The structure of two oak woodland types in the Santa Rosa region
of the Santa Ana Mountains of southern California has been described
by Zuill (1967). One type called the grass oak woodland (GOW) is
composed mainly of Q. engelmannii on hills and slopes. The other
type called the dense...
In 1970 a phytosociological reconnaissance consisting of 135 plots in the Subalpine Meadow Zone was made. These samples were sorted using an association table and several Alpine Zone and very early seral communities were set aside, An additional hundred plots taken by M. J. Hamann were
incorporated with these and...
Setaria lutescens (yellow foxtail) plants, grown from five seed
sources were compared in California. Seed sources were: Connecticut,
Iowa, Massachusetts, Pennsylvania and California. Morphological
and physiological differences between biotypes include: plant
size, growth habit, time required to mature and reproductive capa
city. Most significant is the prostrate habit of the...
During the summers of 1971, 1972, and 1973, a general
floristic ecological survey of the naturally-occurring vegetation
of the Bear River Migratory Bird Refuge in Utah was
carried out. Ten community types were identified and
characterized. These included two aquatic communities, the
Potamogeton pectinatus (Pope) and the Ruppia maritima/
Zannichellia...
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...
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 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...
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...
