Definition
Hills describe protected landscapes characterized by rounded summits, rolling slopes, low ridges, saddles, and repeating elevation changes. The term is used here as a physical-geography feature rather than a legal park designation.
This atlas category is descriptive rather than regulatory: it does not imply a protection class, management standard, or minimum size. Local examples may be known by terms such as rolling hills or hill country, but those names can carry narrower regional meanings. The shared category is useful because it identifies a comparable landscape pattern while leaving room for geological and ecological variation.
Clear boundaries are especially important where hills overlaps with related landforms in the same protected area.
