| Abstract: | Landscape maps of pest risk in the northeastern USA were produced for a hypothetical case study of an exotic plant disease (soybean rust) during the 1990 season. Published relations between the disease and a recently available high-resolution weather database were used to generate the maps. The landscape maps depicted patterns of risk using color classes overlaid with county boundaries at a spatial resolution of 1 km. The potential geographical impact of the exotic disease was estimated by interpreting a series of maps during a growing season. |
