Why hire a climber?

Safety

The number one reason you want to hire a climber is safety. Climbers that make it through the first few years in 'the canopy', possess a strong kinesthetic learning modality.

There is a general consensus that there are 4 Learning Modalities; verbal/linguistic, visual, tactile, and kinesthetic. This is a big part of modern educational philosophy. Education was centered on rote memorization until John Dewey (1859-1952) made his case for experiential learning. 

I believe that the 4 learning modalities can be understood in a simple way that everyone can understand; speech, sight, touch, and climb.   

Naturally, when considering tree structure, it's advantageous to hire someone who has a strong climb learning modality. They can judge the safety and weight distribution of stems, limbs, branches, and root systems due to their previous experience up in the trees. 

Vebal/Liguistic thought is linear thought. This communication mode is in lines of text.  For example,an actor's lines in a movie or play. Lines have one measurable dimension; length. Therefore, it is 1 dimensional. It is a lot like a USB cord; Universal Serial Bus.

Visual thought is a planar thought. This communication mode is in pictures or planes. Planes have two measurable dimensions; length and height. Therefore, it is 2 dimensional. It doesn't have to be a picture. Think of how math problems progress downward on a sheet of paper rather than a serial line going back and forth.

Tactile thought is a volumetric thought. This communication mode is in objects that have volume. Objects have three measurable dimensions; length, width, and height. Therefore, it is 3 dimensional. Again, it doesn't have to be an object, there is a much broader range of tasks that fit in here.

Kinesthetic thought is a structural thought. This communication mode is in the structure of the nature of things. 

The observable universe seems to be structured with Fractals. Each fractal pattern is a fourth identifiable dimension; length, width, height, and the fractal pattern. Therefore, it is 4 dimensional. 

The fractal pattern exhibited in trees is the Fibonacci Sequence. 

Tree climbers use the forks in these fractals in order to get around the tree using rope and saddle technology. They also prune trees in order to maintain this forking pattern. 

Ideally, one branch forks into no more than than two future branches. This provides the strongest branch attachments ensuring the safety and longevity of the tree. This natural forking pattern cannot be improved upon. 

Conversely, improper pruning results in more than two new branches stemming from a fork, or node. This creates much weaker attachments that usually lead to future branch failures at the point of the pruning cut.  

Interesting Note

I have observed that the 4 preferred learning modalities, when used together, are greater than the sum of their parts. Each modality is clearly identifiable in the Technological design loop. 

After a problem is encountered, it gets researched, and then there are several steps which organically lead to new inventions and innovations. 

It begins with the ideation of many solutions in a multidisciplinary fashion; kinesthetic. 

Next, one solution is built and refined; tactile. 

Then, the new invention is tested and evaluated; visual. 

Finally, the solution is communicated to other people who want to solve the same problem; verbal/linguistic.

This happens without consciously knowing it on a personal and group level of problem solving. 

Alternatively, engineers and technologists consciously design using this cyclical process.
