Brock Mayo climbs a sugar pine to collect pinecones in Cottage Grove, Oregon. Snatching up these cones is key for studying diseased trees and getting new, healthy ones in the dirt. Problem is, by the time those cones hit the ground, the seeds are history. So climbers like Brock need to scale up to 100 feet to grab them fresh from the treetops. #treeclimber #forestrywork #canopy #conservationmatters #pnwonderland | Oregon Field Guide
