Pest Detectives at Sylvia Park School

12 August 2017

We were delighted to recently receive twenty hand-written and beautifully illustrated letters from enthusiastic young pest detectives at Sylvia Park School.

The Year 2 pupils described how they had discovered that there were resident hedgehogs at the school and that hedgehogs are pests.

Interactive species distribution mapping

21 March 2017

Thanks to the Department of Conservation (DOC) for working with us to develop interactive mapping of introduced mammal distributions in New Zealand.

The new tool, which enables viewers to zoom in on particular geographic areas for more detail, so far includes mouse, kiore, ship rat, Norway rat, possum, hedgehog, feral cat, weasel, stoat and ferret. For these species the interactive maps on the DOC website are linked from thumbnail maps in our distribution clue section. For other species not yet converted to the interactive format, we will continue to use static PDF maps.
