During a 2012 Chicago Field Museum RAPID study in the Kampankis a species inventory found:
Plants 1,100, Fishes 60, Amphibians 60, Reptiles 48, Birds 350, Mammals 73.

The Kampankis Mountains are well described in the geologic literature. They are
composed of continental and marine deposits that range in age from the Jurassic
(160 million years old) to the Neogene (5 million years old) and include eight geologic formations in which varieties of sandstone, limestone, and siltstone predominate.
The vegetation of the Kampankis Mountains varies with geology and elevation. Five primary vegetation types have been defined in the Kampankis areas: 1) riparian vegetation along streams and rivers; 2) lower hill forests between 300 and 700m elevation, on sandy to clayey soils; 3) mid-elevation forests at 700–1,000m, on sandy to clayey soils; 4) forests on limestone outcrops and associated soils, between 700 and 1,100m; and 5) low forests on sandstone outcrops and associated soils on the highest slopes and ridges of the range, at 1,000–1,435m elevation.
The Kampankis avifauna is a diverse mix of lowland Amazonian and Andean foothill bird communities. Through field observations and recordings, the ornithological team registered 350 bird species, of which 56 are typically montane.
Several rare and little-known species recorded during the inventory—like Leucopternis princeps
, Wetmorethraupis sterrhopteron
, and Entomodestes leucotis
— are known from very few sites in Peru.
Mammals: 57 of the 79 species of medium-sized and large mammals believed to occur in the area include:
White-bellied spider monkey Ateles belzebuth (Endangered), Common woolly monkey Lagothrix lagotricha, Juruá red howler monkey Alouatta juara, White-tailed Titi monkey Callicebus discolor, Saddleback tamarin Saguinus fuscicollis, Saki monkey Pithecia aequatorialis, Owl monkey Aotus vociferans, Tayra Eira barbara, Jaguar Panthera onca (near threatened), Puma Puma concolor, Short-eared dog Atelocynus microtis (near threatened), Tapir Tapirus terrestris (Vulnerable), Giant armadillo Priodontes maximus (Vulnerable), Giant anteater Myrmecophaga tridactyla (Vulnerable), River otter Lontra longicaudis, Tamandua Tamandua tetradactyla, Chestnut sac-winged bat (Wagner's sac-winged bat) Cormura brevirostris (Rare), and Lesser Long-tongued Bat Choeroniscus minor which prefers undisturbed forests.
UPDATE: An establish tribe of the Peruvian Red Uakari Monkey, Cacajao calvus ucayalii (Vulnerable), has been confirmed in an area ~34mi/55km SSE of Sawi Entsa near the settlement of Candamo (05°31′S 077°39W′; altitude 1,421 m a.s.l.). The Peuvian Red Uakari is an Amazonian primate with peculiar features; it has a bright red, bald face, a short tail, and ruddy fur. This monkey is highly specialized and is found mainly in palm tree habitats. This population is isolated from the other known uakari populations in the eastern lowlands, which raises questions concerning their taxonomic status and biogeographical history.
