Have you ever stood on the state line, hopped across into your neighboring state, and hopped back? Not much to it after the third or fourth time, right? This is nature's first lesson: No human-made boundaries really apply to the landscape. Any changes that occur are more often gradual and related to complex ecological truths, rather than political, historical, or economic variables. Effective conservation often requires that we work across these jurisdictional boundaries, looking instead to more naturally defined areas.
Hence, the grouping of "natural geographies." They differ in scale because it is useful, on occasion, to refer to places based on specific scientific criteria -- sometimes large, sometimes small. Yet, Ecoregions, Ecological Divisions, Watersheds, and Corridors can all provide valuable frameworks for shaping on-the-ground land and water protection efforts.

The broadest of our natural geographies, Ecological Divisions grew out of the need to provide a larger ecological overlay to Ecoregions. They are bigger, often encompassing one or more Ecoregions, reflecting continent-scale observations of climate, physical description, and the biogeographic history of larger land areas.
