Description

In Greek mythology, Zeus solves the paradox of the giant Teumessian fox, which had the power to never be caught, and Laelaps, the magical hound that always caught its prey, by changing them into constellations (Canis major and Canis minor) where their battle could play out for eternity. Zeus’s paradox also aptly describes the play of politics and science in prioritizing ecosystem recovery actions. Faced with the problem of prioritizing across hundreds of actions identified to recover terrestrial, freshwater, and nearshore domains of the Puget Sound, we structured an interactive process to capture both the key socio-political values of decision makers and expert knowledge about ecological effectiveness. Decision makers identified four important values for prioritization: ecological outcomes, strategic outcomes, protection of tribal treaty rights, and implementation issues. At their direction we decomposed the first two into 27 attributes. Technical experts nominated by decision makers evaluated 74 suites of recovery actions proposed for terrestrial, freshwater, and nearshore ecoystems by the attributes. We used a multi-attribute utility theory model with attribute weights developed with the decision makers to rank the 74 suites of recovery actions. Highest ranked were suites of actions focused on protecting ecosystem structure and functions and on balancing the need to accommodate population growth with ecosystem stressors imposed by development.

The Fox and the Hound: Zeus’s Paradox and Prioritizing Ecosystem Recovery

Room 602-603

In Greek mythology, Zeus solves the paradox of the giant Teumessian fox, which had the power to never be caught, and Laelaps, the magical hound that always caught its prey, by changing them into constellations (Canis major and Canis minor) where their battle could play out for eternity. Zeus’s paradox also aptly describes the play of politics and science in prioritizing ecosystem recovery actions. Faced with the problem of prioritizing across hundreds of actions identified to recover terrestrial, freshwater, and nearshore domains of the Puget Sound, we structured an interactive process to capture both the key socio-political values of decision makers and expert knowledge about ecological effectiveness. Decision makers identified four important values for prioritization: ecological outcomes, strategic outcomes, protection of tribal treaty rights, and implementation issues. At their direction we decomposed the first two into 27 attributes. Technical experts nominated by decision makers evaluated 74 suites of recovery actions proposed for terrestrial, freshwater, and nearshore ecoystems by the attributes. We used a multi-attribute utility theory model with attribute weights developed with the decision makers to rank the 74 suites of recovery actions.
