  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: Phillips Creek Watershed Assessment Abstract -- Watershed Assessments for the Grande Ronde River Subwatersheds are being prepared for the Grande Ronde Model Watershed Program. This Watershed Assessment addresses the Phillips Creek Watershed located near Elgin, Oregon. Phillips Creek is a relatively small watershed (4th order HUC – Hydrologic Unit Classification) containing about 33 square miles or slightly over 24,000 acres. Phillips Creek empties into the Grande Ronde River in Elgin. It is an intermittent stream in some reaches, but water flows year around in other reaches. In this Assessment the main emphasis is on the nonfederal lands. The USDA Forest Service – Umatilla National Forest recently completed a watershed assessment on the National Forest area that includes Phillips, Cabin, Gordon and Dry Creeks. For more complete information on watershed condition on federal lands, please refer to the Umatilla National Forest’s Phillips-Gordon Ecosystem Analysis (PGEA). This assessment will describe the Phillips Creek watershed and help to identify the stream processes and features that are working well, and those that are not. Information that is already available from state and federal agencies as well as from private sources (including people that live in the area) will be used. Several public meetings were held to obtain information and insights from people that live in the area. The assessment will identify human’s positive and negative influences to the immediate stream environment. The assessment should provide enough information to develop project plans and monitoring plans that will help to protect and improve water quality and fish habitat in Phillips Creek and its tributaries. This assessment includes a description of Phillips Creek Watershed, historical conditions assessment, channel habitat type classification, hydrology and water use, riparian assessment, wetlands assessment, sediment sources assessment, channel modification assessment, water quality assessment, water rights assessment, fish and fish habitat assessment, upland conditions assessment – Forest, upland conditions assessment – Range, developed area assessment, noxious weeds assessment, and a watershed condition evaluation.
