The Effects of Disturbance History on Ground-Layer Plant Community Composition in British Columbia

Creator:: Ton, Michael and Krawchuk, Meg A.
Abstract:: Plant communities are sensitive to perturbations and may display alternative recovery pathways depending on disturbance history. In sub-boreal lodgepole pine forests of central interior British Columbia, Canada, fire and logging are two widespread landscape disturbances that overlap in many regions. We asked whether cumulative, short-interval disturbance from logging and fire...

Using Landsat-derived disturbance history (1972–2010) to predict current forest structure

Creator:: Pflugmacher, Dirk, Cohen, Warren B., and Kennedy, Robert E.
Abstract:: Lidar is currently the most accurate method for remote estimation of forest structure, but it has limited spatial and temporal coverage. Conversely, Landsat data are more widely available, but exhibit a weaker relationship with structure under medium to high leaf area conditions. One potentially valuable means of enhancing the relationship...

Complex mountain terrain and disturbance history drive variation in forest aboveground live carbon density in the western Oregon Cascades, USA

Creator:: Zald, Harold S. J., Spies, Thomas A., Seidl, Rupert, Pabst, Robert J., Olsen, Keith A., and Steel, E. Ashley
Abstract:: Forest carbon (C) density varies tremendously across space due to the inherent heterogeneity of forest ecosystems. Variation of forest C density is especially pronounced in mountainous terrain, where environmental gradients are compressed and vary at multiple spatial scales. Additionally, the influence of environmental gradients may vary with forest age and...
