Barking up the wrong tree?

3 November 2020

Bark damage is often a clearly visible animal pest sign but identifying the culprit is not always easy – as Roger Young found at his property on the outskirts of Christchurch.

After returning from holiday earlier this year, Roger was dismayed to see a lot of damage on some lowland ribbonwood (Plagianthus regius) trees in his restored wetland. He at first suspected possums because they had repeatedly stripped bark from gum trees elsewhere on his property and he had trapped a good many in that area. Normally, he would have been checking his property daily and would have noticed the damage before it became so extensive.

New Zealand Nature Heroes

A new book is set to inspire and empower New Zealand kids to be naturalists and conservationists – including being pest detectives.

Author Gillian Chandler wrote New Zealand Nature Heroes to encourage children to become citizen scientists, actively engaged with their local environment.

The book emphasises the importance of observation in nature conservation and suggests varied activities that children can undertake for themselves.

Detecting pest animals is one such activity. There are simple instructions on how to make tracking tunnels and chew cards, with a link to our Pest Detective website for help on identifying the animal signs observed.
