We have now conducted a test deployment of our new ultrasonic acoustic monitors and had a meeting with Federation University to discuss what additional data we will be collecting.
Along with ultrasonic audio recordings to record our local bats we will be collecting habitat data such as presence of hollow bearing trees, canopy health, canopy cover, presence of fruit bearing trees and other information. This data will help us determine what bat species require certain conditions. As we continue this program annually we will build up an incredible data set that Federation University students will be able to use and draw insights from.
So what does ultrasonic sound like? Well, you can listen here. Chances are you won't hear much though as ultrasonic means noises that have a frequency over 20,000Hz. The human ear can hear between 20Hz - 20,000Hz, so most bat communication that occurs is out of range to us. Which is why we need special microphones to record them.
Production of bat boxes are also underway curtesy of the Ballan Men's Shed. Bat boxes create instant habitat for bats, who generally rely on trees hollows to nest in. Tree hollows take 80 years to form naturally, so creating habitat in the short-term is a very important step in bat conservation. Bat boxes will be available to members in Spring.
Landholders who put their hand up to participate in the first round of monitoring project will be contacted soon to discuss survey dates. We are aiming to begin monitoring in September once the weather warms and creates more bat (and human) activity.
EDIT: No bats are handled during this monitoring project.
-Only vaccinated and trained wildlife officers or vets should handle live bats.
-Handlers use thick puncture-resistant gloves, leather gauntlets, eye protection, and specialized towels.
-Report sick or distressed bats with suspected disease to Agriculture Victoria or the Emergency Animal Disease Hotline.
