Management Information The Victoria DNR (2001) states that the best plan of attack is to begin remove small and scattered plants first and then target outer edges of larger infestations. It is best to best to remove plants before they seed. Small Plants can be hand pulled or dug out. One should carefully remove all roots, and minimize soil disturbance. Young seedlings can be sprayed with a suitable herbicide if appropriate. For larger infestations, the authors suggest cutting climbing stems from roots with secateurs. Then proceed to dig out root stumps. Alternatively, one can paint cut stumps of large plants with suitable herbicide immediately after cutting. Hand pull or dig out trailing vines, carefully removing all roots and minimizing soil disturbance. Sites need to be monitored regularly for regrowth and new seedlings, which can be easily hand pulled or dug out. Seed stored in soil is substantially reduced by fire. Mature plants are fire sensitive. The Eurobodalla Shire Council (2004) states that, "A hot fire could be used to kill mature plants and stimulate the germination of seedlings, which can then be sprayed or pulled."              Location Specific Management Information Auckland Region (North Island) D. lignosus has been designated as a Surveillance and Community Initiative Pest by the Auckland Regional Pest Management Pest Management Strategy 2002-2007. Please see Hierarchy of Plant Designations for an explanation of designation terminology. Canterbury Region (South Island) D. lignosus is designated as an "Unwanted Organism" by Environment Canterbury. Please see the Pest management strategy Part II 3.1 for defintions of classification of pests. New Zealand D. lignosus is included in the First Schedule of the National Pest Plant Accord. All plants on the list are designated as Unwanted Organisms, and are banned from sale, propagation and distribution throughout New Zealand. Please see National Pest Plant Accord for the complete list. Waikato Region (North Island) D. lignosus is classified as a “Nuisance Plant Pest” by Environment Waikato, which means it has been established for a considerable time and is probably widespread. While Region-wide control would be impractical and costly, there is benefit to those who wish to control specific infestations. Please see definitions for hierarchy of pest designations.          Management Resources/Links 1. Eurobodalla Shire Council. 2004.
