The Rio Abiseo National Park is located in the San Martín department of Peru. UNESCO pronounced it as Natural and Cultural Heritage of Humanity (World Heritage Site) in 1990. The park is home to a large number of species of flora and fauna, as well as the location of over 30 pre-Columbian archaeological sites. Since 1986, the park has not been open to tourism due to the fragile nature of both the natural and archaeological environment.

[edit] Geography and climate

Located in the San Martín Region of Peru between the Marañón and Huallaga rivers, the park has an area of approximately 2,745.2 square kilometres. The park covers 70% of the Abiseo river basin. Elevations reach as high as 4,200 meters (13,780 ft) above sea level and as low as 350 m (1,150 ft).

There are at least seven climate zones in the park, including montane forest, tropical alpine forest, montane rainforest, high Andean grasslands (puna), and dry forest. Rainfall ranges from 20 to 80 inches per annum. The montane cloud forest, composing most of the park area, is a high-altitude rainforest with short trees, moss and lichen. This ecosystem occurs above the altitude of about 2,300 meters (7,550 ft). High humidity is constant and rain falls throughout the year, particularly at the higher elevations. The soil is acidic.

[edit] Wildlife

The Yellow-tailed Woolly Monkey (Oreonax flavicauda), previously thought to be extinct, is known to live in the park and appears to be endemic to the region. It was mostly due to this monkey's critically endangered status that the area gained national park status and was placed on the list of World Heritage Sites in 1983.

Other fauna in the park includes:

Andean guan, Penelope montagnii
Venezuelan Red Howler, Alouatta seniculus
White-fronted Spider Monkey, Ateles belzebuth (endangered)
Jaguar, Panthera onca
King Vulture, Sarcoramphus papa
Three-striped Night Monkey, Aotus trivirgatus
Curassaw, Crax salvini
Peruvian Guemal, Hippocamelus antisensis (endangered)
Mountain paca or Punatuacher, Agouti tazcanowskii (endangered)
Southern Pochard duck, Netta erythrophthalma
Spectacled bear, Tremarctos ornatus (endangered)
Turkey vulture, Cathartes aura
White-fronted Capuchin, Cebus albifrons cuscinus
Yellow head parrot, Amazona ochrocephala
Russet-mantled softtail, Phacellodomus berlepschi (endangered)
Yellow browed Toucanet (endangered)

There are 980 known species of plants documented in the highlands of the park, 13 of which are endemic, and 5000 species of plants in the area of the Rio Abiseo.

[edit] Archaeology

The largest and most well-known archaeological site in the Rio Abiseo park is Gran Pajáten, a Chachapoyas ruin located at the crest of a hill near the border of the San Martín region. Nearby are the ruins of Los Pinchudos (discovered by a villager from Pataz in 1965), a series of cliffside stone tombs. Much of the archaeological work done in Rio Abiseo Park is led by the University of Colorado.
