This chapter reviews the development of agriculture in New Zealand and the emergence of introduced herbivorous gastropods as pastoral pests. In the context of an agroclimatic classiication, the link is made between environment, land use, and ecology of the gastropod communities. The pest status of Agriolimacidae, Arionidae and Milacidae is then addressed in the context of (i) established pastures, (ii) pasture establishment, (iii) forage-seed crops, and (iv) transmission of plant pathogens.
