  Citation × Citation Citation Abstract Copy Title: Progress Reports 2004: 2004 Oregon Chub Investigations Abstract -- Oregon chub are endemic to the Willamette River drainage of western Oregon (Markle et al. 1991). This species was formerly distributed throughout the Willamette River Valley (Snyder 1908) in off-channel habitats such as beaver ponds, oxbows, stable backwater sloughs, and flooded marshes. These habitats usually have little or no water flow, have silty and organic substrate, and have an abundance of aquatic vegetation and cover for hiding and spawning. In the last 100 years, off-channel habitats have disappeared because of changes in seasonal flows resulting from the construction of dams throughout the basin, channelization of the Willamette River and its tributaries, and agricultural practices. This loss of habitat combined with the introduction of non-native species to the Willamette Valley resulted in a sharp decline in Oregon chub abundance. The reduction of habitat and the restricted distribution of the Oregon chub resulted in a determination of "endangered" status under the federal endangered species act (Markle and Pearsons 1990; Rhew 1993). To evaluate Oregon chub population abundance and distribution, the Oregon Department of Fish and Wildlife conducted surveys in April-October 2004. We conducted similar surveys in 1991-2003 (Scheerer et. al. 1992; 1993; 1994; 1995; 1996; 1998; 1999; 2000; 2001; 2002; 2003; 2004; Scheerer and Jones 1997). The survey objectives were to collect information on the status, distribution, and abundance of Oregon chub, the presence of non-native and native species, the characteristics of Oregon chub habitats, the characteristics of potential introduction sites, and to evaluate the success of Oregon chub introductions. In addition, we reviewed and evaluated projects and activities with the potential to impact Oregon chub and their habitats and provided summaries to the U.S. Fish and Wildlife Service.

  Citation × Citation Citation Abstract Copy Title: The Status and Trend of Physical Habitat and Rearing Potential in Coho Bearing Streams in the Oregon Coastal Coho Evolutionary Significant Unit Report Number: OPSW-ODFW-2009-5 Abstract -- In 1997, the Oregon Coastal Restoration Initiative (OCSRI 1997) identified the quality of stream habitat as a potential factor influencing the decline of coho salmon (Oncorhynchus kisutch) in Oregon coastal streams. In 1998, the Oregon Department of Fish and Wildlife (ODFW) implemented a monitoring program that utilized a random, spatially balanced survey design to provide statistically rigorous information on the status and trend of habitat conditions in Oregon coastal streams. In response to the ESA listing of coho salmon, the State of Oregon published a comprehensive review of aquatic habitat in the Oregon Coastal Coho Evolutionary Significant Unit (ESU) in 2005 (Rodgers et al 2005). The NOAA Fisheries more recently published a request for additional information in the 2009 Federal Register notice (Federal Register / Vol. 74, No. 81 / Wednesday, April 29, 2009). This report will serve as an update to Rodgers et al (2005), and will provide an analysis of the current status and trends in aquatic habitat from 1998 through 2008 within the Oregon Coastal Coho ESU. The status and trend of instream physical habitat conditions in the Oregon Coastal coho ESU were assessed from twelve variables collected by the ODFW habitat monitoring program from 1998-2008. Habitat conditions were described at the scale of the ESU, four monitoring areas/strata within the ESU, and by six land use categories (agriculture, urban, private non-industrial and industrial forest, and public state and federal forest). The condition of habitat was compared among monitoring areas and land use categories. In addition, the habitat condition at random survey sites was compared to that at sites experiencing minimal human disturbance (i.e. reference sites). Potential winter rearing capacity for juvenile coho salmon was calculated for all available habitat and for high quality habitat at the monitoring area scale and in selected population units. We calculated the rearing potential from high quality habitat because modeling (Nickelson and Lawson 1998) demonstrated that during periods of prolonged poor ocean survival, only areas with high quality habitat will be able to support coho at full seeding during poor marine conditions. The final objective of this report is to discuss whether sufficient habitat capacity exists to support productivity of juvenile coho at the monitoring strata scale during periods of low marine survival.

  Citation × Citation Citation Abstract Copy Title: ODFW Sage Grouse Core Areas Abstract -- Core Area Approach to Habitat Mitigation for Greater Sage-Grouse in Oregon: The goal of these recommendations is to protect essential habitats to meet habitat and population objectives identified in this Plan. The objective of these recommendations is to avoid, minimize, or mitigate for impacts on sage-grouse habitats from energy development, its associated infrastructure or other industrial/commercial developments. The rapid increase in energy development across the West in recent years has initiated a landscape approach to wildlife conservation, referred to as core areas (Doherty et al. 2011). The landscape approach prioritizes habitats based on measures that assess sage-grouse population and habitat relative abundance, and provides protection for a minimum of 75% of the population. The remaining 25% of the population area would be available for development with some level of stipulations and regulations, but likely at a reduced level. The strength of this approach is that it uses biological information to identify core areas with the objective of protecting the most important breeding areas. It also enables managers, at the landscape scale, to map and analyze the risks and necessary conservation measures for each core area. The limitation of this approach is that it focuses on breeding abundances. For sage-grouse the relative abundance data is drawn from spring lek counts of males. Thus, habitat conservation measures may be biased towards breeding and nesting only. Lek data have limitations as well including: variable sampling effort both spatially and temporally and detection probabilities have not been estimated for ground or aerial counts. Notwithstanding, these are the best data available for mapping sage-grouse distributions. Because the method outlined by Doherty et al. (2011) focuses on breeding habitats and ODFWs lek data is prone to variable sampling, an additional and complementary method was used to approximate seasonal use ranges, referred to as connectivity corridors. Using a home range estimator local and seasonal connectivity corridors were estimated. Thus, it is important to clarify some definitions about the mapping approach in Oregon. This document refers to Doherty's "core areas" (i.e., 25, 50, 75, 100%) as lek density strata. Lek density 25-75% polygons and the intersection of 100% strata and local connectivity polygons collectively define a "core area."

Tide gates are tidal flood control structures designed to open and close with each tidal cycle to limit tidal influence on upstream agricultural areas. The basic function of tide gates creates a partial barrier to fish passage. Coastal lowland streams are critical for the sustainability of Oregon Coastal coho, but it is unclear how tide gates may affect coho movement, habitat use and survival. Displaced fishers were employed by the Coos Watershed Association with funding from OWEB Grant 208-2098 during fall 2008 through fall 2009 to assist with implementation of the Life Cycle Monitoring project and related sampling efforts in the lowland coastal subbasins.

  Citation × Citation Citation Abstract Copy Title: AI - Rearing of Juvenile Salmon in Recovering Wetlands of the Salmon River Estuary Abstract -- The Salmon River estuary, on the central Oregon coast, provides an excellent opportunity to study salmonid use of restored tidal marsh. The U.S. Forest Service manages the estuary as part of the Cascade Head Scenic Research Area with the goal to rehabilitate the estuary “to its condition prior to the existing diking and agricultural use.” To achieve this goal, the U.S. Forest Service has completed three dike removal projects at 9-year intervals beginning in 1978. These projects created a patchwork of restored marshes in various stages of recovery, providing a natural laboratory for studying marsh restoration processes and their effects on estuarine rearing salmonids. Our Sea Grant-funded research, which is a cooperative study with researchers from the University of Washington, has four objectives: (1) describe salmon species use of undiked reference and recovering marshes; (2) compare diets of juvenile salmon among reference and diked marshes of different recovery ages; (3) compare availability and distribution of prey organisms consumed by juvenile salmon; and (4) assess geomorphological and ecological indicators (“metrics”) of restored wetlands and relationships to salmon use. This report describes the results of fish distribution and abundance surveys. Results of the other objectives are described in Gray et al. (In Review).
