overlaps composed primarily of planetary surface natural environment area protected according to IUCN guidelines IUCN protected area with sustainable use of natural resources protected area with sustainable use of natural resources Note that this ENVO class is not authoritative: see the associated IUCN references for a complete definition of all Protected Areas. Note, that the IUCN recommends that a proportion of the area is retained in a natural condition (e.g. a no-take management zone). As this is a recommendation rather than a rule, this ENVO class does not include IUCN categories with strict conservation regimes as necessary parts. An emphasis is placed on the integration of cultural approaches, belief systems and world-views possessed by human populations in and around the protected area into the conservation approaches used. Further, these areas host activities which facilitate scientific research, environmental monitoring, recreation, and "appropriate" small-scale tourism. IUCN-PACS:VI An IUCN protected area within which 1) natural ecosystems and their resources are either conserved or used through non-industrial human activities, 2) usage activites contribute to conservation goals, ensuring inter-generational security for local communities' livelihoods, and 3) the majority of benefits derived from the use of ecosystems are received by communities living near or in the area.
