Jones Center Landscape Ecology Lab
The mission of the Jones Center Landscape Ecology Lab is to advance the science and practice of landscape ecology to inform the conservation and management of ecosystems in the Southeastern US and beyond. We achieve this by (1) conducting innovative, interdisciplinary research addressing pressing conservation challenges, (2) designing practical, evidence-based solutions that integrate ecology, community, and policy, and (3) fostering the development of skilled experts and leaders who drive positive change in conservation. We focus our efforts on three major goals:
- Understand how hurricanes and fire shape forest structure and function
- Improve conservation and management outcomes in longleaf pine forests.
- Accelerate training and adoption of new technologies for addressing conservation issues

New study: Regeneration and microclimate patterns in a structurally diverse ponderosa pine forest
Forest restoration treatments in ponderosa pine forests of the western US emphasize creation and maintenance of complex forest spatial pattern. Patterns of canopy cover and light can alter microclimate and impact seedling germination and growth. We studied fine-scale abiotic conditions and seedling dynamics for 3 years in a dry conifer forests near Denver, Colorodo. We found that canopy cover was important for mitigating extreme conditions, but that survival of all species was greatest in warm dry microclimates.
New study: Protecting planted longleaf pine from severe winds
Planted stands of longleaf pine contribute to landscape-scale restoration of the ecosystem and the imperiled species it harbors. Yet frequent severe winds from hurricanes occur throughout its range. We surveyed planted stands of longleaf pine in the aftermath of Hurricane Michael. We found that damage increased with forest fragmentation and stands with increased taper were most resistant
Now hiring: Landscape Ecology Research Technician
We are seeking applicants from motivated individuals for a Seasonal Research Technican to help with upcoming studies on disturbance ecology and restoration in longleaf pine! Applications are due April 5, 2024.
Pardon our smoke: Prescribed fire season ramps up in Georgia
February and March bring “bluebird days” where weather conditions are perfect for using prescribed fire to help conserve and protect longleaf pine ecosystems and the native species they house.
Can off-site native pines accelerate longleaf pine restoration?
Meeting the pace and scale of longleaf pine restoration may require innovative solutions. Restoration of longleaf pine woodlands often starts with removal of native pines, prior to re-establishing longleaf pine. Here, we review functional similarities among native, off-site pines such as loblolly, slash, and shortleaf have enough functional similarity. We found that native-off site species may be a useful tool for providing many of the ecological benefits especially if their retention permits unterrupted management with fire and open structure.
Pollen shedding countdown for longleaf pine
Longleaf pine pollen shedding is highly predictable based on temperature. Thanks to the diligent work of USDA Forest Service Scientist, Dr. BIll Boyer, check in daily as we track the anticipated date of peak pollen shedding in Georgia, and read about how Boyer made this discovery.
MS opportunity: Disturbance interactions and tree mortality
The Landscape Ecology lab is teaming up with Dr. Timothy Shearman from Auburn University to recruit a motivated MS student to study how repeated prescribed fire influences mortality from hurricanes. Applications are due by March 1, 2024! Classwork will be completed at Auburn and fieldwork completed at the Jones Center at Ichauway. Please share this unique opportunity widely!
New grant aims to mitigate hurricane risk to pecan orchards
In a new grant funded by the Natural Resources Conservation service, the Landscape Ecology lab will collaborate with UGA pecan expert Dr. Lenny Wells to address concerns of pecan growers state-wide. Following widespread hurricane damage in the region, this project aims to understand the major drivers of hurricane damage, and make recommendations for hurricane preparedness.
New study: Hurricanes boost reproduction in longleaf pine
Using long-term records of longleaf pine cone production, hurricane tracks, and weather data, a new study has uncovered that hurricanes can boost cone production for two years in the masting species, longleaf pine. The study was led by the Jones Center and the USDA Forest Service Southern Research Station and published in the journal New Phytologist.
New study: Patterns of hurricane gaps in a longleaf pine landscape
Ecological approaches to forestry seek to emulate aspects of natural disturbances like hurricanes which are a common disturbance in longleaf pine forets. This study used airborne lidar to measure patterns of hurricane-created gaps to offer guidance for application of natural disturbance-based management in landscapes dominated by longleaf pine.
Interview: Ichauway Forest Dynamics Plot joins as 77th site in global network
Smithsonian ForestGEO recently welcomed its 77th Forest Dynamics plot – Ichauway – in the southeastern United States. Here, they interview Principal Investigator Dr. Jeffery Cannon about the plot and how he got involved with ForestGEO.
PNAS: New study defines hurricane regimes for North American forests
Hurricanes are a chronic disturbance to many forests. but currently no study defines hurricane regimes for North America. This study uses hurricane models and long-term data to define four distinct hurricane regimes for the region, and discusses how hurricanes may be a useful lens for understanding the distribution of tree species and their traits.
New study: Predicting spatial patterns of litter fuels for fire behavior modeling
UGA graduate and Landscape Ecology lab alumnus Suzie Blaydes recently published a new article in the journal Fire Ecology. The article uses long-term data and geospatial methods to predict litter fall in longleaf pine forests. The findings will contribute to the next generation of spatilly-explicit fuel and fire models
Ichauway Forest Dynamics Plot included in global Smithsonian network
The Ichauway Forest Dynamics plot is a 40 acre research plot in a longleaf pine-oak woodland which consists of 18,000+ mapped trees over 1 cm in diameter. The new infastructure will support long-term research in longleaf pine and fire dynamics in the southeastern U.S.
Zampieri awarded SAF Mollie Beattie Scholarship
The Society of American Foresters named Dr. Nicole Zampieri among two 2023-2024 Mollie Beattie Visiting Scholars. Nicole is a post-doctoral researcher at Tall Timbers Research Station and the Jones Center at Ichauway Landscape Ecology Lab. Her current work investigates patterns of mortality in pine-oak savannas and uses dendrochronology techniques to understand patterns of disturbance. She also plays an important role in guiding and mentoring the research of fellow labmates and beyond. Congratulations, Nicole!
New study: Longleaf pine woodlands increase streamflow during droughts
Jones Center researcher Dr. Seth Younger found that longleaf pine woodlands increase water yeidl during droughts. The study looked at 21 rural watersheds with varying levels of longleaf pine cover and found that those with high longleaf pine cover had 17% higher stream flow than those with low cover. The increase was even higher during critical drought periods, highlighting how longleaf pine restoration can improve conservation outcomes on land and in streams.
Sen. Ossoff visits Ichauway, launches bill to improve data collection
Sen. Jon Ossoff visited the Jones Center at Ichauway to announce a bill that would improve data collection efforts of the US Forest Service. The new bill would authorize USFS to collect data on above and below ground carbon and adopt new technologies such as lidar. The bill is expected to improve data collection within the USFS Forest Inventory and Analysis.

New study: Longleaf pine resilience after Hurricane Michael
A new study led by University of Florida and Landscape Ecology lab alumnus Cody Pope was published in the journal Forest Ecology and Management. The study examined growth of longleaf pine and associated oak saplings for 2 years after hurricane Michael, and found that canopy removal may benefit longleaf pine over competing oak species, indicating that hurricanes may reinforce and stabilize longleaf pine dominace in frequent-fire forests.
New study: Measuring complex forests with airborne lidar
A recent study from the Landscape Ecology lab led by Andy Whelan explores a new approach to improve large-scale measurements of forest structure using lidar. The study explored the use of “volumetric pixels” (or voxels) which have shown promise for forest measurement. The technique led to accurate estimates of wood volume, even when forest composition was unknown.
