What are 3 major biomes in Oklahoma?

Three major biomes in Oklahoma are the grassland, forest, and wetland biomes. The grassland biome, particularly the tallgrass prairie, covers much of the state and is characterized by vast open spaces with grasses and few trees. The forest biome, primarily found in the eastern part of the state, features hardwood trees like oak and hickory. Wetlands, including marshes and swamps, are located in various areas and support diverse aquatic and terrestrial ecosystems.
