COCKPIT COUNTRY :
Cockpit Country Protected Area (CCPA) . . .
Disconnects Underground Hydrology

Parrot

On pages 7-8 of the Prime Minister's speech, he noted that cave openings were used as a proxy for the hydrology of Cockpit Country's karst limestone aquifer. The use of caves is helpful because an opening can often (but not always) lead to a water-filled, subterranean passage.

The many cave openings shown on the map, however, only give a static representation of what is, in fact, a dynamic system of water moving through the aquifer. A better representation of Cockpit Country hydrology is to include the proven underground flows, descriptions of which have been available from the peer-reviewed literature since the 1970s* and presented in Dr. Alan Fincham’s registry of caves (Jamaica Underground: The Caves, Sinkholes and Underground Rivers of the Island). Additional information about the hydrology of western Cockpit Country is provided by endemic freshwater crabs – their DNA tells us which populations are sharing their genes and which populations remain isolated.

As revealed by proven underground flows, the (Proposed Boundary) of the Cockpit Country Protected Area (CCPA) does not protect the underground hydrology of Cockpit Country.
