Common on stressed honey locust and on trees with mower or string-trimmer damage at the base — which is a genuinely avoidable cause. In Speedway, no public street-tree inventory has been published for Speedway, so species counts are UNVERIFIED. Because the residential core finished building out by the mid-1950s and has barely been rebuilt since, much of the yard canopy is likely of comparable age and large enough to close over narrow streets and 40-to-50-foot lots — an inference from build-out dates, not a measured finding. The exception is Main Street, where a town streetscape reconstruction installed all-new landscaping, so those trees are recent. A canker that has girdled more than about half the trunk circumference is structural, not cosmetic.
Speedway's canopy and what's at risk
No public street-tree inventory has been published for Speedway, so species counts are UNVERIFIED. Because the residential core finished building out by the mid-1950s and has barely been rebuilt since, much of the yard canopy is likely of comparable age and large enough to close over narrow streets and 40-to-50-foot lots — an inference from build-out dates, not a measured finding. The exception is Main Street, where a town streetscape reconstruction installed all-new landscaping, so those trees are recent.
What to look for
Sunken dead patches on bark, sometimes oozing, often with cracked margins. Branches above the canker die back.
Whether the tree can be saved
A canker that has girdled more than about half the trunk circumference is structural, not cosmetic. Small branch cankers can be pruned out; trunk cankers usually can't.
Timing in Marion County
Prune out affected branches in dry weather, well below the canker.
