Ecoregions/Natural Divisions of Arkansas

When ecologists first began considering that different parts of Arkansas have different characteristics, they called those areas "natural divisions." Today, that term is synonymous with "natural regions" and "ecoregions." We are proud that ANHC took the lead more than 30 years ago to produce materials to help teach about Arkansas. We continue to use and update these materials today, with programs, lessons plans, worksheets, and study and classroom guides.
