The exclusion programme aims to stop certain pests that are in very low numbers or in surrounding areas from establishing in Otago.
Below is an example of the pest infestation curve which is used around New Zealand to help us figure out the best management option for pests. Where a pest sits on the curve tells us the most cost-effective way to control or eradicate it.
African feather grass
A tussocky grass that forms thick clumps up to 2m high. Report this pest!
Chilean needle grass
Chilean needle grass is a tough, tufted grass that grows up to 1 m tall. It forms dense patches and spreads sharp, barbed seeds that stick to animals, clothing, and vehicles. The seeds can cause painful injuries and even blindness in livestock. Report this pest!
Egeria
Egeria is a fast-growing freshwater weed that forms dense underwater meadows, blocks waterways, and harms aquatic life.
False tamarisk
False tamarisk is a shrub up to 1.5 m tall with upright branches and small, bluish-green, narrowly triangular leaves. In summer (January–March), it produces small pink flowers in hanging clusters, followed by grey seed capsules. Report this pest!
Hornwort
Hornwort is an invasive underwater weed that forms thick mats, and blocks waterways. New plants grow from broken stem fragments spread by boats, trailers, and gear.
Moth plant
Moth plant is a fast-growing climbing vine that can reach over 5 m tall. It smothers shrubs, small trees, and native seedlings, harming biodiversity. Crush its stems or fruits and it oozes a caustic milky sap that can irritate skin and is poisonous to people. Report this pest!
