In addition, the project personnel conducted a snorkeling survey to estimate juvenile salmonid distribution in these streams. The 2006 and 2007 habitat surveys completed the remaining non-surveyed Coho freshwater habitat streams found within the Upper Nehalem. During the 2006 and 2007 seasons we surveyed 218 stream reaches in 87 streams totaling 242.82 kilometers (150.54 miles) of habitat. In addition, the project staff snorkeled 445 pools within the surveyed areas.

  Citation × Citation Citation Abstract Copy Title: AI - Year 2000 Stream Habitat Conditions in Western Oregon Abstract -- The goals of the habitat monitoring portion of the Oregon Plan program are to develop baseline statistics, describe current conditions and track trends in habitat condition over time. This program functions as the landscape link in the overall Oregon Plan monitoring program. Field work for the habitat monitoring program began in 1998 with coordinated site visitations conducted with the two other Oregon Plan monitoring programs; juvenile rearing survey and adult salmon spawning survey programs. The Oregon Plan Habitat Survey program is nested within the Aquatic Inventories Project (AIP). The AIP was begun by the Oregon Department of Fish and Wildlife (ODFW) in 1990 and has expanded to include a wide variety of inventory, modeling and monitoring efforts. The central purpose of these diverse projects is the inventory of physical aspects of the environment that are important for aquatic life and the habitat needs of salmonids and other fishes during the freshwater stages of their life history. Some of the significant ongoing or recently completed projects that are part of the AIP are: Basinwide cesus surveys, Oregon plan Habitat surveys, Restoration Project Monitoring, Salmonid Habitat and Diversity Watersheds Project, Fish Inventories, Great Basin Redband Trout, Oregon Chub Status and Recovery Project, Salmon River Estuary, and Columbia River Estuary Project.

  Citation × Citation Citation Abstract Copy Title: Status of Winter Rearing Habitat In Four Coho Population Units, 2007 Report Number: OPSW-ODFW-2008-7 Abstract -- In a recent assessment of coastal coho salmon by the Oregon Department of Fish and Wildlife (2005), the authors concluded that productivity in 21 of 21 coastal coho populations was limited primarily (13) or secondarily (8) by the complexity of stream habitat used by juvenile coho during their first winter of freshwater residence. The Oregon Coast Coho Conservation Plan (Nicholas 2006), written in response to the assessment, concluded that recovery of coho populations will depend largely on improvement of freshwater habitat. The Conservation Plan (Nicholas 2006) presents population specific goals for the amount and quality of winter habitat needed to achieve desired status of coho populations. Monitoring objectives in the Plan are 1) describe the status of freshwater habitat in each population unit with a focus on features important to overwinter survival of juvenile coho, 2) estimate carrying capacity in each population unit with + 30% confidence, and 3) measure progress towards meeting the habitat goals of the Conservation Plan. This report describes the first two monitoring objectives for winter habitat in four population units: the Coquille, South Umpqua, Siuslaw, and Nehalem. Winter habitat surveys are conducted to describe the freshwater habitat conditions that may limit the survival of juvenile coho during the season at which the conditions are limiting. The Habitat Limiting Factors Model (Nickelson et al. 1992a, Nickelson et al. 1992b, Nickelson 1998) estimates the capacity of streams to support juvenile salmon based on quantitative descriptions of summer and winter habitat. The model assigns value to the size, type and complexity of habitat units, giving highest value to slow water pools such as alcoves and beaver ponds, and pools with large wood. Because winter habitat limits the capacity of most coastal streams to support juvenile coho (Rodgers et al. 2005), accurate estimates of winter habitat are essential to life cycle modeling and to meet objectives of the Conservation Plan. Rodgers et al. (2005) estimated potential carrying capacity of stream habitat within each coastal coho population unit, but statistical confidence was limited by the source and manipulation of the data. Although the data set was extensive, most of the reaches were not randomly selected, and a regression model was used to extrapolate conditions from summer to winter (Rodgers et al. 2005). Summer surveys provide applicable information, but at low flow conditions. Summer weather and stream flows are predictable and conducive to field work; study sites are more accessible, work days are longer and warmer, lower water levels enable walking in the channel more easily, and water clarity is high. However, while more difficult logistically, winter surveys provide estimates during high flow conditions thought to be most important to juvenile coho survival. The winter surveys are conducted during “base flow” when off-channel habitats and secondary channels are inundated, but not over floodplain. The winter 2007 survey sites were selected using the Generalized Random Tessellation Stratified (GRTS) sample design (Stevens 2002) from a pool of sites previously surveyed during summer. This provided an opportunity to describe status within coho population units and refine the summer to winter conversion regression model. More sites are visited during summer than winter, and the sample pool will expand if we can use summer surveys to predict winter conditions. A thorough description of seasonal habitat variation will determine the appropriateness of using summer habitat data to assess habitat conditions during the winter. The objectives of this report are to provide the status of winter habitat surveyed in 2007 in four Oregon coastal coho salmon (Oncorhynchus kisutch) population units (Nehalem, Siuslaw, Coquille, South Umpqua), estimate the potential winter capacity of streams within those population units, and describe the differences observed in stream habitat between winter and summer with emphasis on slow water and secondary channel habitats. We also performed a sensitivity analysis to determine the number of survey sites necessary to represent each population unit within the desired confidence recommended in the Conservation Plan (Nicholas 2006).
