Nelson’s lizard population is easily missed – these secretive creatures spend much of their time hiding under rocks – but they are a much-valued member of our ecosystems.

The Nelson Green Gecko is of particular importance being endemic to our region. Like birds, lizards are threatened by animal predators and habitat loss. Lizards play a critical role in our ecosystems; they pollinate native plants and disperse native plant seeds through eating fruit.

Predation by introduced mammals (e.g. cats, rats, mustelids) is the biggest threat posed to New Zealand lizards - without predators, their populations flourish. Loss and/or fragmentation of habitat through development, habitat degradation by introduced browsing mammals (e.g. pigs, livestock, deer, goats, possums), removal of logs and rocks, and excessive collecting also contribute to on-going declines of lizards over all parts of New Zealand.

Nelson Green Gecko

The Nelson green gecko is unique to the Nelson Tasman region and is found in open scrubland, such as manuka and kanuka forests. It is hardly ever seen but may be heard as it has an unusually loud barking noise, in fact, the loudest of all the world’s geckos.

Nelson green gecko young are born live and usually as twins, with sticky feet allowing them to move almost anywhere. They are active during the day, seeking insects to feed on. They are threatened by habitat loss and predation by introduced predators, such as rats, mice and stoats.

The Forest Gecko

hite and sometimes orange and yellow. The tongue colour of forest geckos change with changes in pH. Forest geckos have been found associated with exotic forestry in Northland, Auckland, Spooners Range, Nelson and on the West Coast.

Brown Skink

The skinks live in boulder fields and are threatened by predation by introduced mammals like rats, stoats and mice, and also by coastal inundation as a result of climate change. Oligosoma skinks are both diurnal and nocturnal and and occur in diverse habitats from rocky and sandy shorelines, to forests, to subalpine habitats.
