Summer Annual Prescribed Burn

Overview

Objectives

Demonstrates the effects of annual prescribed fire during the summer (approximately May-July), on the understory and regeneration of a flatwoods site.

The study area is adjacent to a flatwoods forests burned on 2- and 3-year intervals. It provides a striking visual contrast on how these burn intervals affect understory species composition.

Summary / Lessons Learned / Additional Thoughts

The study listed below used this site and focused on how annual prescribed burning affects understory species, primarily wiregrass.

Stand Information Pretreatment

Land Use History

Likely selectively logged, turpentined, and grazed before University acquisition in 1936. When the study was established in 1978, it was initially burned in the dormant season until 2001, when it was transitioned into the current annual summer burn regime.

Stand Area

7 Acres

Stand Age Before Treatment

43 Years Old

Pretreatment Overstory Community Composition

Mixed longleaf (Pinus palustris) and slash (P. elliotti) pine.

Pretreatment Forest Metrics

Total Basal Area

93.82 Feet Squared per Acre

Species Composition

Information not provided.

Soil Series

Primarily Pomona sand, which is a deep, poorly drained sandy soil typical of flatwoods. 0 to 2 percent slopes. 25 to 89 centimeters to spodic horizon.

Silvicultural Application(s) Used in Study

Are there any local forest health threats to your target species?

No

Notes on silvicultural process(es) or data collection?

This stand has been the site of numerous individual studies that focus on different areas of the ecosystem, e.g. wiregrass populations, pollinator populations, saw palmetto fruiting, understory biodiversity, etc.

Plans for Future Treatments

UF plans to continue burning this stand on an annual basis in the growing season.

Plans for Future Measurements

Costs and Economic Considerations

Not definitively tracked but the cost of prescribed fire at a site with low fuel loads and extensive and well-maintained fire breaks is generally lower than average for the region.
