I want to know the answer to the following question:
What types of trees grow near rivers in western Oklahoma?
All the background I'm provided with is that "Forests cover 24 percent of Oklahoma and prairie grasslands composed of shortgrass, mixed-grass, and tallgrass prairie, harbor expansive ecosystems in the state's central and western portions, although cropland has largely replaced native grasses.". Is that enough to answer the question?
Answer: no
