These are primary forest with broadleaf trees at least 5 m tall and interlocking crowns, ie, a closed canopy. They show minimal human disturbance and are rich in flora biodiversity. They also provide habitat for a host of animal species, many of which are endemic to Jamaica. closed broadleaf forests Closed broadleaf forest in the Cockpit Country. Typical species found in the Closed Broadleaf forests of the Blue Mountains include Soapwood (Clethra occidentalis), above right, and Galimenta Bullet (Pouterial multiflora), above left, while common species in the Cockpit Country are White Olive (Terminalia arbuscula), Broadleaf (Terminalia latifolia) and Burn Eye (Sapium cuneatum). There are approximately 88,000 hectares of closed broadleaf forest remaining, representing about 8% of Jamaica's total land mass. Of this, nearly 65,000 hectares have been declared forest reserves with protected status under the Forest Act, 1996. The largest continuous areas of these forests are found in the Blue Mountain Forest Reserve, which encompasses both the Blue and John Crow Mountains, and in the Cockpit Country Forest Reserve. The soils of the Blue Mountains are acidic, being derived from volcanic rocks, hence its forests are distinct from those growing on the alkaline limestone soils of the John Crow Mountains and Cockpit Country. Smaller pockets of closed broadleaf forest are found in the Dry Harbour and the Dolphin Head Mountains, both of which are forest reserves. These areas are no less rich in biodiversity, for example, over 570 species of vascular plants have been identified in the Dolphin Head of which 162 are endemic to Jamaica, and more than 20 are found nowhere else in Jamaica.
