Tracker Tuesdays - Citizen Scientists Needed!
Cromwell residents are becoming citizen scientists as part of a new community-wide initiative aimed at building a clearer picture of predator activity across Cromwell.
The project, called Tracker Tuesdays, invites people to place simple tracking tunnels and chew cards in their backyards and help collect information about the predators living alongside us. The information gathered helps identify predator hotspots and direct trapping efforts to where they will have the greatest impact.
Predator Free Cromwell volunteer Mary Hinsen says understanding what predators are present, and where, is the first step in reducing their impact on our local wildlife.
"Many people don't realise how much damage introduced predators can do – even here in town. Rats, mice and hedgehogs all prey on native insects, lizards, birds and bird eggs. They also eat fruit and compete with native wildlife for food.
"Our volunteer backyard trappers have noticed rat numbers increasing as the weather gets colder. As summer fruit disappears, rats look for warmer places and new food sources, which often brings them into our homes and gardens."
Participants are using both tracking tunnels and chew cards to detect predators. Tracking tunnels record footprints left by animals as they pass through, while chew cards show distinctive bite marks that help identify species.
Tracking tunnels monitor rats, mice and hedgehogs, while chew cards also reveal the presence of possums.
"Possums remain a significant pest species," says volunteer Shirley Calvert. "They damage trees, eat fruit and put pressure on our local environment. The more information we gather, the better we can target our efforts."
Predator Free Cromwell has tracking tunnels and chew cards available for purchase, but residents are also encouraged to make their own. Simple DIY instructions can be found here.
Participants place tracking tunnels or chew cards in their backyard for up to seven days before photographing the results and posting to Facebook, with the hashtag #trackertuesday, then commenting which street the results come from, and tagging the Predator Free Cromwell facebook page.
Participants not on Facebook can email their photo and street address to predatorfreecromwell@gmail.com
Each Tuesday, Predator Free Cromwell volunteers collate the previous week's results and share a community update on the PFC Facebook page. This means everyone can see just what predators are being detected across the town - and feel great about being an important part of the solution.
Organisers hope the initiative will not only improve predator control efforts but also help people learn more about the wildlife living in their own backyards.
"Every tracking tunnel and every chew card tells us something," says Shirley. "When hundreds of small observations are combined, they create a powerful picture that helps us protect the native species we value."
