Import Restrictions in Response to Green Snail in Victoria

Green snail (Cantareus aperta*) has been detected near Cobram in Victoria. Green snail is a List A pest in Tasmania - that is, we don't have it here and we have import restrictions on a range of plant products to keep it out of Tasmania. Those restrictions are spelt out in Import Requirement (IR) 25 (in the Plant Biosecurity Manual Tasmania).


  Conditions and Restrictions re the Importation to Tasmania of Plants and Plant Products that are host of Green Snail   (139Kb)

The effect of the emergency measures are:
    • All green snail host produce (cut flowers, leafy vegetables, cuttings, nursery stock, hay and straw) from properties where green snail has been detected is prohibited from entering Tasmania.
    • Host produce grown from within a 2 km radius of a green snail infestation may only enter Tasmania if it complies with the provisions of the existing Import Requirement 25 (II) that refers to the protocol for Green Snail requirements to other States as published by Western Australia.
    • Host produce grown from within a 25 km radius of a green snail infestation but more than 2 km from an infested property may only enter Tasmania if it complies with the provisions of the existing Import Requirement 25 (II) that refers to the protocol for Green Snail requirements to other States as published by Western Australia.
    • No green snail trade restrictions on host produce from properties outside of a 25 km radius of a green snail detection.
Note that the emergency measures do not apply to fruit.

Background

Green snail is a pest that can damage a wide range of plants, including cabbages, cauliflowers, lettuces, peas, beans, wheat, lupins, pasture grasses and native plants. Green snails can breed quickly. Prior to the detection in Victoria, Green snail was only found in market gardens, suburban gardens and bush near Perth in Western Australia. The Green snail shell is olive green in colour and is usually a bit smaller than the brown, common garden snail.

*The scientific name for Green snail changed recently. Previously it was Helix aperta.
