Cordillera Central Páramo

The Cordillera Central páramo (NT1004) is an ecoregion containing páramo (high moorland) vegetation above the treeline in the Andes mountain range of northern Peru and southern Ecuador. Due to its isolation there are high levels of endemism. Despite many human settlements and some destruction of habitat by agriculture and mining, the ecoregion is relatively intact.

Geography

Location

The Cordillera Central páramo is found in the upper regions of the Andes in northern Peru and southern Ecuador.
The ecoregion has an area of .
The páramo covers ridges and mountains in the high basins of the Piura and Cajamarca regions of Peru and in the south of Ecuador.
The northern part of the ecoregion is surrounded by the Eastern Cordillera Real montane forests ecoregion.
Further south it adjoins or is surrounded by Tumbes–Piura dry forests, Marañón dry forests, Peruvian Yungas, Ucayali moist forests, Sechura Desert and Central Andean wet puna.

Terrain

The Cordillera Central páramo begins at the treeline around of elevation and extends upward to the permanent snowline at about .
Some mountains are volcanic in origin from the Tertiary period, but there are also Paleozoic metamorphic and sedimentary rocks, Paleocene batholiths and areas of Precambrian rock.
Terrain includes steep slopes on the high peaks, and flat or rolling tablelands cut by deep valleys in which the climate is milder.
Soils are wet or marshy, with rocky regions and rock outcroppings.
The páramo is the source of many streams that run down the east and west slopes of the Andes and provide an important source of water to the human populations lower down.
In Peru it supplies the Quirós, Huancabamba and Chinchipe rivers.

Climate

The Köppen climate classification is "Cfb": warm temperate, fully humid, warm summer.
The climate is cold, wet and very cloudy, with high rainfall.
Temperatures generally fall below freezing at night.

Ecology

The Cordillera Central páramo ecoregion is in the neotropical realm, in the montane grasslands and shrublands biome.
The wet shrublands are the most southern group of páramos in the Neotropical realm.
The great Huancabamba Depression lies to the south of the ecoregion, a barrier that prevents flora and fauna from migrating between the north and south Andes mountains.

The ecoregion is part of the Northern Andean Páramo global ecoregion, which includes the Cordillera Central páramo, Santa Marta páramo, Cordillera de Merida páramo and Northern Andean páramo terrestrial ecoregions.
The plants and animals are adapted to the cold, dry conditions of the high peaks.
There is a high level of local endemism, particularly on the more isolated peaks.
Part of the Cordillera Central páramo has been identified as a hotspot, a threatened area with a high level of endemism.
Other hotspots in Peru include the Marañón dry forests, central Peruvian Yungas and central Andean puna.

Flora

Vegetation includes tussock grasses and cushion plants, shrubs and sedges, often with an under-layer of lichens and moss.
The lower levels of páramo merge into dwarf transitional forest and montane cloud forest.
The characteristic vegetation consists of plants of the genera ''Calamagrostis'', ''Agrostis'' and ''Hypericum'',
There are also shrubs of genera such as ''Polylepis'' and ''Escallonia''.
The isolated position of the páramos has resulted in high levels of endemism among the diverse plant species.
There are 300 genera of spermatophytes with 1,000–1,500 species, of which about 60% are endemic.
Notable species of flora include ''Cinchona officinalis'' and '' Schmardaea microphylla''.

Fauna

The fauna of the plateau include species that originated from the Amazon basin, from the tropical Andes and from the northern desert areas.
Mammals include mountain tapir (''Tapirus pinchaque''), little red brocket (''Mazama rufina''), spectacled bear (''Tremarctos ornatus''), northern pudú (''Pudu mephistophiles'') and small-eared shrews (genus ''Cryptotis'').
The mountain tapir (''Tapirus pinchaque'') is endangered.
The ecoregion has three endemic bird species.
Endangered birds include the bearded guan (''Penelope barbata'') and red-faced parrot (''Hapalopsittaca pyrrhops'').
The rufous-breasted warbling finch (''Poospiza rubecula'') is also endangered.

Other fauna include the Huancabamba whorltail lizard ('' Stenocercus huancabambae''), the frogs '' Astrotheca galeata'', '' Gastrotheca lateonata'', '' Lynchius parkeri'', '' Gastrotheca nebulanastes'' and genus ''Eleutherodactylus'' and butterflies of the genera ''Dismorphia'', ''Pagyris'' and ''Veladyris''.
Endangered amphibians include '' Atelopus peruensis'', ''Hyloxalus elachyhistus'', '' Lynchius parkeri'', '' Pristimantis simonsii'', '' Telmatobius brevipes'', '' Telmatobius degener'' and '' Telmatobius thompsoni''.

Status

The World Wildlife Fund gives the ecoregion the status "Relatively Stable/Intact".
The ecoregion has been used by humans for many years, with many settlements and highways crossing the plateau, but is still fairly intact,
A recent expansion of the human population and increase in agriculture is destroying the habitat around settlements.
Overgrazing by livestock is causing erosion of the soil.
Mining waste sometimes contaminates the rivers.
Protected areas include the Podocarpus National Park.
