NE Non-Native Invasive Species

North East Non-Native Invasive Species (NENNIS)

2018 - 2021

This project aims to tackle Invasive Species locally! By training volunteers in safe pesticide use, vast areas of Aberdeenshire are being treated for invasive plants like Giant Hogweed, Himalayan Balsam, Japanese Knotweed and Pirri-Pirri Burr. These dangerous plants can pose a major threat to native plant species, cause problems with erosion and flooding and be costly and time consuming to control. The project is led by The River Dee Trust and Aberdeenshire Council and funded from Leader. To read more about the project please click here.

Forum Launched

A local forum has been established to discuss the best way forward and help lead on invasive non-native plants removal. Click here to find out more.

Introducing your new Invasive Species Co-ordinator - Estee Farrar

I would like to introduce myself, now that I have officially started work as the Invasive Species Coordinator, at the River Dee Trust, replacing Calum Hislop in the role.  I am really looking forward to working with everyone over the next eighteen months. 

Within this role I will be splitting my time between working on:

  • The NENNIS (North East Non-Native Invasive Species) Project, in partnership with Aberdeenshire Council, working across north east Scotland to identify and control problematic invasive plant species; and
  • SISI (Scottish Invasive Species Initiative) focusing on controlling the three invasive plant species Giant Hogweed, Japanese Knotweed, Himalayan Balsam and American Mink in the Dee, Don, Cowie and Carron Catchments.

I will endeavour to catch up with as many of you as possible over the next little while, however, please find my details attached.

SEPA have produced new guidance on the regulations controlling the spraying of invasive plants adjacent to watercourses. This is included within General Binding Rule GBR 23. 

New notebooks have been purchased through the project to assist with the survey and plotting of invasive species throughout the North East. These are available for loan to interested individuals and groups. Training in their use will be provided.

Training in the spraying of invasive plants has been provided to 12 people, who are now able to undertake the control of Giant Hogweed, Japanese Knotweed, and Himalayan Balsam through their particular community group or fisheries trust.

Pirri Pirri Bur is a relatively new invasive plant which we will be focusing on it the months to come.


A new leaflet and three double-sided banners have been produced to help spread the word of the project and provide information to volunteers.
