Partially protected areas (PPAs) are spatial zones within marine protected area (MPA) networks that allow some resource extraction – such as commercial or recreational fishing. Currently these areas are considered within MPA target figures for the IUCN 30x30 goals. Theoretically, PPAs help to provide biodiversity, social, and economic benefits to a particular region (triple bottom line management). Other Effective area-based Conservation Measures (OECMs) are spatial zones that provide biodiversity benefits through means other than MPAs. Some examples of marine OECMs are fisheries management tools such as spatial or temporal closures, gear or sector exclusions, and habitat restoration projects.
In this project we have assessed PPA implementation across Australia through a systematic literature review of peer-reviewed publications, and legislative documentation. The review outlines the types and forms of partial protection used in Australia, including OECMs, and the factors affecting the likelihood of attaining mutually beneficial outcomes for all marine users.
In this talk I will present the results of our literature review and outline our plans for a spatially-based quantitative decision-support tool for marine resource managers. The tool will allow informed decisions to be made when implementing conservation management strategies for marine areas within zones of high natural value in Australia.
