Keep it Clean! (2020 logo)

Many of our trees are under threat from pests and diseases, and human activity is a key factor in their spread. We can reduce the spread of pests and diseases by undertaking basic biosecurity measures day to day to minimise the amount of soil, water and plant material we carry between sites. Don’t give tree pests and disease an easy ride! https://www.gov.uk/guidance/prevent-the-introduction-and-spread-of-tree-pests-and-diseases
