Going boating or kayaking in the Abel Tasman?

Help keep Adele/Motuareronui, Fisherman/Motuarero-iti and Tonga islands predator free to help our wildlife.

In 2017 a mouse eradication was completed on the Abel Tasman islands.  While the islands can't be declared officially predator-free for two years after the eradication, so far monitoring is showing it was successful.

The islands first became predator-free wildlife sanctuaries in 2007 but mice were found back on the islands in 2015 when pest numbers were high in the Park due to a heavy beech mast.  During a beech mast there is abundant food which fuels breeding. 

Rats are a threat to South Island robins/toutouwai and saddlebacks/tīeke that have been returned to Adele Island and to robins that have spread to Fisherman Island. Rats and mice threaten insects and lizards and, as they also eat seeds, they suppress re-vegetation. Mice can even eat small birds’ eggs and nestlings.

Rats and mice can stow away on visiting vessels and escape onto islands so it is important that people check their boats, kayaks and gear for pests before they head into the Park. Even if you don't land on the islands, rats and mice can swim if you moor nearby.  Some predators can even swim from the mainland.

The islands do have measures in place to counter invading predators, including traps to catch them and tracking tunnels that record footprints to detect them but we need your help to keep them predator free.

If landing at Adele or Fisherman Island or mooring near any of the islands, please check boats and gear are free of rats, mice, ants, seeds and weeds.

Help keep these islands safe for native wildlife. For more information please visit www.janszoon.org/biosecurity
