The Sea Level Rise Affecting Marshes Model (SLAMM) simulates the dominant processes involved in wetland conversions and shoreline modifications during long -term sea level rise. http: / /www.fws.gov /slamm/ or http :// warrenl2innacle.com /12rof /SLAMM /index.html Land Use and Land Cover Data The USGS Gap Analysis Program (GAP) recently released a national land cover map (based on 2001 satel- lite data) and online map viewer. These maps utilize the NatureServe Ecological Systems Classification, which provides a consistent, detailed classification of vegetative types across the U.S. The National GAP land cover map contains 551 cover classes (82 of which are occur in North Carolina). httl2://www.gal2.uidaho.edu/land- cover.html Regional and state subsets of the national data are available thro e goal of monitoring these habitats by updating the land cover maps every five years. Data are available for 2006, 2001, and 1996. http: / /www.csc.noaa.gov/ crs /lca /locateftp.html The National Land Cover Database (NLCD) 2001 is based on satellite imagery compiled across all 50 states and Puerto Rico as a cooperative mapping effort of the MRLC Consortium. This land cover database contains standardized land cover components classified using the Anderson scale. A 1992 data set is also available, although somewhat different methodology was used to classify the earlier data set. Data are available by zone or using the seamless map server. The NLCD 1992/2001 Retrofit Land Cover Change Product provides land cover change information at the Anderson Level I classification scale across the two time periods. In addition, two derived data sets are available, NLCD 2001 Urban Imperviousness, and NLCD 2001 Percent Canopy. http: / /www.mrlc.gov/ The SILVIS Lab at the University of Wisconsin - Madison produces maps showing the Wildland -Urban Interface. National and state maps and data are available for download. Housing Density models are also available by decade from 1940 — 2030. http: // silvis.forest.wisc.edu /mal2s.asl2 The Biodiversity and Spatial Information Center (BaSIC) is currently using SLEUTH -R ( Jantz et al. 2010) to model urban growth as part of the "Designing Sustainable Landscapes" project. The DSL Project uses vegetation (VDDT /TELSA) and the urban dynamics modeling to examine the potential impacts of landscape -level changes on the future capability of habitats to support wildlife populations (Adam Terand, personal communication, www.basic.ncsu.edu /dsl). These modeling approaches are currently being applied throughout the Southeastern U.S. as a part of the USGS's Southeastern Regional Assessment Project (http: // serail. er. usgs. gov /) . Jantz, C.
