The vegetative communities in the subalpine meadows of Hunts
Cove, Mt. Jefferson, and some of the major environmental factors
affecting them were studied in the summer of 1971. Hunts Cove is in
the subalpine Tsuga mertensiana parkland of the Central Oregon High
Cascades. Habitats within the Cove vary considerably; elevation...
The objectives of this study are to: 1) study the variations
among stands of old-growth Sitka spruce forest located within a relatively
restricted geographical area, 2) determine the relationship between
species distribution, vegetational pattern, and such site factors
as slope and aspect, and 3) ascertain the abruptness of phytosociological
change...
The purpose of this study was to determine plant species composition, community structure, successional relationships, vegetational development and plant distributions in estuarine salt marshes on the Pacific Coast of Oregon.
Quadrat and transect samples of plant presence and cover, collected from April 1971 - June 1974, were subjected to phytosociological...
The purpose of this study was to develope a plant community classification
within the Siskiyou mountains, a small range within the Klamath
geological province well known for its geologic and floristic diversity.
Forest land managers have expressed the need for identification of
basic Land classes that will aid in the...
In an effort to describe the plant communities and
succession of the Oregon coastal grasslands, vegetation
and environmental data were collected from 75 stands at
24 separate locations ranging from Cape Falcon in Tillamook
County to Cape Ferrelo in Curry County. The vegetation
data consisted of cover and frequency values...
Ecological factors associated with the relictual distribution of
the endemic shrub Kalmiopsis leachiana (Ericaceae) were investigated.
A prostrate evergreen species with small coriaceous leaves,
K. leachiana is restricted to two disjunct populations in the Siskiyou
Mountains and southern Cascade Mountains of southwestern Oregon,
USA. Exact distributions of individual populations were...
Grassy balds are meadows that occur on or near the summits of montane peaks and ridges. The sites on which balds are located generally fall within the climatic tolerance ranges of associated tree species. This study evaluates the stability of a forest-meadow transition zone of such a bald on Marys...
