Plant Invaders

Plantlife's survey of three of Britain's most invasive plants

Many imported plants are fast growing and can quickly become invasive in the British countryside, taking over natural habitats, out-competing native plants and blocking up ponds and rivers. Most problem species are garden escapees and sold in garden centres. Control and eradication of these species is difficult and expensive. Plantlife is campaigning to ban the sale of the most destructive plant invaders.

But we need your help. Please look out for these plant invaders and let us know where you see them (in gardens, local parks, along waterways) by filling in our online survey form. And don’t forget to let others know that these plants are a problem! Results from the 2006 survey are available below.

Please click on the 'Fill in the online survey form' to submit your results online. If you need paper copies of the survey postcard, please either download the PDF or call the survey hotline on 01722 342755. If you need assistance with any aspect of the survey, please call 01722 342756.
