Horridculture – Tree Preservation Ordinances

Padding should protect these London plane street trees from minor altercations with machinery that will be used to demolish the associated buildings and construct new buildings.

Much of my work involves inspection of trees to assess health, stability and structural integrity, and subsequent composition of associated arborist’s reports to document such assessments. These reports are necessary for the issuance of permits to remove mature trees within many municipalities. They are only effective for that purpose if they recommend and justify removal.

If there is nothing wrong with the health, stability or structural integrity of subject trees, removal might be justified for other reasons. For example, the removal of superfluous trees might be justified if it would promote healthier development of remaining trees. Trees that disperse roots that are beginning to damage adjacent infrastructure might likewise need to be removed.

It seems like it is too much to be concerned with for something that property owners should not need permission to remove from their own property. For what people pay for property here, they should be able to do whatever they want to with it. However, mature trees are considered to be assets to their respective Communities, and components of the collective urban forests.

These majorly and justifiably controversial concerns are actually not the the only difficulties associated with municipal tree preservation ordinances.

While a young coast live oak in the extreme corner of my garden was not quite big enough to require a permit for removal, I asked the next door neighbor if he would like it to be removed before the roots damaged his driveway. I explained that if we waited any longer, the tree would be protected, and that a permit to remove such an exemplary tree would not likely be issued.

Tree preservation ordinances are often the motivating factor for the removal of trees before they get big enough to be protected! I was fortunate that my neighbor wanted my oak to stay.

Another Johnny Appleseed


Just to be clear, I earned the title of Johnny Appleseed before my colleague Brent Green did. While Brent was secretive about our tree planting projects in Los Angeles, I was not so about our similar projects in Los Gatos. While Brent’s neighbors wondered where their new street trees were coming from, mine read about their new park trees in the Los Gatos Weekly Times.

In fact, the exposure from that article is how I started my weekly gardening column in the same newspaper just a few months later, in October of 1998. Los Gatos is a smaller town than Los Angeles is. Secrecy was not an option. Sadly, our projects in Los Gatos, and then in Scott’s Valley, did not continue. We concentrated our urban tree planting efforts in Mid City Los Angeles.

The tree planting projects that I am referring to are our Birthday Trees that I wrote about last January. As I explain in that article, Brent had been wanting to plant trees in the formerly blank and broad medians of San Vicente Boulevard in Los Angeles. I just happened to be able to supply such trees from those at the farm that got a bit too past their prime to be marketable.

I do not intend to be redundant to that article, but want to share this video, Johnny Appleseed. As much as I hate to admit it, Brent is much more entertaining than I am. (I should later share one of my old videos from Gardening By The Yard, so you can compare.) I should probably look through more of Brent’s old videos to see if there are others that would be interesting.

If I had more time, I would write more about Brent’s work to improve the urban forests of the Los Angeles Region.

Birthday Trees


The big wide medians of San Vicente Boulevard in western Los Angeles had been lacking trees since the Red Car Streetcar rails were removed decades earlier. My colleague, Brent Green, had been wanting to add trees to the medians since he was a little kid, and then became intent on doing so after he became a renowned landscape designer in the region.

At about the same time, I was a nurseryman. In my work, it was not uncommon to dispose of a few items that were unsaleable. Sometimes there were entire crops of unsaleable plants; and in 1997, I needed to dispose of a group of coastal redwoods that had very minor kinks in their trunks.

That gave Brent an idea.

He wanted me to bring some of the trees to Los Angeles to plant them in the medians of San Vicente Boulevard just south of the Miracle Mile District. We were sort of skeptical about their ability to adapt to the climate; but were willing to give it a try, and possibly give the trees a second chance. We planned to install thirty coastal redwoods for Brent’s thirtieth birthday on January 18, 1998.

Well, the trees were not happy there, and did not last long. However, they were the first of what became an annual tradition of planting trees on Brent’s birthday, January 18. The number of trees is determined by Brent’s age for the respective year. For example, we planted thirty coastal redwood trees on his thirtieth birthday, and then planted thirty-one manna gum trees, Eucalyptus viminalis, on his thirty-first birthday, and so on.

After a few more years, there was not much space on San Vicente Boulevard, so Brent started planting street trees in the parkstrips of streets that could use more trees. The original trees in San Vicente Boulevard needed to be removed for the installation of the Metro Rail, but they were nice while they lasted.

This short video is about what the tradition has become now that Brent will be planting fifty birthday trees.




If my articles start to seem somewhat deficient, it is all Brent’s fault. Really. I will need to be spending more time with GREEN; Greening Residential Environments Empowering Neighborhoods. It is a much more important project than what I am doing because it involves planting more street trees and trees in public places in Los Angeles, maintaining trees of the urban forest, and enforcement of tree preservation ordinances within Los Angeles. Brent has been very active with GREEN since we were in school, and it has really make a big difference in the parts of Los Angeles that have benefited from it.

I will need to be writing for the website and other social media outlets for GREEN, and consulting with others doing the same. To make matters more confusing, I will be working on yet ANOTHER projects later in January as well, but I can explain that a bit later.

When I started my writing here, it was initially intended as an outlet for my weekly gardening column. After a while I started recycling articles from last year as well. The space in between is filled in with my ‘elaborations’, which are supposed to be related to horticulture, but are sometimes about other funny but unrelated topics.

I hope to continue in such a manner than no one notices that I am also working on other projects. In fact, I believe that the other projects might be interesting topics here, which means that the different projects may actually compliment each other. We will find out as we go along. I will post updates about GREEN, which will soon be known as something else. I am sorry that the Facebook Page for GREEN has been deleted while we develop a new one. Otherwise, I would post a link to it.
