What are the grassland biomes known for?

Is grassland a forest?
The most extensive natural grasslands can be thought of as intermediates in an environmental gradient, with forests at one end and deserts at the other. Forests occupy the most favourable environments, where moisture is adequate for growth and survival of a tall, dense vegetation dominated by trees.
How are grasslands different from forests?
Grasslands are found where there is not enough regular rainfall to support the growth of a forest, but not so little that a desert forms. In fact, grasslands often lie between forests and deserts. Still, only a small percentage—less than 10 percent—of the world’s grassland is protected….

Why do prairies have no trees?
Originally Answered: Why do big trees not grow in grasslands? Because the grasslands are packed with grass, which makes a dense turf of intermeshing roots just below ground. These roots take up all the water. As a result, the soil is not rich enough to meet a tree’s needs.

Having said this, the Midwest is a huge area, stretching from the Pennsylvania-Ohio border all the way out to Colorado. There are areas with extensive forest in the Midwest, especially around the Great Lakes….
