Lightning-ignitions and Santa Ana Wind-Driven Fires: Research Brief

Lightning-ignitions and Santa Ana Wind-Driven Fires: Research Brief

This paper explores whether human or natural ignition (lightning) sources are linked to wildfire occurrence during Santa Ana wind events. While lightning ignitions during Santa Ana conditions have been rare in the past, predictions under anthropogenic climate change project drier fuels during the winter months when lightning and Santa Ana winds are more likely to occur simultaneously, increasing the future potential for devastating wildfires.

Facilitating Natural Recruitment for Desert Revegetation: Research Brief

Facilitating Natural Recruitment for Desert Revegetation: Research Brief

Assisted natural regeneration (ANR) is an alternative aimed at encouraging site conditions favorable for natural regeneration through actions such as alleviating limitations on viable seed production, germination, and seedling survival. Two ANR approaches were tested on the Mojave Desert foundation species, the creosote bush.

Long-Term Change in Mojave Desert Vegetation during 37 Years of Climatic and Land-Use Dynamics: Research Brief

Long-Term Change in Mojave Desert Vegetation during 37 Years of Climatic and Land-Use Dynamics: Research Brief

A recent study in press with Ecological Monographs collected and analyzed a long-term data set of fluctuations in perennial plant communities in the eastern Mojave Desert. During the 37-year period, most measures of the native perennial plant community changed temporally.

Prioritizing planting effort and heterogeneity in reforestation: Research Brief

Prioritizing planting effort and heterogeneity in reforestation: Research Brief

In light of climatic trends, historic fire suppression, increasing incidence of large wildfires, and shrinking budgets, the authors propose a planting strategy that prioritizes accessibility, while reducing efforts within the dispersal range of seed trees and in areas with a high cost to probability-of-success ratio.

Restoration actions should consider the composition of mixed conifer forest to increase resilience in fire-excluded stands: Research Brief

 Restoration actions should consider the composition of mixed conifer forest to increase resilience in fire-excluded stands: Research Brief

In the Sierra Nevada most historical stand structure studies have focused on drier pine-dominated forests. This paper helps to fill a gap by contributing information on historical structure in more mesic forests with more moderate amounts of moisture.

Losing Southern California Sky Islands with Big Fire: Research Brief

Losing Southern California Sky Islands with Big Fire:  Research Brief

Unlike the well-studied, large conifer forests of the northern Sierra Nevada, southern California conifer forests are less-studied and represent only about 8% of the landscape. But much like the forests to the north, these valuable ecosystems are at risk of type-converting to other vegetation types.

Structure, diversity and health of Sierra Nevada red fir forests with reestablished fire regimes: Research Brief

 Structure, diversity and health of Sierra Nevada red fir forests with reestablished fire regimes: Research Brief

A 2019 study by Meyer and others showed that the reestablishment of natural fire regimes can be highly effective at restoring the structure and understory diversity of red fir forests but have little effect on the health of red fir under increasing moisture stress associated with drought and warming climate.

Acknowledging the presence of decision biases amongst emergency managers: Research Brief

Acknowledging the presence of decision biases amongst emergency managers: Research Brief

This study specifically surveyed county emergency managers; the individuals who are responsible for mitigating and responding to disaster events. The results suggest that emergency managers are subject to decision biases and by knowing this, we can improve emergency management and decision-making processes.

Treating Forests more strategically to Reduce Fire Severity and Carbon Loss: Research Brief

Treating Forests more strategically to Reduce Fire Severity and Carbon Loss: Research Brief

Locating forest treatments in the right places can make them as or more effective than treating everywhere, shows new research out by Krofcheck et al. 2018. The authors found that restoring less acres strategically can have the same impacts as treating more area indiscriminately in terms of reducing high severity wildfire risk and carbon instability.

Interval Squeeze In Action: Modeling Woody Plant Species Survival Under Three Climate Scenarios: Research Brief

Interval Squeeze In Action: Modeling Woody Plant Species Survival Under Three Climate Scenarios: Research Brief

To test the Interval Squeeze Model concept on real, fire sensitive woody species, these authors created a process-based model of a plant population that could be used for any serotinous, fire-killed species.
