Biodiversity<br />

Biodiversity refers to <strong>the</strong> variety and abundance <strong>of</strong> life forms in a particular<br />

place or ecosystem. Biodiversity comprises flora (plants) and fauna (animals).<br />

Indigenous species are plants and animals that naturally occur in a particular<br />

country but may also be found elsewhere in <strong>the</strong> world. An endemic species is<br />

any kind <strong>of</strong> plant or animal that is found only in a particular area (usually<br />

refers to a country). For a small island, Jamaica has a relatively large number<br />

<strong>of</strong> endemic species <strong>of</strong> flora and fauna – species that are found nowhere else in<br />

<strong>the</strong> world.<br />

Examples <strong>of</strong> biodiversity include flowering plants such as grasses and<br />

palms, orchids, cacti and ferns, and fauna including mammals, birds, reptiles,<br />

amphibians, fish and invertebrates.<br />

Flora<br />

Jamaica is well known for its many species <strong>of</strong> flowering plants and ferns, more<br />

than four hundred <strong>of</strong> which are considered threatened or endangered due to<br />

clearing <strong>of</strong> land and o<strong>the</strong>r changes in habitat or over-harvesting. Flowering<br />

plants include numerous species <strong>of</strong> orchids, bromeliads, cacti, palms, trees,<br />

vines, shrubs and grasses. Approximately 30 per cent <strong>of</strong> <strong>the</strong> island’s flowering<br />

plants are endemics. Indigenous plants include <strong>the</strong> national flower, <strong>the</strong> lignum<br />

vitae (Guaiacum <strong>of</strong>ficinale), pimento (Pimenta dioica), pawpaw or papaya<br />

(Carica papaya), sweet potato (Ipomea batatas), pineapple (Ananas comosus),<br />

cassava (Manihot esculenta) and guava (Psidium guajava). Many <strong>of</strong> <strong>the</strong> island’s<br />

most familiar and useful plants have been introduced since European colonization<br />

in <strong>the</strong> sixteenth century. Introduced plants include ackee (Blighia sapida),<br />

breadfruit (Atrocarpus altilis), coconuts (Cocos nucifera), mangoes<br />

(Mangifera indica), bananas and plantain (Musa spp.) and a great many ornamental<br />

plants used in horticulture. <strong>The</strong> latter include hibiscus, bougainvillaea,<br />

oleander, anthuriums, and poinsettia. Many introduced plants have become so<br />
