Abstract

ABSTRACT: Australia’s endemic flatback turtle Natator depressus is the focus of a long-term conservation program aimed at securing the persistence of healthy populations in the northwest of Australia into the future. Primary threats to flatback turtles include (1) sea level rise, (2) predation from introduced species, (3) temperature increases, (4) onshore and nearshore light, (5) marine debris, and (6) modification to beaches. Population declines resulting from these threats have been reported or are anticipated, and a range of intervention options are possible that may limit their negative impact. Following methods previously developed and applied to iconic marine species and habitats, we generated a range of intervention options, and asked experts to prioritise those actions using an intervention prioritisation tool (IPT) and the public to prioritise based on social acceptability assessment (SAS). The IPT allows different conservation interventions to be assessed based on their economic cost, implementation feasibility, social acceptability, and perceived effectiveness in maintaining or increasing future turtle populations while simultaneously accounting for expert confidence in their assessment. Results generated by the IPT and SAS can be explored further to resolve uncertainty, a process that can help managers and experts alike in their decision-making process associated with flatback conservation. While this paper is focused on interventions relating to flatback turtles, we propose that our IPT can be applied in different settings to enable consideration of interventions for a range of threatened species and habitats to guide research and conservation investment decisions by managers.

扁背海龟的未来--评估保护干预措施,减少对澳大利亚特有海龟的威胁
ABSTRACT: 澳大利亚特有的扁背海龟 Natator depressus 是一项长期保护计划的重点,该计划旨在确保澳大利亚西北部的健康种群在未来能够持续存在。平背海龟面临的主要威胁包括:(1)海平面上升;(2)外来物种的捕食;(3)温度升高;(4)陆地和近岸光照;(5)海洋废弃物;(6)海滩改造。已有报告或预计这些威胁会导致种群数量下降,有可能采取一系列干预措施来限制其负面影响。按照之前开发并应用于标志性海洋物种和栖息地的方法,我们生成了一系列干预方案,并请专家使用干预优先级排序工具(IPT)对这些行动进行优先级排序,请公众根据社会可接受性评估(SAS)进行优先级排序。IPT 可以根据不同保护干预措施的经济成本、实施可行性、社会可接受性以及在维持或增加未来海龟数量方面的预期效果对其进行评估,同时考虑专家对其评估的信心。可以对 IPT 和 SAS 得出的结果进行进一步探讨,以解决不确定性问题,这一过程可以帮助管理者和专家做出与保护扁背海龟相关的决策。虽然本文的重点是与扁背海龟有关的干预措施,但我们建议将 IPT 应用于不同的环境,以便考虑对一系列濒危物种和栖息地采取干预措施,从而指导管理者做出研究和保护投资决策。

期刊介绍: ESR is international and interdisciplinary. It covers all endangered forms of life on Earth, the threats faced by species and their habitats and the necessary steps that must be undertaken to ensure their conservation. ESR publishes high quality contributions reporting research on all species (and habitats) of conservation concern, whether they be classified as Near Threatened or Threatened (Endangered or Vulnerable) by the International Union for the Conservation of Nature and Natural Resources (IUCN) or highlighted as part of national or regional conservation strategies. Submissions on all aspects of conservation science are welcome.
