Windsor Great Cave is
owned by WWF(UK).
It is approximately 3 km long and parts of it are still subject to water flows during heavy rains, so it is still active and being carved out of the limestone hills by water flow.
It is not generally realised that caves in limestone hills have a finite life as they migrate upwards through the hillside. This migration is caused by successive collapses of the ceiling due to the dissolution effects of water percolating downwards. Obviously, every time the ceiling collapses, the ceiling gets higher and the floor is raised by the debris: so the whole chamber gets higher.
Windsor Cave is an important roost for bats: a colony of at least 50,000 lives there and is responsible for the slippery "mud" that covers the floor. This bat guano used to be mined from deep in the cave during the '30's but carrying it out on your head is no longer viable! Windsor Research Centre has initiated a research project on these bats.
Any visitation to any cave with native fauna is a threat to the cave ecosystem because cave species tend to be very sensitive to the smallest microenvironmental changes, with a result that they are unable to adapt to changes and go extinct or, if possible, abandon the cave. Please read our brochure and consult the Cave Warden before entering the Cave.
HEALTH CAUTION FOR CAVE
EXPLORATION IN JAMAICA (Fincham 1997):
Histoplasmosis is a human fungal disease resulting from infection with the organism Histoplasma capsulatum, and is a potential hazard to anyone entering a tropical cave. Pulmonary histoplasmosis causes flu-like symptoms and, in severe cases, requires hospitalization. The fungus is considered common in Jamaican caves and is closely-linked with, but not exclusive to, cave-dwelling bats. A brief exposure is likely to result in infection. This was first recognized in 1978 when, a group of visitors were taken into a Jamaican cave; 25 of the 28 subsequently showed some symptom of the infection, including a woman and her son, aged 4yrs, who had remained at the cave entrance (Fincham 1978). Histoplasma spores may be present in dry guano piles even if the cave is no longer occupied by bats. Any persons known to be immunologically compromised should not expose themselves to the risk of histoplasmosis and all visitors to Jamaican caves should be aware that infection probabilities are high.
The entrance to Windsor Cave was formerly part of the Windsor estate: in the 1930's, it was exploited for guano and publicised for tourism by Willy Donald-Hill. The next owner, Miriam Rothschild, retained the Cave entrances when she sold Windsor in the 1950's and has donated this land to the World Wildlife Fund for Nature (WWF(UK)) in 1995.
