How many bettongs?

Admin Aridrecovery - Thursday, June 15, 2017
This May we did a big bettong trap up to estimate the population size for Red Lake and the Main Exclosure. We worked in four teams of 15 people (12 of them volunteers) trapping bettongs flat out for 8 nights straight (with some bonus bilby chasing thrown in for PhD student Aly Ross's project).

Kristi Lee was one of our volunteers and made this video with Katherine Moseby. Have a watch!



We caught 216 bettongs in Red Lake, showing that the population is still increasing despite coexisting with a small number of feral cats. In the Main Exclosure we caught 402 bettongs, a very high success rate: 72% of traps caught a bettong. We also caught 16 Western Barred Bandicoots, 5 Greater Bilbies and one Stick-nest Rat.





Mel Jensen returned to help with the trapping and lead a team. She previously did her Honours on Western Barred Bandicoots at Arid Recovery and was delighted to trap some bonus bandicoots. Photo by Kath Tuft

Volunteer Kim Thomas cuddles a bettong joey that was thrown out of the pouch by its mother. Bettongs are notoriously bad mothers and can eject their young when stressed. We spent some time with this joey and others tucking them back into their mothers' pouches and gently sealing them with light tape. This stops the mother from ejecting the young again when she is released down her burrow, where she'll easily pull the tape off later in the safety of the warren. Photo by Kim Solly


Thanks to all our excellent volunteers for your help!

Thank you for the video, so pleased to see the results of all the years of hard work.
Congratulations on the success of the program.
So sorry I am too old to take part and live a bit far away.
