Use of surrogate species to cost‐effectively prioritize conservation actions

Conservation efforts often focus on umbrella species whose distributions overlap with many other flora and fauna. However, because biodiversity is affected by different threats that are spatially variable, focusing only on the geographic range overlap of species may not be sufficient in allocating t...

Description
Summary:Conservation efforts often focus on umbrella species whose distributions overlap with many other flora and fauna. However, because biodiversity is affected by different threats that are spatially variable, focusing only on the geographic range overlap of species may not be sufficient in allocating the necessary actions needed to efficiently abate threats. We developed a problem‐based method for prioritizing conservation actions for umbrella species that maximizes the total number of flora and fauna benefiting from management while considering threats, actions, and costs. We tested our new method by assessing the performance of the Australian federal government's umbrella prioritization list, which identifies 73 umbrella species as priorities for conservation attention. Our results show that the federal government priority list benefits only 6% of all Australia's threatened terrestrial species. This could be increased to benefit nearly half (or 46%) of all threatened terrestrial species for the same budget of AU$550 million/year if more suitable umbrella species were chosen. This results in a 7‐fold increase in management efficiency. We believe nations around the world can markedly improve the selection of prioritized umbrella species for conservation action with this transparent, quantitative, and objective prioritization approach. Uso de Especies Sustitutas para Priorizar las Acciones de Conservación de Manera Rentable Resumen Los esfuerzos de conservación comúnmente se enfocan en las especies paraguas cuyas distribuciones se traslapan con la de muchos otros componentes de la flora y fauna. Sin embargo, como la biodiversidad se ve afectada por diferentes amenazas que presentan una variabilidad espacial, enfocarse solamente en el traslape de la extensión geográfica de las especies puede no ser suficiente para la asignación de las acciones necesarias para abatir eficientemente a las amenazas. Desarrollamos un método basado en problemas para la priorización de las acciones de conservación para las especies paraguas, el cual maximiza el total de flora y fauna beneficiado con el manejo a la vez que considera amenazas, acciones y costos. Probamos nuestro método al valorar el desempeño de la lista de priorización de especies paraguas del gobierno federal de Australia, la cual identifica a 73 especies paraguas como prioritarias para la atención de la conservación. Nuestros resultados muestran que la lista de prioridades del gobierno federal beneficia sólo al 6% d
