Just came across this monster red oak next to an abandoned mansion in Trenton. Over 6 feet in diameter (19 ft in circumference). Not big enough to be NJ state champ, but would be pretty high on the NJ big tree database. May have to submit!

But this one is a bit more unusual, as the girdling root is from a completely different tree.

One common defect in urban trees are stem-girdling roots, where, rather than growing outwards, a root will wrap around its own trunk, limiting growth and nutrient flow, and eventually destabilizing the entire tree.

Street trees make good neighborhoods great

I’m working on a street tree inventory and have mapped hundreds of ashes dying due to EAB infestation. Every once in a while I find one that’s so far completely unaffected, like the one on the left.

Really appreciate the program in Trenton that offers small children the opportunity to rename city streets

Out working on a tree inventory on one of the hottest days of the summer so far, and the value of shade for people moving around Trenton on a day like this can not be overstated.

I called my Congressperson about it (replacement-level Dem, Donald Norcross), and the letter his office sent me back noted that the arrest “raises concerns” about the 1A then spends a lot of time condemning violent and intimidating rhetoric, which Khalil has never credibly been accused of!

I don’t see how the weight and speed of the pedestrians is relevant to keeping this park safe.

You’re channeling Harry Zimm from ‘Get Shorty’

Looking forward to being empaneled as a juror at his future trial.
