Important Considerations:
* Ecoregions are not defined by a single landform. They are more complex areas with varying landscapes, climates, and ecosystems.
* There can be overlaps between regions. For example, the Trans-Pecos region borders the Edwards Plateau and shares some landforms.
* Many landforms are found across multiple ecoregions. For instance, canyons are present in the High Plains, Edwards Plateau, and Trans-Pecos.
