Feral goats moved on from Adelaide park

A herd of feral goats that has wreaked environmental havoc at an Adelaide conservation park for several years has finally been removed.

The SA government says rangers have been trying to usher the pesky goats out of the Morialta Conservation Park using various methods since 2015.

The 60 goats have been driving away some native species by trampling and eating native vegetation and leaving bad smells at their camps.

The southern brown bandicoot and the chestnut-rumped heathwren are among endangered animals in the park to have been bothered by the herd.

Environment Minister Ian Hunter said the removal of the goats will allow native plant growth to flourish but authorities can't afford to let their guard down.

"Constant vigilance will be required into the future, as goats don't recognise land tenure or park boundaries, and others could move back into the park," he said.

Rangers have been monitoring the goats to find the best spots to catch them by fitting one with a tracker collar, setting up motion-sensing cameras in the park and noting sightings by park visitors.

Fencing off one of the goat's favourite waterholes allowed many of them to be trapped over time and removed from the park by truck.

Although the park has been declared goat free, the state government said one may remain as a "Judas goat", which is trained to herd other animals.
