This research employed multivariate analytical techniques to
statistically examine the relationship between individual soillandscape
units (SLUs) in Southeastern Oregon and their associated
sagebrush communities. The objective was to determine if soil properties
between SLUs differed, describe the variation, and verify that
these differences were reflected in the taxonomic class of...
Natural disasters are an increasingly costly and frequent occurrence globally and in the United States (IPCC, 2012; IPCC, 2014; Berlemann & Steinhardt, 2017). Discrete disaster events, such as coastal flooding, have been shown to be push factors in temporary and long-term migration (Black et al., 2013). Policy efforts to adapt...
Streams and rivers play a critical role in global carbon (C) cycling by processing, storing, and transporting C. Headwater streams which make up more than 95% of the length of streams and rivers worldwide have disproportionate influence on fluvial C dynamics. The hyporheic zone (HZ) of headwater streams is a...
As part of investigations to evaluate the suitability of sheep grazing in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range, this research was designed to evaluate the effectiveness of sheep grazing in suppressing unwanted vegetation, determine seasonal variations in forage quality, and investigate the impact of sheep grazing on big...
In this dissertation, I examine emerging economic issues which intersect outdoor recreation, environmental quality, public land use, and public health advisories. First, I explore the potential impacts of social media on visitation to public land. Social media, and in particular Instagram, has been suggested by journalist and land managers as...
Two tributaries of the south fork of the Burnt River, near Unity Oregon were studied
during the summers of 2000 and 2001 to determine water heating and cooling
patterns. Hourly temperature data were recorded for air, water, and soil parameters
at four elevations 150m apart on Barney and Stevens Creeks....
A study was conducted to determine effects of year and season on diet quality of beef cattle grazing northern Great Basin rangelands from 1990 to 1993. Forage quality was high early in the growing season, then declined as seasons progressed (P<.05). Plant chemical composition was higher early in the growing...
Developed coastlines provide a variety of recreation opportunities to coastal residents and visitors but are also the first line of defense for oceanfront development against chronic hazards like erosion and sea level rise. In the Pacific Northwest of the United States, oceanfront homes also face an additional severe but very...
