anus bostocki Whitley) which, while highly edible like the marron, has no game-fish qualities.
Hatchery production of trout for stocking waters has been centred at Pemberton in the lower south-west since 1931 when Mr. Cyril Glew, acting in a private capacity, succeeded in hatching …
Water Resources Of Part Of Canyonlands National Park, Southeastern Utah, C. T. Sumsion, E. L. Bolke
Water Resources Of Part Of Canyonlands National Park, Southeastern Utah, C. T. Sumsion, E. L. Bolke
Canyonlands Research Bibliography
Canyonlands National Park is in about the center of the Canyon Lands section of the Colorado Plateaus physiographic province in southeastern Utah. The part of the park discussed embraces an area of about 400 square miles comprising isolated mesas, precipitous canyons, and dissected broad benches near the confluence of the Green and Colorado Rivers, the only perennial streams in the area. The climate is arid to semiarid; normal annual precipitation ranges from less than 8 to about 10 inches. Potential evapotranspiration is about 41 inches annually.
Geology of the park is characterized by nearly horizontal strata that dip gently northward. …
