1080 and Possums in New Zealand
What is 1080? (sodium fluoroacetate)
1080 is a pesticide used by the department of conservation to protect New Zealand native species from pests (e.g possums).
Pesticide is poison used to kill pests
Possums fall into the category of introduced pests in NZ. They are the main threat to native plants and animals in NZ.
Estimated 30 Million possums in New Zealand
Kill birds and chicks. Raid nests for eggs.
Carriers of lethal disease - bovine tuberculosis
Pass on infection to cattle
Dairy + Meat is a $14 Billion dollar industry in New Zealand. Major export.
Along with stoats - responsible for 70% of infection in cattle herds
Tuberculosis infected possums are in 40% of NZ.
Studies prove the effectiveness of 1080 against possums
1080 dispersion in NZ
Primarily Aerial. Poisoned foodstuffs dropped from Helicopters into forests.
Most effective way to cover large area
Consumed by possums and rats killing them. Also kills stoats that feed off of possum and rat carcasses.
e.g Cereal Pellets + Poison laced carrots
1080 and the Environment
Does not bio-accumulate - not harmful to the environment in and of itself
Doesn't leave residue in soil, plants or water
Does not pose significant threat to any
New Zealand ground dwelling mammals
20,000 deer poisoned annually from 1080
Highly Water soluble
1080 residues have never been recorded in public water supplies
Dead rodents/pests can pollute waterways with their dead poisoned carcasses
