1. Modeling Terrestrial Ecosystem Distribution, Mapping Threats and Updating Protected Area Information Leonardo Sotomayor South America Conservation Region

2. Terrestrial Ecosystems A layer of contiguous vegetation-based ecological systems as conservation targets Contracted NatureServe to develop the classification (Josse et al 2003), but had no map Project lead by Roger Sayre (now at USGS) Data now being used for various applications including preliminary biodiversity assessments and effective conservation measures Data is undergoing final updates and revisions prior to distribution

3. Ecosystem Classification Elevation Unique Gridcodes Landform Geology Landcover Bioclimate Terrestrial Ecosystems ModelingNS Classification

4. Elevation 450 Meter Digital Elevation Model Data (DEM) produced by WWF from 90 meter SRTM DEM data. Classification is based primarily on floristics: –0 - 500m: corresponds to lowlands –500 - 1000m: transitional mixed flora of the piedmont, in the case of massive ridges like the Andes; or is already montane, with a different set of species, in the case of low ridges –1000 - 3300m: two life zones in the mountains, mostly forest covered –Over 3300m: treelines for the Andes

6. General Landform Landforms were developed using a neighborhood analysis using DEM General Landform ClassDescription Plains0 – 25 meters relative relief Rolling Plains25- 50 meters relative relief Hills25 – 300 meters relative relief Mountainsover 300 meters relative relief PlateausDetailed description in report River Valleys / Mountain PlateausDetailed description in report FloodplainsDetailed description in report Coastal PlainsPlains adjacent to the coast on alluvial type geology

8. General Geology Detailed geology data was purchased from Geologic Data Systems Inc. (GDS). Compiled geological information from over 50 published maps to create a digital geology map of South America. Data for Brazil was compiled at 1:1,000,000 scale with the remainder of South America at 1:500,000 scale.

17. Gridcodes Each unique gridcode represents a combination of the 5 input data layers numeric codes For example, the unique gridcode for one polygon might be 1742020, which represents: 1000000 0 – 500 meters 700000Floodplains 40000 Alluvium 2000 Tropical Pluvial-seasonal 20Tree Cover, Broadleaf Deciduous
