Background
Ecosystem services (ESs) represent an ecosystem's
capacity for satisfying essential human needs, directly
or indirectly, above that required to maintain ecosystem
integrity (structure, function and processes). The spatial
characterization and mapping of ESs is an essential first
step in establishing existing conditions to characterize,
assess, value and communicate the impact of decisions
that affect ESs and the benefits that flow to society.
The US Environmental Protection Agency, as part of
the Ecosystem Services Research Program, has a goal
of developing a National Atlas of Ecosystem Services,
thus we conducted an intensive literature survey related
to characterizing and mapping ecosystem functions,
processes, and services. We reviewed over 250 journal
articles dating from 1990 to 2009. The number of
articles on ecosystem services and related functions and
processes has increased exponentially since 1990.
Information on ecosystem services were summarized
from the literature and assigned to general ESs classes
as shown in Table 1. This literature database hereafter
will be referred as the characterization and mapping of
ecosystem services (CMESs) database. The CMESs
Database was developed to aid the Landscape Ecology
Branch in sorting through the ever increasing amount of
data specific to mapping ecosystem services and is
available to the public.
The following notes detail the construction of the
database including keywords that were searched as part
of this effort, a brief description of the data fields, and a
description of how to access and use the database by
adding records or viewing and printing pre-packed
report forms.

Pre-defined searches
We developed and include in the database several pre-
defined reports that were found to be most useful to the
current database users; they include summary reports
by individual journal article and by:
•	Study Area(s)
•	Primary- ecosystem
•	Types of models
•	Report year
•	General spatial scale (study area extent)
•	Number and type of ecosystem services
•	Summary by ecosystem services
Accessing and Using the Database
The database base was originally developed in Microsoft® Excel
97-2003 Worksheet and imported to Microsoft Access 2003. The
Microsoft Access Tables, Queries, Forms, Report, Macros and
Modules were created in Microsoft Access 2003. It was migrated
to Microsoft Office Access 2007 SP2 MSO. It uses the
Microsoft Office Access Database (.mdb) that has not been
converted to the new Access file format (.accdb). Accessing the
database can be done from the CD itself or from your PC (after
saving it on your personal computer). To make database
changes, you will have to copy the database to your PC.
*Note: page layout will be different
between versions of Microsoft Office
Access.
Create a folder named CMES and copy
the files on the CD into it. Double
clicking on the "Start" button with the
Explorer icon will get you to the front
page of the database (Figure 1).

Forest buffer strips are widely recommended for trapping nonpoint-source pollutants and
protecting surface water quality, yeet few models are designed to identify key areas for
buffer installation and management. This artide presents a conceptual model of polluted
runoff dynamics to provide traction in estimating watershed-wide forest buffer needs.
Inputs required for these estimates include elevation and land-cover maps, along with
derived products that represent basic nutrient runoff principles.

Printing and Displaying Reports
The Display Reports Form button (Figure 10) takes you to a series of printable forms. The forms can be printed by
individual journal article or summarized by article ID. Summaries of data collected from individual journal articles
are available on three separate forms (Scale and Ecosystem; Journal Information, or Ecosystem Services). You must
input the ID number of the article in the database you want to print on each of the forms that correspond to data you
wish to print. To exit the form ;

return to the selectable forms page simply hit the close window button in the
To exit the selectable forms page and return to first page of the database, again simply hit the close window button

The following information can be summarized: the number of articles by journal, location of research, publication
year, ecosystem services and research scales (Figure 11). When any one of these forms is selected you must type in
the project code twice before the form is completed; once to call up the table and once to create the histogram.
Additionally, by right clicking your mouse on the figure and selecting export, you are able to export the summarized
data to several different formats including Excel.
The next set of forms (third column of fonns) is similar to the second and summarizes data in the entire database;
therefore you do not have to enter a project code for these forms.
The wetland report in the next column will list the articles where wetlands were the primary ecosystem after
selecting a project code. This report lists the ID numbers and basic reference information for the articles so the
wetlands data in the database can be found and printed easily.

Database Fields and Their Definitions
The database was developed in Access 2003 and includes the following data fields:
•	Project Code - Provided for LEB internal use, however users have the ability to add their own codes
•	Brief comment
•	LEB Reference Number - Relates specifically to documents being prepared by the Landscape Ecology Branch
•	Short Reference - Primary authors and year of publication
•	Year - Year of publication
•	Journal - Journal that the article appears in
•	Area - The location(s) of project sites studied by the authors
•	Spatial Scale - The spatial extent(s) of project sites studied by the authors. If known, the spatial extent is given
in km2
•	Temporal Scale - The temporal duration of the studies conducted by the authors. If known, the temporal
duration is given in years.
•	General Scale- The articles were grouped based on the generalized extent of a projects area. The general scales
are defined as follows:
o Local -A single basin or less and include multiple watersheds, urban areas, islands, and households
etc.
o Subregional - More than one basin.
o Regional - Areas with common biophysical characteristics (e.g., Midwest corn belt, Atlantic Coastal
Plain).
o SubNational - Large areas covering at least 1/3 of the nation.
o National - Country-wide or for the United States, covering at least the lower 48 states or continental
US (CONUS).
o Continental - North America, South America, Asia, Europe, etc.
o Global - The entire planet.
•	Primary ecosystem addressed - An ecosystem was the primary research target. However, few ecosystems are
studied without an understanding of their relationship to other ecosystems.
•	Other ecosystems addressed - Ecosystems that were of secondary importance in the study. In some cases where
land cover was the target and the researcher did not explicitly establish all of the various cover types, they were
regarded as multiple ecosystems only.
•	Ecosystem Services - The services that were the focus of the research by the authors. We included biodiversity
and habitat as well as several quality of life indicators (Table 1). Although several services can be placed into
more than one class, we selected one class for each ecosystem service, based on our expert judgment, in order to
summarize the data. For example, waterfowl production could be either a provisioning/supporting or cultural
service. Although waterfowl production is managed primarily for recreational purposes (hunting and bird
watching), waterfowl may also provide food for subsistence and support biodiversity and ecosystem integrity.
Because waterfowl production supports recreation, we felt it played more supporting roles and so placed it in
the supporting class. The characterization of a service depends both on semantics and individual research goals.
Our original list of services also included quality of life (QOL) indicators summed as a group. We eliminated
this service and placed all of the QOL indicators under the cultural class of services. The QOL indicators are
identified in Table 1 with an asterisk. Users can reclassify services in the database.
•	Primary Tools - We grouped the primary tools used to study ecosystem services into six major categories;
geospatial models, neutral models, process models, statistical models, land cover change models, or climate
change models, and further identified where models were used for development of future scenarios.
The United States Environmental Protection Agency, through its Office of Research and Development, funded this
research. The work has been subjected to Agency review and approved for publication. Approval does not signify
that the contents reflect the views of the Agency, nor does mention of trade names or commercial products constitute
endorsement or recommendation for use.
