Japanese Knotweed is a “vast problem” in Carrick-on-Suir, Cllr Kieran Bourke told the municipal district meeting
TipperaryLive.ie reported in June that there are between three and four acres of the invasive Japanese Knotweed growing on public and privately owned land in Carrick-on-Suir.
A contractor working on behalf of the local authority over the last four years has eradicated 20 of 37 sites listed for treatment due to the pest plant on national routes around the county.
The remaining 17 sites where the plant was not fully eradicated will undergo a further one-year treatment process.
Transport Infrastructure Ireland allocated funding of €11,000 to the council in April of this year for the completion of the 2020 Invasive Alien Plant Species plan. Of the remaining 17 sites on national routes around Tipperary which were not fully eradicated by treatment since 2016 and up to December of last year, there was a re-growth of 5% or less recorded.
Tipperary County Council plan to spend €12,000 in the Carrick-on-Suir Municipal District this year - a sum which has also been allocated to the other Municipal Districts and the Clonmel Borough District - to eradicate this non-native plant that is now regarded as a pest species in Ireland as it is so invasive.
At the recent Carrick-on-Suir Municipal District meeting, Cllr Bourke said the €12,000 budget set aside for tackling Japanese Knotweed was “a drop in the ocean for a town the size of Carrick-on-Suir”, questioning who’s responsible for the invasive plant.
“It’s along our waterways and requires a special spray that is very, very expensive,” the Fianna Fáil councillor said.
In reply, district engineer Willie Corby said a number of private areas around Carrick-on-Suir have Japanese Knotweed. “We will be encouraging property owners to see the need to sort out this problem,” he added.
The council has advised property owners not to strim, cut, flail or chip the plants as tiny fragments can regenerate new plants and make the problem even more difficult to manage.
It is also advised not to dig, move or dump soil which may contain plant material as this can contribute to the spread of Japanese Knotweed.
