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.
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.
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.
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.
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.
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.
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.
This brief summarizes qualitative interviews to examine landowner responses to a reforestation program following a devastating wildfire in the central Sierra Nevada.
The impacts of mechanical mastication fuel treatments on chaparral vegetation are discussed in this brief.
