The threat of predators was identified at the beginning of the 1900s and through the efforts of scientists and experts from the Department of Conservation (DOC), TBFree (OSPRI) and regional councils, it has become increasingly better understood.
Throughout the 20th century, government agencies – mainly DOC, TBFree, regional councils and Landcare Research – invested many hundreds of millions of dollars in battling mammalian predators. Their expertise is now internationally recognised.
At the same time many thousands of New Zealanders, generally as volunteers, individually or in groups, have invested millions of hours killing rats, stoats and possums all over the country. While there have been many success stories, sadly overall the battle is being lost; predator populations are increasing and many native species are in decline.
