We identified 19 tracking locations (S1-S19) in 2014. The first 10 (S1-S10) were used in this survey. The survey was repeated in March 2019. The first 10 locations were searched and three out of 10 tracking tunnels were found. Seven new tracking tunnels were installed on the 10th of March. On the 16th of March […]

Altho I have been to most of Revive our Gulf’s deployments (including the first one in 2013) we have’t dived on them straight away. After taking this photo I deployed three time-lapse cameras to record suspected predation (I was happy to […]

Black nightshade is dominant and there are thousands of woolly nightshades coming up, some as large as 1 meter wide already. Inkweed, apple of sodom and […]
New Zealand has two praying mantises, the invasive South African praying mantis and the native New Zealand praying mantis. The easiest way to tell the two species apart is the shape of the head. The thorax (bit that connects their heads to their abdomens) is much wider on a New Zealand mantis so by comparison […]
I have started work helping New Zealanders keep their Parks and Reserves. Building and Construction Minister Dr Nick Smith says that we have to “choose between using land for houses or cows”. This is ridiculous – saying our reserves are for cows is like saying Eden park is for lawn mowers!
