This study outlines the procedures used for collecting, processing, and categorizing data on 16 new mammal species for mainland Portugal, belonging to four taxonomic groups: Eulipotyphla (1), Chiroptera (4), Rodentia (2), and Cetacea (9). Data collection and processing encompassed field and lab work and bibliographic compilation. Data categorization involves, whenever possible, the assessment of the approximate number of mature individuals in populations, the extent of occurrence, and the area of occupancy. The approach employed led to the classification of eight out of the 16 species into an IUCN category: two non-volant small mammals and one bat species were designated as Vulnerable, requiring ongoing monitoring; one rodent and three cetaceans were assigned to Data Deficient due to insufficient available information; and a single bat species was classified as Least Concern due to the high abundance of local populations. For small mammals and bats, alterations to natural systems and climate change emerged as the most relevant threatening factors, while for cetaceans, human activities such as fishing, commercial shipping, and tourism were identified as the primary survival risks. It is recommended to maintain action programs that assist in defining strategic orientations for the implementation of conservation measures on a case-by-case basis.
本研究概述了为葡萄牙大陆16种新哺乳动物物种收集、处理和分类数据所采用的程序，这些物种属于四个分类群：食虫目（1种）、翼手目（4种）、啮齿目（2种）和鲸目（9种）。数据收集和处理包括野外和实验室工作以及文献编纂。数据分类尽可能涉及对种群中成熟个体的大致数量、分布范围和占用面积的评估。所采用的方法导致16个物种中的8个被列入世界自然保护联盟（IUCN）的类别：两种非飞行小型哺乳动物和一种蝙蝠物种被指定为易危物种，需要持续监测；一种啮齿动物和三种鲸类动物由于现有信息不足而被列为数据缺乏；由于当地种群数量众多，一种蝙蝠物种被归类为无危物种。对于小型哺乳动物和蝙蝠，自然系统的改变和气候变化是最相关的威胁因素，而对于鲸类动物，捕鱼、商业航运和旅游等人类活动被确定为主要生存风险。建议维持行动方案，以协助逐案确定实施保护措施的战略方向。
