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.

Natural experiment shows SPLAT fuel treatment efficacy: Research Brief

Natural experiment shows SPLAT fuel treatment efficacy: Research Brief

Strategically placed landscape area fuel treatments (SPLATs) in the Sierra Nevada were put to the test in this study when the American Fire burned through previously treated areas. Both fire effects and initial post-fire conifer regeneration were investigated.

What Type-converts Chaparral to Grassland in SoCA? Research Brief

What Type-converts Chaparral to Grassland in SoCA? Research Brief

The authors show a direct connection between a diverse set of drivers and type-converted chaparral in Southern California. Example drivers include high frequency fire, land-use disturbance, moisture availability, and site flatness.

Extreme Drought Causes Chaparral Type Conversion: Research Brief

Extreme Drought Causes Chaparral Type Conversion: Research Brief

The rugged, chaparral dominated Angeles National Forest (ANF, California) is a beautiful and popular recreation destination. However, it is being damaged by a combination of overwhelming anthropogenic stressors, including climate change-induced mega-droughts, unnaturally shortened fire intervals, very poor air quality (e.g., high levels of nitrogen deposition), and the invasion of non-native groundcover plants.

Spatial predictions of conifer regeneration after wildfire may help managers prioritize reforestation efforts: Research Brief

Spatial predictions of conifer regeneration after wildfire may help managers prioritize reforestation efforts: Research Brief

Recent work by researchers from U.C. Berkeley and the U.S. Forest Service has produced a spatially-explicit predictive model that can be used to forecast where regeneration of (non-serotinous) conifers is most likely to occur after wildfire. This predictive model combines seed availability with climatic, topographic, and burn severity data to forecast the spatial patterns of post-fire conifer regeneration
