Invasive Species control in the Forth 2018

The fight against invasive non-native species along rivers in the Forth continued during 2018 with a number of community led actions taking place. The Trust also led on a number of work days to tackle INNS with the support of contractors and volunteers.

On the River Carron, funding was provided by EB Scotland who distribute the Scottish Landfill Communities Fund to get support from contractors to continue Japanese knotweed control along the Bonny water and river Carron. This was also supported by Falkirk Council.

Although the Carron has been treated for a number of years, there is still Japanese knotweed stands along the river corridor which are being treated. It is however important to note that the reduction in number of, and size of stands has reduced which is encouraging but some stands are being more persistent than others. We have found a few of the larger stands have returned year on year with highly stunted growth which makes it difficult to treat.

In other parts of the Forth, volunteers done a fantastic job tackling giant hogweed along the Allan Water during April and May. The Trust was able to support the communities of Dunblane and Bridge of Allan with the supply of chemical and equipment to continue control along the water course.

Elsewhere, the Trust carried out control of Japanese knotweed in the Loch Lomond & Trossachs National Park along the Teith and Forth systems. This was supported by volunteers and many riparian landowners.

Finally, in the Almond & Avon catchment INNS were controlled as part of the RiverLife: Almond & Avon project with our dedicated volunteers from the local angling clubs and community members. Control was able to take place along the full length of the River Avon and Almond thanks to this support and funding from the Heritage Lottery Fund.

A massive thank you to EB Scotland, Falkirk Council, Heritage Lottery Fund, SEPA, Loch Lomond & Trossachs National Park, riparian landowners and all of the volunteers right across the Forth who supported INNS control during 2018.
