Most national and regional protected area strategies include a protected area network as a fundamental component. IUCN WCPA´s definition and categorisation of protected area types allows policy makers and international organisations to quantify and understand this global network of protected areas; and the CBD´s Programme of Work on Protected Areas encourages the use of IUCN´s harmonised system for reporting protected areas. At the 2008 WCC IUCN WCPA launched a new edition of its Guidelines on IUCN Protected Area Management Categories; which introduced a new definition of a protected area, clarity on the use of the categories system and a range of governance types for protected areas. Since then IUCN WCPA has been working to help translate this global guidance into national application and highlight the benefits that the categories system can bring in the national context. This workshop will explore with participants implementation of the guidelines since 2008 and develop IUCN WCPA guidance for future application. The conservation campus will launch new supplementary guidance for the marine environment (MPAs) and will draw on recent application in South Korea, Northern and Western Europe, North and South America. Building on preparatory work carried out in 2012 leading up to the conservation campus, participants will be asked to review implementation experience and advice and contribute to the development of new IUCN WCPA guidance on the role of the categories in reporting protected areas nationally and using the categories to inform the development of protected areas which are effective, representative and equitable.
