Survey

INNS Mapper relies on records of non-native plant species contributed by members of the public, Yorkshire Invasive Species Forum members and other organisations. Once logged in, this section will allow you to explore the rivers that have already been surveyed within Yorkshire, giving you an overview of what's been done, and what we still need to do.

  • For our partners and other related organisations, this map is designed to help you to plan which stretches of river would be most effective to survey in the near future.
  • For our volunteers and members of the public, it is for you to see how you are contributing to survey efforts across the county.

Please register (it's quick and easy to do) or sign in using the form on the right to explore INNS mapper data and upload your data.
