The Central American pine–oak forests is a tropical and subtropical coniferous forests ecoregion in the mountains of northern Central America and Chiapas state in southern Mexico.[3]

Setting

[edit]

The Central American pine–oak forests occupy an area of 111,400 square kilometres (43,000 sq mi),[1] extending along the mountainous spine of Central America, extending from the Sierra Madre de Chiapas and Chiapas Highlands in Mexico's Chiapas state through the highlands of Guatemala, El Salvador, and Honduras to central Nicaragua.

The pine-oak forests lie between 600–1,800 metres (2,000–5,900 ft) elevation.[1] At lower elevations they transition to tropical moist forests on the Caribbean slope, and to tropical dry forests on the Pacific slope and interior valleys. Elevations above 1,800 metres (5,900 ft) are often covered with cloud forest ecoregions, including the Sierra Madre de Chiapas moist forests in the Sierra Madre de Chiapas, the Chiapas montane forests along the northern slope of the Chiapas Highlands, and the Central American montane forests in high-elevation enclaves from southern Guatemala to northern Nicaragua.

Flora

[edit]

The Central American pine–oak forests are composed mostly of pines (Pinus spp.) and oaks (Quercus spp.), with pines more abundant at higher elevations and oaks at lower elevations. Typical pines include Pinus chiapensis, Pinus tecunumanii, Pinus ayacahuite, and Pinus maximinoi. Typical oaks include Quercus corrugata, Quercus skinneri, Quercus oleoides, Quercus calophylla, Quercus acatenangensis, Quercus brachystachys, Quercus peduncularis, Quercus polymorpha, and Quercus acutifolia (syn. Quercus conspersa). American sweetgum (Liquidambar styraciflua) is often found among the oaks and pines.[1]

The Central American pine–oak forests are the southernmost extent of species from genera typical of temperate North America, including pine, fir (Abies guatemalensis), cypress (Cupressus lusitanica), ash (Fraxinus hondurensis and Fraxinus uhdei), and yew (Taxus globosa).[1]

Fauna

[edit]

Native mammals include jaguar (Panthera onca), puma (Puma concolor), ocelot (Leopardus pardalis), Baird's tapir (Tapirus bairdii), cacomistle (Bassariscus sumichrasti), greater grison (Galictis vittata), tayra (Eira barbara), Central American spider monkey (Ateles geoffroyi), mantled howler monkey (Alouatta palliata), and Mexican mouse opossum (Marmosa mexicana). They also include the bats Balantiopteryx io, Molossus aztecus, Macrotus waterhousii, Glossophaga leachii, Hylonycteris underwoodi, Carollia subrufa, Dermanura azteca, Dermanura tolteca, and Bauerus dubiaquercus. Native rodents include Liomys pictus, Microtus guatemalensis, Ototylomys phyllotis, Peromyscus aztecus, Reithrodontomys sumichrasti, and Scotinomys teguina.[1]

The mountains are designated an Endemic Bird Area, and are home to several limited-range and threatened species. Resident birds include the bearded screech owl (Megascops barbarus), fulvous owl (Strix fulvescens), ocellated quail (Cyrtonyx ocellatus), belted flycatcher (Xenotriccus callizonus), pink-headed warbler (Cardellina versicolor), black-capped siskin (Spinus atriceps), green-throated mountaingem (Lampornis sybillae), wine-throated hummingbird (Selasphorus ellioti), blue-throated motmot (Aspatha gularis), black-capped swallow (Atticora pileata), rufous-browed wren (Troglodytes rufociliatus), blue-and-white mockingbird (Melanotis hypoleucus), rufous-collared thrush (Turdus rufitorques), bar-winged oriole (Icterus maculialatus), and bushy-crested jay (Cyanocorax melanocyaneus).[1]

The pine–oak forests provide a winter home for several migratory species from temperate North America, including the golden-cheeked warbler (Dendroica chrysoparia) and azure-rumped tanager (Tangara cabanisi).[1]

Protected areas

11.67% of the ecoregion is in protected areas. Protected areas include:[2]
