Conservation and collecting New Zealand insects
Nearly all New Zealand aquatic and terrestrial invertebrates (approximately 95% of the total fauna) are strictly confined to native vegetation habitats and have little chance of survival outside of these. The ever increasing loss of habitats resulting from forestry, agriculture and industrial, urban and recreational development is leading to a situation where the survival of a number of species may be endangered. Conservation of certain insects and other invertebrates is therefore becoming increasingly important. Although the reduction of native vegetation habitats poses the greatest single threat to the survival of the New Zealand native invertebrate fauna, other factors are also important. Fire eliminates many species, especially terrestrial Mollusca,even though the vegetation may recover. Introduced animals may compete with or eliminate native species. Rodents brought to this country are thought to have eliminated a number of species from the mainland. The activities of human collectors should not go unnoticed either.
