NINE ELMS RIVERSIDE
Over a year ago a complex web-like root structure was observed on a listed, historic river wall. This Spring we have confirmed the root system to stem from Buddleia Davidii. In riparian areas this species of plant is causing untold damage as each plant drops up to 40 roots which are typically 3-4 metres long. The root system expands over time and delaminates the brickwork. The reason why the plant drops so many roots is that a river wall lacks the nutrition available from soil and therefore the plant needs a massive root system to supply the food needed for the plant to thrive. The micro climate of the Thames has shown that the plant continues to grow throughout the year with 2m annual growth not being uncommon. The roots can grow in thickness by 5-7mm and as we have evidenced they have considerably more strength and hydraulic force than Japanese Knotweed. We are now advising on six projects where Buddleia is causing considerable damage to river walls up and down the Thames.
We are the only specialist restoration firm to properly understand how to remediate Buddleia on historic river walls and provide a long term robust solution. We are also the only specialist restoration firm to have the appropriate Commercial Operators Licence to operate in the marine environment.
