Loblolly-Shortleaf Pine Forest Association
[A typical Loblolly-Shortleaf Pine Forest.] 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:
loblolly pine and shortleaf pine.

Associated tree species on well-drained soils include:
sweetgum, blackgum, southern red oak, post oak, mockernut hickory, and pignut hickory.

Associated tree species on moister soils include:
sweetgum, red maple, water oak, and willow oak.

Associated tree species in fertile, well-drained coves include:
yellow-poplar, American beech, and white ash.

Tree species found in the understory include:
southern red oak, post oak, white oak, dogwood, blackgum, persimmon, hickory, sweetgum, eastern redcedar, black oak, and blackjack oak.

Shrubs and vines in the understory include:
southern bayberry, inkberry, yaupon, mapleleaf viburnum, arrow-wood, green brier, blackberry, Virginia creeper, tree sparkleberry, low blueberry, honeysuckle, French mulberry, yellow jessamine, wild grape, witch-hazel, and sumac.

Herbaceous plants include:
uniola, panicum, sedge, and beard grass.

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.
