The article came out today, feels pretty surreal to be in the paper! Really good article that lays out the challenges ahead here.
Damage to trees in western North Carolina from Hurricane Helene was ‘extraordinary and humbling’ but urban areas face particular problems

I also posted a reel for the masses with some of my findings on Ig. This is the description:
“I conducted an initial survey of tree failures from Helene which I documented in a previous reel. A lot of folks asked what the general species composition of trees in the area was, so I took a control survey so we could see if some trees really did better than others.
-Much more likely to fail: Red oak group, White oak group, Hickory, Sourwood.
-Somewhat more likely to fail: Pine, Norway spruce, Black cherry, Black locust.
-Somewhat less likely to fail: Hemlock, Sycamore, Black walnut.
-Much less likely to fail: Maple, Tuliptree (aka Poplar).
-An increase in diameter essentially correlates with an increase in likelihood of failure.
Heavily saturated soils and tropical storm force winds are always going to lead to tree damage, but Western North Carolina has no record of such extensive tree damage as this. Buncombe County lost 17% of our forests, Mitchell County 48%, so this is a truly enormous quantity of downed trees.
Some working theories for why maples and Tuliptrees did so well – they had less drag, having shed some leaves prior to the storm. They’re also more deeply rooted and have less mass. Oaks and hickories are extremely heavy. White pines have become the dominant pine species in our forests (14%) but only 60 years ago were not that common at all – Shortleaf pine is a better bet. Norway spruce is introduced.
While this was a very rare storm, changes in climate will continue to drive these abnormally extreme storms (you can blame geoengineering, let’s agree it’s human driven). Large oak trees should be professionally assessed in the landscape, even if they’re defect free. Tip weight reduction can reduce their likelihood of failure. For younger trees, thin competition and leave low limbs to increase taper and keep center of gravity low. Plant a diversity of native trees in the right places with plenty of room to grow. And care for the trees you have.
I’m writing a research paper on this data with Jenna Rindy that will be published shortly.”
