An unexpected discovery of four different turtle species in Dumaresq Dam, located near Armidale in northern New South Wales, has raised alarm among researchers about the potential risk to endangered native turtles. The investigation, led by a team from the University of New England, was prompted by posts on social media noting sightings of endangered Bell's turtles in the region. This is particularly concerning since native turtles typically inhabit flowing water environments, making their presence in a still dam uncommon.

During a survey conducted from January 19-22, researchers recorded several species, including the endangered Bell's turtles, the eastern long-necked turtle, Murray River turtles, and one broad-shelled turtle. The possibility that some of these turtles may be dumped pets has led to fears that they could disrupt the local ecosystem and compete with or pose diseases to the native turtle populations. The current situation highlights the critical need for genetic testing to ascertain the origins of these turtles, which will help in understanding whether they have arrived at the dam through natural means or as a result of pet abandonment.

This discovery raises important questions regarding wildlife management and conservation efforts in New South Wales. If confirmed that pet turtles were indeed dumped, it sheds light on a growing issue of pet abandonment in the region and its potential ecological impacts. Researchers emphasize the need for public awareness and education on the responsibilities of pet ownership, particularly regarding non-native species that can significantly affect the local habitat.
