Limestone Karst Ecosystems by Toby Smith

Limestone karst formations and ridges are often ancient geological islands or ‘arks’ – the final remnants of much wider limestone deposits that have long since eroded away. They therefore contain high-levels of plant and animal micro-endemism (restricted to a single small site) both on the surface and also beneath the surface in cave systems.
