Chocolate lowland climate in the narrow band of latitudes where cacao is grown (20 degrees north and south of the equator), the commercial company Mars, Incorporated and the University of California, Berkeley are conducting genomic research in 2017–18 to improve the survivability of cacao plants in hot climates. Chocolate is made from cocoa beans, the dried and fermented seeds of the cacao tree ("Theobroma cacao"), a small, 4–8 m tall (15–26 ft tall) evergreen tree native to the deep tropical region of the Americas. Recent genetic studies suggest the most common genotype of the plant originated in the Amazon basin and
Flora of Belize cleared, although clearing of mangroves near Belize's main coastal settlements (e.g. Belize City and San Pedro) was relatively high. The rate of loss of Belize's mangroves - at 0.07% per year between 1980 and 2010 - was much lower than Belize's overall rate of forest clearing (0.6% per year between 1980 and 2010). As well as logwood ("Haematoxylon campechianum") and mahogany ("Swietenia macrophylla") two other important Belizean timber trees of note are the Santa Maria ("Calophyllum antillanum") and cedar ("Cedrela mexicana"). Other economically important trees include cotton tree or kapok (Ceiba pentandra), and cacao (Theobroma cacao). Chicle (Manilkara chicle) is
