P. taeda is a perennial tree of the Pinaceae family native to North America.
P. taeda is found in the southeastern corner of the United States excluding Indiana and West Virginia.
P. taeda proliferates in forests, fields, and pine plantations. Specimens have been collected from palm hammock ear edge of river, open pine woodland, small old field, mesic coastal palm oak hammock, loamy soil near small pond, palmetto flatwoods, open pasture, mixed hardwoods, and pine flatwoods.
P. taeda became absent in response to military training in west Georgia longleaf pine forests. It has shown resistance to regrowth in reestablished pine forests that were disturbed by this activity.
Pinus taeda is frequent and abundant in the Peninsula Xeric Sandhills, North Florida Longleaf Woodlands, North Florida Subxeric Sandhills, Clayhill Longleaf Woodlands, and Upper Panhandle Savannas community types as described in Carr et al. (2010).
P. taeda has been observed flowering in March.
This species is thought to be dispersed by wind.
Seed bank and germination
Seeds of P. taeda have low viability after one year.
Herbivory and toxicology
Pinus taeda has been observed to host leafcutting bees such as Spissistilus festinus (family Membracidae), swallowtail butterflys such as Graphium sp. (family Papilionidae), aphids from the Aphididae family such as Cinara sp. and Uroleucon sp., assassin bugs from the Reduviidae family such as Apiomerus crassipes, Rhynocoris sp. and Zelus tetracanthus, and plant bugs from the Miridae family such as Phoenicocoris claricornis and Pilophorus laetus.
Conservation, cultivation, and restoration
P. taeda is listed as a weedy or invasive species by the Hawaiian Ecosystems at Risk Project Biological Resources Division. This species should avoid soil disturbance by military training to conserve its presence in pine communities.
Tar from these trees can be used as inhalants for treating pulmonary diseases. Salves and oils could be used for acne and skin diseases, intestinal worms, as a stimulant, and as a laxative.
