Understory competition for resources in Pinus ponderosa forests of northeastern Oregon

Creator:: Riegel, Gregg M.
Abstract:: The objective of this research was to determine which environmental resources, light, water, and nutrients, control understory plant production and composition in a Pinus ponderosa forest in northeastern Oregon. A split-plot experimental design, with three blocks, four treatments, and 44 plots, was established in the summer of 1985. Twenty plots...

The influence of environmental attributes on temporal and structural dynamics of western juniper woodland development and associated fuel loading characteristics

Creator:: Johnson, Dustin D.
Abstract:: Since European American settlement of the Intermountain Region, dramatic changes in vegetation composition and structure have occurred in the sagebrush steppe ecosystem. Western juniper (Juniperus occidentalis spp. occidentalis Vasek), although indigenous to the Intermountain Region, has increased since the late 1800s. Considerable work has been done documenting juniper woodland expansion...

Soil and understory vegetation characteristics of a tractor-logged forest in eastern Oregon

Creator:: Snider, Michael Duane
Abstract:: A 1.5 ha mixed conifer stand in the Blue Mountains of Oregon was intensively examined to assess the impact of logging disturbance on soils and herbaceous vegetation. Sampling was conducted six years after much of the timber overstory was removed in a shelterwood cut and yarded by crawler tractor. A...

Understory vegetation response and nitrogen cycling following cutting of western juniper

Creator:: Bates, Jonathan D.
Abstract:: Since the late 1880's western juniper has expanded in range and increased in density in sagebrush-bunchgrass, riparian, and forested plant communities of the Pacific Northwest. Succession to western juniper woodland has been shown to reduce the productivity and diversity of the understory component, result in concentration of soil nutrients beneath...

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...

Community structure of old-growth Juniperus occidentalis woodlands

Creator:: Waichler, Wendy Sims
Abstract:: Knowledge of old-growth Juniperus occidentalis woodlands, which occur in central and eastern Oregon, is limited. Wise management of these woodlands necessitates a better understanding of the community ecology. The community structure of woodlands at seven sites in three areas of central Oregon was studied. Measurements taken at nine plots per...

"The Island" Research Natural Area : a vegetation study with time and location comparisons

Creator:: Fox, M. Anne, 1939-
Abstract:: The purpose of this study was to document vegetation on "The Island", a Research Natural Area at the confluence of the Crooked River and the Deschutes River in central Oregon's Juniperus occidentalis Zone and to compare the results with an earlier study reported in 1964 from 1960-'61 data. Present-day comparisons...

Quantification of vegetation diversity and variation on intact and degraded rangelands

Creator:: Dysart, Patricia L.
Abstract:: Vegetation diversity in the Wyoming big sagebrush/Thurber needlegrass (Artemisia tridentata Nutt. ssp. wyomingensis Beetle & Young/Achnatherum thurberianum (Piper) Barkworth. syn. Stipa thurberiana Piper) plant association was studied across a condition class gradient in southeastern Oregon. All observable vascular plant species were counted during 6 seasons and 2 years and diversity...

Spatial and temporal changes of sage grouse habitat in the sagebrush biome

Creator:: Miller, Richard F., Eddleman, Lee, and Oregon State University. Agricultural Experiment Station
Abstract:: This paper was written as a book chapter on the ecology and biology of sage grouse. Because the book was never fully developed, we chose to publish the information with the OSU Agricultural Experiment Station.
