Control Methods for Rhododendron ponticum.



Hundreds of thousands of euros are spent each year in the effort to eradicate the highly invasive and destructive Rhododendron ponticum in Killarney National Park . It is a native of the Black Sea Region and Iberian peninsula . It was introduced into Ireland in the early 19th century and planted in gardens and woodland as an ornament and game cover. In recent times the Killarney National Park has been examining a variety of new and environmentally friendly control methods for Rhododendron ponticum. Conservation Ranger, Peter O'Toole has had great success with his control methods especially with the stem and plant based treatment using chainsaw. This is proving to be versatile, fast, efficient and cost effective and is being extensively used in the clearance contracts that are underway in the park. Voluntary workers also play an important role in controlling the spread of this invasive species A number of students come to the National Park each year to undertake voluntary work experience and Groundwork, part of the Irish Wildlife Federation run an international workcamp in the park each summer to assist with the clearance programme.
