Simulating groundcover community assembly in a frequently burned ecosystem using a simple neutral model

Publications Posted on: September 14, 2019
Fire is a keystone process that drives patterns of biodiversity globally. In frequently burned fire-dependent ecosystems, surface fire regimes allow for the coexistence of high plant diversity at fine scales even where soils are uniform. The mechanisms on how fire impacts groundcover community dynamics are, however, poorly understood.

Using forest inventory data with Landsat 8 imagery to map longleaf pine forest characteristics in Georgia, USA

Publications Posted on: August 19, 2019
This study improved on previous efforts to map longleaf pine (Pinus palustris) over large areas in the southeastern United States of America by developing new methods that integrate forest inventory data, aerial photography and Landsat 8 imagery to model forest characteristics.

The big picture: New perspectives on restoring landscapes

Documents and Media Posted on: August 06, 2019
Faced with limited funds and resources, how do land and resource managers prioritize restoration efforts that cover millions of acres of public and private land? It’s a question that’s been asked repeatedly in the southeastern United States, where the U.S. Forest Service and its partners have committed to restoring millions of acres of longleaf pine ecosystems. These ecosystems, which are home to dozens of species of conservation concern, cover less than 5 percent of their historic range. Document Type: Other Documents

Inferring energy incident on sensors in low-intensity surface fires from remotely sensed radiation and using it to predict tree stem injury

Publications Posted on: April 09, 2019
Remotely sensed radiation, attractive for its spatial and temporal coverage, offers a means of inferring energy deposition in fires (e.g. on soils, fuels and tree stems) but coordinated remote and in situ (in-flame) measurements are lacking.

Maximizing the monitoring of diversity for management activities: Additive partitioning of plant species diversity across a frequently burned ecosystem

Publications Posted on: October 03, 2018
Monitoring understory plant diversity is important, allowing managers to track current diversity status and trends both spatially and temporally at a landscape-scale. Improving precision in quantifying patterns in understory plant diversity improves efficiency in monitoring design and more accurate measures of success of management intervention over time.

High-tech help for longleaf pine mapping

Projects Posted on: May 09, 2017
Longleaf pine forests are one of the most critically endangered ecosystems in the world. RMRS scientists and collaborators have developed new tools that can quantify the amount and condition of longleaf pine forest at fine spatial resolution over large areas. Researchers are improving the technologies and software and strengthening the extension and outreach aspects of this work. The next phase of the project will run through 2020.

Imputation of individual longleaf pine (Pinus palustris Mill.) tree attributes from field and LiDAR data

Publications Posted on: September 15, 2016
Light Detection and Ranging (LiDAR) has demonstrated potential for forest inventory at the individual-tree level.

Mapping forest structure and composition from low-density LiDAR for informed forest, fuel, and fire management at Eglin Air Force Base, Florida, USA

Publications Posted on: September 14, 2016
Eglin Air Force Base (AFB) in Florida, in the United States, conserves a large reservoir of native longleaf pine (Pinus palustris Mill.) stands that land managers maintain by using frequent fires. We predicted tree density, basal area, and dominant tree species from 195 forest inventory plots, low-density airborne LiDAR, and Landsat data available across the entirety of Eglin AFB.

Canopy-derived fuels drive patterns of in-fire energy release and understory plant mortality in a longleaf pine ( Pinus palustris ) sandhill in northwest Florida, USA

Publications Posted on: September 14, 2016
Wildland fire radiant energy emission is one of the only measurements of combustion that can be made at high temporal and spatial resolutions. Furthermore, spatially and temporally explicit measurements are critical for making inferences about ecological fire effects.

Forest structure relates to plant diversity, fuels, and fire regime

Science Spotlights Posted on: August 18, 2016
Forest, fuel, and fire management strategies and decisions applied at the scale of forest stands influence not just the tree overstory but also understory plant composition and structure. Understory plants and forest floor materials constitute the surface fuels burned in prescribed fires. Researchers associated LiDAR data from Eglin Air Force Base in Florida with field plot data and fire management records.
