The seasonal yield, quality, and utilization of Trifolium subterraneum in mixture with festuca arundinacea and Lolium perenne in western Oregon

Creator:: Sanders, Kenneth D. (Kenneth Dwayne), 1940-
Abstract:: In 1959, a large scale grazing study in western Oregon was initiated to compare the value of perennial ryegrass (Lolium perenne L.) with subclover (Trifolium subterraneum L.) and tall fescue (Festuca arundinacea Schreb.) with subclover, and to evaluate common use grazing on them. The present investigation was undertaken to determine...

Evaluation of species composition by four methods on two perennial grass pastures (Festuca arundinacae Schreb. and Lolium perenne L.) grazed lightly and heavily in western Oregon

Creator:: Pessot Zorich, Rafael
Abstract:: The present study was undertaken to evaluate the seasonal botanical composition of two grass pastures, tall fescue (Festuca arundinacea Schreb.) and perennial ryegrass (Lolium perenne L.). Botanical composition was determined by four methods: dry-weight-rank, weight-estimate, hand separation, and the constituent differential, with cattle and sheep grazing at two intensities. The...

Methodology for cuticular identification of selected eastern Oregon range plants

Creator:: Schrumpf, Barry J.
Abstract:: Animal dietary preferences have been studied by feeding-site examinations, animal observation, and stomach and esophageal collections. Analysis of fecal material for undigested plant cuticle is another means for obtaining the same information. This study was conducted to: (1) prepare a microscope slide series depicting the surface features of leaves and...

An ecological reconnaissance of the artemisia steppe on the east central Owyee uplands of Oregon

Creator:: Culver, Roger Norman
Abstract:: As the management of range lands is intensified or as improvement activity is increased, a critical need is seen to refine the understanding of the ecology of these lands. If soil surveys on range lands are to be meaningful and useful, the relationship between the fundamental ecological units and the...

Phytosociology of the ponderosa pine type on pumice soils in the Upper Williamson River Basin, Klamath County, Oregon

Creator:: Volland, Leonard A.
Abstract:: The study was conducted over approximately 191,000 acres in central Klamath County, Oregon. The research had three objectives: first, to describe and classify the seral and near-climax vegetation by using polyclimax principles; secondly, to determine the southern extension of five plant associations and one plant associes as previously described by...

Characterization of selected plant communities within the Tillamook Burn in northwestern Oregon

Creator:: Bailey, Arthur W.
Abstract:: A study was initiated in 1961 to characterize seral plant communities in a part of the Cedar Creek drainage in the Tillamook Burn. Stratification of vegetation into ecological units was a necessary first step in conifer-animal damage studies supported by the Oregon State Game Commission. Reconnaissance information was recorded in...
