    Why floating pennywort is a problem in Carrickfergus

    On Carrickfergus properties, floating pennywort grows up to twenty centimetres a day, choking ponds, ditches and slow water and blocking drainage and angling access. In Carrickfergus, Japanese knotweed and Himalayan balsam spread along the Belfast Lough and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Carrickfergus Castle and Woodburn Forest, along with new housing on the edge of town towards Greenisland and Whitehead, are where we most often find established stands.
