Pinus echinata Shortleaf pine grows naturally in the mountains, piedmont, and upper coastal plain. It reaches an average height of 80-100 feet and 2-3 feet in diameter. It has a clear, well-formed bole, and a small narrowly pyramidal crown. It is generally found on dry upland soils which are neither highly acidic nor strongly alkaline. The species may be less tolerant than loblolly pine, but young trees will endure suppression for many years and yet respond quickly to release. Shortleaf pine is considered slower growing than the other southern pines, and is generally disfavored where other pines are well adapted. It is the most common species regenerated in the northern and western parts of its range and is a valuable timber and pulp species. Shortleaf pine seeds are eaten by squirrels and birds and very mature trees with red heart disease are favored nesting sites for the red-cockaded woodpecker.
