During 2016 Tees Rivers Trust undertook a significant body of work in relation to Invasive species. This work will continue throughout 2017.
With the help of trained volunteers, we have tackled 54Km of giant hogweed (108Km of riverbanks), on the Tees, Leven and Skerne. Planned work for 2017 will see a further 28Km of river added to this.
Horizon scanning for Chinese mitten crabs is on-going with PD Ports taking a lead role in this work. They have 45 members of staff working on the estuary and all have been trained to monitor for signs of the invasive crab. We also have volunteers monitoring the mouth of the estuary.
We are continuing our work with the international research group CABI, in field trials of biological control of Japanese knotweed and in 2017 we will continue this work as well as trialling a new biological ‘Rust’ spray for controlling Himalayan balsam.
