Aerial Surveillance to Detect Pests and Diseases - February 2023
This talk will explain how the Forestry Commission use aerial surveillance (helicopters and drones) to survey trees for signs of poor health, disease and/or pest infestation. We will use Ips typographus as a case study to show how this work feeds into pest outbreak response work. We will also talk about the signs and symptoms looked for during drone surveillance for a range of emerging pests and diseases.
