Rivers & watercourses

Invasive plant work along waterways.

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.

We consider access, biosecurity, the watercourse and surrounding habitat alongside the invasive plant itself.

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 ↗

The site comes first

Work that accounts for the water around it.

Japanese knotweed, giant hogweed and Himalayan balsam can all affect river corridors. A useful response starts with correct identification, the extent of the growth, access, the watercourse 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.

River site enquiry

Tell us what is growing.

Share the watercourse location, photographs if available and what the land needs to be used for.
