Surveys, management plans and targeted treatment for riverbanks, water-adjacent land and connected corridors.

Field experience

River work is a speciality.

Our invasive plant experience began on Sheffield’s rivers in 2012, including practical Japanese knotweed containment and herbicide work. That background continues to inform how we approach riverbanks, water-adjacent land and environmentally sensitive sites.

Japanese knotweed, giant hogweed and Himalayan balsam can all affect river corridors. We identify the plant, assess the extent of growth and consider access, the watercourse, surrounding habitat and how the land is used.

We discuss the treatment area, timing, biosecurity and follow-up before agreeing a plan. The scope depends on the plant and the site.

Direct services

From survey to ongoing control.

01 / SURVEY

Identify and record

Assess visible invasive growth and the site conditions that shape a practical response.

02 / PLAN

Agree the programme

Set out a proportionate management plan, treatment area, timing and monitoring approach.

03 / TREAT

Treat and follow up

Provide targeted herbicide treatment and follow-up visits as agreed for the location.

In England, herbicide use in or near water requires an Environment Agency agreement in advance. We assess that requirement for the proposed work. Read the Environment Agency guidance ↗
