Initial Assessment of Canopy Fuel Factors in Forested Areas of the Netherlands
… fire behavior in that country. Leaf area index, gap fraction, and canopy bulk density were estimated using hemispherical photography, LI-COR LAI 2200c Plant Canopy Analyzer, spherical densiometer and allometeric methods. The crown allometry data collected was species, density (trees per ha), …

The Influence of Overstory Structure on Understory Light Availability in a Longleaf Pine (Pinus palustris Mill.) Forest
… used to estimate weighted canopy openness and gap fraction were effective methods, but gap light index (GLI) also derived from hemispherical photographs performed better. Accuracy of daily %PPFD estimates using %PPFDovercast, weighted canopy openness, and gap fraction were strongly affected by …

Forest Net Primary Production Resistance Across a Gradient of Moderate Disturbance
… upper canopy tree basal area. As upper canopy gap fraction increased with rising disturbance severity, greater light availability to the subcanopy enhanced leaf-level C uptake and the growth of this formerly light-limited canopy stratum, compensating for upper canopy production losses. As a …

Effects of Climate, Forest Structure, Soil Water, & Scale on Biosphere-Atmosphere Gas Exchange in a Great Lakes Mixed-Deciduous Forest
… first described a data processing, analysis, and gap-filling package for the AmeriFlux-affiliated meteorological stations at UMBS. This data package was then utilized to test the sensitivity of carbon fluxes to climate from 2000-12. We found carbon dynamics to be significantly affected by …
