Online_Linkage: http:\\sagemap.wr.usgs.gov Description: Abstract: This model was constructed to model the risk of invasion by exotic plant species. Roads may directly influence exotic plant dispersal via disturbance during road construction or via alterations in soil regimes. For example, in Californian serpentine soil ecosystems exotic plant species can be found up to 1km from the nearest road , and Russian thistle (Salsola kali), an exotic forb growing along roads, is wind-dispersed over distances greater than 4km. Roads may also indirectly facilitate the dispersal of exotic grasses, such as crested wheatgrass (Agropyron cristatum), via human seeding along road verges or in burned areas near roads as a management strategy to curb the establishment of less desirable exotic grass species. The inputs for this model are road type , distance from road , forest - non-forest vegetation , and proximity to rural-urban and agricultural areas. Three road-based models were built based on the classification of road type and four distance risk classes. Interstates, federal and state highways received a higher risk than secondary roads because secondary roads with shallow road verges are poorer exotic plant dispersers compared to the other two road types . Because exotic plant invasion in forest areas is restricted to roads and riparian corridors , we included only the highest risk class within forested areas. Last, because urbanized and agricultural areas act as exotic plant sources, we classified the populated areas and agricultural lands as high risk. The three road models and the populated areas and agricultural land models were merged by selecting the maximum value at each pixel location from the five input grids using the MAX command in ARC/INFO. Purpose: Map the risk of invasion by exotic plant species.

A ratio of points containing an exotic species to total points in the risk class was calculated for each risk class. Results are as follows: 0 = 0.0780 (n = 14876); 1 = 0.1607 (n = 16818); 2 = 0.2226 (n = 14869); 3 = 0.2197 (n = 14441). Logical_Consistency_Report: Dependent on the logical consistency of the data from which this coverage was created. No additional checks for consistency or accuracy was completed on this final product. Completeness_Report: Based on the completeness of the data from which this coverage was created. Review metadata for individual source coverages to assess completeness of each.
