Page "Protected area" Paragraph 5

Protected areas are designated with the objective of conserving biodiversity and providing an indicator for that conservation's progress, but the extent to which they defend resources and ecosystem dynamics from degradation are slightly more complex.

Protected areas will usually encompass several other zones that have been deemed important for particular conservation uses, such as Important Bird Areas ( IBA ) and Endemic Bird Areas ( EBA ), Centres of Plant Diversity ( CBD ), Indigenous and Community Conserved Areas ( ICCA ), Alliance for Zero Extinction Sites ( AZE ) and Key Biodiversity Areas ( KBA ) among others.

Likewise, a protected area or an entire network of protected areas may lie within a larger geographic zone that is recognised as a terrestrial or marine ecoregions ( see, Global 200 ), or a crisis ecoregions for example.
