Loblolly Pine (Pinus taeda)

Loblolly Pine


A pine of the southeastern U.S., the loblolly pine is one of the most abundant trees in all of North America, owing in large part to its widespread planting for forestry.

This tentative map is based on the FHWA's ERA. This data lacks information on Canada, but also overestimates native ranges, especially around the edges, as this post explains. We have not yet reviewed or fixed this map.

Similar Plants


Adaptable to a wide range of soil types, but prefers moderately acidic soils, tolerating a pH as low as 4. Primarily found on utilsols, red clay soils, highly weathered soils common in the southeastern U.S.

Prefers poorly-drained sites, climates with 40-50 inches of rain annually, and 6-10 frost-free months. Generally found between elevations of 500-1200 ft (150-365m) and found on both flat and sloped sites.

Limited by low temperatures in the north and low rainfall in the west. Reaches slightly higher elevations in the south but still limited to under 1,200ft (365m) in elevation.

Life Cycle

Seeds germinate mostly on exposed mineral soils, such as following fire. Seeds require dormancy and germinate in March or April. Ungerminated seeds do not usually survive and there is no seed bank.

Seedlings require adequate moisture, and have some shade tolerance, and their rapid growth (2-3 feet per year) can also allow them to overtop competing vegetation. Although young plants have moderate shade tolerance, established plants are more intolerant.

Trees begin producing cones at 12-18 years of age, but seed viability is not high until age 25.

Flowering and seed production is a multi-year process, initiated in summer, followed by bud production in fall. Pollen release then occurs in spring, but timing is irregular, triggered by temperature. Cones mature September-October, with seeds released primarily in November, most falling by mid-December. Seed production is irregularly cyclical, dependent on weather conditions. High production occurs every 3-6 years, and is hindered by dry conditions in early summer or frosts at the time of flowering.

Trees over 75 years in age often develop heart rot, and are eventually killed by the southern
pine beetle. However, under good conditions trees can live up to 275 years.

Faunal Associations

This tree is eaten, and often severely damaged by the southern pine beetle (Dendroctonus frontalis), a native insect which also eats numerous other pine species.

The endangered red-cockaded woodpecker utilizes older loblolly pine trees with heart rot for its nesting. The tendency to harvest loblolly pine before 50 years of age has played a role in the decline of this woodpecker.


Loblolly pine is the most important timber species in the southeastern U.S. Its wood is valued as being hard and dense relative to other pines, and it is widely used in construction. It is widely planted in plantations.

It is sometimes also planted to stabilize soil, reclaim land damaged by mine spoil, or as a windbreak or noise barrier.

In its native range, it is planted as a landscaping plant and shade tree, where it is valued for its fast growth and tolerance of poorly-drained sites. Its survival is limited by winter cold and it does not do well much farther north than its native range.

Closely related to, and can hybridize with shortleaf pine (P. echinata), longleaf pine (P. palustris), pitch pine (P. rigida), slash pine (P. elliottii), and pond pine (P. serotina).
