The response of soils, streambanks and instream coliform bacteria levels to grazing management in a riparian area

Creator:: Bohn, Carolyn C.
Abstract:: This thesis describes a case study of the effects of five systems of grazing on watershed values in a deteriorated riparian area. Soil infiltration, bulk density and penetrability, streambank edge movement and coliform bacteria were monitored for seven years along a stream in the Blue Mountains of northeastern Oregon. For...

Correlation of riparian vegetation and stream attributes

Creator:: Miller, Rachel Ann, 1968-
Abstract:: Riparian plant assemblages give clues of the conditions of the soil and other physical characteristics of their stream-side environment. The plight of the spring/summer, and fall Snake River chinook salmon has aroused interest in fish habitat and the effects of riparian plants on fish habitat. This study was launched to...

Coarse woody debris in streams of the Drift Creek Basin, Oregon

Creator:: Veldhuisen, Curt N.
Abstract:: This study examined the occurrence of coarse woody debris (i.e., pieces greater than 0.15 m in diameter and 2.0 m in length) in first- through fifth-order streams located within the Drift Creek Basin of the Oregon Coast Range. Nine "tributary reaches" were surveyed to determine how three land management treatments...

Evaluating the restoration potential of black cottonwood (Populus trichocarpa) from multiple scales of observation, Grande Ronde River Basin, Oregon, USA

Creator:: Hines, Cynthia A.
Abstract:: As a key factor contributing to slope stability, in-stream habitat for aquatic species (e.g., salmonids), nutrient cycling, and corridors for upland species, riparian vegetation and its maintenance is of critical conservation importance. Subsequently, the chronic degradation of aquatic and riparian ecosystems in the semi-arid and arid landscapes of the western...

A characterization of unmanaged riparian overstories in the central Oregon Coast Range

Creator:: Nierenberg, Tara R.
Abstract:: Riparian areas that can be used as reference sites on which to base goals of vegetation restoration have not been documented in the Oregon Coast Range. I examined the composition and distribution of unmanaged riparian overstories in the central Oregon Coast Range along nine streams which have experienced minimal disturbance...

Estimating large woody debris recruitment from adjacent riparian areas

Creator:: Minor, Kathleen P.
Abstract:: Large woody debris recruitment to streams from adjacent riparian forests influences stream channel morphology, sediment routing, and fish habitat. A mathematical model was developed to 1) determine whether the trees in a stand adjacent to a stream, upon falling, would provide large woody debris of a specified size to the...

Ecology of aquatic habitats associated with stream margins

Creator:: Moore, Kelly M. S.
Abstract:: The morphology and ecological importance of habitats associated with the margin of third-order stream channels in the Oregon Cascades were studied in streams in three different riparian types: 450-year-old conifers, 40-year-old alder, and an open, herbaceous-dominated clearcut. Margins, backwaters, and side channels in streams create important habitat for fry of...

Riparian vegetation and abundance of woody debris in streams of southwestern Oregon

Creator:: Ursitti, Victoria L.
Abstract:: Riparian vegetation (trees > 10 cm dbh), woody debris (> 10 cm diam, > 1 m long), channel, and landform characteristics were inventoried in mature (80-150 yrs) and old-growth riparian areas (>250 yrs) selected from small tributaries of the Coos and Coquille River basins in southwestern Oregon. Basal area of...

Comparison of stand development of a deciduous-dominated riparian forest and a coniferous-dominated riparian forest in the Oregon Coast Range

Creator:: Poage, Nathan Jeremy
Abstract:: Riparian forests in the central Oregon Coast Range vary along a coniferous-deciduous compositional continuum. Variations in structure and composition affect water quality, fish and wildlife, biodiversity, timber, and aesthetics. A retrospective approach was taken in this study in order to understand and compare the structure, pattern, and history of an...

Ecology of the Salix and Populus species of the Crooked River National Grassland

Creator:: Busse, Kathryn Grace
Abstract:: Riparian communities dominated by members of the Salicaceae (Salix lasiandra, S. lutea, S. lemmonii, Populus trichocarpa, P. tremuloides and S. exiqua) were studied at the Crooked River National Grassland in central Oregon. The objectives of this study were to examine the relationships between the Salix and Populus species and microsite...
