  Windsor Great Cave is a 3,000 metres (9,800 ft) long cave in Trelawny Parish on the north coast of Jamaica. The land external to the main entrance is owned by the WWF (UK), and access is often denied by the Windsor Research Centre who act as their proxy.
  
  ## Natural history
  
  The caves contain a major bat roost that hosts 12 or so species including Mormoops blainvillii, Pteronotus parnellii, Glossophaga soricina, Artibeus jamaicensis and Ariteus flavescens. Bat guano has been harvested from the caves for many years and this continues.
  
  Invertebrates include springtails of the species Troglopedetes jamaicanus, fungal gnats, troglobitic spiders (Nesticidae), larval Neodytomyia farri and the invasive roach Periplaneta americana.
  
  Stygobites include cave-adapted crabs of the species Sesarma verleyi, but note that the misnamed Sesarma windsor is not found here.
  
  ## Palaeoclimatic records
  
  In the main bat roost there is a mound of guano over two metres high, directly under a particularly good roosting-spot. The deeper strata of this deposit may record the climate of the island for periods that could extend back for thousands of years.
