- Range
- Central Otago. Restricted to specific dry rocky slopes and schist outcrops in inland South Island locations.
- Endemism
- Endemic
- Main Threats
- Habitat loss from agriculture and urban development. Climate change affecting temperature regimes. Predation by introduced mammals.
- Population
- Nationally Vulnerable. Restricted to specific Central Otago locations. Population declining due to habitat loss and climate change.
- Conservation Status
- Nationally Vulnerable
Skin is rough. Not smooth like forest relatives. But granular, adapted to dry schist environments. The Cromwell gecko grows on dry rocky slopes where heat radiates from stone surfaces. Its colouration is pale grey, blending perfectly with weathered rock. This cryptic appearance helps it avoid detection by predators.
Woodworthia "Cromwell" inhabits dry rocky slopes and schist outcrops in Central Otago. It prefers exposed sites with high temperatures, thriving where other reptiles cannot survive. Unlike moist-forest geckos, it has specialised scales that reduce water loss. Adults reach up to 9 centimetres in length, with a slender build adapted to narrow crevices. Their large toes provide grip on smooth rock surfaces.
Diet consists primarily of small insects and spiders. The gecko hunts at dusk when temperatures are cooler. It also consumes nectar from native flowers when available. This omnivorous diet allows it to survive in arid environments, though it requires reliable insect populations to thrive.
Breeding occurs in spring and summer, with females giving birth to one or two live young. Young are fully formed and independent at birth, fending for themselves from day one. This strategy maximises survival chances in a harsh environment.
Classified as Nationally Vulnerable, the Cromwell gecko faces an uncertain future. Habitat loss from agriculture and urban development remains the primary threat. Climate change may alter temperature regimes affecting survival. Each surviving juvenile represents a victory against overwhelming odds. The Cromwell gecko persists where protection is maintained. A testament to resilience in a changing landscape.
