Problem plant species spotted during survey (UK)

Some non-native plant species can spread quickly and outcompete native vegetation, reducing habitat quality and biodiversity. Recording these “problem” or invasive plants helps identify areas where management may be needed.

The Non-native Species Secretariat have a comprehensive set of ID sheets that include all of these ‘problem plants’ – links provided below: 

• Himalayan balsam
• Japanese knotweed
• Giant hogweed
• American skunk cabbage
• Curly waterweed
• Floating pennywort
