Ecoregionization is a process of delineating and classifying ecologically distinctive areas of ecological land. Each area can be viewed as a discrete system that has resulted from the mesh and interplay of the geologic, landform, soil, vegetative, climatic, wildlife, water, and human factors where ecological functions and processes are continuing. The dominance of any one or more of these factors varies with the given ecological land unit. This holistic approach to land classification can be applied incrementally on a scale-related basis from site-specific ecosystems to very broad ecosystems (1). Ecological processes, evolutionary mechanisms, and geological forces are continually reshaping landscapes across various scales of time and space and result in distinctive but dynamic ecoregions. All of the world's food and most medicines and raw materials are derived from these processes and associated biodiversity. Thus ecoregions gain their identity through spatial differences in a combination of landscape characteristics. Several factors such as topography, hydrology, and nutrients are important to identify these characteristics that may vary from one place to another in an ecoregion.
