What impact does karst geology have on the ecosphere?
One of the obvious results of karst formations is the unique cave habitats which may be created. Caves have been explored and used by humans for centuries, but we are only recently appreciating how rich the cave fauna is. Caves are widely used as hibernacula (hibernation sites) for bats in temperate areas and may be important refugia for endangered species. A survey of the Blue River Basin Caves in 1993 revealed that these caves hosted 127,000 bats, more than one third of the known population. Surveys of caves in the US are continually finding new invertebrate species, especially arthropods.
The effects of karst geology reach beyond the caves into the surface features of karst landscapes. One of the striking features of many karst landscapes is the absence of surface water. Streams rapidly sink into the subsurface through the limestone fissures, sinkholes etc. This process produces unique communities which have evolved over long periods of time. The rapid run-off and sinking of water in karst lands has also had a dramatic effect on the ecology of one of the more recent inhabitants of the karsthumans.
