Level I is the coarsest level, dividing North America into 15 broad ecological regions. The 50 level II North American ecological regions provide a more detailed description of the large ecological areas nested within the level I regions and are useful for national and sub-continental overviews of ecological patterns. The 182 level III ecological regions, smaller ecological areas nested within level II regions, enhance regional environmental monitoring, assessment and reporting, as well as decision-making.
