Loblolly-Shortleaf Pine Forest Association
The loblolly-shortleaf pine forest association is found primarily on the Coastal Plain in Maryland. It is found on moist and poorly drained soils. At higher elevations on the Coastal Plain, it is found on drier soils and often on abandoned farmland. About 12% of Maryland's forests are loblolly-shortleaf pine. The proportion of these two species varies; however, loblolly pine usually dominates. Herbaceous plants are usually sparse because little light reaches the forest floor.
Characteristic tree species are:
Associated tree species on well-drained soils include:
Associated tree species on moister soils include:
Associated tree species in fertile, well-drained coves include:
Tree species found in the understory include:
Shrubs and vines in the understory include:
Herbaceous plants include:
Openings in the canopy from natural disturbances, such as mortality from southern pine beetles, encourage hardwood species to dominate openings. Pine reproduction rarely becomes established unless planned treatments or natural disturbances, such as severe fires, create large openings and eliminate hardwood trees in the understory. Without removal of the understory, this association will gradually convert to an oak-hickory association.
