Predator control programmes
Introduced mammalian predators pose a serious threat to all New Zealand birds including penguins.
The Trust maintains trap lines at all our reserves, which are cleared weekly during the penguin breeding season and less frequently (2-3 weeks) over the rest of the year.
The most widely used traps on our reserves are DOC 200s and DOC 250s, targeting rats and mustelids, with smaller numbers of Mk6 fenns, which are gradually being phased out as they rust and reach the end of their operational lives.
Cats are trapped with Timms traps and Steve Allan cat traps.
The traps are always set in tunnels to prevent access by non-target species, or in the case of the cat traps are placed outside the penguin breeding areas.
