Working Group 36: Common Ecosystem Reference Points across PICES Member Countries
Terms of Reference
  1. Outline each country’s mission, goals, and governmental science plans that point to the establishment of reference points across PICES member nations, and identify those that are comparable. (Intersessional / Yr1)
  2. Summarize previous efforts identifying data availability for geographic areas and time periods of particularly strong climate influence and dependence on marine systems within specific North Pacific ecosystems, fish stocks, and fishing communities. This will build upon indicators identified via WG-19, WG-28, S-HD and WG-35 (NPESR-3). Determine a subset (or not) of ecosystems and indicators that will be the focus of WG activities. (Intersessional / Yr 1)
  3. Summarize and select previous methods for determining thresholds (both non-linear and societal limits) in ecosystem indicators. This would include statistical and objective-based approaches (Intersessional / Yr 1)
  4. Determine shapes or functional forms of driver - response relationships from available datasets, and quantify thresholds to identify potential ecosystem reference points. (Yr 2)
  5. Identify ecosystem components that respond earliest to changes in biophysical drivers and could potentially serve as leading indicators of loss of resilience and ecosystem change. (Yr 3)
  6. Develop a “heuristic model” to examine drivers (climate forcing, fishing) and ecosystem response using selected ecosystem reference points for member nations. (Yr 3)
  7. Publish final report.
