Should I remove or save my eastern hophornbeam (ironwood)?
Eastern Hophornbeam (Ironwood) isn't a habitual problem species, so a sound one is usually worth an opinion before it comes out. Nearly indestructible except for one thing: Morton rates it as not tolerant of salt, so anything within splash range of a salted road, drive, or cul-de-sac turnaround browns and thins while an identical tree 40 ft away looks perfect. It is also the most misidentified tree on any quote, because "ironwood" gets applied to both this and American hornbeam and the two routinely get billed as each other.
How to tell which one you've got
Salt scorch is the classic presentation: marginal browning and tip dieback concentrated on the road-facing side, worst in the spring following a heavy de-icing winter. Tell stress from dying at the base rather than the crown — a thin canopy that still flushes fully is stressed, while a normal-looking canopy standing over a punky, hollow-sounding butt is the tree that is actually finished.
The structural question
Forest Service silvics states its tough, resilient branches resist wind, snow, and ice damage, and it lives up to that: hophornbeam is often among the last things standing after an Indiana ice storm and rarely sheds limbs. That makes its one failure mode especially dangerous, because it is whole-tree failure from internal butt rot with no warning visible in the crown.
