Ecosystem Portfolio Models

A schematic of the South Florida Ecosystem Portfolio Model.  The model evaluates performance of land use plans against multiple management criteria, incorporating economic, ecological, and human well-being submodels.

The Puget Sound Ecosystem Portfolio Model (PSEPM) is a decision support tool that uses land-use change scenarios and a suite of spatially-explicit models to explore the implications of future regional growth and development, including shoreline modifications, to Puget Sound nearshore ecosystems through 2060. The tool currently focuses on threats to barrier and bluff-backed beaches, which represent 50 percent of Puget Sound shorelines by length. A suite of sub-models identify multiple connections between land use and the nearshore’s capacity to support valued ecosystem components (VECs) and ecosystem services. VECs are key elements of the Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) conceptual framework for nearshore restoration, and were selected to communicate the value of Puget Sound nearshore restoration to managers and the public. Ecosystem services are the benefits people obtain from ecosystems including provisioning services such as food and water, regulating services such as flood and disease control, cultural services such as spiritual, recreational, and cultural benefits, and supporting services such as nutrient cycling. PSEPM model outputs include changes in shellfish pollution related to changes in local land-use change, potential shoreline erosion and ecological changes due to local and updrift armoring, and changes in shoreline recreational demand due to changes in population distributions around Puget Sound.

The South Florida Ecosystem Portfolio Model (SFL EPM) is a Geographic Information System-based multi-criteria decision support web tool that evaluates land use plans and proposed land use/land cover (LU/LC) changes in terms of performance criteria related to three dimensions of value: 1) modeled ecological criteria related to ecosystem services, expressed as “ecological value” 2) predicted land market prices and the associated probability of LU/LC conversion, and 3) community quality-of-life indicators. Each of these dimensions is implemented as a sub-model of the EPM that generates “value maps” for a given land use pattern and set of user-elicited preferences, where the value map reflects changes in parcel and landscape attributes. The modeled parcel/landscape attribute changes are related to land use/cover change, including changes in habitat potential and landscape fragmentation, distances to human perceived amenities, community “character”, flooding and hurricane evacuation risks, water quality buffer potential, ecological restoration potential, and other relevant performance criteria. Users can examine the resulting value maps for one or more land use/cover patterns under different weighting schemes, allowing the user to explore how different prioritizations of objectives affects the evaluation process. More broadly, users can also compare ecological value maps, predicted land price maps, maps of community quality-of-life indicators for sets of land use/cover patterns to characterize regional-scale trade-offs between ecological, economic, and social values. By using maps as the means of comparison, local details are retained, while regional patterns emerge.
