Description of the plant communities and succession of the Oregon coast grasslands

Creator:: Ripley, James Douglas
Abstract:: 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...

The structure and dynamics of old-growth Sitka spruce (Picea sitchensis) forest of the Oregon Coast Range

Creator:: Quaye, Eric Charles
Abstract:: 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...

Description and classification of the forests of the upper Illinois River drainage of Southwestern Oregon

Creator:: Atzet, Thomas
Abstract:: 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...

An investigation into the ecology and distribution of Kalmiopsis leachiana (Hend.) Rehder

Creator:: Marquis, Robert John
Abstract:: 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...

Plant communities and succession in Oregon coastal salt marshes

Creator:: Jefferson, Carol A.
Abstract:: 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...

Ecotypic adaptation of Setaria lutescens (Weigel) F. T. Hubbard to alfalfa culture in California

Creator:: Schoner, Carl Arnold
Abstract:: 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...

Synecological features of a natural headland prairie on the Oregon coast

Creator:: Davidson, Eric Duncan
Abstract:: The study of the vegetation of one of the natural coastal prairies in Oregon was undertaken for the purpose of describing some of its synecological features. Specific objectives of the study were to describe certain plant assemblages in the study area, present phenological relationships on some of the assemblages, and...

Synecology of the white-oak (Quercus garryana Douglas) woodlands of the Willamette Valley, Oregon

Creator:: Thilenius, John F., 1931-
Abstract:: Quercus garryana dominated plant communities are found in the interior coastal valleys and on foothills from southeastern Vancouver Island, British Columbia, south to San Francisco, California. They occur as savannas, intermixed with a variety of conifers, and in almost pure stands. The diversity of habitats occupied by the species and...

Succession and certain adaptive features of plants native to the sand dunes of the Oregon coast

Creator:: Kumler, Marion Lawrence, 1941-
Abstract:: The vegetation of the Oregon coast is characterized by a variety of stages of plant succession which are repeated widely throughout the sand dune area. During the years from 1960 to 1963 the gradation of upland sand dune succession was studied on 48 plots within a 150 mile section of...
