Abstract Fuel and restoration treatments seeking to mitigate the likelihood of uncharacteristic high‐severity wildfires in forests with historically frequent, low‐severity fire regimes are increasingly common, but long‐term treatment effects on fuels, aboveground carbon, plant community structure, ecosystem resilience, other attributes understudied. We present 20‐year responses thinning prescribed burning commonly used dry, low‐elevation western United States from a study site Northern...
Abstract The national Fire and Surrogate (FFS) study was initiated more than two decades ago with the goal of evaluating ecological impacts mechanical treatments prescribed fire in different ecosystems across United States. Since then, 4 original 12 sites remain active managing monitoring FFS which provides a unique opportunity to look at long‐term effects these regions. These include California (Blodgett Forest Research Station), Montana (Lubrecht Experimental Forest), North Carolina (Green...
Many western USA fire regimes are typified by mixed-severity fire, which compounds the variability inherent to natural regeneration densities in associated forests. Tree data often discrete and nonnegative; accordingly, we fit a series of Poisson negative binomial variation models conifer seedling counts across four distinct burn severities three forest types 10 years after 23,000-ha Storrie Fire, large northern California. Despite accessibility power zero-inflated mixture model, flexible...
Ongoing revitalization of the >5000-year-old tradition using trees for vital culture and heritage activities including carving weaving affirms Alaska Native resilience. However, support these sustained cultural practices is complicated by environmental political factors. Carving projects typically require western redcedar (Thuja plicata) or yellow cedar (Callitropsis nootkatensis) more than 450 years age—a tree life stage growth rate inconsistent with current even-aged forest management...
Wildfires are increasing in scale and impact on the landscape, altering large amounts of wildlife habitat forest ecosystems. The reduction fuels through management is considered a primary way to reduce extent severity wildfires before they occur but may lead decrease tree density prohibitive some species' habitat. Alternatively, actions undertaken after fire speed trajectory burned areas back into quality also impede this development if wrong type treatment undertaken. Thus, information how...
Fuel reduction treatments have been widely implemented across the western US in recent decades for both fire protection and restoration. Although research has demonstrated that combined thinning burning effectively reduces crown potential few years immediately following treatment, little identified effectiveness of beyond a decade. Furthermore, it is unclear how post-treatment disturbances such as bark beetle outbreak affect fuel treatment effectiveness. We evaluated differences surface...
Abstract In the western United States, restoration of forests with historically frequent, low‐severity fire regimes often includes fuel reduction that reestablish open, early‐seral conditions while reducing continuity and loading. Between 2001 2016, (e.g., thinning, prescribed burning, etc.) was implemented on over 26 million hectares federal lands alone in reflecting urgency to mitigate risk from high‐severity wildfire. However, between 2012, nearly 20 States were impacted by mountain pine...
In southeast Alaska, United States, multiple-use forest management objectives include both timber production and wildlife habitat. Following stand-replacing disturbances such as clear-cutting, Sitka spruce (Picea sitchensis (Bong.) Carrière) western hemlock (Tsuga heterophylla (Raf.) Sarg.) naturally regenerate competitively dominate resources, excluding understory biomass biodiversity. Thinning may mitigate the effects of canopy closure permit development, but evidence effect on...
Variable-retention harvesting in lodgepole pine offers an alternative to conventional, even-aged management. This technique promotes structural complexity and age-class diversity residual stands resilience disturbance. We examined fuel loads potential fire behaviour 12 years after two modes of variable-retention (dispersed aggregated retention patterns) crossed by post-harvest prescribed (burned or unburned) central Montana. Results characterise 12-year post-treatment loads. found greater...
Western larch forests are iconic in the interior northwest, and here we document preemptive steps that scientists managers taking to steward these into future. Changing climate is forecast have acute chronic impacts on growth disturbance western forests. A group of northern Rocky Mountains teamed up with Adaptive Silviculture for Climate Change Network an experiment proactively manage adaptation. The collaborative developed a gradient adaptation treatments (i.e., resistance, resilience,...
Research Highlights: This study provides much needed insight into the development of resistance to disturbance and growth dynamics overstory trees in response restoration-based fuel reduction, will be useful scientists managers attempting better grasp relative merits restoration treatment types. Background Objectives: Restoration-based reduction treatments are common dry, fire-prone forests western United States. The primary objective such is immediately reduce a stand’s crown fire hazard....
The Blacks Mountain Experimental Research Project created two distinct overstory structural classes (high-structural diversity [HiD]; low-structural [LoD]) across 12 stands and subsequently burned half of each stand. We analyzed stand-level growth 10 years after treatment then modeled individual tree to forecast 10–20 treatment. Net stand was compared between treatments with adjacent Natural Areas (RNAs). An analysis variance in total aboveground biomass suggested that greatest unburned (P =...

Abstract Precommercial thinning and tree pruning are frequently used together to improve timber quality wildlife habitat in even-aged Sitka spruce (Picea sitchensis) western hemlock (Tsuga heterophylla) stands. Thinning enhances crop growth understory plant production; however, the benefits drawbacks of have received less attention. Tree was investigated two long-term experiments on Tongass National Forest, Alaska, USA. Experiment 1 tracked four uniformly thinned sites for ~30 years that...
Quantifying forest understory biomass is important for understanding ecological processes, but there are few methods non-destructive measurement of in southeast Alaska. We developed cover-to-biomass equations common species young-growth Sitka spruce (Picea sitchensis)–western hemlock (Tsuga heterophylla) forests. A sampling method visually estimating cover and destructively measuring was used at 35 stands aged 10 to 67 years on Prince Wales Island Alaska from 2007 2018. Linear regressions...
