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...
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...
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...
Forest associations, secondary succession, and relationships
of plant communities to Roosevelt elk were investigated. Stratification
of vegetation into ecological units and an understanding of secondary
succession by habitat-type were a necessary first step in investigations
into browsing of conifers by elk. The study was jointly conducted
by the Oregon State...
The project of which this research was a part is designed to
provide an improved system of ecological resource analysis. Specific
objectives of this study were: (1) classification of plant communities
on the fringes of the sagebrush steppes and the salt desert of
southeastern Oregon, (2) development of symbolic and...
The purpose of the research was to computerize mathematical
procedures for the analysis of range vegetation and environmental
data. The specific objectives were as follows:
1. to develop and apply computer techniques to the classification
of vegetation in order to provide a phytosociological
framework within which to investigate the ecology...
This study was conducted in the old-growth forests of Clatsop,
Tillamook, and Lincoln counties, Oregon. The three objectives of
the research were to describe and classify the near-climax plant
communities found within the forests, to relate the associes described
by a previous study to the forest communities characterized by the...
