Released snakes survive first months in the wild
At least three of six captive-born broad-headed snakes have been found after their release in Australia.
At least three of the six endangered broad-headed snakes released in Australia in May appear to have survived their first months in the wild. Researchers call the results encouraging, but stress that a sustainable population is far from certain.
The snakes were released near Nowra in New South Wales. They were young animals born in captivity to wild-caught parents. The programme is a collaboration between conservation organisation Aussie Ark, the University of Technology Sydney and traditional landowners from the Shoalhaven region.
Researchers check the area roughly every two weeks. During recent checks, at least three of the six released animals were found again. According to the project team, one snake showed signs that it had fed in the wild. It has not been established whether the three animals not seen have died or are outside the area being surveyed.
The broad-headed snake lives only in and around the sandstone region of the Sydney Basin. The species is threatened by habitat loss and fragmentation, the removal of rocks and the disappearance of hiding places. The animals grow slowly and reproduce relatively infrequently, meaning population recovery takes time.
The project began in 2024 with the collection of adult animals for a breeding programme. According to Aussie Ark, eight young were subsequently born. Six of them have been released, while two are being kept temporarily in the breeding population because of their genetic value.
The first months after a release are important, but do not prove that the species is already recovering. The animals must survive for several years, reach maturity and reproduce. It must also become clear whether the habitat is large and safe enough to support a self-sustaining population.
Even so, the project shows how targeted protection, breeding and monitoring can complement one another. The results are particularly relevant because an earlier attempt involving another snake species failed because of predation. For the broad-headed snake, protecting natural rocky and forest habitat remains at least as important as breeding itself.

Editor's note
At least three animals have been found; there is no certainty about the other three. The outcome is an early monitoring indicator, not evidence of population recovery.Sources
