National Ecosystem Services Classification System (NESCS) Plus: Case Studies

The National Ecosystems Classification System-Plus (NESCS Plus, pronounced “nex-us plus”) is a robust, step-by-step resource for tracing the links between natural ecosystems and human well-being.

Below are some examples of recent publications that use components of NESCS Plus.

Piloting Ecosystem Accounts for the Southeastern U.S.

Coins stacked in soil with plants on top to symbolize environmental accounting.EPA researcher Marc Russell and his collaborators have used NESCS Plus in the first effort to develop Ecosystem Accounts for the U.S. at a broad scale. The team has explored the potential for U.S. ecosystem accounting and explain their pilot accounts for a 10-state region in the Southeast. The pilot accounts address air quality, water quality, biodiversity, carbon storage, recreation, and pollination for selected years from 2001 to 2015. In their study, Testing ecosystem accounting in the United States: A case study for the Southeast, they explain how results can contribute to policy and decision making. For example, in Atlanta they show how ecosystem accounts can help give a more complete picture of a local area’s environmental-economic trends.

Photo by Eric VanceEPA Researcher Paul Ringold and his postdoc Arik Tashie searched the EPA’s EnviroAtlas for useful metrics for Final Ecosystem Goods and Services.  They selected the EnviroAtlas because it contains a large fraction of the existing ecological data that is available at a national scale. The researchers investigated linkages between NESCS Plus Environment and Beneficiary classifications and EnviroAtlas data layers. In A critical assessment of available ecosystem services data according to the Final Ecosystem Goods and Services framework, they created a database of over 14,000 linkages between 255 EnviroAtlas data layers.  These linkages were classified as intermediate ecosystem goods and services, final ecosystem goods and services, and social or economic outcomes.

Who Benefits from National Estuaries? Using an Ecosystem Services Classification System to Identify Beneficiaries

People enjoying nature and walking along a boardwalk at Mobile Bay National Estuary in Mobile, Alabama.EPA researchers conducted a document analysis of national estuary management plans using the final ecosystem goods and services (FEGS) Classification System (recently updated as NESCS Plus). In Who Benefits from National Estuaries? Applying the FEGS Classification System to Identify Ecosystem Services and their Beneficiaries, they present a suite of ecosystem services relevant to management of National Estuary Programs (NEP) and the National Estuarine Research Reserve System (NERRS), and explicitly link them to the beneficiaries who use them.

Who Benefits from Coastal Habitats?

Cody Fonseca, Laforche, LA, sets out for a day of crabbing. USEPA photo by Eric VanceTo support coastal communities in land-use planning and prioritization efforts, university scientists and EPA researchers, Theodore DeWitt and Matthew Harwell, examined the state of the science for final ecosystem goods and services (FEGS) in coastal ecosystems. They reviewed ~2,800 studies and documented how various human beneficiaries rely on coastal habitats in Linking people to coastal habitats: A meta-analysis of final ecosystem goods and services on the coast. Recreational (83%) and industrial (35%) users were most cited in literature, with experiential-users/hikers and commercial fishermen most prominent in each category, respectively. This work highlights the intricate relationship between healthy coastal environments and the socio-economic systems they support. The authors hope communities and other stakeholders will couple results from this study with other tools, such as EPA’s EnviroAtlas, to recognize and protect existing FEGS, and plan for future ecosystem service delivery.

How does air pollution impact ecosystem services?

In Joshua Tree National Park, a desert area in southern California, nitrogen deposition has caused non-native grasses to increase so much that they can now carry fire across some parts of the landscape.ORD researchers, Dixon Landers, Amanda Nahlik, and Chris Clark, worked together with a team including EPA’s Office of Air and Radiation and Office of Water in a workshop to introduce the STEPS (Stressor–Ecological Production function–final ecosystem Services) Framework, a novel way to apply FEGS-CS as the foundation for identifying difficult and unknown linkages between humans and components of the environment that may lead to human well-being. In A framework to quantify the strength of ecological links between an environmental stressor and final ecosystem services, the examine the ecological impacts of nitrogen and sulfur pollutant emissions and deposition to changes in final ecosystem services. This application is a means of defining a common approach to identify the potential beneficiaries and possible metrics and indicators.

Improving the Linkage between Biophysical and Economic Analyses

Conceptual model for Adaptive Management from Boyd et al. 2016

A team of natural and social scientists examined the ways in which ecosystems link to human wellbeing and the way biophysical metrics and indicators should be defined to strengthen that linkage. The paper develops principles to guide the identification of Final Ecosystem Goods and Services (which it refers to as linking indicators); compares their features with those of more commonly collected primarily from the point of view of conducting monetary valuation of ecological outcomes ecological measures; and reviews empirical evidence pertinent to their identification, definition, and performance. The work is divided into several sections. The first is an introduction to the issue. Section 2 of the paper articulates two broad goals that the team argues can help frame the identification of linking indicators. The more obvious of these is the desire for biophysical outcomes that lay audiences can relate clearly to their own well-being. The second goal is to choose indicators that enhance the accuracy of social evaluations. We show how both goals are related to the concept of ecological production. Section 3 describes the deployment of linking indicators in various policy applications. Section 4 identifies research questions pertinent to identification and evaluation of linking indicators and reviews pertinent existing research. Section 5 summarizes the primary findings of the evaluation and offers recommendations for indicator development. This strategy should facilitate collaboration between natural and social scientists; improved understanding, specification, and measurement of linking indicators; and more accurate and powerful environmental policy analysis.

What Data Should We Collect?

Crop irrigation in Idaho. In 2005, 247 000 km2 of land were irrigated in the US. Just under half was irrigated with sprinklers, one type of which is shown in this figure, with the remainder irrigated by flooding (44%) or micro-irrigation

A team of natural and social scientists applied the Final Ecosystem Goods and Services (FEGS) framework to identify metrics and indicators to link changes in policies to changes in human well-being when that linkage is mediated by ecosystems. The six-step process presented enabled the authors to propose metrics associated with streams that can be used in the analysis of human well-being. The team illustrates these steps with data from a regional stream survey. Continued refinement and application of this framework will require ongoing collaboration between natural and social scientists. Application of this framework could result in more useful and relevant data, leading to more informed decisions in the management of ecosystems.
