Here is a lovely tree, it’s shaped like an Italian Stone Pine, or Pinus pinea, but it’s actually a Monterey Pine. CCTD has us maintain this tree once a year since it is in a very small back yard in the Marina District. I think the before and after pictures speak for
Campbell has shown me the importance of call and response, always keeping a clear line of communication between the ground crew and the climbers. The more eyes the better. Safety always comes first.
If you look closely or click on the picture at the left, you can see me working above the high voltage lines. It was very important that my tie in point be strong, that I communicate all of my actions loudly and clearly, and that I have complete control over every cut that must come down. You don’t want to mess with high voltage.
Four years ago I was working in Pacific Heights with CCTD. I was on the ground crew. Suddenly there was a giant explosion. All of us could feel the electricity in the air. All of our climbers came whizzing down to the ground. 200 yards away another crew was working over the high voltage lines. Someone had accidentally dropped a branch and it must have connected the positive and the negative lines. Fortunately no one got hurt. PG&E had to come out and restore the power.
To the right is the completed work of art. Notice the natural flow. Notice that the tree still has a beautiful shape without looking too manicured. Notice that you can even see some of the interior structure. Fetter has opened up the outer canopy to allow light to enter the inner canopy. This makes for good long term heath and structure. The tree also looks graceful and contained.
Since we were working on a hill one of the biggest challenges was moving the brush. We used ropes to help us get up and down the incline. Pictured to the right is Jordan, modeling the rope system. He’s Christopher Campbell’s newest crew member.
These trees were approximately 40 foot Eucalyptus globulus, Blue Gums. These fast growing trees from Australia can grow up to 90 feet in their first ten years. After15 years the growth rates slow down significantly.
The fast growing Blue Gums are one of the four main trees used as the original overstory for the creation of Golden Gate Park. The other three are the Torrey Pine, the Monterey Pine, and the Monterey Cypress.

Here’s a picture of Mikey felling some of the trees. He loves his chainsaw.
We needed to thin out the grove for fire safety too. The bark of the Blue Gum is thin and sheds easily. It’s also highly flammable.
Here’s a before and after picture…
It took 8 hours and 8 guys and three truck loads of debris.
Monterey Cypress, Cupressus macrocarpa are among my favorite trees to climb. They are really tall, and really sturdy. We never work on them when it is damp. Working in a damp Cypress can spead Cypress Canker. So if I’m working in a Cypress it’s probably a beautiful day and I can see for miles.
