A blue-tongue stretched out beside a garden bed can look out of place if you were not expecting company. Usually, though, the garden is part of its home. Moving a healthy lizard to a distant patch of bush is not an improvement it has asked for.

Spring is a good time to notice these neighbours. Give them room, keep pets away and watch without picking them up. The most useful changes are often to the garden and our routines.

A familiar patch matters

Blue-tongues use a home range where they find food and shelter. South Australia’s environment department advises avoiding relocation: unfamiliar surroundings can leave a lizard without the resources it knows. Instead, remove a threat such as an interested pet and allow the lizard to move away by itself.

This is a useful way to think about a garden encounter. The animal’s presence alone is not a problem to solve. If a dog is investigating it, secure the dog rather than carrying the lizard elsewhere. Give it an unobstructed opportunity to retreat, without crowding it for a photograph.

If you think it is in immediate danger, ask a licensed wildlife rescuer for advice. Do not attempt to catch, box or relocate it unless a rescuer or vet specifically directs you.

Meet the eastern blue-tongue

The Australian Museum describes the eastern blue-tongue as a large skink found in open country with ground cover, including gardens. It occurs around Sydney’s coastal plain and lower Blue Mountains. Other blue-tongue species live elsewhere in Australia, so this is not a description of every local lizard.

Eastern blue-tongues shelter under logs, rocks or similar cover at night and warm themselves in the morning sun. Their food includes plant material and slow-moving animals such as snails and beetles. A flash of blue tongue is a defensive display, not an invitation to interact.

The museum places their mating season in September to November. Seeing an active lizard at this time of year can be ordinary seasonal behaviour. There is no need to turn that sighting into a rescue simply because the animal is conspicuous.

Leave useful places to hide

NSW’s advice for garden reptiles starts with habitat: native grasses, ground covers, leaf litter, mulch, rocks and logs offer places to shelter. Keep useful cover that is already in your garden. Do not collect bush rock from natural areas to make a new feature.

You can plan a garden around these small spaces. A sheltered bed beside an open basking spot gives a reptile more choices than a completely cleared surface. Resist tidying every corner down to bare ground, and keep pets from investigating the places where animals retreat.

NSW also recommends reducing chemical use in a reptile-friendly garden. Insects are part of the food supply for many reptiles; protecting that habitat means thinking beyond the lizard you can see.

Check before garden work

Blue-tongues can be injured by mowers and whipper snippers. The Australian Museum notes that they may hide in long grass rather than flee machinery. Look over the area before starting and postpone work around a lizard until it has moved on by itself.

Avoid snail pellets and other garden poisons that can harm lizards directly or through their food. Feeding a wild blue-tongue is unnecessary; a garden with natural food and shelter is the better starting point.

An obviously injured or unwell animal needs professional advice. Our injured-wildlife page explains the first steps, and the rescue directory can help you find a licensed group or vet. Watch from a distance while arranging help.

The bottom line

A healthy blue-tongue is usually best left in its familiar surroundings. Protect its hiding places, control pets and check before mowing. Change the hazard where you can, and let the lizard get on with being a lizard.
