• Prior to conducting the floristic surveys, records of the Colorado Natural Areas Inventory <br />{CNAI) database (Colorado Natural Areas Program) were checked to ascertain the potential <br />occurrence of rare, threatened, or exemplary plants and plant communities in the New Horizon <br />2 study area. Care was taken during the floristic surveys to thoroughly search each vegetation <br />type for plant species that are listed or proposed for listing as threatened, endangered, or <br />exemplary in Colorado. <br />The comprehensive plant species list was organized for reporting purposes by morphological <br />class; i.e., annual or perennial graminoids, annual or perennial (orbs, shrubs and subshrubs, <br />trees, succulents, vines and aquatics. Each taxon was further identified by scientific binomial, <br />common name, origin, and habitat occurrence. Taxonomy and nomenclature followed Weber <br />(1987), Hermann (1975), and Hermann (1970). Beetle (1970), Nickerson et al. (1976), and <br />SCS (1979) were consulted in an effort to apply the most widely accepted common names. <br />Floristics - 1999. The original 1987 floristic survey was updated and augmented as species <br />were encountered during sampling and during extensive field reconnaissance of the area. <br />Similarly, care was taken during the floristic surveys to thoroughly search each vegetation type <br />• for plant species that are listed or proposed for listing as threatened, endangered, or exemplary <br />in Colorado. Nomencalature for species added to the floristics list is that used by the NRCS <br />PLANTS database of plants in the US. <br />Sample Point Selection - 1987. Individual sample point locations, and line or belt transect <br />origins were selected using pairs of randomly-generated numbers. Pairs of random numbers, <br />treated as Cartesian coordinates, were plotted on x and y axes drawn on the base map until a <br />sufficient number of points were located in each vegetation type to achieve the desired <br />maximum samples sizes required. Randomly-generated numbers were also used to define the <br />compass direction at which the line or belt transects would be oriented from the origin. The <br />random numbers generator in aHewlett-Packard 11-C hand-held calculator was used to <br />generate the coordinate pairs and compass bearings. <br />The sample point locations, and line or belt transect origins were located on the ground by <br />pacing the required distances and directions from recognizable landmarks on the base map <br />such as fencelines, corner posts, road intersections, and building corners.
