Why is it invasive?
Clare Island Project
Last updated: 17th November 2009
Gunnera tinctoria is an invasive species in Mayo and in 2006 Mayo County Council
started a project to tackled the problem at hand. The project got funding from the
Heritage Council's Biodiversity Grant, Mayo County Council and NPWS. It started as
Masters project carried out at University College Dublin, looking at the use of
herbicides to control this plant. The experiments ran over 2-3 years.
the Heritage Council's Biodiversity Grant and Mayo County Council continued to
fund the project, to both continue the experiments and to map the distribution
on Achill Island, one of the worse affected areas in the County. With the
information gathered from these projects an information leaflet and management
plan were produced. In 2008-2009 Mayo County Council in conjunction with the
National Botanic Gardens and continued funding from the Heritage Council
started a control pro gramme on Clare Island, a special area of conservation
with good possibilities of eradicating this plant.
