Bur oak is native to Indiana and is the defining tree of the state's rare bur oak savanna remnants. In central Indiana it is uncommon compared with pin oak and silver maple in older subdivisions, but it is one of the oaks most often recommended for tough urban sites here because of its alkaline soil and salt tolerance, so it shows up regularly on replacement lists where ash came out.
Bur oak is the toughest large tree you can have on a central Indiana lot — it handles alkaline soil, compacted clay, drought, and road salt better than any other oak here, which is precisely why it so rarely appears on a removal quote. When one does, it is usually a very large old tree with a construction or decay problem, or a homeowner who has finally had enough of the acorns.
