Fluvial erosion is undermining the stability of a High Voltage electricity pylon located on the banks of the River Mersey, near Carrington, Manchester. A major UK construction company is leading a project to stabilise the pylon, but the works are complicated by the presence of Japanese knotweed and Himalayan balsam, which are present as huge infestations to the area.
There is a duty to ensure that the works do not spread the invasive weed problem to other areas of the site or to off site. To this end Japanese Knotweed Ltd (JKL) were contracted to formulate a management plan, which set the following objectives:
- Identify and record the extent of Japanese knotweed and Himalayan balsam
- Control the spread of these plants using approved systemic herbicides
- Secure working areas of the site from the risk of knotweed and balsam contamination
- Prevent the translocation of contamination to other areas of the site or to off site
Phase 1 of the works began in the autumn of 2015, with all areas of Japanese knotweed on and within 7m of the proposed pylon access routes and works areas being treated by JKL with a selective herbicide (approved by the Environment Agency for use near water). Pylon works commenced in 2016, following the excavation of knotweed and balsam from the working areas and relocation of the excavated material to adjacent infested areas of the site. During the project the site will require regular control treatments and monitoring, to ensure that invasive weeds are not being disturbed and spread by the pylon works.
