Upland forest community composition and structure by ecoregion in 73 Florida state parks – Insights for ongoing management

•Overstory, midstory, understory/regeneration and groundcover data were collected in over 37,000 nested plots from 73 Florida state parks and 15 ecoregions.•Most communities that were supposed to have pine in the overstory did.•Midstory was primarily dominated by non-pines; mainly deciduous hardwoods.•Pine seedlings and saplings were scarce.•Overstory hierarchical clustering grouped some of the similar community types within ecoregions in the same group/subgroup but midstory and regeneration clustering produced mixed results.
