Manu National Park was established by decree on 29 May 1973; during the dictatorship of GeneralJuan Velasco.[1][2] In 1977,UNESCO recognised it as aBiosphere Reserve and in 1987, as aWorld Heritage Site.[1] In 2002, the Peruvian government increased the extension of the park to its current area.[3]
Manu National Park covers an area of 1,716,295.22 hectares (17,162.95 km2) which comprises mountainous areas (traversed by creeks and valleys) with elevations close to 4000 m above sea level and a portion of the Amazon Basin plains.[1]
The national park is divided in the following areas: the restricted use zone (with pristine forests and native communities, access is granted to researchers only); the reserved zone (for recreation and research); the recuperation zone (for the recovery of disturbed areas) and the cultural zone (for human settlement and most activities including nature tourism).[4][5]
The 190 kilometres (120 mi) Manu road is the only link between the highlands of the park and the lowlands where the mouth of theManu River is located.[6]
Climate in the park is highly variable, with the amount of rain depending on the elevation.[1] The southern section (mountainous) has an annual precipitation between 1500–2000 mm; while in the middle section it is between 3000–3500 mm and in the northwestern section the annual precipitation reaches 8000 mm or more.[1] The less rainy season is from May to September, accompanied by lower temperatures.[1]
In the park, the mean annual temperature in the lowland rainforest is 25.6 °C, while in the Andean zone it is 8 °C.[1]
Vegetation types inside the park includepuna grassland (in areas over 4000 m), high Andean forests,cloud forests and lowlandAmazon rainforest.[1] This variety of vegetation types is represented in 162 families, 1191 genera and 4385 identified species of plants, with as much as 250 tree species in one hectare.[1] A study found a total of 1108 species of trees inside the park, from several plots between the mountain tree line and the lowland forest.[7]
In 2021, the so-called “Manu Mystery Plant”, a small tree, with tiny white flowers and ribbed, bright orange fruit, was determined to be a distinct genus, which was named Aenigmanu (the enigma of Manu). The plant, first collected in 1973 byField Museum ecologistRobin Foster, had puzzled experts for decades. DNA analysis revealed it to be related to thePicramniaceae; but unlike this family, the Aenigmanu hasstipules on its stems where the leaves emerge.[9]
In addition, 210 species of fish, 300 species of ants, 650 species of beetles, 136 species of dragonflies and more than 1300 species of butterflies have been reported in the park so far.[1]
There are five areas open to tourists where local biodiversity can be watched along paths, swamps,oxbow lakes and river shores.[1] In the lower basin of Manu river there are also: 5 camping sites, 4viewing points (one of them an 18 m tower), 3 lodges and acanopy walkway.[1]
Scientific research is also done at the park, with many research centers in or around the area.[1]
