Cave Restoration Benefits to Cave Formations

CAVING SERIES 4
By Bryan Kleist, Wisconsin Speleological Society
In the past articles we have explained how restoration of the caves is beneficial to humans as well as the cave creatures who inhabit them. Restoration is also very important for the cave formations!
Since cave formations are limited to forming only in the voided spaces, here in this part of Wisconsin the formations found are usually small. Voids of six inches or less are typical so the formations remain small. Once the cave is re-established by removing the glacially deposited sediment, the formations can grow much larger. These stalactite and other formations are also protected that much more because they are then higher up out of harm’s way due to the substantial increase of space below them.
The Wisconsin Speleological Society has learned, prior to full restoration that the caves are usually dry, and their temperatures fluctuate. Humidity levels are also less than favorable for optimal cave conditions. Once the caves are restored, humidity levels increase and the formations once again have water running over them most of the time. The end result is improved growing conditions are once again created, and these now “living” cave formations can once again continue growing!
We have also adjusted, or controlled air flow movement thru caves to create optimal cave conditions for formations as well as for the cave critters. By placing solid doors at the entrances (with adjustable air venting) the air flow is minimized. The once dry caves with fluctuating temperatures now become more environmentally stable. Consistent temperatures, high humidity levels, and minimal air flow allows formations to grow and promotes the best home conditions for the cave critters.
