Caves host a unique geo-ecosystem, as a result of their stable environmental conditions, the absence of strong seasonal modifications as well as permanent darkness. A cave's unique and remote environment will host species of fauna and flora not found or able to survive in alternative environments. Thus, a cave's ecosystem is extremely fragile to influence from the outside world. After hundreds and thousands of years of preservation, opening a cave for exploration can significantly impact the ecosystem within.

Since 2020 our team have worked to understand the vulnerabilities of the glowworm's life cycle, being a species largely reliant on precise environmental conditions and susceptible to changes within both their environment and ecosystem.
Our research has focused on safeguarding the species by understanding both natural and anthropogenic threats, as well as finding a solution to alleviate visitation pressure from natural ecosystems.
