Overstory-derived surface fuels mediate plant species diversity in frequently burned longleaf pine forests

Publications Posted on: May 11, 2018
Frequently burned low-latitude coniferous forests maintain a high-diversity understory. Longleaf pine (Pinus palustris Mill.) forests and woodlands have exceptionally high diversity at fine scales and very frequent fire return intervals (1–3 yr). Furthermore, the positive association between high-frequency, low-intensity surface fires and high species richness in longleaf pine ecosystems is well documented but poorly understood.

Development of height-volume relationships in second growth Abies grandis for use with aerial LiDAR

Publications Posted on: January 06, 2017
Following typical forest inventory protocols, individual tree volume estimates are generally derived via diameter-at-breast-height (DBH)-based allometry. Although effective, measurement of DBH is time consuming and potentially a costly element in forest inventories.

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.

Mapping aboveground biomass annually across the northwestern USA from LiDAR and Landsat image time series

Projects Posted on: August 18, 2016
The cumulative area of LiDAR collections across multiple ownerships in the northwestern USA has reached the point that land managers of the USDA Forest Service (USFS) and other stakeholders would greatly benefit from a strategy for how to utilize LiDAR for regional aboveground biomass inventory. The need for Carbon Monitoring Systems (CMS) can be more robustly addressed by using not only available NASA satellite data products, but also commercial airborne LiDAR data collections.

How much does the time lag between wildlife field-data collection and LiDAR-data acquisition matter for studies of animal distributions? A case study using bird communities

Publications Posted on: October 03, 2014
Vegetation structure quantified by light detection and ranging (LiDAR) can improve understanding of wildlife occupancy and species-richness patterns. However, there is often a time lag between the collection of LiDAR data and wildlife data.

Status and prospects for LiDAR remote sensing of forested ecosystems

Publications Posted on: October 03, 2014
The science associated with the use of airborne and satellite Light Detection and Ranging (LiDAR) to remotely sense forest structure has rapidly progressed over the past decade.

A multiscale curvature algorithm for classifying discrete return LiDAR in forested environments

Publications Posted on: November 26, 2007
One prerequisite to the use of light detection and ranging (LiDAR) across disciplines is differentiating ground from nonground returns. The objective was to automatically and objectively classify points within unclassified LiDAR point clouds, with few model parameters and minimal postprocessing. Presented is an automated method for classifying LiDAR returns as ground or nonground in forested environments occurring in complex terrains.
