From shimmering rock pools to stunning chambers, The Tākaka Hill Biodiversity Group Trust has successfully completed their Cave Fauna Survey for 2025.

Earlier this month, a dedicated team conducted comprehensive fauna sampling from 13 caves in the Tākaka Hill region and the surrounding Takaka area

“The caving team navigated challenging conditions, including narrow passages and flowing underground streams, to collect samples for identification and DNA analysis”, a spokesperson from the trust says. “Their dedication to exploring and understanding these critically endangered ecosystems is vital for preserving our natural heritage.”

The trust also recognised the efforts made by members of the Nelson Speleological Group (NSG), including the retrieval of an isopod from a cave sink.“This unique organism exemplifies adaptions necessary for survival in cave habitats and is just one of the many significant findings from our survey,” the spokesperson adds. “The NSG’s ongoing efforts to remove mud and sediment from caves help mitigate a significant threat to cave biodiversity caused by visitor activities.”

They also thanked Taylors Contracting for generously providing a 4WD vehicle to access the caves. “Additionally, we appreciate the financial support from Hapai Hapori Community Matters Lotteries Environment and Heritage, which helped cover the costs associated with this vital monitoring project.” The team will be sharing further updates soon as they begin to analyse their findings from the survey. “The trust remains committed to restoring and safeguarding the exceptional cave ecosystems of the Tākaka area.” Videos showcasing the team and various cave fauna species observed during the survey are available on the Tākaka Hill Biodiversity Group Trust Facebook page.
