Abstract Background Over the last four decades, wildfires in forests of continental western United States have significantly increased both size and severity after more than a century fire suppression exclusion. Many these historically experienced frequent were fuel limited. To date, reduction treatments been small too widely dispersed to impacted this trend. Currently new land management plans are being developed on most 154 National Forests that will guide support ground practices for next 15–20 years. Results During plan development, we recommend Strategic Fire Zones (SFZs) be identified large blocks (≥ 2,000 ha) Federal forest lands, buffered 1–2.4 km) from wildland-urban interface reintroduction beneficial fire. In SFZs, lightning ignitions, as well prescribed cultural burns, would used reduce fuels restore ecosystem services. Although such successfully established limited number Parks Wilderness Areas, identify extensive remote areas US (8.3–12.7 million ha), outside wilderness (85–88%), where they could established. Potential wildland Operational Delineations or PODs SFZ boundaries. We outline steps identify, implement, monitor, communicate use benefits SFZs. Conclusions Enhancing collaboration knowledge-sharing with Indigenous communities can play vital role gaining agency public building narrative how rebuild climate-adapted regimes live within them.

A clear understanding of the connectivity, structure, and composition wildland fuels is essential for effective wildfire management. However, fuel typing mapping are challenging owing to a broad diversity conditions their spatial temporal heterogeneity. In Canada, types potential fire behavior characterized using Fire Behavior Prediction (FBP) System, which uses an association approach categorize vegetation into 16 based on stand structure composition. British Columbia (BC), provincial national FBP System type maps derived from remotely sensed forest inventory data widely used operations, management, scientific research. Despite widespread usage, accuracy applicability these have not been formally assessed. To address this knowledge gap, we quantified agreement between on-site assessments in interior BC. We consistently found poor correspondence field assessment both types. Mismatches were particularly frequent (i) dry ecosystems, (ii) mixedwood deciduous types, (iii) post-harvesting conditions. For 58% plots, there was no suitable match extant driven by availability low Canadian BC fuels. The mismatches identified can limit research, but also challenge operations management decisions.

Contemporary reference sites in California's Sierra Nevada represent areas where a frequent, low-intensity fire regime - an integral ecological process temperate dry forests has been reintroduced after several decades of suppression. Produced by intact regime, forest structural patterns these are likely more resilient to future disturbances and climate, thus can provide conditions guide management research. In this paper, we present set 119 delineated contemporary the yellow pine mixed-conifer zone along with suite key remote sensing-derived structure metrics representing within sites.

Abstract The frequency and severity of drought events are predicted to increase due anthropogenic climate change, with cascading effects across forested ecosystems. Management activities such as forest thinning prescribed burning, which often intended mitigate fire hazard restore ecosystem processes, may also help promote tree resistance drought. However, it is unclear whether these treatments remain effective during the most severe conditions or their impacts differ environmental gradients. We used tree‐ring data from a system replicated, long‐term (>20 years) experiments in southwestern United States evaluate restoration (i.e., evidence‐based burning) on annual growth rates basal area increment; BAI) ponderosa pine ( Pinus ), broadly distributed heavily managed species western North America. study sites were established at onset extreme event least 1200 years span much climatic niche Rocky Mountain pine. Across sites, tree‐level BAI increased treatment, where trees treated units grew 133.1% faster than paired, untreated units. Likewise, an average 85.6% pre‐treatment baseline levels (1985 ca. 2000), despite warm, dry post‐treatment period (ca. 2000–2018). Variation local competitive environment promoted variation BAI, larger fastest‐growing individuals, irrespective treatment. Tree altered constraints growth, decreasing belowground moisture availability increasing atmospheric evaporative demand over multi‐year timescales. Our results illustrate that can enhance spanning pine's niche, even recent, events. shifting constraints, combined increases States, suggest beneficial wane upcoming decades.
