Plant communities in the old-growth forests of North Coastal Oregon

Creator:: Hines, William W. (William Wester)
Abstract:: 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...

Understory response to tree harvesting in pinyon-juniper woodlands

Creator:: Everett, Richard L.
Abstract:: Understory species associations and their association with tree species were examined on three intensively studied stands. We studied the chronosequence of understory species associated with different aged singleleaf pinyon (Pinus monophylla Torr. and Frem.) trees. Mid- to late pinyon-juniper understory succession was found to be more spatial than floristic in...

Regional gradient analysis and spatial pattern of woody plant communities in Oregon

Creator:: Ohmann, Janet L.
Abstract:: Knowledge of regional-scale patterns of plant community structure and controlling factors is largely qualitative and based on numerous local studies. Data from a subsample of 10,000 field plots were used to quantify and map compositional gradients of woody plant communities across Oregon forests. Canonical correspondence analyses explained 9-14% of the...

The quantity and composition of ground vegetation in different light environments under a Douglas-fir, Pseudotsuga menziesii (Mirb) Franco, stand in the Oregon Coast Range

Creator:: Temmes, Eeva Karin Marianna
Abstract:: The relationship between ground vegetation and light intensity under a 60 to 65-year-old Douglas-fir forest was investigated. Biomass and height of ground vegetation were measured and cover was estimated on small sample units (30 centimeters in diameter) on permanent research plots, one-acre in size, on the George T. Gerlinger Experimental...

Nitrogen status in Oregon Coast Range forest communities

Creator:: Alexander, Joseph Richard
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) roots in four plant communities--ocean spray (Holodiscus discolor (Pursh). Maxim.)/salal (Gaultheria shallon Pursh), vine maple (Acer circinatum Pursh)/salal, sword-fern (Polystichum munitum (Kaulf.) Presi. var. munitum) and sword-f ern/oxalis (Oxalis oregana Nutt.)--were sampled for soluble nitrogen concentrations. Sampling prior to bud burst in the salal communities...

Vegetation classification for the badger allotment, Mt. Hood National Forest

Creator:: Williams, Clinton K.
Abstract:: More than 200 sites between 500 and 2000 meters elevation were examined utilizing a reconnaissance sampling technique for a portion of the eastern slopes of the northern Oregon Cascade Mountains. Twelve different forested plant communities were described with data on vegetation, soils and topography. A map of their distribution and...
