The longleaf pine (Pinus palustris) is the state tree of Alabama. It is a tall evergreen with very long needles and large cones, and it once formed vast open forests across the coastal plain of the Southeast. The tree is closely tied to fire, which clears competing plants and helps its seedlings grow. Alabama named the southern pine its state tree in 1949, and a later act specified the longleaf pine [1][2]. This article covers the tree’s biology, its role as an ecosystem and the efforts to restore it.

What is a longleaf pine?
The longleaf pine is a native pine of the southeastern United States. Its needles, which grow in bundles of three, are among the longest of any North American pine, and its cones are among the largest. Mature trees can reach about 100 feet in height, and some live for several centuries. The wood is strong and resinous, which made it valuable for timber and for products called naval stores, such as turpentine and tar [2].
The grass stage
Young longleaf pines pass through an unusual phase known as the grass stage. For several years the seedling looks like a clump of grass, with a thick tuft of needles protecting a bud close to the ground. During this period the plant builds a deep root system. When fires sweep through, the dense needles shield the bud, and the seedling survives. After the stage ends, the tree grows rapidly upward, lifting its bud above the reach of ground fires [2].
A fire-dependent ecosystem
Longleaf forests were maintained by frequent, low-intensity fires that burned through the grassy ground cover every few years. These fires cleared brush, recycled nutrients and kept the forest open. The open structure allowed sunlight to reach the ground, supporting a rich mix of wildflowers and grasses. Many plants that live there are found almost nowhere else, which makes the ecosystem a hotspot for biodiversity [1][2].
Wildlife
Animals that depend on longleaf forests include the red-cockaded woodpecker, the gopher tortoise and the eastern indigo snake. The gopher tortoise digs burrows that shelter many other species. Birds such as the Bachman’s sparrow and the brown-headed nuthatch also favor the open pine woods. Protecting longleaf habitat therefore protects an entire community of living things [2].
Decline and restoration
Longleaf forests once covered tens of millions of acres across the South. Logging, turpentine production, clearing for farms and the suppression of fire reduced them to a small fraction of their former extent. Today landowners, conservation groups and public agencies are replanting longleaf pines and restoring prescribed burning. Alabama has several protected longleaf areas, including parts of the national forests and state lands [1][2].
A state tree
The legislature first named the southern pine the state tree in 1949, and a later act clarified that the tree was the longleaf pine. The tree appears in the Alabama emblems described in Alabama State Symbols, together with the flower in Camellia (Alabama State Flower). Readers interested in the forest’s role in the wider landscape can continue to the main Alabama profile [1][2].
