Waitomo's Environmental Officer: Meet Carl


Due to the many Waitomo adventures in the area, the Environmental Officer has an extremely important role in Waitomo and sustaining this special part of New Zealand is his top concern. When he can, Carl likes to spend time out of his office, going about his day-to-day activities. This includes environmental monitoring, this is monitoring of the cave micro climate including Co2 levels in the Glowworm Cave, Ruakuri Cave and Aranui Cave. When the caves become very populated in peak season, Co2, which is exhaled by people and concentrates in places with limited ventilation like a cave, levels can potentially reverse the process of deposition that creates cave formations (stalactites and stalagmites) and begin to instead corrode them. This can even mean closing the caves for an hour or so to lower the high levels of Co2 within the glowworm cave. This ensures that our caves are sustainable for the beautiful glowworms and spectacular cave formations.
