Plant health and biosecurity

This section is being actively worked on. 

The Landscape Institute is concerned with plant health and invasive plant species. We aim to raise awareness and understanding among our members about plant health and biosecurity issues.

Through liaison with liaison with bodies such as Defra, FERA, the Tree Council, and the Scottish Centre of Excellence, the LI’s plant health and biosecurity group has helped curate information, produce training events and technical resources, and keep members up to date with the latest developments in biosecurity.
