Waitomo Glowworm Caves, Waitomo, North Island, New Zealand

The walls of the caves are covered with a variety of fungi including the cave flower (a distant relation to the genus Pleurotus) that is actually a mushroom-like fungus. The most common animals in the caves are insects. This includes albino cave ants, giant crickets, and of course the glowworms.
Cave monitoring
The glowworms of the Waitomo Glowworm Caves are closely guarded by a Scientific Advisory Group. This group has automated equipment that continually monitors the air quality especially the carbon dioxide levels, rock and air temperature, and humidity. Data from this equipment is carefully analyzed by specialist staff. The advisory group uses the information to establish how the cave should be managed. They determine if and when air flow patterns should be changed and how many people are allowed to visit the caves each day.
