Development Prototype: Puget Sound Ecosystem Portfolio Model



What is a scenario?
A plausible and often simplified description of how the future may develop, based on a coherent and internally consistent set of assumptions about key driving forces (e.g., rate of technology change, prices) and relationships. Scenarios are neither predictions nor projections and sometimes may be based on a "narrative storyline." Scenarios may include projections but are often based on additional information from other sources (Carpenter et al. 2005).

What are ecosystem services?
The benefits people obtain from ecosystems. These include 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 that maintain the conditions for life on Earth. The concept "ecosystem goods and services" is synonymous with ecosystem services (Carpenter et al. 2005).

What is the Puget Sound nearshore?
The Puget Sound nearshore is defined as that area of marine and estuarine shoreline extending approximately 2,500 miles from the Canadian border, throughout Puget Sound and out the Strait of Juan de Fuca to Neah Bay. It generally extends from the top of shoreline bluffs to the depth offshore where light penetrating the Sound's water falls below a level supporting plant growth, and upstream in estuaries to the head of tidal influence. It includes bluffs, beaches, mudflats, kelp and eelgrass beds, salt marshes, gravel spits, and estuaries (http://www.pugetsoundnearshore.org/what.htm).

What are valued ecosystem components?
"Valued ecosystem components," or VECs, are key elements of the Puget Sound Nearshore Ecosystem Restoration Project (PSNERP) conceptual framework for nearshore restoration. The PSNERP VECs were selected primarily to communicate the value of Puget Sound nearshore restoration to managers and the public, and are intended to speak to ecological and societal values. They embody both economic value and a mix of cultural, spiritual and aesthetic values (http://www.pugetsoundnearshore.org/technical_reports.htm).

Technical Help

Why do I get the wrong data when I click on a location symbol?
Even though symbols may appear to have separation, the clickable area assigned to a symbol can be larger than the image. The best way to ensure you get the right data is to zoom in until you have at least a half an inch separation between symbols

I am unable to click on map features on the Beach Armoring Index page.
To view data associated with the Beach Armoring Index results, first select a subbasin, then click on a feature. This dataset was too large to display all data Sound-wide.

How do I view the .kmz files that I downloaded on the Download page?
The data can be viewed directly in Google Maps by clicking on the map icon next to the file name. Or you can load the data into Google Earth, which can be downloaded for free at http://www.google.com/earth/download/ge/agree.html.
