How does a sugar maple hold up in a storm?
Better in ice than its reputation suggests — in the ISA's Urbana ice-storm survey sugar maple showed little severe damage, because its coarse, relatively low-density branching sheds ice load better than fine-twigged species. When a sugar maple does fail here it is almost always decay-driven or a split at an old codominant fork with included bark, not general brittleness, so the inspection is about unions and cavities rather than crown weight.
What pruning can and can't prevent
Late-winter cuts make it bleed sap heavily; harmless to the tree but it stains drives and alarms homeowners, so most crews here take structural work mid-to-late summer (roughly July into August) once the growth flush has hardened off. The species-specific trap is that sugar maple closes large wounds slowly and poorly — the right approach is small correctional cuts every few years, not one big reduction after twenty years of neglect, because those big cuts become decay columns.
