High Pine

a typical overstory of longleaf pine, photo by Julie Anne Ferguson DemersHigh pine is an upland savanna-like ecosystem typified by an open overstory of Pinus palustris (longleaf pine) and a ground cover of perennial grasses (primarily wiregrass) and forbs interspersed with oaks. High pine ecosystems once encompassed the following community types: sandhill, clayhill, longleaf pine/turkey oak barrens, and upland pine forests.

In an old-growth longleaf pine-wiregrass habitat, trees account for less than 2% of the plant species richness. More than 98% of the plants in this habitat (>400) rarely grow taller than knee-height.

Visit our Other Forest Values page in the Forest Management section for information about restoring longleaf pine sandhill communities.

Vegetation

There are several variations of the sandhill ecosystem. Where fire is excluded and/or the pines have been removed, oaks dominate. Ground cover under trees and shrubs is scattered and sometimes absent.

  • longleaf pine (Pinus palustris)

Of the 25 million hectares of longleaf pine forests that existed in the coastal plain before European settlement, about 3% of the uplands support high pine vegetation today.

  • an interim stage of development between the seedling and sapling stages known as the grass stage, which gives the tree additional protection from fire;
  • a terminal bud that remains near ground level for several years, sometimes a decade or more;
  • needles that are dense, long and moisture-laden.

Hardwoods:

Today, because of changes in fire regimes that followed the exploitation of longleaf pine, most sandhills are dominated by Quercus laevis (turkey oak). Other hardwoods commonly found on sandhills include:

  • bluejack oak (Quercus incana) may be dominant with turkey oak
  • southern red oak or Spanish oak (Q. falcata) on more mesic, fertile sites
  • blackjack oak (Q. marilandica) in the panhandle
  • sand post oak (Q. stellata var. margaretta)
  • live oak (Q. virginiana)
  • Arkansas oak (Q. arkansana)
  • persimmon(Diospyros virginiana)
  • black cherry (Prunus serotina)
  • sassafras (Sassafras albidum)
  • mockernut hickory (Carya tomentosa)
  • sand hickory (Carya pullida)

Shrubs:

  • sparkleberry (Vaccinium arboreum)
  • pawpaw (Asimina incarna)
  • myrtle oak (Quercus myrtifolia) and other evergreen oaks

  • wiregrass (Aristida stricta)
  • bluestems (Andropogon spp.)
  • piney woods dropseed (Sporobolus junceus)

  • golden aster (Pityopsis graminifolia)
  • low-bush blueberry (Vaccinium myrsinities)
  • blackberry (Rubus cuneifolius)
  • hairawn muhly (Muhlenbergia capillaris)

Fauna

red-cockaded woodpecker, Fort Bragg, US ArmyHigh pine supports many vertebrates found in a number of Florida's habitats. A minority of these, however, depend on these dry upland habitats for survival. A few of those are introduced here.

The Picoides borealis (red cockaded woodpecker (RCW)) is a federally-listed endangered species which epitomizes old-growth longleaf pine forests of both highlands and flatwoods. This bird is at the center of controversy over the management of public forests because:

  • the RCW nests in cavities of large old pines - this habitat is nearly decimated with the demise of longleaf pine forests.

Other fauna which typify high pine habitats include:
