Tree Appraisal Outlook

August 14, 2014

How much is a tree worth? In dollars, I’m not talking about the sentimental value (that’s impossible to calculate). Performing a tree appraisal to assign a dollar value to trees in some ways is straight forward; in other ways, it is very complex. I’ve been involved in a number of projects where I’m appraising the value of trees. Almost every time, somebody is trying to tell me how I should be valuing the tree. (keep reading…)


Hypoxylon Canker

August 6, 2014

By far, the most prevalent tree disease I encounter is Hypoxylon canker. It affects nearly every species of tree native in our area. The disease typically targets stressed trees during drought conditions, so you can imagine how central Texas is a great niche for this sapwood fungal disease. (keep reading…)


Summer Limb Drop

July 17, 2014

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.

Tub Grinder Brush Recycling (Mulching) Service

July 2, 2014

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…)


Keith Brown Appointed to Urban Forestry Board

June 26, 2014

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…)


ISA Tree Risk Assessment Qualification (TRAQ)

January 1, 2014

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…)


Using Trees for Stormwater Runoff Mitigation

September 27, 2013

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…)


Heritage Tree Ordinanace in Austin

August 31, 2013

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…)


Kolkhorst Anti Tree Bill

February 23, 2013

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…)


Mulch Calculator

November 19, 2011

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.
