CRT have said that they are starting a winter tree and hedge manangement programme. They say that the works will focus on preserving navigation and ensuring sightlines are kept clear, rather than cutting back every metre of overgrowth. We actively manages vegetation all year round, but large-scale activities are best suited to winter when the waterways are quieter and disturbance to wildlife is minimised..
We have a list of the target areas and you can see it here, with the accomanying qualifications. If you know of other places, pleas elet us know and we can follow up.
Dont forget that all towpaths should be cut to edge and woody growth removed by the end of March 2020.
