Imagine living in a garden full of dragons. Imagine have breakfast while chatting to one, or walking down the main street and seeing one casually draping itself over a sign in front of the police station.
I’m speaking of course of the Eastern Water Dragon (Physignathus lesueurii).
Growing up to a metre in length they are the largest dragons in Australia but are sometimes mixed up with their cousins, the Gippsland Water Dragon. You can tell them apart if you look at their faces: the Gippsland ones don’t have a black stripe going from their nose to their ear.
Water dragons are, as their name suggests, very well adapted to water. Their tails constitute 2/3 of their body length and are used for swimming while their nostrils are on the top of their heads making it possible to breathe while their heads are submerged, a trait they share with crocodiles. Like other lizards such as lace monitors and goannas they can use their strong claws to climb quickly and easily.
They are good indicators of biodiversity as they mainly prey on insects and frogs as juveniles, meaning that if there is a healthy population of dragons there is also a healthy population of insects and frogs. When they’re older they become omnivores. It’s always nice to see predators like dragons and kookaburras in the garden as it means that the garden ecosystem is diverse and healthy enough to support them.
It is possible to identify males and females as males have crimson, vermilion or orange chests to attract mates. After mating a female will lay a clutch of eggs in soft soil or sand by the water and when the baby dragons hatch they are completely self sufficient. However, studies have shown that the temperature of the eggs during incubation can determine the sex of the dragons. This is worrying as males are only produced in middling temperatures, with females produced in cooler and warmer temperatures, so over time the species may becomes less viable as there are fewer males produced due to the temperature of the ground being affected by increasing temperatures.
Although it’s legal to keep water dragons as pets in NSW you need a license for it and it is ideal that you only purchase reptiles from other license holders to try and source reptiles that are healthy and well looked after. It is illegal in Australia to keep animals that have been collected from the wild. Keeping these beautiful lizards as pets seems strange to me, why not just make your garden suitable for them?
Do that and they’ll come of their own accord. Build a pond or a small waterway, have lots of native shrubs to hid in. Make sure that your garden has plenty of flowers to attract insects and have a pile of old logs and tiles for reptiles to hide in and sunbake on. Also, keep your cat indoors. Or just don’t have a cat. (We were talking about this last night at dinner and I said “At least with dogs you can fence them in; there isn’t much you can do with cats.” Without missing a beat Dad said “You can do two things with cats: drown them or shoot them.”) Dragons aren’t meant to be kept in small glass boxes; they’re wild animals, not puppies to be played with.
If you have lizards in your yard resist the urge to feed them – it’s not healthy for them and teaches them to rely on you. Instead, just sit quietly and watch them. We should encourage and appreciate urban biodiversity, not seek to control it or interfere with it.
