Plant pathologists here have been trying to get an eye-in-the-sky project off the ground that would use airborne cameras and thermal imaging detectors to map at risk trees, long before symptoms are visible to the human eye. But so far  the funding bid has been rejected. The technology has already been successfully used in Australia for 10 years to arrest the spread of serious tree diseases.
