  Citation × Citation Citation Abstract Copy Title: An assessment of community-based adaptive watershed management in three Umpqua Basin Watersheds Author: Habron, Geoffrey Bryan The dissertation introduces community-based adaptive watershed management (CAWM) as a holistic conservation framework. The CAWM framework integrates social and ecological suitability to achieve conservation outcomes. The core theoretical concepts consist of adaptive management, adoption-diffusion, symbolic interactionism, community-based conservation, spatial analysis and watershed management. The CAWM framework is applied to the Calapooya Creek, Deer Creek and Myrtle Creek watersheds within the Umpqua River Basin in Southwestern Oregon. The goal of the research is to facilitate effective watershed restoration outcomes grounded in a solid understanding of social and ecological dynamics. Applying the CAWM framework provides the basis to determine the kinds of conservation practices to implement, the locations in which to implement them and the kinds of programs to stimulate their adoption. Therefore, the dissertation objectives are to: 1) identify agricultural landowner participation in watershed conservation projects; 2) assess the spatial distribution of watershed projects; 3) determine the characteristics of participating and non-participating landowners; and 4) determine the sociocultural, ecological and geographic constraints to adaptive watershed management. Data were collected during 1997-1998 using agricultural landowner interviews, a mail landowner survey and observations of the Umpqua Basin Watershed Council. Landowners' worldviews consist of independence, the importance of private property rights, aversion toward government interference and a belief in environmental resilience. Landowners implement upland conservation practices such as off-stream livestock water developments and rotational grazing more often than riparian fencing, riparian tree planting and installing fish screens on instream irrigation diversions. The key factors in adoption of conservation practices include the use of irrigation, shared management decisions with a spouse, a belief in scientific experimentation and discussion of conservation with others. Spatial analysis using geographic information systems indicate that a suite of conservation practices is needed to achieve a network of large, connected patches throughout the watersheds.

  Citation × Citation Citation Abstract Copy Title: Effects of wildfire on growth and demographics of coastal cutthroat trout in headwater streams Author: Heck, Michael P. Wildfire is a largely terrestrial perturbation broadly recognized as an agent of disturbance and ecological change in forested biomes. Effects of post-fire conditions on biotic components of aquatic systems have been less well-documented, although hypothetically, the two are strongly connected. In fact, the influence of wildfire may be most profound in headwater streams because of the tight linkage between aquatic and terrestrial ecosystems. We sought to understand the influence of post-fire conditions on fish in headwater streams by observing growth and demographics of coastal cutthroat trout (Oncorhynchus clarkii clarkii) following wildfire. During the summer of 2002, wildfire burned portions of three headwater watersheds in the North Umpqua basin of western Oregon. Burn severities ranged from moderate to severe. A reference stream was selected from a nearby fourth watershed. All fish-bearing portions of the stream network in the four watersheds were surveyed for 3 years following the wildfire, and 1,295 scale samples were collected from coastal cutthroat trout for age and growth analysis. Stream temperatures in the burned watersheds changed significantly following the wildfire (p < 0.016), with increases of up to 23% in the most severely burned watershed. During summer electrofishing surveys in the burned watersheds, both young-of-the-year and fish ≥ age 1 were captured; in the unburned watershed, the vast majority of fish captured were ≥ age 1. Age-frequency analyses revealed that fish in older age classes (age ≥ 3) were more prevalent in the unburned watershed than in the burned watersheds. Relative growth rates and length at last annulus formation of coastal cutthroat trout were positively related to the number of degree days during the growing season, and Pearson correlation coefficients ranged from 0.60 (p < 0.07) to 0.90 (p < 0.01). Growth rates and size of fish were not significantly correlated with relative density of fish (p ≥ 0.14). Contrary to the commonly held assumption that wildfire is detrimental to biota in aquatic systems, these results suggest that in the short term (≤ 3 years), fish in the study streams adjusted to environmental change caused by wildfire.
