Small-scale Duff Burning and Mechanisms of Overstory Pine Decline and Mortality - Weather conditions and forest floor consumption data for 4 burn treatments (OrdwayIndivTreeBurn.xls)
Content Description
Abstract:
Post-fire mortality, whether resulting from prescribed burns or wildfires, is an issue of great interest to researchers and resource managers in fire-prone ecosystems worldwide. Amount of mortality is easily quantified, causes of mortality less so, and mechanisms of mortality even more difficult. In long-unburned pine forests, four primary hypotheses related to fire-caused conifer mortality have been proposed:
(1) smoldering Oe and Oa horizons damage vascular tissues of the stem base;
(2) smoldering Oe and Oa horizons damage roots in the organic and surficial mineral soil horizons;
(3) associated flaming combustion damages canopy meristems; and
(4) fire-caused damage and subsequent stresses lead to whole-tree carbohydrate deficits.
Beginning in the fall of 2003, we used overstory longleaf pines to evaluate three of these hypotheses using small-scale fire damage and fire surrogates (mechanical damage to tissues) to test these hypotheses (root, stem, root stem).
Purpose:
Study: Small-scale Duff Burning and Mechanisms of Overstory Pine Decline and Mortality
(mortality and radial growth surveys on-going)
"Burn Day Data" provides weather conditions under which "Tree Data-Forest Floor consumption data for 4 burning treatments " was collected as part of a Small-scale Duff Burning and Overstory Pine Decline Study under the 01-1-3-11 Duff Consumption and Southern Pine Mortality (JFSP) project {4DAA8684-ED0E-4D38-B2B6-32374E6CF0E0}.
