The Southeastern Coastal Plain Tree-Ring Laboratory
The Southeastern Coastal Plain Tree-Ring Laboratory is a collaboration between the Tall Timbers Fire Ecology Program (Monica Rother and Kevin Robertson) and Research Associate Jean Huffman. Huffman is a local expert in dendrochronology and has been working to develop tree-ring based records of fire in Florida since the late 1990s. The three researchers are working now together to uncover the fire history of several sites throughout Florida and southern Georgia, building records that will hopefully extend back into the 1600s, possibly earlier.
Very little research of this type has been conducted in our region. In the Red Hills and throughout the Southeastern Coastal Plain, this type of information has the potential to provide further justification for implementing frequent prescribed burns in the modern day.

What is dendrochronology and how can it be used to learn about past fires?
Dendrochronology is the branch of science that is focused on the analysis of tree rings. The word has its roots in Greek, with dendro meaning tree and chronology referring to the study of time. An important sub-field of dendrochronology is dendropyrochronology, or the use of tree rings to learn about previous fires (pyro meaning fire!). Scars created by past fires are used to determine how frequently and in what season fires affected a given site, and can also sometimes reveal the spatial coverage and severity of past fires. Tree-ring based fire histories are extremely valuable because they provide direct evidence of fires extending long into the past.
Archiving old wood
In addition to conducting much needed research on historic fire regimes in the Southeastern Coastal Plain, our lab also aims to serve as an archive for old wood that may be useful for future research. Old stumps contain a wealth of information about the past within their rings. Unfortunately, stumps and old trees are both rapidly disappearing in the region due to conversion of pine ecosystems to other uses (e.g. housing developments), natural decay, and the practice of stumping (deliberate removal of stumps after logging for resin), among other causes.
RED HILLS, GEORGIA: In the Red Hills Region in southern Georgia, we have begun collecting sections of fire-scarred longleaf pine (Pinus palustris) through extractions of stumps after single-tree selection harvests. We aim to uncover the fire history of a region famously associated with fire. We are actively seeking funding to move this research forward.
ST. JOSEPH BAY STATE BUFFER PRESERVE, FLORIDA: We are currently reconstructing the year and season of fires that occurred at three sites within St. Joseph Bay State Buffer Preserve, Florida. Our oldest sample that we have analyzed so far dates back into the late 1500s. Many of the samples contain dozens of fire scars.
TYNDALL AIR FORCE BASE: Our newest project is at Tyndall Air Force Base near Panama City, Florida. With local collaborators, we were able to use an excavator to extract old stumps from a flatwoods site.
