Establishing clear, rationales for conservation actions is critical to optimizing the chances of rescuing threatened species worldwide. We propose a simple habitat suitability index, a trade-off between occupancy probability and extinction risk, to guide conservation actions for the blond capuchin monkey (Sapajus flavius), whose distribution spans the contrasting but adjacent Atlantic Forest and Caatinga phytogeographic domains of northeastern Brazil. Our objective was to create a map to spatially coordinated management options considering both domains under two divergent but plausible scenarios assuming contrasting conservation outcomes: (1) active conservation efforts, in which government agencies/communities agree to invest and participate in conservation actions; and (2) no intervention and no additional effort. Based on the habitat suitability index, sites were classified into three types: A (protected and suitable, n = 3); B (suitable but under high extinction risk, n = 9); and C (unsuitable and highly defaunated, n = 75). Our results show that under Scenario 1 it would be possible to fund an active taskforce to improve forest quality in habitat remnant types B and C while supporting monitoring and protection of type-A sites. However, little can be done under Scenario 2 without successful educational programs to raise awareness and change the perception of local stakeholders. This study introduces a spatial index to prioritise conservation actions at key sites, providing a practical approach to effective resource management in a changing environment. Our protocol may be useful in guiding conservation action in the face of resource constraints and rapid environmental and climatic change in increasingly threatened biodiversity hotspots.
为保护行动确立清晰合理的依据对于优化拯救全球濒危物种的几率至关重要。我们提出了一个简单的栖息地适宜性指数，即占用概率与灭绝风险之间的权衡，以指导对金毛卷尾猴（Sapajus flavius）的保护行动，该物种的分布跨越了巴西东北部形成鲜明对比但相邻的大西洋森林和卡廷加植物地理区域。我们的目标是创建一幅地图，以便在两种不同但合理的假设情景下，考虑到这两个区域，对空间协调管理方案进行规划，这两种情景假设了截然不同的保护结果：（1）积极的保护努力，即政府机构/社区同意投资并参与保护行动；（2）不干预且不做额外努力。基于栖息地适宜性指数，将地点分为三种类型：A（受保护且适宜，n = 3）；B（适宜但面临高灭绝风险，n = 9）；C（不适宜且动物种类极度匮乏，n = 75）。我们的结果表明，在情景1下，有可能资助一个积极的工作小组来改善B类和C类栖息地残余类型的森林质量，同时支持对A类地点的监测和保护。然而，在情景2下，如果没有成功的教育项目来提高认识并改变当地利益相关者的观念，几乎无法采取任何行动。本研究引入了一种空间指数，以便在关键地点优先开展保护行动，为在不断变化的环境中进行有效的资源管理提供了一种实用方法。面对资源限制以及日益受到威胁的生物多样性热点地区快速的环境和气候变化，我们的方案可能有助于指导保护行动。
