Volunteer Removal at Burrs Country Park
On 23 May, during the school half-term break, Bury Council invited residents of all ages to help eradicate Himalayan balsam from Burrs Country Park in Greater Manchester. The event repeats a similar effort last year and stresses that the plant can be pulled by hand while still short, requiring no prior experience.
Background
Himalayan balsam (Impatiens glandulifera) is a tall annual native to the Himalayas, introduced to Britain as an ornamental garden plant in 1839. Each plant produces hundreds of seeds; seed pods launch seeds up to seven metres, and seeds remain viable for two years in water. Flowering runs from July to November, attracting bees. Rapid growth allows the species to dominate riverbanks, wet woodlands, and ditches, blocking waterways, raising flood risk, and promoting bank erosion.

Guidance on Removal
Bury Council stresses that removal is “very easy to pick up” and encourages participation regardless of experience. The RHS advises on-site destruction of harvested material and warns against placing it in garden waste bins. Possession is not an offence unless the holder intentionally cultivates or spreads the plant, though authorities may order control measures. The Environment Agency requires prior notification and mandates that a registered waste carrier transport material to an authorised disposal site.
Conflicts & Gaps
All sources agree on the plant’s biology, legal status, and disposal protocol; no contradictions appear. However, specific data linking Himalayan balsam to recent flood events in the Bury area are not provided.

- “it's very easy to pick up” — Bury Council spokesperson
- “Instead, the plant should be destroyed on site after removal.” — Royal Horticultural Society
- “Destroy them on site but do not put Himalayan balsam in waste bins.” — Royal Horticultural Society
- “If removal is necessary, the Environment Agency needs to be informed and you must use a registered waste carrier and an authorised disposal site.” — Environment Agency guidance
Future Steps
Following the May event, Bury Council plans additional removal sessions through summer, coordinated with the RHS and the Environment Agency. Monitoring will track regrowth and the effectiveness of on-site destruction, while updated disposal instructions will be shared with volunteers and landowners.
