Aquatic plant management focuses on understanding the mechanisms that enable the spread of non-native aquatic plants, and on economic and environmental impacts. General information on the ecology and control of aquatic weeds and riparian plants – to regulatory authorities, flood defence organisations and nature conservation organisations – can help to prevent the establishment of invasive non-native plant species.

Aquatic plants are found in lakes, rivers and ponds across the UK and play a vital role in all aquatic ecosystems. They produce oxygen, absorbing nutrients and helping to improve water quality, and stabilise lake shores and river banks, thereby protecting them from erosion. Aquatic plants provide food and important reproductive and cover habitats for fish, invertebrates and wildlife. They also play an important role in supporting recreational activities such as fishing.

Relevant webpages on aquatic plant ecology, monitoring and management will be posted here soon, covering our projects on conserving rare species as well as managing invasive species.

Aquatic plant datasheets

A number of the former datasheets on common aquatic and riparian weeds are awaiting revision. Please note that the use of herbicides in Europe is governed by EU Plant Protection Products Directive EU/91/414.
