Definition
Plateaus describe protected landscapes characterized by extensive high surfaces, escarpments, mesas, dissected edges, and interior basins. The term is used here as a physical-geography feature rather than a legal park designation.
The boundary of the category is deliberately broad enough to compare parks globally, but it should not erase local terminology or scientific distinctions. Features may overlap with mountains, canyon, cliffs, steppe, and a single park can legitimately contain several categories at once. Classification depends on the dominant physical expression and ecological influence, not simply on whether the feature appears somewhere inside a boundary.
Clear boundaries are especially important where plateaus overlaps with related landforms in the same protected area.
