Our current projects support a wide range of activities and industries, including commercial, recreational and subsistence fisheries management, threatened and endangered species recovery, habitat restoration design and effectiveness monitoring, resource development, FERC relicensing, project permitting and compliance, adaptive management planning and conservation planning.  The following is a snapshot of some of the skills and qualifications our staff possess. This list is not exhaustive, and we're always looking to expand our project base with novel and emerging methods, so if you have ideas and think we might be able to help, don't hesitate to contact us.
