Selected Projects

Replacement of Tide Gates Biological Assessment
Client: Skagit County Diking District #22
2006 2008
Summary: Tide gates are an integral component of the dike and drainage management system for agricultural lands on Fir Island, WA. The aging gates require periodic replacement to maintain drainage, prevent flooding and saltwater intrusion, and to minimize impacts to fish populations as a result of fish entrainment. Martin Environment performed biological assessments, conducted project effects analyses, prepared formal BA documents, and assisted in the ESA consultation process for impacts to aquatic listed species for several tide gate replacement projects

Lake Ozette Sockeye Salmon Recovery Plan

Client: Green Crow Timber, Merrill & Ring, and Rayonier Timberland
2006 2008
Summary: Lake Ozette sockeye were listed as a threatened species under the Endangered Species Act (ESA) in 1999.  To restore a population viability, a multiagency/industry group formulated a recovery plan under NOAA guidance.  Martin Environmental convened an expert review panel which performed technical review and editorial comment on the limiting factors analysis and associated population recovery plan documents.  Martin Environmental also participated in planning meetings with the NOAA Technical Recovery Team and assisted in developing biological and watershed management options to facilitate recovery.

Draft Environmental Impact Statement for the Washington State Forest Practices Habitat Conservation Plan
Washington Forest Protection Association
Summary: The state of Washington developed the Forest Practices Habitat Conservation Plan (HCP) in response to the need for recovering populations of federally threatened and endangered fish species. The HCP and associated Forest Practice Act resulted from a multi-stakeholder effort that utilized the best available science to guide the direction of aquatic species protection. Martin Environmental played an important role in performing expert technical reviews of the science underlying the proposed forest practice rules and the environment effects assessment in the draft environmental impacts statement.

Exxon Valdez Oil Spill Effects on Salmonids
1989 1990

Summary: The 1989 Exxon Valdez oil spill in Prince William Sound Alaska was one of the largest oil spills in American history. Immediately following the spill, Exxon contracted with a large team of environmental experts to assess damages on fish, wildlife, and water quality in accordance with the anticipated Natural Resource Damage Assessment. As part of the assessment team, Dr. Douglas Martin (Martin Environmental) lead the initial field investigation to determine the distribution and abundance of juvenile salmonids in oiled and unoiled nearshore waters and examined the toxicity of oil-contaminated areas on the survivability of juvenile salmonids.
