A positive case of oak wilt, a destructive tree disease, has been reported in the city of Arlington. The affected tree was found in west Arlington, within the 76017 area code, according to Wendy Pappas, the urban forest and land manager for the city.

Oak Wilt Disease

Oak wilt is an infectious disease caused by a fungus that can quickly kill a tree by preventing it from effectively processing water. Demian Gomez, a regional health coordinator for the Texas A&M Forestry Service, explained that the disease spreads through open wounds on trees, which can be exacerbated by trimming or pruning, as well as through the root systems of nearby trees.

Gomez emphasized that every oak tree in Texas is susceptible to the disease, and it is crucial for homeowners to be aware of the potential impact on their property. Pappas noted that the city has adjusted its contract with third-party landscaping companies to help combat the spread of the disease, requiring them to use an approved sealing spray paint on open tree wounds after pruning.

To prevent the spread of oak wilt, officials recommend that homeowners educate themselves about the types of trees they have and how the disease manifests in those species. Additional tips for spotting or preventing the spread of oak wilt can be found at TexasOakWilt.org.
