What is the term for a wide area of parks of undeveloped land surrounding a community?

The term "greenbelt" refers to a designated area of undeveloped land surrounding a community, which aims to prevent urban sprawl and provide a buffer between urban and rural areas. A greenbelt can serve multiple purposes, such as preserving natural habitats, offering recreational opportunities, and maintaining the environmental quality of the area.

Greenbelts often include parks, agricultural land, and forested areas, enhancing the quality of life for residents by providing accessible green space. They help to enhance local biodiversity and create a more sustainable urban environment by promoting ecological stability and reducing the impact of urbanization.

While "greenway" also pertains to areas that promote outdoor activities, it typically refers to corridors that facilitate movement and connectivity for pedestrians, cyclists, and wildlife rather than specifically designating a broad area surrounding a community. "Nature reserves" are often more focused on conservation of specific ecosystems rather than serving as protective zones for community boundaries. "Parkland" generally denotes land set aside for public parks but does not encompass the broader application of undeveloped land specifically aimed at restraint against urban development, which is central to the concept of a greenbelt.
