Optimum species selection of several grass types are dependent on both soil and climate factors. High-resolution gridded climate and soils data have been placed into an intelligent GIS system and delivered through Internet technology to allow researchers to investigate the interactions of these factors in determining suitable locations for growing grasses. A look at this Internet application shows how Internet mapping systems can provide scientists or managers without GIS skills or technology, a means to make decisions or provide feedback into modeling efforts seeking to find optimum site locations for growing certain type of grasses. This type of modeling could also be extended to any type of plant adaptation that is dependent on both soil and climate conditions.
