Should I remove or save my river birch?
River Birch isn't a habitual problem species, so a sound one is usually worth an opinion before it comes out. River birch is the default subdivision tree in central Indiana, planted by the thousand as a three-stem clump because it is the one birch that genuinely resists bronze birch borer. The calls it generates are not hazard calls — they are "why is it yellow," "why is it dropping leaves in July," and "the ice folded it over and it never stood back up."
How to tell which one you've got
The signature problem here is iron chlorosis — leaves turn chartreuse or yellow with darker green veins, worst on new growth at the top — because river birch wants acid soil and central Indiana's glacial clay typically runs neutral to alkaline. Stress is normal summer leaf drop in a dry August, which a mature river birch does routinely and recovers from; dying is thin, sparse crowns with dead twiggy tips at the top over consecutive seasons and chlorosis that deepens each year, since twig and branch dieback is chronic in this species and the dead parts shed readily.
The structural question
River birch is supple and bends a long way under ice rather than snapping, but bending is the failure mode — fine twigs and dense tops load with glaze and clump stems fold to the ground, and many never stand back up. That turns into a reduce-or-remove decision rather than a broken-limb cleanup, and because birch decays fast, trying to salvage a folded stem usually costs more than it returns.
