Recording Knotweed in Devon

Without surveying and recording the distribution of Japanese Knotweed there is no way of knowing where it occurs, whether it is increasing and the typical habitats it colonises. Knowing the full extent of the problem of Japanese Knotweed colonisation in the county will help the Devon Knotweed Forum identify priorities for control and management. It is therefore important to report any sightings of the plant in the county to the Devon Biodiversity Records Centre. Please note the Devon Biodiversity Records Centre are not responsible for controlling Japanese Knotweed and do not provide general advice on Japanese Knotweed.
