What are the modifications required for drone canopy leaf sampling?

Make sure the prop blades are protected. Modify the tail to include a collection device.  A very sharp blade at a sharp angle allows twigs to be cut off and often to remain caught in the space between the blade and tail. Learn how to drive the drone using the camera. For more on drones […]

Can madrone die from sudden oak death?

Does the sudden oak death pathogen sporulate on madrone like it does on California bay laurel? Sudden oak death can kill small madrones and cause significant dieback of larger madrones.  While Phytophthora ramorum (the pathogen that causes sudden oak death) does sporulate on madrone, making in an infectious host, it is not a very effective […]

Sampler Drones for Forestry Reseach

The Forest Mycology and Pathology Lab at UC Berkeley has developed a new method for sampling forest canopies. The Sampler Drone is a modified DJI Phantom 2 Vision quadcopter that is lightweight, compact, and exceptionally agile. The Sampler Drone uses GPS positioning and gyroscopic axis stabilization to provide a stable aerial platform for collection of […]
