Trout thrive in the high mountains, whereas other species are predominant in the Great Plains. Human influences may have altered biota from a natural state. Communities of biota are dynamic and respond to many complex factors and are subject to rapid change; for example, the vegetation associated with the Prairie Pothole region is temporarily very unstable (Lew Cowardin, written communication, 1993). In addition, various communities of biota may overlap but not coincide. Considering all the above, we can see that ecosystem maps based on the biogeographic distribution of aquatic or terrestrial species alone do not define an ecosystem.

Fire Regimes In the past, forest fires occurred at different magnitudes and frequencies in different climatic-vegetation types. In the boreal forest, for example, infrequent large-magnitude fires carried the flames in the canopy of the vegetation (crown fires), killing most of the forest. Other environments, such as lower-elevation ponderosa pine (Pinus ponderosa) forest in the western United States, had a regime of frequent, small-magnitude, surface fires. 6.
