Background

Karst Topography

The Cockpit Country is a rugged, forested area of western Jamaica, rich in biodiversity and cultural heritage. The area encompasses the largest remaining intact wet limestone forest in Jamaica, which is of outstanding ecological importance to the island. Its landscape of steep-sided hills and deep, round valleys eroded from the limestone bedrock is the world’s most outstanding example of karst topography.

This reservoir of globally significant natural and cultural resources has been earmarked for bauxite mining by the local subsidiary of the multi-national minerals company, ALCOA.

Due to its remoteness and inaccessibility, most of the Cockpit Country has been insufficiently studied. Each scientific expedition reveals more of the natural wonders of this ‘biodiversity hotspot’ and the secrets of its human history.

Biodiversity

Blackbill ParrotThe wildlife of the Cockpit Country is specially adapted to this unique environment, and numerous species of plants and animals occur here that are found nowhere else in the world: they are endemic not only to Jamaica, but to the Cockpit Country itself. Indeed, the concentrated biodiversity of this an island-within-an-island is considered to be of global significance.Jamaican-Kite-Butterfly

The area is home to perhaps the only viable population of the endangered, endemic Giant Swallowtail butterfly; with a wingspan of up to 8 inches (20 cm) it is the largest butterfly in the Americas.

Many of Jamaica’s threatened birds are found here, including the critically endangered Jamaican Blackbird and both species of Jamaica’s endemic parrots. Almost the entire population of the Black-billed parrot (95 percent) is found in the Cockpit Country. The illegal capture of Jamaican parrots for the pet trade threatens their survival in the wild.

Four of Jamaica’s 14 endemic frogs occur only in the forests and caves of the Cockpit Country, by far the most important area of habitat for Jamaica’s amphibians and reptiles.

Unique in the world is a species of crab that inhabits the water at the base of bromeliad leaves in limestone forests such as those of the Cockpit Country.

Taino Frog DrawingCultural resources


 Although much of the Cockpit Country remains unexplored, there are a number of known sites of Taino occupation. The zoomorphic art of the Taino reflects their reverence for the natural world, on which they depended. For example, the frog was a Taino fertility symbol. The drawing at right is inspired by a Taino pictograph.

The Cockpit Country is renowned in Jamaican history as the refuge of the fiercely independent Maroons, descendants of the earliest slaves who were freed by the Spanish settlers around the time of the British conquest in 1655. After almost a century of resistance to British rule in the ‘Land of Look Behind’, the Maroons forced the British into signing a peace treaty in 1738.

Geology and Hydrology


Cockpit Country is recognized internationally as the ‘type locality’ for cockpit karst – a term given to limestone bedrock that has been dissolved and eroded by rain over millions of years. It has taken over 15 million years for Jamaica’s Cockpit Country to be created in this way. Cockpits, the bowl-shaped valleys, average in depth from 100 to 120 metres, with walls generally sloping from 30 to 40 degrees. Drainage of the cockpit bottoms occurs via percolation or by sinkhole.

The municipal and agricultural water supply for much of western and northern Jamaica is dependent on the input of groundwater from Cockpit Country sources. The headwaters of a number of the island’s major rivers are found within the Cockpit Country, including the Martha Brae to the north, the Hector’s River and Black River systems to the south, and the Rio Bueno to the east. The Quashie’s River sink at Freeman’s Hall (within the prospecting licence area) is one of the sources of the Dornoch Head Rising near Stewart Town, which flows to the sea as the Rio Bueno.

The hydrology of the area is not yet thoroughly understood and further research is needed to trace the vast subterranean network connecting the caves, sinks and risings of the Cockpit Country.
