Urban ice-storm species lists put basswood and linden on the susceptible side — the wood is soft and light, so it loads with glaze and gives way rather than flexing. The characteristic Indiana failure is not a single big limb but a split at the base of a multi-stem clump, where included bark between codominant sprout stems tears the tree open at ground level.
Prune dormant, late winter, and keep the cuts small. The species-specific trap is its sprouting reflex — a hard reduction or a topping cut answers with a fountain of epicormic shoots along the limbs and a ring of basal suckers, and because the heartwood has essentially no decay resistance, every oversized cut becomes a decay column instead of closing cleanly.
