Invasive species survey- training session

June 4 @ 5:30 pm - 7:30 pm

Citizen Scientists completing an ObstacEELS survey

We are looking for volunteers to help conduct invasive plant species surveys along the Hogsmill, Beverley Brook and Wandle.

Invasive plant species such as Himalayan balsam and Pennywort have a detrimental impact to our waterways and we need your help to find and log them so we can target action to remove them.

This activity involves bankside surveys of stretches of river to map and record the presence and abundance of six key invasive plants.

The surveys will take place during June-July 2024.

As a volunteer, you can choose which stretch of the river and at what time to conduct the survey, within the survey period.

The survey will be conducted from the riverside path, in areas that are accessible and where the river is easily visible.

The training session will take place at:

Raynes Park Library, 21 Approach Rd, Raynes Park, London SW20 8BA
