USEPA, Western Ecology Division Corvallis, OR USA Developing Ecosystem Services Science for Policy Needs in the Willamette Basin, Oregon, USA:A Place-Based Study Linking Human Well-Being with Ecosystem Services ACES Meeting – Naples, FL 09 Dec 2008
The EPA Challenge: Change the economic and human well-being foundation for environmental decision-making Current Investment: 200 Scientists ~$62 million dollars supporting research
Ecological Services Research Program Goals: • Long-Term Goal 1: National policy makers will have the tools and technologies to develop scientifically-defensible assessments of the state of our nation’s ecosystems and the effectiveness of existing national programs and policies • Long-Term Goal2: States and tribes apply improved tools and methods to protect and restore their valued ecological resources • Long-Term Goal 3: Decision-makers understand the importance of ecosystem services and make informed, proactive management decisions that consider a range of alternative outcomes
Uses • Setting policies and guidelines: • EPA often seeks to promote its mission through a variety of policy instruments that do not have the legal force of national rules. . • Quantifying benefits for national rule-making: • The Office of Management and Budget establishes data requirements needed to assess the benefits and costs associated with these rules. • Developing environmental GDP accounts or other environmental indicators: • In recent years, there have been numerous calls for establishing environmental accounts within our national Gross Domestic Product accounts. • Acting as a catalyst for market innovations: • In some cases, EPA seeks to engage the private sector directly in its efforts to improve environmental conditions.
EPA Ecological Services Research Program - Place-Based Studies Southwest
Why Place-Based Research? • Work with actual, interested end-point users of research tools to assist with design and implementation • Confront contextual social and economic forces, challenges and solutions • Test models with appropriate data types and coverages • Develop a manageable approach to scaling • Enlist “local” experts with knowledge tailored to the question and issues • Compare like and contrast different approaches to similar issues among PBPs • Synthesize knowledge derived from the above activities to determine what level of information is ADEQUATE for decision makers to project ES at a national scale.
65% Forest 20% Ag; 11% Urban 4% Riparian Wetland Not all forests are equal High elevation (N sensitive or N retentive?) Broadleaf vs. Conifer Willamette Ecosystem Service District Portland, OR Landcover
CLIMATE OF OPPORTUNITY Why the Willamette? • Willamette “Ecosystem Service District” provides a broad range of Land-Use/Land-Cover, stressors, gradients, and diverse, linked settings • WED Alternative Futures research experience (mid 1990’s) = rich data sets, experienced researchers, potential collaborators (NRCS, USACE, USDA-FS, USGS, OWOW, etc.) • Well Connected Research and Regulatory Entities now Working toward future Ecosystem Service trading (Region X) • Multiple related Star Grant recipients (OSU, OU, PSU) • Willamette Partnership (State Non-Profit); OWEB • Trading Scenario for Temperature (riparian wetland ecosystem service) rapidly developing – EPA Funding with Region X oversight • ORD Multi-Year Plan – Ecosystem Research Program: provides explicit context
Overall Goal:The W-ESP seeks to provide a scientifically based decision support system for valuing and projecting ecological services resulting from alternative management decisions Objectives:Quantify ecosystem services, including their distribution and status. Provide models to predict responses of ecosystem services to probable future conditions.Identify critical knowledge gaps in our understanding of how ecosystem services are provided.Evaluate net benefits of bundled ecosystem services and tradeoffs among management actions that affect these services.

Definition of Terms Used to Determine Future Responses of Ecosystem Services toMultiple Response Variables • Forcing Variables (Stressors) • Natural and anthropogenic factors affecting quantifiable changes in the status (e.g. amounts & fluxes) of ecosystem processes • ERF: Ecological Response Function • The response of an ecosystem service to a particular forcing variable • ETF: Ecological Trade-off Function • The relationships between two (or more) ecosystem services in response to the same forcing variable (…and, eventually, multiple forcing variables)
Conceptual Framework Ecosystem Service vs. Forcing Variable = ERF ERF1 ERF2 Crop Yield N Export N Fertilization N Fertilization • ERF Y-axis: Ecosystem Services • Food/fiber Yield • Carbon Sequestration • Water Quality • Water Quantity • GHG regulation (N2O, NOx, CH4 …) • ERF X-axis: Forcing Variables • Soils & Geology • Climate (Temp, Precip, Light, CO2) • Fertilization Practices • Tillage Practices • Cover Type (Species, Riparian Buffers…) • Many others… ERF1 + ERF2 Tradeoff = ETF Yield Crop Yield N Export N Export N Fertilization Socioeconomics Valuation & Trading of Ecosystem Services

Develop an approach to inventory and map ES Inventory and mapping the location and value of Ecosystem Services is an essential activity of W-ESP W-ESP (Chan et al. 2006)
