What is an RCA?

When I tell people I’m a consulting arborist they often ask what is that? Everyone is familiar with tree care companies, but not so much what the role of a consulting arborist. The common conception is when there is a tree problem, call up a tree contractor and have them do the work. Yet, there are many tree problems that require expertise beyond a tree care company. When a tree has a change in condition or conflicts with infrastructure, a consulting arborist is required to assess the situation and make recommendations. Consulting arborists have one or more certifications.  The primary … Read More

A “Super” Way to Watch the Game!

Yesterday, while taking our usual walk through North Park heading toward Balboa park, my wife and I came across these two guys comfortably hanging out watching the Superbowl pregame show underneath towering Eucalyptus trees. They worked for a company that integrates new technologies and were promoting wireless, cable-less TV under the trees! It was really pretty nice to be able to sit under the trees on a beautiful San Diego day watching the game, best of all worlds! PS, I did inspect the trees surrounding the site for any significant defects! PSS, I don’t know anything about their company but … Read More

A Better Way to Protect Trees and Pedestrians

Through a business acquaintance, I had the good fortune to meet with Mr. Christian Rodriguez, a company representative from Blue Drop, Inc.  We met at a downtown San Diego street intersection where Blue Drop, Inc. had a contract with the City of San Diego to replace old cast iron tree grates with their new product called Safe Path. Tree planters within pedestrian sidewalks are typically small confined spaces surrounded by concrete with lots of pedestrian traffic.  Tree grates were installed around the planter pit primarily to protect people from tripping over tree roots.  The grate also allowed watering to occur beneath … Read More

Let it Burn or Suppress It? US Park Service vs Cal Fire Policy

This past summer brought us the gigantic Rim fire that devastated Yosemite National Park and surrounding communities. Over 4,900 firefighters operated under a unified command, however when the fire crossed over into the boundary between state and national park land, the National Park Service took a very different approach than Cal Fires (California Department of Forestry and Fire Protection).

California Trees Under Attack, Are You Part of the Problem?

We have seen an increasing number of disease pathogens and insects attacking many tree species throughout our country.  In Southern California, the gold spotted oak borer, (GSOB), (Agrilus auroguttatu), first introduced in San Diego County between 1990-2000 has spread into Riverside County and is expected to spread throughout California.  This pest specifically targets the Coast Live Oak and Black Oak, (Quercus agrifolia, Quercus kelloggii), both oaks comprising a major part of our red oak forests throughout California. The adult female beetle lays eggs on host trees mainly June through September, the eggs hatch into larvae which bore through the outer … Read More

What to do With Your Xmas Tree?

Fortunately, most municipalities now have recycling programs for green waste, making it easier for homeowners to recycle their used Xmas tree.  Recyclers grind or shred trees into a mulch which is then composted and eventually becomes available as a bulk or bagged mulch product.  This is certainly a preferable option than the “old days” when trees were commingled with regular trash and buried in landfill sites. If you have a large tree, prune off some branches and reduce the overall size to ensure local curbside pickup.  If you have the room on your property, you can do your own recycling … Read More

At Yosemite, Infrastructure Out to Benefit Giant Sequoia’s!

Read an article in the Los Angeles Times concerning upcoming changes at Yosemite National Park. There is a proposal to remove public parking, a gift shop and tram operations in an effort to minimize impacts to the Mariposa Grove, a grove of approximately 500 Giant Sequoia trees (Sequoia giganteum). The Park service recognizes paved surfaces and infrastructure are “compacting the soil, encroaching on sequoia roots and interfering with natural drainage patterns”. Tram service will be limited to the south entry of the park and shuttle buses would take people tot he entrance of the lower grove, where the largest and … Read More
