The protect_class=2 is added to a boundary=national_park or boundary=protected_area feature to describe lands that are set aside as national parks (IUCN Category II).
A ![[W]](/w/images/2/24/Wikipedia-16px.png "Wikipedia"){kind=small}
national park is a relatively large area of land declared by a government (just as boundary=administrative are declared/recognized by governments), to be set aside for human recreation and enjoyment, as well as the protection of the natural environment and/or cultural heritage of an area. This would normally also come with restrictions on human activity, particularly development, for the protection of wildlife and scenery. National parks are often named "X national park" (with translation). Note that national parks in the UK use protect_class=5 due to the coexistence of widespread farming and towns.
Category II: Large natural or near natural areas set aside to protect large-scale ecological processes, along with the complement of species and ecosystems characteristic of the area, which also provide a foundation for environmentally and culturally compatible spiritual, scientific, educational, recreational and visitor opportunities.

Examples
Examples of IUCN Category II National Parks:
Plitvice Lakes National Park, Croatia- Serengeti National Park, Tanzania
- Torres del Paine National Park, Chile
- Uluṟu-Kata Tjuṯa National Park, Australia
- Yosemite National Park, USA
- Zhangye National Geopark, China
Tagging Notes
National Park boundaries are tagged with either the older boundary=national_park or the newer boundary=protected_area.
Protected Area Categories
The protected area categores in OpenStreetMap were inspired by IUCN protected area categories, or IUCN protected area management categories, the categories used to classify protected areas in a system developed by the International Union for the Conservation of Nature (IUCN).[1][2]
The IUCN has developed the protected area management categories system to define, record, and classify the wide variety of specific aims and concerns when categorising protected areas and their objectives. In addition to publishing conservation category definitions, IUCN also maintains the Green List, a listing of a small number of conservation areas that are certified by the IUCN for their conservation practices.
The IUCN categorisation method is recognised on a global scale by national governments and international bodies such as the United Nations and the Convention on Biological Diversity.[3]
Unfortunately, the IUCN website appears to be copyright-protected, so the list of protected areas cannot be copied into OpenStreetMap.
Sources of IUCN Category Designations
Below is a non-exhaustive list of sources that mappers can consult when determining what which protect_class=* value to assign:
| Country | License | Source |
|---|---|---|
| United States | PD | U.S. Geological Survey, Science Analytics and Synthesis, Gap Analysis Project (GAP): Protected Areas Database of the United States 2.0 |
IUCN 75% Rule
Note that the IUCN definitions include the "75% rule", which says that an area may be categorised under one of the IUCN definitions if 75% of the area meets the category definition. This allows for a small amount of non-conservation land to exist within a larger tract, for example, to allow for visitor facilities.
protect_class=* values
| Criteria | protect_class=* |
|---|---|
| Human visitation is so strictly controlled that the area is suitable as a reference for scientific study. | protect_class=1a |
| Human visitation is permitted for those prepared for self-reliant travel such as on foot or by boat. The area has no established visitor infrastructure. The area is large enough that a journey to the interior represents a significant undertaking that requires special equipment. | protect_class=1b |
| The area encourages low-impact human visitation and recreation while conserving a special area of national importance. Often, the area is named a "National Park", or equivalent name in the local language; however, not all areas so named actually fit the criteria for category 2. | protect_class=2 |
| The area is designated in order to protect a unique or special natural feature. The natural feature is usually part of the name of the protected area. If there is an identifiable natural feature being protected, but is not a National Park, use this value. | protect_class=3 |
| The area is designated in order to protect a specific species. The protected area name usually indicates wildlife protection. | protect_class=4 |
| Areas which are preserved for conservation, but don't meet any of the criteria for classes 1 to 4 or class 6, should usually be tagged with this class, as a "protected landscape/seascape". | protect_class=5 |
| The area is designated in order to protect a natural resource, or some other human use of land including tourism, with a parallel goal of conservation. | protect_class=6 |
