Estimating the leaf area index of north central Wisconsin forests using the Landsat Thematic Mapper

KS Fassnacht, ST Gower, MD MacKenzie… - Remote sensing of …, 1997 - Elsevier
Leaf area index (LAI) is an extremely important structural characteristic of vegetation because
it is directly related to the exchange of energy, CO 2 and mass from plant canopies at a …

Wildfire and charcoal enhance nitrification and ammonium‐oxidizing bacterial abundance in dry montane forest soils

PN Ball, MD MacKenzie, TH DeLuca… - Journal of …, 2010 - Wiley Online Library
All forest fire events generate some quantity of charcoal, which may persist in soils for hundreds
