We propose to support the revision and implementation of the South Atlantic Landscape Conservation Cooperative’s Conservation Blueprint by integrating its Ecosystem Indicators into a structured decision support system that makes explicit how the Indicators are interrelated and how these will respond to management and policy interventions aimed at improving the conservation status of the South Atlantic region. Our specific objectives are to (1) develop ecological production functions that predict theecological impacts of selected conservation actions relative to current conditions, and to propagate these impacts through other affected systems or functions; (2) codify protocols for updating and curating geospatial...

We will develop SMART-SLEUTH, an advanced spatially explicit modeling framework designed to augment the current SLEUTH model with sophisticated smart-growth capabilities. Based on the latest version of SLEUTH, we will create an open-source GIS-enabled software package that will implement SMART-SLEUTH with advanced modules and tools for evaluating, predicting, and visualizing smart growth scenarios and outcomes. In this software package, a more user friendly Graphic User Interface (GUI), a multi-level automatic calibration approach built on machine learning algorithms, and new spatial landscape metrics for quantifying land change patterns will provide enhanced support for complex model configuration, calibration,...

Our project focuses on understanding patterns and causes of recent population declines in the Haleakala silversword that are associated with decreasing precipitation, increasing temperature, and related climate changes in Hawaii’s high-elevation ecosystems. The Haleakala silversword is an ideal taxon with which to assess impacts from climate change. It forms the foundation of a diverse alpine community and likely reflects wider ecological changes; it is already exhibiting patterns of mortality consistent with an upslope shifting distribution; and its high visibility and symbolic status make it unmatched in educational potential. Building on extensive research infrastructure, we propose to collect the demographic...

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide testable...

This map shows the current and historic distribution of this ecosystem, in the context of change agents and disturbance types, as well as current and near-term status and long term potential for change. This map includes current distribution from NatureServe Landcover (type not mapped separately from PJ Woodland in LANDFIRE EVT), and historic distribution from LANDFIRE BpS.

This data release comprises nearly three decades of measurements of sandbar topography for monitoring sites along the Colorado River in Grand Canyon National Park and Glen Canyon National Recreation Area. The data were collected to monitor the effects of the operations of Glen Canyon Dam on sandbars, which are also recreational campsites. The data were collected by the US Geological Survey Grand Canyon Monitoring and Research Center in cooperation with Northern Arizona University. Funding for data collection, processing, and reporting has been provided by the Glen Canyon Dam Adaptive Management Program administered by the US Department of the Interior Bureau of Reclamation.
The Gap Analysis Project (GAP) Analytical Database represents a synthesis of three core datasets for the conterminous U.S. Specifically 1) the GAP/LANDFIRE National Terrestrial Ecosystems_2011; 2) the Protected Areas Database of the United States (PAD-US) 1.4; and 3) the Species Ranges and Habitat Distribution Models for all terrestrial vertebrates. This database provides a mechanism to effiiently obtain summary statistics of those for a variety of spatial extents, including US states, US counties, Landscape Conservation Cooperation Network Areas, EPA's Level III-IV Ecoregions of the United States, and Level I-III Ecoregions of North America and 12-digit (6th level) hydrologic units.
