The Eastern Bays Songbird Project has been carrying out pest monitoring focusing on hedgehogs, mice, rats, possums and mustelids since 2021. This pest monitoring program runs twice a year at fixed locations, over 11 monitoring lines, using tracking tunnels, chew cards and wax tags.  

Our data shows that we are progressing towards reducing rats over time, but mice, hedgehogs and possums remain at similar rates. Possum relative abundance has stayed low, sitting around 5%, which shows that our efforts are working at keeping possums low, especially as possum reinvasion will always be an issue if surrounding areas don't target possums.
