Report an invasive non-native species in Cumbria

Have you seen a new patch of Himalayan balsam recently, or seen New Zealand Pygmyweed were you haven’t previously? Report it to us using the Survey123 form below in the Derwent INNS map so we know about it!

Not sure how to ID species? The GBNNSS have ID guides available free online, as well as online training. If you are part of a group who would benefit from a free training session on INNS ID and biosecurity, get in touch with Izzie at

  • If you identify an INNS on a waterway in the Derwent Catchments please let us know using this form so we can add it to our records, shown in the below map
  • Remember, do not remove it from the area, always leave invasive species where you find them, to prevent any further spread
