Why giant hogweed is a problem in Letterkenny
On Letterkenny properties, giant hogweed sap causes severe phototoxic burns and long-term light sensitivity, which makes it a genuine safety issue on footpaths, riverbanks and school boundaries. In Letterkenny, Japanese knotweed and Himalayan balsam spread along the River Swilly and its tributaries, where floods and riverbank works carry rhizome fragments downstream. Verges and green spaces around Lough Swilly and Glenveagh National Park, along with new housing on the edge of town towards Ramelton and Milford, are where we most often find established stands.
