The forests and woodlands in the Long Island Pine Barrens are complexes of pitch pine and oak communities and interspersed wetlands. The dominant forest type, with greater than 60% canopy cover of trees, is the pitch pine-oak forest with varying proportions of pitch pine and one or more oak species (Quercus coccinea, Q. rubra, Q. alba, Q. velutina), and an understory dominated by scrub oak (Quercus ilicifolia) and ericaceous (heath) shrubs.The canopy is generally less than 2 meters (6 feet) in height and often forms a dense thicket. Almost all of the cones produced by these pine trees are of the closed cone (serotinous) type, characteristic of pineland areas experiencing frequent wildfires. Soils in this area are sandy, excessively well-drained, and nutrient-poor.
