Pest detectives have discovered that a weasel has managed to find its way past the pest-fence and into the wetland reserve at Rotopiko near Ohaupo.
The National Wetland Trust, a community operated project, built the pest-fence in 2012 and since then, and up until last week, the only mammal pests
that have managed to get through have been the occasional mouse.
Staff and volunteers of the trust regularly check a network of tracking tunnels to monitor numbers of native critters like weta and skinks but also to keep a close eye on any potential fence busters such as the weasel.
Trust executive officer Karen Denyer discovered that there had been an intruder when she pulled an inked footprint tracker card from a tunnel, when she saw what was on it she said her heart sank.
"We'd just had a fantastic day planting and learning about wetlands with Year 3 and 4 students from Ohaupo Primary School. They learned to read tracking cards, and I was telling them we've never had anything but mice get inside the fence.
