IUCN-WCPA’s Best Practice Protected Area Guidelines are the world’s authoritative resource for protected area managers. Involving collaboration among specialist practitioners dedicated to supporting better implementation of ideas in the field, the Guidelines distil learning and advice drawn from across IUCN. Applied in the field, they build institutional and individual capacity to manage protected area systems effectively, equitably and sustainably, and to cope with the myriad of challenges faced in practice. The Guidelines also assist national governments, protected area agencies, non-governmental organisations, communities and private sector partners in meeting their commitments and goals, and especially the Convention on Biological Diversity’s Programme of Work on Protected Areas. Although focused on aiding managers, these Guidelines are for anyone involved in supporting LSMPAs or the communities that hold an interest in them. It is hoped these Guidelines will also assist new LSMPAs from the earliest design phase, and enhance the management of existing LSMPAs from planning and implementation through ongoing evaluation.
