Invasive Weeds

What are invasive weeds?

Invasive weeds include Japanese knotweed, giant hogweed and Himalayan balsam.


Invasive weeds disrupt ecosystems by dominating cover; preventing the establishment of desirable plants and damaging overall biodiversity value. 


These weeds are legally protected under Schedule 9 of the Wildlife and Countryside Act (1981, as amended) in so far as it is an offence to 'cause, or otherwise allow them to grow in the wild.' If such plants occur on your site, you have a legal responsibility to ensure they do not spread. They are also a 'material consideration' in planning decisions and any ecological report being submitted in support of a planning application must include a strategy for eradication. Such plants must be removed from site pre-commencement. 

How can we help?

We can survey your site for invasive plants and provide you a plan for eradication. 

Hybrid Ecology are also trained in chemical application and can therefore eradicate invasive weeds.


We hold the NPTC Certificates of Competence PA1 and PA6aw (application to water). The aw application endorsement is required by the Environment Agency should invasive weeds need treating close to a watercourse. Hybrid Ecology can apply to the Environment Agency for a licence and treat on receipt of approval.
