IUCN has defined a series of protected area management categories based on management objective.Definitions of these categories, and examples of each, are provided in Guidelines for Protected Area Management Categories (IUCN, 1994).The six categories are:
CATEGORY Ib : [Wilderness Area]: protected area managed mainly for wilderness protection Definition:Large area of unmodified or slightly modified land, and/or sea, retaining its natural character and influence, without permanent or significant habitation, which is protected and managed so as to preserve its natural condition.
CATEGORY II : [National Park]: protected area managed mainly for ecosystem protection and recreation Definition:Natural area of land and/or sea, designated to (a) protect the ecological integrity of one or more ecosystems for present and future generations, (b) exclude exploitation or occupation inimical to the purposes of designation of the area and (c) provide a foundation for spiritual, scientific, educational, recreational and visitor opportunities, all of which must be environmentally and culturally compatible.
CATEGORY III : [Natural Monument]: protected area managed mainly for conservation of specific natural features Definition: Area containing one, or more, specific natural or natural/cultural feature which is of outstanding or unique value because of its inherent rarity, representative or aesthetic qualities or cultural significance.
CATEGORY IV : [Habitat/Species Management Area]: protected area managed mainly for conservation through management intervention Definition:Area of land and/or sea subject to active intervention for management purposes so as to ensure the maintenance of habitats and/or to meet the requirements of specific species.
CATEGORY V : [Protected Landscape/Seascape]: protected area managed mainly for landscape/seascape conservation and recreation Definition: Area of land, with coast and sea as appropriate, where the interaction of people and nature over time has produced an area of distinct character with significant aesthetic, ecological and/or cultural value, and often with high biological diversity. Safeguarding the integrity of this traditional interaction is vital to the protection, maintenance and evolution of such an area.
CATEGORY VI : [Managed Resource Protected Area]: protected area managed mainly for the sustainable use of natural ecosystems Definition: Area containing predominantly unmodified natural systems, managed to ensure long term protection and maintenance of biological diversity, while providing at the same time a sustainable flow of natural products and services to meet community needs.
