SummaryThe preservation of Military Macaw Ara militaris in Mexico required the implementation of a nationwide assessment evaluating its vulnerability using IUCN criteria. With the combined effort of several institutions, the abundance, location, dispersion, habitat availability, and climatic conditions of areas occupied by the species were determined. Although the species’ extent of occurrence is extensive (263,919 km2) only 29% of this constitutes area of occupancy. Published estimates indicate a series of isolated populations containing from four macaws to 215. Macaws occurred in 35 populations in four regions of 16 states containing an estimated 1,563–3,263 macaws; lower than required for long-term viability. Within regions, neighbouring populations were separated by an average of 68 km. The extent of occurrence is heterogeneous, and macaws inhabit areas that differ in elevation, precipitation, temperature, and forest cover. Higher local abundances occur in landscapes where annual precipitation is ≥1,100 mm, and primary forest availability ≥1,800 km2. Although the existence of undetected macaw groups in Mexico is possible, these are likely to contain only small numbers of individuals, as most detected areas with macaws contain less than 40 individuals, and larger concentrations are more likely to be noticed due to their conspicuous behaviour. The species is threatened primarily by its low overall abundance, fragmented distribution, and forest loss around populations with the highest abundance. With the information generated, it is possible to design and implement specific management and conservation strategies at different geographic scales for the recovery and maintenance of the species in Mexico. It is necessary to strengthen collaborative programmes among conservation organizations, government agencies, and local communities in each region of the country to organize and finance community-based actions such as monitoring, habitat restoration, protection from poaching and the creation of a network of conservation corridors and macaw reserves focused on conservation.

评估墨西哥军用金刚鹦鹉种群的空间分布、丰度和保护前景

总结军用金刚鹦鹉的保存军蚁墨西哥要求实施一项全国性评估，使用 IUCN 标准评估其脆弱性。在多个机构的共同努力下，确定了该物种所占据区域的丰度、位置、分布、栖息地可用性和气候条件。尽管该物种的出现范围很广（263,919 km2) 其中只有 29% 构成占用面积。已发表的估计表明，一系列孤立的种群包含 4 到 215 只金刚鹦鹉。金刚鹦鹉出现在 16 个州的四个地区的 35 个种群中，估计有 1,563-3,263 只金刚鹦鹉；低于长期生存能力的要求。在区域内，邻近人口平均相隔 68 公里。发生的程度是异质的，金刚鹦鹉栖息在海拔、降水、温度和森林覆盖率不同的地区。在年降水量≥1,100 毫米、原始森林可用性≥1,800 公里的景观中，局部丰度较高2. 尽管在墨西哥可能存在未被发现的金刚鹦鹉群体，但这些群体可能只包含少量个体，因为大多数发现的金刚鹦鹉区域不到 40 只个体，而且由于它们的显眼行为，更容易注意到更大的浓度。该物种的主要威胁是其总体丰度低、分布分散以及丰度最高的种群周围的森林丧失。有了所产生的信息，就有可能在不同的地理范围内设计和实施具体的管理和保护策略，以恢复和维护墨西哥的物种。有必要加强保护组织、政府机构、
