The South Florida Ecosystem Portfolio Model
There are intense development pressures in the lands outside of the Urban Development Boundary in Miami-Dade
County, Florida, impacting both the Everglades and Biscayne National Parks. The Ecosystem Portfolio Model is
a web tool that uses integrated ecological, economic, and social information to allow stakeholders to evaluate
future land use/cover scenarios in terms of relevant indicators.

Integrated Landscape Monitoring (ILM) Program: Integrating the Human Dimension
We are living in a period of unprecedented environmental change. Determining the impacts of human actions on
natural processes and predicting their effects is critical to ensuring a sustainable future for all,
both economically and ecologically. Monitoring change at the landscape level provides a window to
view ecosystem responses that could not be detected at the small site scale. The USGS ILM project
harnesses the talents of scientists of from all the USGS disciplines to better understand and respond
to ecosystem change.

National Ecosystem Mapping
The United States lacks a standardized coast-to-coast ecosystem map at an appropriate scale for local
on-the-ground management The classification and delineation of ecosystems is fundamental to managing ecosystems.
To address this need, USGS ecosystem mapping program is synthesizing abiotic and biotic features, landforms,
surficial geology, bioclimatic zones and vegetation to delineate ecosystem units with 30-meter resolution.
In addition to the final map product and a better understanding of the evolution of ecosystems, the individual
abiotic map products will become available for the first time, e.g. Digital Landform, Surficial Geology, and
Bioclimatic Zone Maps of the Conterminous U.S.

Benchmarking External Efforts and Organizations to Improve the Use of Science by Decisionmakers
This project focused on identifying the efforts of organizations external to the U.S. Geological Survey
(USGS) that focus on improving the use of science to support societal decisionmaking. This information was
collected to provide the USGS with additional program ideas and potential avenues for collaboration to
improve the use of science by society.

The Land Use Portfolio Model
Western Region Geography has developed the Land Use Portfolio Model (LUPM), a tool for modeling,
mapping, and communicating risk. It is designed to help public agencies and communities
understand and reduce their vulnerability to, and risk of, natural hazards. The LUPM is adapted
from financial-portfolio theory, a method for evaluating alternative, regional-scale investment
possibilities on the basis of their estimated distributions of risk and return.

Monitoring Colonias Development Along the United States-Mexico Border
The Colonias Monitoring Program provides a publicly accessible, binational, GIS database to
enable civic leaders and citizens to inventory, analyze, and monitor growth, housing, and
infrastructure in border communities. High-technology tools are provided to support planning
efforts and development along the border, using a sustainable and comprehensive approach. The
collective information can be used by nongovernmental organizations in preparing grant and
loan applications for community-improvement projects. more...
