Tropical forest ecoregion
The Cuban moist forests is a tropical moist broadleaf forest ecoregion that occupies 21,400 km2 (8,300 sq mi; 5,300,000 acres) on Cuba and Isla de la Juventud . The ecoregion receives more than 2,000 mm (79 in) of rainfall annually, and does not have a dry season. Soils are usually derived from quartz , limestone , or serpentinites . Cuban moist forests can be differentiated into lowland forests (sea level to 400 m or 1,300 ft), sub-montane forests (400–800 m or 1,300–2,600 ft), and montane forests (800–1,900 m or 2,600–6,200 ft).[ 2]
Lowland forests
Lowland forests are found at elevations from sea level to 400 m (1,300 ft) and reach heights of 40 m (130 ft). They consist of three tree stories. The upper story includes achiotillo (Alchornea latifolia ), najesí (Carapa guianensis ) and acana (Manilkara valenzuelana ); the middle story has tagua-tagua (Diospyros caribaea ), Ocotea floribunda , Oxandra laurifolia , Talauma minor , Terminalia spp. and Ficus spp.; and the lower story has a number of species of tree ferns , Myrtaceae and Melastomataceae . Epiphytes are abundant and varied, including the endemic Hymenodium crinitum , Oleandra articulata , Columnea tincta , and Psychotria pendula . Typical palms are Calyptronoma plumeriana , Prestoea acuminata var. montana and Bactris cubensis . Heliconia species, mosses , and liverworts are also important plants.[ 2]
Sub-montane forests
Sub-montane forests occur elevations of 400–800 m (1,300–2,600 ft). Typical sub-montane forests consist of two tree stories and an understory ; they reach a height of up to 30 m (98 ft) in height. Achiotillo (Alchornea latifolia ), júcare amarillo (Buchenavia capitata ), purío prieto (Guatteria blainii ), Licaria jamaicensis , roble macho (Tabebuia hypoleuca ) and Zanthoxylum elephantiasis grow in the upper story. Cuaba de la maestra (Amyris lineata ), cuajaní (Prunus myrtifolia ), Ditta myricoides , Laplacea spp., Oxandra laurifolia , Ocotea spp., Rapanea ferruginea and Podocarpus species can be found in the lower story. Tree ferns , Myrtaceae and Melastomataceae and Rubiaceae flourish in the understory.
Sub-montane forests growing in ultisols reach a height of 20 m (66 ft) and have two stories with trees such as Calophyllum utile , Guatteria cubensis , Magnolia cristalensis , roble de hoja ancha (Tabebuia dubia ), Zanthoxylum cubense and Bactris cubensis .[ 2]
Montane forests
Montane forests are found at elevations of 800–1,900 m (2,600–6,200 ft). These forests consist of two arboreal stories and reach a height of 20 m (66 ft). The upper story is dominated by barril (Cyrilla racemiflora ), marañon de la Maestra (Magnolia cubensis ), Persea anomala and Laplacea angustifolia . The lower story consists of Cleyera nimanimae , Freziera grisebachii , Haenianthus salicifolius , Lyonia species, Torralbasia cuneata and enebro (Juniperus saxicola ). Epiphytes , mosses , ferns , terrestrial orchids , and clubmosses are abundant.[ 2]
Fauna
Birds of Cuba's moist forests include the Cuban tody (Todus multicolor ), bee hummingbird (Mellisuga helenae ), Cuban trogon (Priotelus temnurus ),[ 3] Cuban solitaire (Myadestes elisabeth ), Cuban kite (Chondrohierax wilsonii ), red-legged honeycreeper (Cyanerpes cyaneus ), Cuban parakeet (Aratinga euops ), Stygian owl (Asio stygius ) and Gundlach's hawk (Accipiter gundlachi ).[ 2] The rare Cuban solenodon (Atopogale cubana ), a small mammal , is endemic to the eastern montane forests along the Nipe-Sagua-Baracoa mountain range. Other notable mammals include the hutias , 4-5 species of small to medium-sized, climbing rodents related to the guinea pig .[ 3]
