November 2018 – Rats and rare birds

Controlling rats is the key to creating a healthy forest. Rats eat almost everything. They eat the fruits and the seeds that fall on the forest floor so there are few seedlings to replenish the forest or for the native insects in the leaf litter to eat. Rats eat the native invertebrates – like beetles, weta, grubs and worms – which are also food for birds like robins. Rats eat birds’ eggs and chicks in the nest. This is devastating for kereru which only lay one egg in a nest. So it is no ...

It was a brown and grey forest gecko, an endemic species, which means it is native only to NZ. Then two years ago on a guided walk led by the Aongatete Trust an observant participant saw a green gecko, just as another walker trod on i...

December 2016 – Spiders

If you go into the forest at night and shine a torch around the tree trunks, you will see tiny pinpricks of light. It is the reflection of spider eyes. These spiders are not the ones that live in our houses – they are nearly all newcomers, accidentally introduced from other countries. The spiders in the forest all belong there, some of the 2500 odd species native to New Zealand. At night, spiders are out hunting. In the trees the orbweb spiders sit in the centre of their symmetrical web. O...
