Section 7 Consultaton - Technical Assistance and Guidance


Bull Trout -
Protocols and standards for fish exclusion, capture, handling, and relocation where conducted within the range of the federally listed as threatened bull trout. Electroshocking guidelines and references are also included in this document. (pdf)
Criteria for Injury to Marbled Murrelets from Underwater Sound Resulting from Impact Pile Driving of Steel Piles -
Recommendations of expert panel which were adopted by the U.S. Fish and Wildlife Service. Establishes the sound exposure level (SEL) of 202 dB be used to identify onset of injury (as indicated by hair cell loss in the inner ear). As a further refinement, an SEL of 208 dB can be used to identify the point at which those injuries would likely include more severe injuries referred to as barotraumas. These criteria do not address temporary hearing effects that occur without actual damage to the inner ear, nor do they address effects to behavior.
Monitoring for Marbled Murrelet Presence -
The Washington Fish and Wildlife Office has developed a protocol for monitoring for marbled murrelet presence during marine pile driving projects that create sound levels which may harm or harass this threatened species. Use of this protocol is sometimes required through the Endangered Species Act Section 7 Consultation process. Monitoring must be conducted by monitoring staff that are certified through our training program. A list of certified monitors can be found here. For more information, contact Emily Teachout at emily_teachout@fws.gov.

Marbled Murrelet Nesting Season -
This analysis of best available science modifies our dates for the marbled murrelet nesting season. It also reviews new information related to timing of feeding of chicks and provides guidance for evaluating and avoiding effects to nesting marbled murrelets. (pdf)
Sediment -
Guidance on evaluating effects to bull trout from sediment-generating projects. (pdf)
Stormwater -
Joint Agreement with Federal Highway Administration, Washington Department of Transportation, US Fish and Wildlife Service and National Marine Fisheries Service and Technical Guidance on evaluating stormwater effects on listed salmonids for transportation projects in Washington
