Putting conservation priority‐setting for marine turtles in context

Putting conservation priority‐setting for marine turtles in context Globally distributed, highly migratory marine megafauna present serious challenges to designing effective conservation strategies that target specific habitats and threats to population persistence. Marine turtles exhibit several characteristics that make multiple population levels, life‐history traits, and stages potentially appropriate targets for conservation ( Wallace , 2010 ), including distinct feeding and breeding areas for adults, geographically separated ontogenetic habitats, and complex population structures ( Bowen & Karl, 2007 ). Different threats that operate on various spatial scales can differentially affect the same marine turtle population, warranting distinct conservation actions. Although the International Union for the Conservation of Nature (IUCN) Red List ™ provides conservation status assessments for marine turtle species at a global level, these listings belie regional variations in population sizes and trends ( Wallace , 2010 ).

Abstract

Globally distributed, highly migratory marine megafauna present serious challenges to designing effective conservation strategies that target specific habitats and threats to population persistence. Marine turtles exhibit several characteristics that make multiple population levels, life‐history traits, and stages potentially appropriate targets for conservation ( Wallace , 2010 ), including distinct feeding and breeding areas for adults, geographically separated ontogenetic habitats, and complex population structures ( Bowen & Karl, 2007 ). Different threats that operate on various spatial scales can differentially affect the same marine turtle population, warranting distinct conservation actions. Although the International Union for the Conservation of Nature (IUCN) Red List ™ provides conservation status assessments for marine turtle species at a global level, these listings belie regional variations in population sizes and trends ( Wallace , 2010 ). This discrepancy has led the IUCN/SSC Marine Turtle Specialist Group (MTSG) to advocate for regional assessments at several scales below the species level that have been defined as biologically discrete population units ( Seminoff & Shanker, 2008 ). In a new paper, Bass, Anderson & De Silva (2011) applied the Key Biodiversity Area (KBA) approach to marine turtle nesting sites in Melanesia. As KBAs originally were developed for terrestrial
