Data supporting: Population Viability Analysis of the Western Chimpanzee (Pan troglodytes verus) in Loma Mountains National Park, Sierra Leone

“Population Viability Analysis of the Western Chimpanzee (Pan troglodytes verus) Population of Loma Mountains National Park, Sierra Leone, West Africa.” The repository contains the primary quantitative inputs and demographic parameters used to conduct the Population Viability Analysis (PVA) implemented in VORTEX v10.6.0. Files included: LMNP_Chimpanzee_Transect_Data.xlsxThis file contains the empirical population and survey data used to inform baseline population size estimates and contextualize demographic trends in Loma Mountains National Park (LMNP). Variables include transect-derived estimates and related field-based population metrics. LMNP_Chimpanzee_PVA_Model_Parameters.xlsxThis file contains the demographic and anthropogenic parameters used to parameterize the VORTEX simulations, including: Age-specific mortality rates Reproductive parameters Initial population structure Hunting pressure assumptions and multiplier-based extraction estimates Deforestation and habitat change scenarios Catastrophic disease assumptions All parameter values, assumptions, sources, and ranges correspond to those reported in the manuscript tables and methodology section. These files provide full transparency regarding the demographic assumptions and threat scenarios used to simulate population trajectories under baseline and alternative management scenarios. The simulations were conducted over a 50-year time horizon with 100 iterations per scenario. Extinction was defined as the loss of either sex within the population. No sensitive location data or individual-level identifiers are included in this dataset.西非塞拉利昂洛马山脉国家公园西部黑猩猩（Pan troglodytes verus）种群生存力分析（Population Viability Analysis, PVA） 本数据集仓库包含了用于开展种群生存力分析的核心量化输入数据与种群人口统计学参数，该分析依托VORTEX v10.6.0软件实现。 包含文件如下： LMNP_Chimpanzee_Transect_Data.xlsx：该文件收录了用于推导洛马山脉国家公园（LMNP）基准种群规模估算值、并辅助解读种群人口统计学趋势的实证种群与野外调查数据，变量涵盖基于样线调查得到的种群估算值及相关野外种群统计指标。 LMNP_Chimpanzee_PVA_Model_Parameters.xlsx：该文件包含用于配置VORTEX模拟模型的人口统计学与人为活动参数，具体包括： 1. 年龄特异性死亡率； 2. 繁殖参数； 3. 初始种群结构； 4. 狩猎压力假设及基于乘数的种群提取估算值； 5. 森林砍伐与栖息地变化情景； 6. 灾难性疾病假设。 所有参数取值、假设条件、数据来源及取值范围均与对应论文的表格及方法章节中报告的内容完全一致。 本数据集完整披露了用于模拟基准情景与替代管理情景下种群动态轨迹的人口统计学假设与威胁情景。 本次模拟实验以50年为时间跨度，每个情景执行100次迭代。种群灭绝被定义为种群内任一性别的个体完全消失。 本数据集未包含任何敏感位置信息或个体层面的识别数据。
