Tropical Climates and Ecosystems
2
The tropics are located between the Tropic of Cancer (23.4378 °N) and the Tropic of Capricorn (23.4378 °S) In this belt, the sun will be directly overhead at least once per year.

Areas where every month have mean temperatures above 18 °C (64 °F) are shown in blue below
11
Droughts may last for several months, and during this period trees will shed their leaves.

Habitats Forested habitats Submontane broadleaf forest Lowland broadleaf forest Submontane pine forest Lowland pine forest Mangrove and littoral forest Transitional habitats Scrub, low second growth Savanna (pine, oak, calabash, palmetto)
16
Other habitats Unforested habitats Anthropogenic Cities/towns, cultivated land, pastureland Wetlands with emergent vegetation Sedge savannas, wet meadows, marshes, ricefields
17
Submontane Broadleaf Forest The forest cover in most of the Maya Mountains, generally above 400 m (1300’) elevation Dominated by evergreen trees 25-35 m (80-115’) tall, typically with buttressed trunks Lots of epiphytes, lianas, substory dominated by tree ferns, palms, other shrubs Sparse understory vegetation
18
Lowland Broadleaf Forest Similar to, but less luxuriant than, submontane broadleaf forest Contains more dry- season deciduous tree species; significant leaf litter accumulates by end of dry season Not dominated by a tree species; may encounter dense stands of cohune palm Mahogany (Swietenia macrophylla), cedar (Cedrela mexicana), sapodilla (Manilkara zapota), ramon (Brosimum alicastrum), and figs (Ficus spp.) are common Trees are often >100 ft tall
19
Submontane Pine Forest Dominated by Caribbean pine (Pinus caribea) which require periodic low- intensity fires for regeneration Canopy may be closed, or semi- closed ~11% of Belize is covered by pines – 2% is closed canopy, 3% semi-closed, 6% savannah/lowland pine
20
Lowland Pine Forest Typically found in lowland areas with low nutrient soils Often soggy during wet season, very dry during dry season Ground cover dominated by grasses and sedges Tree species include Caribbean pine (Pinus caribea), calabash (Cresentia cujete), oak (Quercus spp.), craboo (Byrsonima crassifolia) and the plametto (Paurotis wrightii). “Forest” is a bit of a misnomer, as the canopy is not closed
21
Mangrove and Littoral Forest Only four species of mangrove in Belize Red mangrove (Rhizophora mangle) is the pioneer species, has stilt roots Black mangrove (Avicennia germinans) is found at the junction of water and land, has pneumatophores White mangrove (Laguncularia racemosa) and buttonwood (Conocarpus erecta) grow further inland Mangroves are the “nursery” of the sea
