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...

Summertime stream temperatures in the North and South Forks of the Sprague River, south central Oregon

Creator:

Friedrichsen, Paul T.

Abstract:

The Upper Sprague River Watershed (North and South Forks of the Sprague River) in south central Oregon provides important habitat for salmonid species, including native bull trout (Salvelinus confluentus) and redband trout (Oncorhynchus mykiss ssp.). Concern over the loss of viable habitat for these species has increased due to reductions...

Abstract:

Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...

Abstract:

Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al.

Abundance and habitat associations of Washington ground squirrels in north-central Oregon

Creator:

Greene, Eric

Abstract:

Much of the Columbia River Basin has been cultivated for agriculture, which has reduced and fragmented the native shrub-steppe habitats. As a result, the range of the Washington ground squirrel (Spermophilus washingtoni) has been significantly reduced, prompting the states of Washington and Oregon to review their status. Consequently, I investigated...
