Wildfire extent is growing in the United States (US), a fact attributable to increasingly favorable weather and climatic conditions and the net result of human interventions. US federal land management agencies act upon the wildfire threat by managing hazardous fuels, discouraging human‐caused ignitions, and suppressing active fires. Costs of these actions are rising, so policy makers and wildland managers seek information that can help them understand the trade‐offs of resource allocations. This study generates new information about potential future wildfire and suppression demands by...

The Community Forestry (CF) program in Nepal is often lauded as a successful global example of the participatory forest management model, particularly for restoring degraded forest in the midhills However, recent socio-economic, demographic, ecological, and governance change have transformed forest-people relationships, creating uncertainty about the program's long-term sustainability. In this context, this study aims to identify the socio-ecological and institutional factors shaping community forest users' perceptions of the future of CF in Nepal. Using survey data from 873 households...

Collaborative governance plays a critical role in wildfire risk mitigation efforts. This study examines collaborative wildfire governance networks within the Colorado Front Range, a landscape that was designated under the USDA Forest Service's Wildfire Crisis Strategy (WCS). Collaborative governance networks in the Colorado Front Range leverage partnerships across multiple organizational actors including federal, state, and local agencies, non-profits, fire districts, and research institutions. Through survey data collected from 281 respondents revealing a collaborative network of 401...

The U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program provides this resource update yearly as an overview of forest resources in Texas. These estimates are derived from field data collected across a systematic network of fixed-radius forest monitoring plots located on both public and private land. New updates are provided annually as a subset of plots within the State are remeasured. Each year, field crews visit and measure a subset of all FIA plots across the entire State (the size of the subset varies by State and year). Combining all the...

Macrochelys temminckii (Alligator Snapping Turtle) is a large freshwater turtle that occurs in a broad range of stream orders in the southeastern US. The species has experienced range contraction and population declines throughout its range. Environmental DNA (eDNA) sampling is an effective method for indirect detection of the Alligator Snapping Turtle when trapping or radio tracking is not feasible. Environmental conditions and resource availability vary across stream orders, potentially influencing Alligator Snapping Turtle occupancy patterns and eDNA detection probabilities. In this...

The U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program provides this resource update yearly as an overview of forest resources in Virginia. These estimates are derived from field data collected across a systematic network of fixed-radius forest monitoring plots located on both public and private land. New updates are provided annually as a subset of plots within the State are remeasured. Each year, field crews visit and measure a subset of all FIA plots across the entire State (the size of the subset varies by State and year). Combining all...

Evaluating the cost of fuel treatment operations is an essential aspect for mitigating elevated wildfire risks across western US landscapes. The USDA Forest Service (Forest Service) currently uses a Transaction Evidence Appraisal (TEA) method to appraise stumpage, incorporating key factors such as stump-to-truck processing, slash disposal, transportation, timber markets, and bidder competition. This study aims to improve our understanding of the total costs involved and final advertised rates in fuel treatment operations in Forest Service Regions 2 and 3. Stump-to truck processing and...

Logging businesses in Idaho perform timber harvesting and fuel reduction treatments on the state’s 21.5 million acres of forestland and supply raw material to its $2.5 billion forest products industry which employs more than 30,000 people. We conducted a survey of Idaho logging and forestry contracting businesses during spring and summer of 2025 in cooperation with the Associated Logging Contractors of Idaho (ALC), Inc. to better understand owner and employee demographics, business structure, capital investment, equipment used, and challenges faced.

Pristine crawfish shell waste and shell-derived biochars produced at 500, 650, and 800 ◦C were evaluated as calcium-rich sustainable biosorbents for Nd(III) immobilization from aqueous solution. Batch experiments were conducted at 23 ◦C using 50 mL of 1000 mg L-1 Nd(III) solution and sorbent mass of 25–100 mg to investigate removal behavior, kinetics, and mechanisms. The 800 ◦C biochar exhibited the highest apparent Nd(III) removal capacity (1200 mg g-1), which was attributed to instantaneous alkaline precipitation and the formation of Nd (OH)3. In contrast, pristine crawfish shell and the...

The USDA Forest Service’s Forest Inventory and Analysis (FIA) program, the United States’ national forest inventory operating since 1928, has undergone two independent Blue Ribbon Panel (BRP) reviews (1991–92, 1997–98) that drove major improvements, including the transition toward a nationally consistent annualized inventory system and integration of forest health monitoring. Today, FIA faces unprecedented demands from data-driven markets, intensifying disturbances, supply chain volatility, and sustainability frameworks requiring verified, frequently updated data at sub-county scales...
