Every year, starting in late June I see limb failures that appear to be caused by a fungus developing a pressure pad directly in the inner fibers of the wood. The pressure from this growth causes the wood to shear and the limb fails.
As a business practice, we have always recycled all debris via local brush recycling company. However, with the purchase of a tub grinder, now we recycle our own brush. Recycling our brush in house will allow us to offer more competitive pricing for our services that require mulch. And we’ll get better quality control over the mulch product. (keep reading…)
Do you know about the City of Austin’s Urban Forestry Board? The primary purpose of the board is to provide the citizens of Austin a portal to voice their concerns about policies and practices regarding the city’s public trees. (keep reading…)
Assessing tree risk is one of the more complex functions certified arborists must perform. The simple fact is that tree failures are, in large part, unpredictable. To help our profession, the International Society of Arboriculture (ISA) has developed some standards to the process of evaluating tree risk and there is now a “qualification” for arborists to acquire. Being the inquisitive individual that I am, I’ve attended the class and passed the test to become TRAQ qualified. (keep reading…)
For many years, the arborist community has been touting the great benefits trees offer to the urban environment. I think everybody in the world agrees with this from the surface level. One of the deeper discussions on this topic is the value of stormwater-runoff mitigation that trees can provide. However, nearly every time I’ve tried to bring up this topic in a planning (keep reading…)
The city of Austin heritage tree ordinance was adopted back in February of 2010. The new ordinance expands upon the existing tree protection ordinance creating a new “class” of protected size tree. (keep reading…)
Just today, one of my respected colleagues, Heather Brewer, a municipal forester in the City of Georgetown, turned me on to a bill that is being introduced by Republican house member Lois Kolkhorst. Kolkhorst is from Brenham, TX. Her proposal aims to put maximum limits on tree mitigation that a government entity can require. And, the proposal prevents a municipality from enforcing tree protection in extra-territorial jurisdictions. As much as we all hate complicated law, there is a need for it. Expecting us to all get along without rules is overly optimistic. So, I do think some variety of state regulation could be useful if the language is well written. However, this proposal raises an eyebrow on me for many reasons. (keep reading…)
The purpose of the mulch calculator is to help you figure out how much mulch you need to buy for your mulching project. Mulch is conventionally sold by the yard. When you draw an area on the map it tells you how many yards of mulch are required to cover the area and also gives you some square footage calculations in case that is useful to you. There are some price calculations in there, but it’s really up to you to price shop and get the best deal you can.
There are so many different fungi out there. Only some of them affect trees. Some grow on/in trees, but don’t really affect the tree’s health. Some usually don’t affect tree health, but can become pathogenic in the right circumstances. Identifying and understanding all these different fungi is definitely one of the more challenging parts of being an arborist. Over the years, I have run into a number of these fungi and done some homework on them. However, many of these fungi are pretty uncommon so retaining all the details I learn about a fungus I only see once in a while becomes an issue sometimes. To help with the challenges of identifying fungi, I made this Fungus photo identification helper tool. I’ve only recently created it, so there are a lot of fungi that I haven’t yet added to the list. But, it will grow with time as I use it. I hope you find it helpful. Watch this short video to see how it works.
On October 5th – 7th the best arborists in the state will be meeting in Waco for the 32nd annual Texas Tree Conference. The event is for local arborists and foresters to learn from the leading researches and leaders in the industry and obtain needed CEU’s to maintain arborist certification requirements. However, anybody is welcome. You don’t have to be a professional arborist to come.
