Ecology
Pinus glabra differs markedly from most other pines in that it does not occur in largely pure pine forests, but is typically found as scattered trees in moist woodland habitats in mixed hardwood forest. To be able to compete successfully in such habitats, it has adapted to greater shade tolerance than most other pines.{{eFloras|1|233500937|Pinus glabra |family=Pinaceae |first=Robert |last=Kral}}
