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
- Grassland or savanna
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 Zones in which the Spencer's Monitor has been placed has been chosen based upon an assessment of its typical basking behaviour and likely microhabitat in the wild.
Recommended lighting methods in captivity
Sunbeam method
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 Spencer's Monitor can obtain at its closest approach to its UVB lamp. The highlighted area in the table below represents this range for the Spencer's Monitor.
