Knotweed Risk in Kilmarnock

Japanese knotweed has been identified in the Kilmarnock area, covering postcodes KA1, KA3. The plant spreads through its underground rhizome system and can be found along railway lines, waterways, in gardens, and on development sites.

East Ayrshire has moderate knotweed risk due to former coal mining sites around Kilmarnock and the Irvine Valley. Victorian housing in Kilmarnock and the railway corridor to Glasgow harbour established infestations. Former industrial brownfield land provides ideal disturbed ground for continued colonisation.
