Species diversity in a longleaf pine ecosystem

Species diversity

Longleaf pine forests maintained by fire can be extraordinarily diverse—especially in their groundcover plants.

Facts summarized from The Longleaf Alliance.

A big footprint, many habitats

The Longleaf Alliance notes that longleaf pine is often thought of as a sandhill species, but historically it covered about two-thirds of the Southeast. At a landscape scale, longleaf forests occur across multiple habitat types (mountains, rolling hills, sandhills, and flatwoods).

Fire + sunlight = diversity

According to The Longleaf Alliance, a longleaf stand maintained by fire is among the most biologically diverse habitats in North America. Frequent burns help maintain open conditions and encourage a diverse ground layer of grasses, wildflowers, and legumes—fuel for fire and food for wildlife.

Wildlife examples in well-managed stands

The Longleaf Alliance gives practical examples of the kinds of wildlife that benefit from frequently burned longleaf:

  • Bobwhite quail thriving where frequent fire supports high legume populations.
  • Fox squirrels, wild turkeys, and white-tailed deer using open pine woodlands.
  • Songbirds and native butterflies associated with diverse groundcover.
  • Reptiles and amphibians—some found nowhere else—living in these habitats.
  • Longleaf pine savannas providing habitat for the endangered red-cockaded woodpecker.

If you’re restoring diversity

The diversity story is tightly linked to the ground layer. Next: Groundcover Restoration.
