LBA-ECO Synthesis: Forest Disturbance Leaders: Jeff Chambers, Niro Higuchi Topics: –Regional tree mortality evaluation –Remote sensing methods for disturbance –Modeling the consequences of disturbance Workshops: –June 2006, May 2007 Products: –Not yet defined
6
Tree Mortality Probability Distribution Function What is the spatial dimension to mortality events? The temporal and spatial distribution of mortality events at the landscape scale can have important control over regional carbon balance. What is the frequency of catastrophic events?

Disturbance Effects on Carbon Dynamics in Amazon Forest: A Synthesis from Individual Trees to Landscapes Workshop 1 – Tulane University, New Orleans, Late June 2006 –(i) developing a consistent basin wide dataset of tree mortality dynamics from inventory plot data –(ii) exploring different remote sensing methods for detecting intermediate-scale (~0.1 to 5 ha) canopy gaps – e.g. blowdowns, selective logging. –(iii) comparing modeling approaches of forest response to gap disturbance Workshop 2 – Tulane University, New Orleans, Late May 2007 –(i) exploring a general forest response framework across the natural to anthropogenic disturbance gradient –(ii) comparing various remote sensing methods for detecting a range of disturbance types and processes –(iii) evaluating modeling approaches for simulating this disturbance gradient
