Mathematical Biology and System Monitoring Projects

Monitoring

• Integrated Status and Effectiveness Monitoring Program (ISEMP)

  Project lead: Chris Jordan
  This project seeks to design, implement, test, and evaluate Status and Trends and Effectiveness Monitoring programs for salmon and steelhead populations and habitat. ISEMP pilot projects are being developed in the John Day, Salmon and Wenatchee basins of the Interior Columbia. In addition to monitoring salmon and steelhead populations and habitat within pilot basins, ISEMP is designed to test the robustness of monitoring protocols, indicator metrics, and sampling designs currently used in monitoring programs. ISEMP plans to develop tools to facilitate effective data analysis, management and communication.

• Pacific Northwest salmon habitat restoration project tracking database

  Project leads: Stephen L. Katz, Katie Barnas
  The database currently contains spatially referenced, project-level data on over 23,000 restoration actions initiated at over 35,000 locations in the last 15 years (98% of projects report start or end dates in the last 15 years) in the states of Washington, Oregon, Idaho and Montana, USA.

Risk Assessment

• Development of extinction estimation methods for noisy time series data

  Project lead: Eli Holmes
  This project focuses on stochastic estimation for population processes with the purpose of estimating extinction probabilities and similar risk metrics.

• Risk Assessments

  Project lead: Eli Holmes
  Risk assessments for endangered and threatened species

• Historical changes in Steller sea lion demographics in the Bering Sea

  Project lead: Eli Holmes
  This project is in collaboration with the National Marine Mammal Laboratory and uses monitoring data over the last 30 years to study changes in survivorship and fecundity of Steller sea lions in the Bering sea.
