Little is known about the conservation status of jaguar and white-lipped peccary populations west of the Andes in Ecuador. We surveyed the two species in the four largest forest remnants in western Ecuador, using interviews to local people, reconnaissance surveys, and camera traps. The two species were detected only in one of the remnants (Cotacachi-Cayapas Ecological Reserve and its buffer zone, an area of 2,500 km2). It appears, both species have been extirpated already from the other three large forest remnants in the region, and their long-term persistence depends on immediate conservation actions in Cotacachi-Cayapas Ecological Reserve.
