  Citation × Citation Citation Abstract Copy Title: Watershed response to western juniper control Author: Deboodt, Timothy L. Western juniper (Juniperus occidentalis) encroachment has been associated with increased soil loss and reduced infiltration resulting in the loss of native herbaceous plant communities and the bird and animal species that rely on them. Hydrologically, however, change in water yield has been linked with the amount of annual precipitation a site received. Studies published in the 1970’s and 1980’s, suggest that a minimum 4500 mm (18 inches) of annual precipitation was necessary before an increase in water yield manifested itself following vegetation manipulation. In 1993, a paired watershed study was initiated in the Camp Creek drainage, a tributary of the Crooked River of central Oregon, to evaluate the impacts of cutting western juniper on the hydrologic function of those sites. The study involved a paired watershed approach using watersheds of approximately 110 hectares (270 acres) each to evaluate changes in a system’s water budget following the reduction of western juniper. The 30 year average annual precipitation for the area is 3500 mm (13.75) and during the study period, annual precipitation ranged from 80 percent to 129 percent of average. In 2005, following 12 years of pretreatment monitoring in the 2 watersheds (Mays and Jensen) all post-European aged juniper (juniper < 140 years of age) were cut from the treatment watershed (Mays). Analysis indicated that juniper reduction significantly increased late season spring flow by 225 percent (alpha > .05), increased days of recorded ground water by an average of 41 days (alpha > .05) and increased the relative availability of late season soil moisture at soil depths of .76 m (27 inches) (alpha > 0.1). Ephemeral channel flow did not show a predictable trend during 2 years of post treatment measurements. Channel flow is dependent on spring snow melt and severe summer thunderstorm activity. When winter soils were greater than 0 degrees Celsius (32 degrees F), the source of channel flow in Mays was observed to be seepage from the channel banks. Channel flow in Jensen appeared to be a result of rock forcing subsurface flows to the surface. Vegetative responses showed significant increases in perennial forb canopy cover (alpha > .01) and annual forb and annual grass basal cover (alpha > .05). Increases were also found in reduction of percent bare ground and increase in shrub cover, but were not significant. A statistically insignificant decrease in perennial grass cover was noted in the treated watershed however a large amount of reproductive culms were noted in the treated watershed in 2007 compared to the control watershed. Hillslope erosion and channel morphology showed no predictable trend following treatment. Inherent differences in channel morphology between the two watershed prior to treatment existed. This difference may be a product of the two channels being at different evolutionary or successional stages relative to each other and thus indicating that channel recovery would be different for each watershed. The Camp Creek project illustrated that for this system, managing vegetation for water yield may be obtainable at a much lower precipitation threshold than what was previously reported in the literature.

  Citation × Citation Citation Abstract Copy Title: Citizen knowledge and opinions about watershed management in the South Santiam Basin in Oregon Author: Wright, Angela Schaefer Watershed management is widely recognized as an important component of healthy ecosystems and its success depends on cultivating the good will, stewardship values, and participation of citizens. Because much of the streamside land in Oregon is in private ownership activities on public lands will not be enough to protect salmon and restore water quality. Improvements will also depend upon conservation activities by private landowners and communities. Since citizens are an integral part of long-term solutions, understanding the level of knowledge people possess and their opinions about watershed management is essential. This study examines citizen knowledge and opinions about stream management and ecology of the Lower South Santiam River, Crabtree Creek, and Thomas Creek watersheds in the South Santiam River basin. It focuses on the usefulness of various sources of information, public trust in specific information providers, citizens' understanding of watershed ecology, and the problems, preferences and concerns of private landowners. A mail questionnaire and interviews were used to elicit responses from community residents and members of the South Santiam Watershed Council. Several conclusions emerge from the findings. First, most respondents claim to be interested in and concerned about watershed management issues, however, few are well informed about the technical or scientific aspects of watershed ecology and management. Second, respondents indicated they currently receive little useful information about watershed issues, but there are relatively high levels of trust in several information providers. This suggests that an increase or refocus of outreach efforts may be successful in raising citizen awareness and knowledge of watershed issues. Third, most respondents agree that good watershed management is beneficial to both humans and the environment, but are also strongly opposed to various forms of government intervention. Fourth, watershed council members are more knowledgeable about watershed issues and more supportive of conservation and environmental protection. They are also less likely to see government agencies and current policies as problems. These data can assist watershed management agencies and organizations better understand the knowledge, preferences, and concerns of the public. They can also provide a basis for developing ecologically sound and socially acceptable solutions to watershed problems.
