“Covered by an eternal fog cover, a mysterious and unknown world is located on the mountain’s abrupt slopes. Moisture is the key part of the intricate natural gear within this evergreen territory. Here, the rivers gain strength and descend eastward carrying mountain sediments with them. This land is one of crystal clear waterfalls and creatures as beautiful as orchids.” (2)




The vegetation is made up of a mix of herbs, bushes, and trees of poor quality. There are many thick-growing vegetative species, among them are ferns, rushes, and other ground covers. There are also many bushes, many of which protect the soil. They are small and thick, forming dense masses covered by epiphytes. 


Large tree species are scarce because of the altitude. The trunks grow to approximately 25 to 40 cms in diameter and they can reach 5 or 10 m in height. Most individuals have skinny trunks, they are short and deformed, and have small crowns that are sometimes partially dead. Epiphytes abound, almost the entire plant is covered. Mountainous forests prevail.    


Because of ecological variety, floristic composition is heterogeneous. Notable species from the Lauraceae family include oaks, walnuts and others, whose extraction is not profitable due to the area’s topography and the low volume of harvestable trees. 




Fauna registries for the protected area do not exist; however it is estimated that the principal species of the Peruvian Yungas Ecoregion are present in Pui Pui Protected Forest. The following lists probable animal families:

Mammals: Rats (Muridae), armadillos (Dasypodidae), opossums (Didelphidae), bats (Vespertilionidae, Molossidae), pumas (Felidae), ocelots (Felidae), deer (Cervidae), squirrels (Sciuridae), spectacled bear (Ursidae). Reptiles: lizards (Gymnophthalmidae, Iguanidae, Tropiduridae), vipers (Viperidae), snakes (Colubridae, Boidae). Amphibians: Toads (Bufonidae), frogs (Leptodactylidae).
