Biosecurity - Keep it Clean

Keep it clean logo

Many of our trees are under threat from the spread of pests and diseases. Human activity is a key factor. Biosecurity measures minimise the amount of soil, water and plant material we carry between sites. By taking some very simple routine actions set out here on our Keep it Clean pages we can reduce the spread of pests and diseases and give control measures a better chance of success.

Tackle it!

We need to act quickly and decisively, creating resilient woodlands and trees for the future. We need people working with trees to adopt good biosecurity practice every day - this is key to limiting the spread of pests and diseases.
