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.

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.

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.

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.

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

Using historical forest density estimates to inform management of contemporary Sierra Nevada forests: Research Brief

 Using historical forest density estimates to inform management of contemporary Sierra Nevada forests: Research Brief

This brief discusses and compares the two methods used to estimate historic tree densities of the Sierra Nevada. The study suggests that density estimates from distance-based estimators support the historical density estimates derived from timber inventories and reconstructions.

How to Protect Old Trees When Reintroducing Fire: Research Brief

How to Protect Old Trees When Reintroducing Fire: Research Brief

This brief is based on a synthesis that covers recent research documenting effects of introducing fire in fire suppressed forests, provides necessary background information to understand the breadth of the problem, provides realistic management solutions to reduce impacts and defines monitoring techniques to identify treatment effects.

How can managers consider bumble bees during post-fire management? Research Brief

How can managers consider bumble bees during post-fire management? Research Brief

Bumble bees are important pollinators of native plant species. This brief provides information that can support managers in making nuanced decisions to benefit bumble bees during post-fire management.

Are historical fire regimes compatible with future climate? Implications for forest restoration: Research Brief

Are historical fire regimes compatible with future climate? Implications for forest restoration: Research Brief

Future climate-induced shifts in fire regimes and plant distributions could uncouple vegetation from the fire regimes for which they are adapted. The brief discusses changes to fire-adapted plant communities under modeled climate change scenarios and their implications on the Kaibab Plateau landscape.

Maximum Fire Elevation in the Sierra Nevada Has Increased Over the Past Century: Research Brief

Maximum Fire Elevation in the Sierra Nevada Has Increased Over the Past Century: Research Brief

Using a geodatabase, researchers found that the maximum elevation extent of wildfires and the probability of wildfire occurrence above 3000 m have increased over the last century in the Sierra Nevada. This trend may accelerate vegetation shifts towards upper montane forest types in current subalpine systems.
