Steeped in history, the majestic longleaf (Pinus palustris) is an economically and ecologically important tree species of the Atlantic and Gulf coastal plains. Its species name “palustris” means “of the marsh,” and although it is commonly associated with sandy, well drained areas, the longleaf pine is adapted to a range of soil types. Once the dominant tree on 60 million acres in the Southeastern United States, development and intense harvesting have reduced its current range to about 3 million acres. Longleaf pine are native, well-adapted, ecologically, and economically valuable trees. The longleaf’s desirable characteristics have motivated restoration efforts on timber-lands, agricultural lands, private lands, and public lands.

Longleaf Pine are Well-adapted
The more widely adapted a tree species is, the safer an investment it becomes for the future. Because the longleaf is native and adapted, it is highly resistant to most diseases and insects, such as the Southern Pine Beetle and Fusiform rust. It is perfectly adapted to, and in fact, dependent upon, a high-frequency (ideally every 1 to 3 years), low-severity surface fire regime. Its seed will germinate on the mineral soil exposed by fire. Fire also controls the understory vegetation that would otherwise compete with longleaf, preventing it from reaching its maximum growth potential, and selects for a grassland dominated habitat. The established longleaf is also quite wind resistant in comparison to other southern pines. See table 1 below.

The seedling grass-stage of longleaf is uniquely resistant to fire, and this characteristic is critical as the grass stage of longleaf can last for 1-5 years while the tree is forming its strong root system underground. The terminal bud of the grass stage is protected by a moist, dense, tuft of needles. As the tuft burns towards the bud from the needle tips, water is vaporized. The steam reflects heat away from the bud and extinguishes the fire. The bud also has scales for protection and a silver fuzzy covering that probably also reflects heat. (US Forest Service)

Longleaf Pine Provide High Quality Products
Planting longleaf is a long-term investment, but its financial viability and profitability becomes more apparent over time. It is recommended to thin four times between 20 to 45 years of age. The thinned trees themselves will provide income, while leaving the remaining trees to mature to their most valuable state. The remaining trees also act as “shelterwood” for subsequent stands. This “shelterwood” protects young seedlings. In a well-managed longleaf pine stand, future trees can be established using natural regeneration and fire, virtually eliminating repeated planting and site prep expenses. Longleaf pine produces high value timber with clear, straight wood and few defects. It was used extensively in the past for ship building, in fact, records indicate that some of the choicest stands of longleaf were set aside by the English Crown for the exclusive use of the British Navy! This pine yields a higher percentage of valuable poles than any other southern pine, and on average, poles are worth about 50% more per ton than saw-timber.
Percent poles at 39 years old:
-
Loblolly – 8%
-
Slash – 12%
-
Longleaf – 72%
Longleaf also produces valuable non-timber products such as pine straw. Longleaf pine straw is generally more desirable than other straw and commands a higher retail value. As the longleaf stand matures, more pine straw can be harvested.
Pine Straw Yields:
Age 6 – low yields
-
50 to 75 bales per acre
Age 10 – higher yields
-
between 125 to 200 bales per acre
Age 15 – maximum yield
-
200 to 300 bales per acre

Longleaf Pine are Ecologically Important
It is now recognized that a properly managed longleaf pine stand is one of the most biologically diverse habitats in North America! A wide variety of wildlife depends on the longleaf pine ecosystem. Endangered species such as red-cockaded woodpeckers and indigo snakes are threatened by the loss of longleaf pine habitat. The seeds are an excellent food source for many species. Gopher tortoises, Florida mice, gopher frogs, and eastern diamond-back rattlesnakes are among the native animals in the ecosystem.

Longleaf Pine are Part of Our Heritage
Mature longleaf forests are a uniquely beautiful sight to see. The open, park-like, vistas are visually stunning with spring and fall wildflowers. These were the southern pine forests that early settlers and pioneering botanists explored. They provided turpentine, pitch, grazing lands, valuable timber, and wildlife habitat that supported the development of the Southeastern United States. No wonder there is a growing interest among landowners, and state and federal agencies to reestablish this important and outstanding tree ecosystem.
