The Tamá Massif (Spanish; Castilian: Macizo del Tamá) is a group of mountains on the border between Colombia and Venezuela to the south of Lake Maracaibo. It contains evergreen rainforest and cloud forest at the lower levels, and páramos (high moors) at the highest levels.
The Tamá is a prolongation of the Cordillera Oriental of the Colombian Andes.It is separated from the Cordillera de Mérida in the Venezuelan Andes by the Táchira depression, which more than 50 million years ago was a strait that connected Lake Maracaibo with the Orinoco basin.Elevations range from 320to.Average annual temperature is . Average annual rainfall is .The Tamá National Natural Park in Colombia and the El Tamá National Park in Venezuela protect parts of the Tamá Massif.The two parks together form a protected area of 1390km2.
The Tamá massif is a set of folded mountain ranges with extremely steep topography.It contains the El Tamá páramos (high moors) at an elevation of, Cerro El Cobre at and Cerro Judío at .The mountains are mainly of limestone or sandstone rock, typical of the Guiana Shield.The Tamá National Natural Park contains an 820adj=midNaNadj=mid waterfall one of the world's highest.The páramos give rise to rivers such as the Carapo, Chiquito, Quinimarí, Quite, Burguita, Burga, Nula, Nulital, Sarare, Cutufí, Oirá, Frío and Negro, which drain into the Orinoco basin or into Lake Maracaibo.The Táchira River, which drains into Lake Maracaibo, forms part of the border between Colombia and Venezuela.
Tamá has four types of natural environments: tropical rainforest, sub-Andean forest, Andean forest and páramo.The forests are included in the Venezuelan Andes montane forests ecoregion, which also covers the Venezuelan Andean cordillera.The vegetation between 800and is dense evergreen rainforest of medium height with two or three arboreal strata. There is a well-developed understory and many epiphytes.Forest species include the colorful Lagenanthus princeps.In the páramos the plant species are of the genera Jamesonia, Oreobulus, Castilleja, Gentiana, Halenia, Pinguicula, Utricularia, Castratella and Vaccinium.
Mammals include the spectacled bear (Tremarctos ornatus), tapir, lowland paca (Cuniculus paca), anteater and ocelot (Leopardus pardalis).The endemic wood sprite gracile opossum (Gracilinanus dryas) and Luis Manuel's tailless bat (Anoura luismanueli) are found in both the Andean Cordillera and the Tamá Massif.Restricted range bird species in the Tamá massif include Táchira antpitta (Grallaria chthonia), hooded antpitta (Grallaricula cucullata) and Venezuelan wood quail (Odontophorus columbianus).Tamá harlequin frog and Helena's marsupial frog are endemic to the Páramo de Tamá.
