In a nutshell, grassland is a perennial, open, evergreen shrub or tree that grows on open, marshy, or shallow surfaces.
It may be a dense, multi-branched woody plant, a dense evergreen, or a single-branch shrub.
In the U.S., grasslands include grasslands in the western United States and the eastern U.K., and some areas in the Northern Rockies and Canadian Rockies.
Grasslands are often considered a form of natural vegetation because they contain little or no trees.
However, grasslands are not the only types of plants to be classified as grassland.
The term “grassland” is sometimes used to describe any grassland ecosystem that contains many or more plants.
For example, the term “urban lawn” refers to a wide swath of grasslands, which includes most areas in urban areas.
Other terms for grasslands also exist, such as grasslands that have dense populations of trees and shrubs and a dense population of trees or shrubs.
The National Park Service defines a grassland as a “landscape of trees, shrubs, or other grasses.”
The definition does not include landscapes of other plant species that grow on open or marshy surfaces, but the grasslands do not need to be as dense as those.
The Park Service does not classify a grasslands as a landscape of trees because the Park Service has concluded that a large number of these species, which range from native to exotic, have the capacity to form dense woody structures.
Some of the most common types of grassland ecosystems include the following: shrubs: shrub trees and grasses, including native species such as oak, hemlock, and holly.
