Inventory of medium-sized and large mammals in La Encrucijada Biosphere Reserve and Puerto Arista Estuarine System, Chiapas, Mexico

La Encrucijada Biosphere Reserve (REBIEN) and Puerto Arista Estuarine System (SEPA) are natural protected areas and Ramsar sites in Chiapas, Mexico. In this study, we conducted an inventory of medium-sized and large mammals using camera trapping. We recorded 23 species in the REBIEN and 13 species in the SEPA. In addition, 35% of the species recorded in the two sites are at some category of risk of extinction at the national or international level. The most abundant species in the REBIEN were Northern Raccoon (Procyon lotor (Linnaeus, 1758)) and White-Nosed Coati (Nasua narica (Linnaeus, 1766)). In the SEPA, White-tailed Deer (Odocoileus virginianus (Zimmermann, 1780)), Collared Peccary (Dicotyles crassus (Merrian, 1901)), and White-Nosed Coati (Nasua narica). Our results highlight the importance of both study sites in the conservation of medium-sized and large mammals and underline the urgent need to develop conservation strategies for these areas
