The 9th annual 3 Rivers Clean Up (3RCU) runs from 3 June to 24 June.

For 3 weeks, people across Bromley, Greenwich and Lewisham get into their local rivers to remove invasive non-native plant species – mainly Himalayan Balsam – and larger rubbish items.

Himalayan Balsam tend to smother other plants and weaken the river banks. By removing balsam in June we can help stop it bursting its seed and using the rivers to spread more plants across the area.

This helps keep our rivers and river banks healthy for a range of wildlife – plants, insects and mammals – instead of being dominated by single species. Taking larger items of waste out the river helps avoid the build of materials in the river which can add to flood risk – it also gets rid of waste which can endanger wildlife on and in our rivers.
