Management Information
Integrated management: According to Diedrich and Swearingen (2000), several effective methods of control are available for H. helix, including chemical and non-chemical, depending on the extent of the infestation, the amount of native vegetation on-site, and available time and labor. Vines growing as groundcover can be pulled up by hand, with some difficulty, and left on-site or bagged and disposed of as trash. Vines climbing up into the tree canopy are more difficult to manage. First, vines should be cut at a comfortable height to kill upper portions and relieve the tree canopy. Because H. helix is an evergreen vine and remains active during the winter, herbicide applications can be made to it any time of year as long as temperatures are above12 or 15 degrees Celsius for a few days. The systemic herbicide triclopyr (e.g., Garlon) is absorbed into plant tissues and carried to the roots, effectively killing the entire plant in place. Repeat herbicidal treatments are likely to be needed and follow-up monitoring should be conducted to evaluate the success of treatments.
Location Specific Management InformationGarry Oak Ecosystems (Canada) (Canada)
The ISSC (Invasive Species Steering Committee) of the Garry Oak Ecosystems Recovery Team (GOERT) (a partnership of a number of governmental and non-governmental agencies) which focuses on research and management of invasive species in Garry oak and associated ecosystems has developed a Decision Support Tool for Invasive Species management and Field Manual for invasive species. The field manual for Hedera helix can be seen here . Rangitoto Is. (New Zealand)
In 1995, a weed control programme was initiated on Rangitoto Island, with 72 weed species identified. These were split into three priority classes, each with a management objective. The long term aim for this species is control to zero density (no adult plants).
