  • Summary

    Cooperation is an important way that decision centres interact in a polycentric governance system. Cooperation in governance has been studied by numerous scholars in the field of 'collaboration', although such scholarship seldom explicitly sets it within the framework of polycentricity. Cooperation involves multiple decision centres working across boundaries to pursue shared goals, and it is especially prevalent for addressing complex socio-ecological systems. This chapter examines cooperation in the Puget Sound basin, USA, for ecosystem restoration. This chapter describes how authority, information, and resources affected cooperation in formation of the Puget Sound Partnership and related Local Integrating Organizations, development of ecosystem recovery plans, and implementation of ecosystem recovery projects. It assesses polycentric governance performance in terms of outcomes and processes. The Puget Sound ecosystem restoration efforts exhibit relatively high levels of coherence, representation, and adaptability; relatively low levels of efficiency and accountability; and mixed results on efficacy and network building.

  • Long-term retreat rates of Puget Sound's unconsolidated sediment shorelines have been difficult to quantify, and little systematic research has been completed to constrain retreat in this area. We put forward a new application of cosmogenic 10Be exposure dating to assess long-term shoreline retreat on Whidbey Island, WA by dating lag boulders exposed on the shore platform as the shoreline erodes. Production of 10Be in shoreline boulders is modulated by both tidal submergence and topographic shielding from the retreating bluff. By modeling the combined effect of these variables on 10Be production, the timing of exposure can be determined and used to calculate long-term (103–104 yr) bluff retreat rates. In rare cases, retreat rates are underestimated due to inherited 10Be. Within the study area, average retreat rates ranged between 0 and 8 cm yr− 1. Our results demonstrate the utility of cosmogenic nuclides for determining long-term shoreline retreat rates in areas with thick sediment cover, where large numbers of samples can be collected, and where the pre-depositional history of the boulders is uncomplicated.
