Here's our newest briefs from the CFSC

Live Fuel Moisture Varies among Chaparral Species : Research Brief

The authors show how live fuel moisture content in chaparral shrub species is highly variable. This brief offers new recommendations on how to best use live fuel moisture content as a measure of fire risk.

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

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

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.

The need to restore fire regimes in protected natural areas: Research Brief

Many of California’s research natural areas exhibit high to moderate departure from their natural fire regime. Without restoration or maintenance of the natural fire regime, the ecological integrity of some natural areas could be lost.

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

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.

Private landowners in California face loss and choose to reforest after high-severity wildfire: Research Brief

This brief summarizes qualitative interviews to examine landowner responses to a reforestation program following a devastating wildfire in the central Sierra Nevada.

Mastication Fuel Treatments Impact Chaparral Structure and Biodiversity: Research Brief

The impacts of mechanical mastication fuel treatments on chaparral vegetation are discussed in this brief.
