South East Asian box turtle

Alert

Have you seen South East Asian box turtle?

Be on the lookout for South East Asian box turtle and report it to Biosecurity Queensland. Early detection and reporting are the key elements in preventing South East Asian box turtles from becoming a major problem in Queensland.

Native to South East Asia, the South East Asian box turtle is a brown turtle with a domed upper shell and hinged lower shell. Its natural range extends from mainland Indochina, Malaysia and Borneo to Thailand and Singapore.

Although it is classed as vulnerable by the International Union for Conservation of Nature (due to its exploitation for the international food, pet and medicines trade), the South East Asian box turtle is still relatively common in most of its range. This may be because it can live in many natural and artificial habitats, including rice fields and near human settlements.

The South East Asian box turtle has not established in Australia but, if introduced, would compete with native turtles for food and space. To prevent South East Asian box turtles establishing in Queensland, restrictions apply to their import, possession and sale.

You must not keep, feed, move, give away, sell or release into the environment. Penalties may apply.

You must report all sightings to Biosecurity Queensland within 24 hours.

Habitat

  • Adapts to and occupies wide variety of natural and artificial wetlands in tropical rainforest areas.
  • Habitats include marshes, creeks, swamps, ponds, permanent or temporary wetlands, shallow lakes, flooded rice fields, irrigation ditches, canals, ponds, pools near houses or nearby to these areas.
  • Juveniles are mostly aquatic.
  • Adults are semi-aquatic and spend more time on land.
  • Can move rapidly on land, and be found quite far from water.

Distribution

Life cycle

  • Average life span 25–30 years.
