Its true that there are many CA's out there that just have it for the paper, but there are many more who can do all aspects of tree work. The big shows have lots of guys who are CA's that would have no clue in a tree. I met several BCMA's in cali that had no clue as far as real field work goes. The small mom and pop deals however, like the many here, are CA's and can do epic level Jedi chit in the tree. All depends on the individual. I have often said, and sometimes with negative feedback. That if you are a CA, than you should be able to do the work aloft. That is the definition of a Arborist. Someone who just looks up from the ground is a Botanist or Biologist. Now, with all that in mind, if you are upper management, run a desk and a CA, but used to be in the field. Then your still a CA, just a smarter one! Doing removals is just one aspect of it. I know several guys who are real good at running a saw and bombing the chit out of a tree, but have no clue if they where asked to prune a tree for structure. To them, pruning means "point at the one ya want gone" I would rather prune a tree than remove it. Ya can only remove a tree once, ya can prune it and return for several years, making much more money off that one client than the one time ya kill it.
