ABSTRACT

In Costa Rica, researchers at the National Institute of Biodiversity (InBio) have developed the concept of ‘conservation overhead’ in which both academic and commercial research contribute directly to the information base and costs of maintaining protected areas. However,

• Category Ia: strict nature reserve/wilderness protection area managed mainly for science or wilderness protection – an area of land and/or sea possessing some outstanding or representative ecosystems, geological or physiological features and/or species, available primarily for scientific research and/or environmental monitoring;

• Category Ib: wilderness area – protected area managed mainly for wilderness protection; large area of unmodified or slightly modified land and/or sea, retaining its natural characteristics and influence, without permanent or significant habitation, which is protected and managed to preserve its natural condition;

• Category II: national park – protected area managed mainly for ecosystem protection and recreation; 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; area containing specific natural or natural/cultural feature(s) of outstanding or unique value because of their inherent rarity, representativeness or aesthetic qualities or cultural significance;

• Category IV: habitat/species management area – protected area managed mainly for conservation through management intervention; area of land and/or sea subject to active intervention for management purposes in order to ensure the maintenance of habitats to meet the requirements of specific species;

• Category V: protected landscape/seascape – protected area managed mainly for landscape/seascape conservation or recreation; area of land, with coast or 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 resources; area containing predominantly unmodified natural systems, managed to ensure long-term protection and maintenance of biological diversity, while also providing a sustainable flow of natural products and services to meet community needs.
