Would you believe me if I told you this little bat can live up to 22 years old!?
Weighing less than a double-A battery, the Southern Bent-wing Bat (Miniopterus orianae bassanii) is a critically endangered insectivorous bat found in SA and VIC.
Impacted by land clearing of foraging habitat, human disturbance to roosting caves, feral animal predation (cats & foxes) and wind turbines, the Southern Bent-wing Bat’s population has decreased by an estimated 67% since the mid-1990s. It was first listed as ‘critically endangered’ in 2007, and has remained so in its recent 2021 review.
So how can *you* back this bat?
1. As always, public awareness is key! Share posts and talk about the Southern bent-wing bat, and ways to conserve it.
• Due to its dependence on limited limestone caves, this bat is highly susceptible to human disturbance. Sadly, deliberate vandalism of roosts is a current and known threat (one example being from Warrnambool VIC, where the surrounding vegetation of a maternity site was set alight, and large logs were thrown into the cave entrances). Improving public awareness of these bats and their importance, helps protect these caves and may minimise vandalism.
1. If you live along the south coast- plant locally-native plants to boost your local population of native invertebrates; bat food!
• Aim to plant a diversity of locally native species, of different growth forms if possible- I.e. native grasses, ground cover species, forbs, shrubs, and trees.
• If you aren’t able to do this on your own property, consider volunteer with your local landcare group, school or similar organisations working to revegetate the coastline.
