The outsized role of California’s largest wildfires in changing forest burn patterns and coarsening ecosystem scale

Year of Publication
2023
Publication Type
Highlights • We evaluated trends for 1,809 fires that burned 1985–2020 across California forests. • Top 1% of fires by size burned 47% of total area burned across the study period. • Top 1% (18 fires) produced 58% of high and 42% of low-moderate severity area. • Top 1% created novel landscape patterns of large burn severity patches.

Review of broad-scale drought monitoring of forests: Toward an integrated data mining approach

Year of Publication
2016
Publication Type
Efforts to monitor the broad-scale impacts of drought on forests often come up short. Drought is a direct stressor of forests as well as a driver of secondary disturbance agents, making a full accounting of drought impacts challenging. General impacts can be inferred from moisture deficits quantified using precipitation and temperature measurements.

Integrating Theoretical Climate and Fire Effects on Savanna and Forest Systems

Year of Publication
2012
Publication Type
The role of fire and climate in determining savanna and forest distributions requires comprehensive theoretical reevaluation. Empirical studies show that climate constrains maximum tree cover and that fire feedbacks can reduce tree cover substantially, but neither the stability nor the dynamics of these systems are well understood.

Seasonal variation in surface fuel moisture between unthinned and thinned mixed conifer forest, northern California, USA

Year of Publication
2012
Publication Type
Reducing stand density is often used as a tool for mitigating the risk of high-intensity crown fires. However, concern has been expressed that opening stands might lead to greater drying of surface fuels, contributing to increased fire risk. The objective of this study was to determine whether woody fuel moisture differed between unthinned and thinned mixed-conifer stands.

Shrub Seed Banks in Mixed Conifer Forests of Northern California and the Role of Fire in Regulating Abundance

Year of Publication
2012
Publication Type
Understory shrubs play important ecological roles in forests of the western US, but they can also impede early tree growth and lead to fire hazard concerns when very dense. Some of the more common genera (Ceanothus, Arctostaphylos, and Prunus) persist for long periods in the seed bank, even in areas where plants have been shaded out.
