Nature reserve
A legally or administratively protected area managed to conserve wildlife, habitats, geological features, or other natural values.
Protected area: A geographically defined area designated and managed to achieve long-term conservation of nature. Nature reserves are one form of protected area, alongside parks and other designations.
Marine protected area: A defined marine area managed to conserve ecosystems, species, or cultural values. Marine reserves apply protected-area principles to ocean and coastal environments.
National park: A large protected landscape designated for nature conservation, recreation, or both. National parks often encompass broader landscapes and public access than strict reserves.
Habitat fragmentation: The division of continuous habitat into smaller, more isolated patches. Fragmentation can isolate reserves and reduce the movement and viability of wildlife populations.
Yellowstone National Park: A United States national park established in 1872, widely recognized as the first national park. Its creation helped establish the model of state-protected landscapes, though reserves have varied histories.
IUCN protected area categories: A framework classifying protected areas by their primary management objectives. Its categories distinguish strict reserves from areas permitting sustainable use.
Biosphere reserve: A UNESCO designation for places linking biodiversity conservation with sustainable development and research. Its zoned landscapes combine core conservation areas with surrounding human use.
Wilderness area: A protected area managed to preserve large, predominantly unmodified natural conditions. Wilderness designations emphasize minimal human influence, unlike reserves with varied management aims.
Edge effect: Ecological changes near the boundary between two habitat types. A reserve’s edges may experience altered conditions and greater exposure to outside disturbance.
John Muir: A Scottish-American naturalist and writer who advocated protecting wild landscapes in the United States. His conservation advocacy influenced public support for protected natural areas.
