Because it seemed many Northwood Hills residents lost entire trees or major sections of trees, NHHA member Amy Schellhorn spearheaded a project to gather data about the losses experienced. She wanted to find out if some species of trees were more likely to uproot or lose large branches and which ones fared the best. NHHA members were invited to participate in a survey to share details about the damage they experienced and the trees that stayed strong.

Seventy-five households were represented in the survey and of those, twenty-two reported uprooted trees. Oaks (unspecified) made up the majority of trees lost, with crepe myrtles coming in second. Almost 80% of respondents reported the loss of large limbs (greater than 1 foot in diameter). Red Oaks, Live Oaks, and Cedar Elms were the biggest offenders in this category. Some households reported minimal to no damage on some of their trees, with most mentioning Live Oaks and Crepe Myrtles in their responses. Respondents attributed regular pruning and the specific location of the tree (i.e. if it was shielded from high winds by a house or other tree) as the reason for minimized damage. The full data, along with recommendations, is shown below:

5) Observations/comments from respondents:

          Seven people commented that they believed the regular pruning seemed to have helped minimize damage in their trees. In a few cases, people commented that their tree that was severely damaged was sick and in a weakened condition. One person commented that pecan trees are brittle, and was grateful there were no injuries; others commented how sad it is for the neighborhood to have sustained so much damage.

        There were several comments on how well the city completed the cleanup, along with advice to stack the debris high and away from the mailbox. Another person noted that trees that received direct impact from the wind were the most damaged. The trees that were somewhat shielded, either by other trees or the house, did not suffer damage. Multi-trunked trees often sustained more damage in these winds.

Amy visited with arborist Alan Johnson of Holcomb Trees to get advice for Northwood Hills’ residents. Alan recommends pruning trees every 2 years, or 3 years in cases of drought when trees aren’t growing as much. In his observations, he noted Cedar Elms and Pecans sustaining the most damage, with the largest Red Oaks more likely to be uprooted. If you’re looking to plant this Fall (the best time to do so), Alan recommends White Oaks, like a Bur Oak or a Chinkapin Oak. They are less susceptible to oak wilt than Red Oaks or Live Oaks. If you’re looking for a faster growing tree, consider Cedar Elm, Sweet Gum, or Texas Ash, but be warned they have softer wood and would be more susceptible to wind damage.

Even though Oak trees experienced significant damage from this unusual storm, it’s important to remember they are typically strong trees with a 200 – 300 year life span. Pecan trees can also live for hundreds of years, but they are known to be more brittle and are “self-pruning.” The magnificent trees in Northwood Hills add value to our properties and enrich our neighborhood, so if you were left with a large void after the storm, consider Alan’s advice, visit a tree farm, and also be on the lookout for a City of Dallas tree giveaway program this fall. Thanks to the survey respondents, our researcher Amy Schellhorn, and arborist Alan Johnson for their contributions to this project.

The City will only be collecting storm debris in July. Storm debris includes tree limbs, brush, and property damage. Try to separate the tree limbs and green debris from other items. DO NOT put out large debris, such as furniture, appliances, or other bulky items. Normal bulk and brush pick-up will resume in August.
