Microhabitats

Microhabitats are specific small habitats that an organism inhabits within its broader environment. These can vary greatly depending on the species and can give us insights into the preferred living conditions of each reptile. Understanding these microhabitats can be key to providing the correct care for these animals in captivity.

  • Rocks, crevices or burrows

Ferguson Zones

Ferguson Zones are a way to classify the amount of UV light that reptiles are exposed to in their natural habitats. These zones help us understand and replicate their natural light conditions in captivity, promoting the health and wellbeing of the reptiles. Below, we detail the specific Ferguson Zones of the Chinese Water Dragon, along with recommendations for replicating these conditions

The Ferguson Zone in which the Rio Fuerte Beaded Lizard has been placed has been chosen based upon an assessment of its typical basking behaviour and likely microhabitat in the wild.

Partial sun or occasional basker
UVI range avarage: 0.7-1, UVI max recorded: 1.1-3

Recommended lighting methods in captivity

Shade method

This method provides low-level 'background' UV at levels matching the Ferguson Zone Range, over a large portion of the enclosure. The highlighted area in the table below represents this range for the Rio Fuerte Beaded Lizard.

Sunbeam method (only for large enclosures)

This method uses the 'Max UVI Recorded' value as a guide for the upper limit of the UVB gradient in captivity. This maximum should be the highest level which a Rio Fuerte Beaded Lizard can obtain at its closest approach to its UVB lamp. The highlighted area in the table below represents this range for the Rio Fuerte Beaded Lizard.
