Process Date |
Conservation sites were digitized manually in ArcView based on several sources of information. Sites were first delineated from the convergence of overlapping polygons of the expert-nominated areas (see Xprtmerg.shp). Boundaries were refined by considering the (1) records for Conservation Targets from the Natural Heritage Program databases; (2) target occurrence data provided by experts (May 1998 Experts Workshop) and from primary and grey literature not currently in a digital database (e.g., wilderness study area reports); (3) spatial data sets for the Ecoregion's topography, hydrography, land use/land cover, GAP vegetation (and equivalent data for Mexico), land management status, and Thematic Mapper satellite imagery; and (4) indices of biophysical variation from biophysical modeling exercise. |
