Need pictures for research study

[BC_Logger]

Hello Everyone

I am working on a research project related to visual perception of wind firming techniques, specifically in second growth coastal conifer stands. I would appreciate any photos of single trees or stands demonstrating any of the following techniques,

pruning by a helicopter
topping by a helicopter

pruning by a climber (spiral)
topping by a climber

any help will be greatly appreciated
