PROPOSED APPROACH FOR THE IDENTIFICATION OF IMPORTANT MARINE AREAS FOR CONSERVATION: USING ‘MARXAN’ SOFTWARE TO SUPPORT SYSTEMATIC CONSERVATION PLANNING
Abstract: We provide a worked example of how a systematic conservation planning methodology ... (Margules & Pressey, 2000) might be used to identify important areas for conservation of biodiversity in ... the pelagic environment, using Subarea 48.2 (South Orkney Islands) as a pilot study area. The aim of ... the worked example is not to identify areas for protection or management at this stage, but rather to ...
