Oregon Steelhead Status, Recovery Planning and Monitoring Kevin Goodson Oregon Department of Fish and Wildlife Pacific Coast Steelhead Management Meeting March 4, 2008
2
Outline Review status assessments from 2005 Review status assessments from recovery planning efforts in the Mid-Columbia, Lower Columbia, Upper Willamette and Snake DPSs Describe monitoring efforts for steelhead in Oregon
3
2005 Oregon Native Fish Status Report Last formal assessment for many management units Shared at 2006 steelhead management meeting Snapshot of current status, not assessment of extinction risk Status not believed to have changed significantly

Mid-Columbia Recovery Scenario for each MPG One half of historic populations Proportional size representation All life histories represented One population highly viable All populations not viable should be maintained
12
Cascades Eastern Slope Tributaries MPG Recovery Scenario Fifteenmile Creek: winter run and basic size Deschutes Rv Eastside: summer run and intermediate size Deschutes Rv Westside: summer run and large size Klickitat River: winter/summer run and intermediate size Rock Creek maintained
13
John Day River MPG Recovery Scenario Lower Mainstem John Day: very large size North Fork John Day: large size Middle Fork or Upper John Day: intermediate size South Fork maintained
14
Umatilla/Walla Walla Rivers MPG Recovery Scenario Umatilla River: only large size available Walla Walla River or Touchet River: intermediate size

24
Oregon Monitoring Efforts Slowly adding to annual efforts for steelhead Some data from efforts for coho Most surveys utilize probabilistic sampling In addition to dam/trap counts, and other basin-specific efforts Recovery and conservation plans will identify additional monitoring needs
25
Steelhead Spawning Surveys Currently conducted in Klamath Mountains Province (KMP) and Oregon Coast DPSs along with the John Day Basin Counting and marking redds Useful to examine abundance, productivity and spatial structure Currently estimating DPS abundance
26
Coastal STW Spawning Trends
27
Western Oregon Rearing Project Summer juvenile snorkel surveys Only in pool habitat and within coho distribution Currently conducting surveys in KMP, Oregon Coast and Lower Columbia DPSs Provides trend information on densities and distribution
29
Aquatic Habitat Inventory Surveys Conducted in the KMP, Oregon Coast and Lower Columbia DPSs Surveys inventory multiple habitat components Will provide ability to track changes with reasonable sensitivity
30
Summary Current status in most non-listed management units in Oregon appears stable Oregon is working hard to develop conservation/recovery plans Securing funding to continue and increase monitoring is a priority
