Along a slightly different line, I feel, from my working background prior to teaching, that I learn more if I learn it on the job. I enjoyed learning the most when it came as part of the work day, whether I learned it my self, or had a "teacher" on the site. I think this would be a particularly good approach to helping develop a PHC program, helping the crews to recognize the relationships between tree biology, the local environment (above and below ground), the cultural pressures of the owner's desires and the tree care companies' philosophies.
Do any of your companies utilize this sort of training? Would it be something that you think would be beneficial? If a small company, possibly several could go together to share overhead costs, such as travel. I am always thinking of new ways to see the country and keep a little income flowing for when I retire in the near? future.
Thanks for your thoughts.
PS. I am qualified in brush dragging and other fine arts of the arboreal world!
