  Citation × Citation Citation Abstract Copy Title: MidCoast A - Rapid Bio-assessment 1998 Midcoast Abstract -- Snorkel surveys were conducted in five midcoast watersheds that included the Yachats, Alsea, Yaquina, Siletz, and Salmon Rivers. These surveys were commissioned by the Midcoast Watershed Council, using funds granted by GWEB. The intent of these surveys was to begin to develop a base line for monitoring trends in the distribution and abundance of juvenile Coho, Steelhead and Cutthroat in Midcoast watersheds. Adult Coho escapement for many of these basins has hovered near all time low levels for multiple brood cycles. These surveys intend to identify the core areas within these basins that, at low spawner densities, provide suitable spawning habitats. They also intend to identify areas important for juvenile salmonid rearing such that restoration activities can focus on recovering reaches that adult salmonids are returning to.

  Citation × Citation Citation Abstract Copy Title: Lamprey Abstract -- The majority of scientific studies on lamprey have investigated biological attributes, with few studies investigating historic abundance, detailed distribution and specific ecological requirements and role. Because of the paucity of information and concerns of declining lamprey population in the Pacific Northwest, the Applegate River Watershed Council (ARWC) with the Medford District of the Bureau of Land Management (BLM) collaborated to study lamprey populations in the Applegate River watershed of southwest Oregon (Close et al. 1995, Larson & Belchik 1998, Kostow 2002). The objectives of the study included: (1) Identifying species composition; (2) determining the distribution of lamprey species; and (3) relating the distribution of lamprey ammocoetes (juveniles or larvae) to physical stream characteristics. This paper summarizes the life histories of the two most common lamprey species in the Oregon, the Pacific (Lampetra tridentata) and Western Brook (Lampetra richardsoni), details the methods of study, reports the results and summarizes the findings. Also included are recommendations and suggestions for future lamprey work in the Applegate basin.

  Citation × Citation Citation Abstract Copy Title: Yaquina and Alsea River Basins Estuarine Wetland Site Prioritization Project Final Report Abstract -- The project surveyed estuarine wetland sites in the Alsea and Yaquina basins. Sites surveyed were tidal wetlands falling within Jefferson’s (1975) plant community categories of low silt marsh, low sand marsh, sedge marsh, immature high marsh, and mature high marsh. (Mud flats, algal flats and eelgrass beds were not included.) The goal was to prioritize these tidal wetland sites for protection and restoration activity. The information provided by this study provides a basis for working with interested landowners to develop site-specific action plans. Development of these action plans will require landowner contact, field work, and other steps outlined elsewhere in this report.

  Citation × Citation Citation Abstract Copy Title: Little Deschutes Subbasin Watershed Assessment Abstract -- Many of the impacts to fish and wildlife habitat and water quality in the Little Deschutes River Subbasin are concentrated in the areas of housing, roads, and other human development. Most of the human population in the subbasin is concentrated around the community centers of La Pine, Gilchrist, Crescent, and Crescent Lake. There is significant dispersed development along the lower reaches of the Little Deschutes River between the communities of Sunriver and La Pine -an area characterized by gentle topography and depressions with forested wetlands, marshes and shallow lakes. Streams in this area, as illustrated by the Little Deschutes River , are low gradient and originate in the high elevation areas in the southwest portion of the watershed where there is higher precipitation. This ownership pattern has significant implications for natural resource management, as lower gradient floodplain areas tend to provide important wetland, fish, and wildlife habitat. Key Findings Fuel Loading: Having homes safe from wildfires is a concern for many residents. Fire suppression has increased the amount of dry wood in the area, creating a ready source for major wildfires. Riparian Areas and Wetlands: Loss of wetland and riparian areas , especially in the lower areas along the Little Deschutes River , has affected a number of resources. Water quality has been affected by the reduced wetlands that act as filters of nitrogen; the loss of streamside trees and other vegetation reduces shade that helps to cool water temperatures. Finally, loss ofwetlands and riparian vegetation has reduced important fish and wildlife habitats. Wildlife: The growth and development have altered wildlife habitats. Loss of wetlands, streamside vegetation, and other changes in the watershed have reduced important wildlife habitat. Roads and development have impacted migrating mule deer, increasing collisions between deer and cars and altering their migration pathways. Fish: There has been a significant loss of native trout and an increase in introduced brook and brown trout in the Little Deschutes River and tributaries. Loss of native trout is from competition with introduced species and changes in aquatic habitat and water temperatures. Water Quality: A major concern about the water in the river is unusually high temperatures in the summer and the abnormal growth of algae. Other studies indicated that there are problems with groundwater loading ofnitrogen. The high water table (with associated wetlands), and porous pumice soils contributes to increased nitrates, a by-product of septic systems and an indicator of human pathogens.
