Horticulture is not all about growing things. If everyone was out planting trees, the World would eventually be overwhelmed with forest. It is sometimes necessary to cut trees down. There are several at work that we have been wanting to cut down for quite a while. Some are structurally deficient enough to eventually become hazardous, which is unacceptable in public spaces.
Even here among some of the oldest trees in the World, nothing last forever. Coast live oak, like that in the picture above, has potential to survive for centuries, but eventually succumbs to decay and disease. If fact, this particular specimen is doing it right now. If not cut down soon, it will eventually fall onto an adjacent building and a parking lot below. Its days are numbered.
Literally, it will be cut down on Monday morning, along with a few other coast live oaks and bay laurels in the neighborhood. The orange ‘X’ on the trunk is so faded from the delay of getting this done, that is it barely discernible. (Actually, the can of spray paint was empty.) The trunk and even the main limbs are so rotten that there will not be much firewood left to cut and split.
Cutting this tree down may seem to be unnatural, but so was pruning it for decades so that it would not fall down. It is impossible to say what situation this tree would be in now without past or present intervention. I am more concerned with how it and other trees interact with their surroundings, and the safety of everyone involved. We can not always let nature do as it pleases.
Forest fires are very natural components to our local ecosystems, but because so many of us live here, significant effort and resources are expended on containment!
