Loblolly Pine
Arkansas’s state tree is a fast-growing southern pine whose long three-needle bundles, broad bark plates, and working-forest history shape the Coastal Plain.
Artwork inspired by Adrian Brewer
Mature loblolly pines carry dark yellow-green needles six to ten inches long, usually in bundles of three, above tall straight trunks plated with reddish-brown bark. Prickled woody cones and an irregular high crown add supporting clues. In southern Arkansas, the species dominates timberlands but also colonizes old fields and mixes naturally with hardwoods and shortleaf pine.
Identify the whole tree rather than one fallen needle. Compare several intact bundles, cone size and prickles, bark texture, crown, and site. Then read the stand: even rows and one age class signal a plantation, while varied ages, open herb cover, snags, and hardwood associates describe a different ecological and management history.
- Needles
- Usually three per bundle, six to ten inches long
- Bark
- Broad reddish-brown plates on mature trunks
- Landscape role
- Arkansas state tree and major timber species
Quick guide
- Confirm the tree
- Use several bundles, bark, cone, crown, and site
- Read the stand
- Compare plantation geometry with mixed forest structure
Identify the pine, then interpret the stand
- Count intact bundles
- Look at needles still joined at the base.
- Add bark and cones
- Compare the broad reddish-brown bark plates with any fallen woody cones.
- Rule out Shortleaf Pine
- Check multiple traits where the species overlap in Arkansas.
- Interpret management
- Read rows, spacing, age classes, understory, hardwoods, snags, and evidence of fire.
Good to know
The common name is associated with historically muddy low places, but Loblolly Pine also succeeds in old fields, managed uplands, and mixed forests. Site alone cannot confirm the identification.
Notice these
- Six-to-ten-inch needles in threes
- Broad plated reddish bark
- Prickled woody cones
- Tall bole with irregular high crown
