Background Protected areas (PAs) are globally considered as one of the primary methods to preserve biodiversity, ecosystem services and other global environmental benefits (GEBs) such as maintenance of carbon stocks. The amount of land placed under some kind of protection has been growing steadily at the global scale, a fact highlighted by the recent Global Biodiversity Outlook 2010 as one of the very few positive achievements over the past years to protect the Earth‟s biological and genetic resources, and help to maintain ecosystem processes. PAs are diverse in their governance and objectives and defy simple definition. Types of PAs have been categorised by the World Commission on Protected Areas (WCPA) of the International Union for the Conservation of Nature (IUCN) and used to classify entries in the World Database of Protected Area
