IUCN category ib

Wilderness Area

Wild natural area151 parks
IUCN Category Ib is used for large areas where natural character, ecological continuity, and the experience of wildness are central to protection. A Wilderness Area is not defined merely by scenic value or low population density. It is protected because it remains largely free from industrial development, intensive infrastructure, and permanent or significant human settlement, and because preserving that condition is itself a major conservation goal. Category Ib sits close to Category Ia in its strong protection emphasis, but it is distinguished by scale, landscape continuity, and the explicit idea of wilderness as a value to be maintained.

Example parks

Congaree National ParkIsle Royale National ParkInyo National ForestGlacier Peak WildernessMount Hood Wilderness

Management focus

A usually large, unmodified or only slightly modified area protected to preserve its natural character, ecological integrity, and sense of wilderness without permanent or significant human habitation.

IUCN category ii

National Park

Ecosystem protection50 parks
IUCN Category II is one of the most widely recognized protected-area categories in the world because it brings together strong ecosystem protection and public-facing values. A National Park is meant to conserve large-scale ecological processes and representative species and ecosystems, but it is also expected to support compatible spiritual, scientific, educational, recreational, and visitor opportunities. This makes Category II especially important for countries that want protected areas to function both as core conservation landscapes and as places where people can meaningfully experience nature without undermining long-term ecological goals.

Example parks

Grand Canyon National ParkYellowstone National ParkYosemite National ParkGreat Smoky Mountains National ParkZion National Park

Management focus

A large natural or near-natural protected area managed to safeguard ecological processes, characteristic species, and ecosystems while also supporting education, recreation, and compatible visitor use.

IUCN category v

Protected Landscape/Seascape

People and nature36 parks
IUCN Category V recognizes that some of the world's most valuable conservation landscapes are not places without people, but places shaped by a long and continuing interaction between people and nature. In these areas, biodiversity, cultural identity, local livelihoods, scenic quality, and historical land-use patterns are often deeply intertwined. The category is used where safeguarding the integrity of that interaction is itself essential to conservation. Category V is therefore especially relevant to lived-in landscapes and seascapes whose value depends on continuity, stewardship, and the maintenance of characteristic ecological and cultural patterns over time.

Example parks

Redwood National and State ParksAcadia National ParkDenali National Park and PreserveGlacier Bay National Park and PreserveGreat Sand Dunes National Park and Preserve

Management focus

A protected area where the long-term interaction of people and nature has created a distinct landscape or seascape with significant ecological, cultural, and scenic value.

IUCN category iv

Habitat/Species Management Area

Targeted habitat management6 parks
IUCN Category IV is built around focused ecological management. Rather than emphasizing wilderness, a singular monument, or broad public recreation, this category is used where the central task is to maintain, conserve, restore, or manage particular species, habitats, or ecological conditions. Many Category IV areas require active intervention, sometimes on an ongoing basis, because their conservation values depend on management actions such as water-level control, grazing regimes, fire management, invasive-species removal, nest-site protection, or habitat restoration. The category is especially important for places where biodiversity goals are precise, operational, and management-intensive.

Example parks

Olympic Coast National Marine SanctuaryHawaiian Islands Humpback Whale National Marine SanctuaryGuana Tolomato Matanzas National Estuarine Research ReserveGrand Bay National Estuarine Research ReserveDelaware National Estuarine Research Reserve

Management focus

A protected area managed mainly to protect particular species or habitats, often through targeted, regular, or adaptive conservation interventions.

IUCN category vi

Protected Area with Sustainable Use of Natural Resources

Conservation with sustainable use5 parks
IUCN Category VI is used for protected areas where conservation remains primary, but where the sustainable use of natural resources is recognized as a legitimate and integrated part of management. These are usually large areas that remain mainly in a natural condition and that conserve ecosystems, associated cultural values, and traditional resource-management systems. The category is especially important in places where conservation is best achieved not by excluding all use, but by supporting forms of use that are low-level, non-industrial, ecologically compatible, and embedded in long-term stewardship.

Example parks

Shoshone National ForestOuachita National ForestHiawatha National ForestOttawa National ForestHuron–Manistee National Forests

Management focus

A generally large protected area that conserves ecosystems and cultural values while allowing compatible, low-level, non-industrial use of natural resources as part of its management approach.

IUCN category iii

Natural Monument or Feature

Specific natural feature2 parks
IUCN Category III is designed for places where protection centers on a particular natural feature rather than on a very large ecosystem or wilderness landscape. The protected feature may be geological, geomorphological, marine, biological, or a striking living element of nature such as an ancient grove or monumental tree stand. The category is especially useful when a specific natural landmark carries exceptional ecological, scientific, cultural, educational, or scenic importance and needs focused legal and management protection.

Example parks

Sleeping Bear Dunes National LakeshorePictured Rocks National Lakeshore

Management focus

A protected area established to conserve a specific natural feature such as a landform, geological structure, cave, seamount, waterfall, grove, or other distinct natural monument.

IUCN category ia

Strict Nature Reserve

Highest protection2 parks
IUCN Category Ia represents the most tightly protected end of the protected-area spectrum. A Strict Nature Reserve is primarily established to conserve biodiversity, geodiversity, or especially fragile ecological conditions by keeping direct human pressure extremely low. These areas are usually not designed around recreation, broad tourism, or everyday public access. Instead, they are places where ecological integrity comes first, and where entry, use, and management interventions are normally limited to what is necessary for conservation, research, monitoring, and tightly controlled stewardship.

Example parks

Rose Atoll National Wildlife RefugeCeiba State Forest

Management focus

A highly protected area managed mainly for science, monitoring, and the safeguarding of biodiversity, geological features, or ecological processes with minimal human disturbance.
