Using camera traps, we recorded presence of the white-lipped peccary (Tayassu pecari; WLP) in the Chenkan region, an area of wetlands, mangroves, and tropical flood forest located on the coast of Campeche in Mexico. The WLP had been considered extinct in the area, so its rediscovery in Chenkan increases the known range of the current distribution of this species, which is classified as endangered in Mexico. The presence of WLP in Chenkan highlights the importance of the area for the conservation of this endangered species. Therefore, it is necessary to take effective conservation actions to maintain the region's natural ecosystems, which are under strong pressure from expanding agriculture and tourism infrastructure.
