Malheur Reservoir in Malheur County, Oregon, was chemically treated on October 11, 1962, to eliminate an abundant population of black crappie and a smaller population of finescale suckers and redsided shiners. A total of 1,100 gallons of liquid synergized rotenone (Pro-Noxfish) was used to establish a toxicity of 1.5 p.p.m....
The objectives of this study were to determine the
location and extent of populations of pygmy rabbits in Oregon,
and to describe several biotic and physical components within
communities that include pygmy rabbits. Interpretation of
aerial photographs, and information obtained from soil maps
and interviews with biologists and area residents,...
Home range and habitat use by pileated woodpeckers
(Dryocopus pileatus) were studied in the Coast Ranges of western
Oregon. Radio-telemetry was used to determine home ranges of 11
woodpeckers and habitat use of 14 woodpeckers after young had
fledged during summers from 1982 to 1985. Home range size for
individual...
Wildlife is an integral part of woodlands. Where there are forests,
meadows, and streams, there is wildlife. Wildlife means many
things to people, but for purposes of our discussion we’ll divide
it into three basic categories. The most common category is game—birds
and mammals that one hunts for recreation, fur,...
I investigated habitat use and home range size of northern goshawks in the southern Cascades, in the Shasta- Trinity and Klamath National Forests of northern California. My objectives were to 1) estimate the average home range and 2) describe the use of habitats within home ranges by breeding goshawks. Ten...
One of the goals of ecosystem management is to integrate management of many species and processes across a range of temporal and spatial scales. I investigated the relationship between small mammals and amphibians at 3 spatial scales. My objective
was to identify, habitat associations of forest floor vertebrates at the...
Forest floor vertebrate species presence and abundance may be influenced by the volume and cover of coarse woody debris (CWD) in managed forests. I studied macro- and microhabitat associations of vertebrate species in 18 closed-canopy stands ranging in CWD volume from 14 to 859 m3/ha. Pitfall traps were used to...
