On Tuesday December 16th at 8pm est, 7pm cst and 5pm pst, we are excited to be welcoming Dave Foster, Executive Director of the ACCA, to Natures Talk Show to discuss cave conservation. We will learn some fascinating details of cave ecosystems and groundwater issues. There are amazing animals and plants that have evolved in cave conditions. Created on An Ecological Mandate

ACCA is concerned with all caves, regardless of their mode of origin or location. However, most caves are found in the earth's more water-soluble rocks such as limestone, dolomite, marble and gypsum.  The lands in which these types of caves are found are called karst or karstlands.  

In karst, there is appreciable groundwater movement through dissolved-out  openings in the bedrock; karstlands often have features such as sinkholes, sinking streams, springs, and sometimes caves. 

Approximately 20% of the United States is karst.  In karst, the surface and the subsurface are intimately connected; cave and groundwater resources cannot be widely used without careful land use of the surface.  Simply put, clean caves and karst equal clean water.
