Understand how landscape integrity supports ecosystem funcgons, which, in turn, delivers nature's benefits to the community. 2
Understand how landscape integrity supports ecosystem funcgons, which, in turn, delivers nature's benefits to the community. 3
Develop and test an ecosystem service- based analygcal framework, deployed at the watershed and regional scale, to help guide open space investment and governance decisions and to support cross- jurisdicgonal collaboragon. 4
Ecosystem Services as Component of Overall Strategy analysis decision making ac.on
analysis decision making ecosystem valua.on framework engagement with ROSS tool for partners
Goals Development of a high level tool to inform decision makers on poten.al values of ecosystem services Provide rela.ve weights of ecosystem services of different landscape types Applicable at the watershed and regional scale Methods supported and endorsed by technical experts and decision making community

Tool Application of past primary valuation studies Function transfer NAIS Brief description Application of valuation data directly from past primary valuation studies, when available for the study site Value transfer from policy site to study site without accounting for ecological and socioeconomic context Value transfer from policy site to study site that accounts for ecological and socioeconomic context via classical multiple regression Value transfer from policy site to study site that accounts for ecological and socioeconomic context by use of Bayesian multiple regression changes in ecosystem services Open-source ecosystem service mapping and valuation models run using ArcGIS web tool under development Open-source dynamic modeling system for mapping and valuing ecosystem services preferences services using focus groups types for point transfer Valuation database paired with GIS mapping of land-cover types for point transfer ArcGIS toolbar for mapping social values for ecosystem services based on survey data or value transfer Tested in this study?
