A study of the McKenzie River floodplains, terraces and glacial
outwash plains was undertaken to classify and describe the vegetation
and soils of a previously little studied synecological unit.
During the summer of 1971, 54 analytic vegetation and soil
plots (stands) were studied. Cover and frequency of all trees, shrubs,...
Seedlings from 25 provenances of Abies grandis and Abies
concolor were studied at two plantations, 12 at Philomath, Oregon,
and 13 at Camino, California. Native seedlings were studied at four
of the provenances' field sites. Stomatal infiltration pressure
measurements and plant moisture stress measurements were made
throughout one summer on...
The objectives of this study include: (1) analysis of Chamaecyparis
lawsoniana, C. taiwanensis, and C. formosensis forests including
the structure, composition, and dynamics of plant communities and
their environmental relationships; and (2) comparison of the temperate
Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis
on structural and successional...
Pseudotsuga menziesii dominates the forests of the Pacific Northwest.
But though it is dominat, Tsuaa heteroohylla or Abies amabilis
is usually climax. Many researchers have studied Pseudotsuga on the
widespread mesic sites where it is seral, but few have examined the
relatively rare ecosystems in which Pseudotsuga or its associate...
In 1982 a protohistoric archaeological site along the Applegate River in southwest Oregon was excavated by Oregon State University Department of Anthropology. Three housepits and a possible menstrual but were uncovered with lithic, faunal, and archaeobotanical elements recovered from house floors and hearths. Seven botanical taxa were represented by carbonized...
A study was made of the subgenus Genuini of the genus Juncus in the Pacific States, California, Oregon and Washington. Extensive morphological comparisons, geographical distributions, habitat differences and observations of apparent presence or absence of natural hybrids provided the major data sources. Cytological studies were made, but were inconclusive. Eleven...
