Distinguished by a dense midstory of shrubs with little to no canopy or groundcover layer, these communities are easily told apart by dry versus wet soils. 

Scrub (dry/xeric soils)

Scrub shrublands are composed of scrub oaks, including sand live oak (Quercus geminata), myrtle oak (Quercus myrtifolia), and Chapmannā€™s oak (Quercus chapmanii), with or without sand pine (Pinus clausa). These tree canopies are scattered between open gaps, filled with lichens and other herbaceous plants in xeric (dry) soils.

Shrub bog (wet/hydric soils)

Shrub bog shrublands are comprised of dense titi shrubs in hydric, mucky soils. They are dominated by black titi (Cliftonia monophylla) and/or titi (Cyrilla racemiflora). Shrub bogs are associated with flatwoods or along streams where soils generally stay saturated (usually <1ft deep), supplied by both precipitation and seepage.
