Denver's designated natural areas keep prairie inside the city

Picture Denver and you usually picture streets, shade trees, mowed lawns, and brick neighborhoods. Underneath that, the park system holds a quieter layer of native landscape, kept on purpose and managed by a lighter hand.

Five of these places carry the designation of natural area: Parkfield, Inspiration Point, Heron Pond, Camp Rollandet, and Paul A. Hentzell. They are managed as special portions of open, undeveloped land rather than as ordinary parks. Within their boundaries the work is aimed at protecting native vegetation, wildlife habitat, intact plant communities, geological formations, water corridors, and wetlands.

What sets them apart from a turf park is exactly what they are not doing. A natural area can look unkempt because constant mowing is not the goal. Native grasses and streamside plants are left to create habitat, hold the soil in place, and keep a living trace of the prairie that Denver was built on, the same High Plains ground that runs out east toward the horizon.

Denver also treats these spots as outdoor classrooms and places of local memory, a way to read the old plains ecology without leaving the city. They are a reminder that Denver’s outdoor life is not only a drive west to the foothills. Some of it has been here all along, in the wetland edges and unmowed grass between the neighborhoods.
