Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California (open access)

Preliminary Report of Reconnaissance for Uraniferous Granitic Rocks in Montana, Idaho, Oregon, Washington, and California

From abstract: A reconnaissance to determine the uranium content of granitic rocks in the western states was made during parts of October and November 1951. The paucity of our knowledge of the granitic rocks that are most likely to contain significant quantities of uranium has prevented all but a very general isolation of areas or types of granitic rocks for reconnaissance examination.

Developing a Predation Index and Evaluating Ways to Reduce Salmonid Losses to Predation in the Columbia River Basin, Annual Progress Report August 1988-September 1989. (open access)

Developing a Predation Index and Evaluating Ways to Reduce Salmonid Losses to Predation in the Columbia River Basin, Annual Progress Report August 1988-September 1989.

We are reporting progress on the predator-prey study for the period August 28, 1988 to September 1, 1989. The purpose of this research is to evaluate the feasibility of an index for assessment of predation in various reservoirs throughout the Columbia River basin, to describe the relationships among predator-caused mortality of smolts and physical and biological variables; to examine the feasibility of developing bounty, commercial or recreational fisheries on northern squawfish (Ptychocheilus oregonesis); and to develop a plan to evaluate the efficacy of predator control fisheries. Literature searches on predator abundance indexing and factors regulating fish population dynamics have been conducted; selected references have been summarized, and compiled in a key-word bibliography format. The feasibility of various types of predator abundance indices is being assessed; existing data relevant to mark-recapture, catch per unit effort (CPUE), physical and chemical variables, and reservoir morphology have been compiled, reviewed, and summarized. In cases where sufficient data exist, preliminary implementation of predator abundance indices has been demonstrated. Field sampling in John Day Reservoir was conducted during May to August, 1989 -- to continue time series data bases on northern squawfish CPUE and growth, and to evaluate the possibility of year class strength determinations of …

Native and Adapted Grasses for Conservation of Soil and Moisture in the Great Plains and Western States

"The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.

Strawberry Culture: Western United States (open access)

Strawberry Culture: Western United States

"This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3
