Études de cas sur la gestion Auckland Region (North Island) H. verticillata has been designated as a Surveillance Pest by the Auckland Regional Pest Management Pest Management Strategy 2002-2007. Please see Hierarchy of Plant Designations for an explanation of designation terminology. Australia A biological control programme for Hydrilla verticillata was undertaken simultaneously with programmes for the other aquatic invaders Eichhornia crassipes, Pistia stratiodes and Salvinia molesta, to avoid the increase of other invasive species as one was controlled. Southern Florida Hydrilla verticillata has been controlled in canals with a combination of herbicides and grass carp (Ctenopharyngodon idella). However, its decline has coincided with the increase of the equally invasive Hygrophila polysperma.          Ressources pour la gestion/Liens 1. CAIP (Center for Aquatic and Invasive Plants), 2001.

Importers and traders in aquatic plants were surveyed to identify the plant species known or likely to be present in New Zealand. The Aquatic Plant Weed Risk Assessment Model was used to help assess the level of risk posed by these species. The report presents evidence of the various entry pathways and considers the impact that new invasive aquatic weed species may have on vulnerable native aquatic species and communities.
