- Public lands provide extensive recreation opportunities for activities including camping and cabins, biking, horseback riding, hiking, and fishing. Due to increasing visitation and the associated impacts to natural resources and the visitor experience, recreation managers may decide to adopt a recreation allocation strategy to limit the number of visitors at a given time. Allocation includes allotment (splitting between groups such as commercial use and private use) and rationing (a mechanism for allocating within groups). The main strategies used for rationing include first come, first...AuthorsAndrea Watts, Chris A. ArmatasKeywordsSourceScience You Can Use (in 5 Minutes), March 2026.

- Demand for recreation on public lands has outpaced supply in many highly popular locations in the United States of America and globally. The task of distributing these limited recreation opportunities among individuals or groups (known as allocation) has long plagued recreation managers. However, limited empirical information is available concerning best practices for selecting an allocation mechanism (e.g., permits available through first-come, first-served, open reservations, lotteries, etc.) that best meets the management objectives and constraints of a given site—including temporal...AuthorsKelsey E.

- To effectively manage fire, land and fire managers need detailed, current local information - for example, the amount of burnable material present, fuel moisture levels, winds, temperatures, and terrain changes across time and space. Managers also need these data to decide where, when, and how to treat a landscape while balancing costs and benefits, projected wildfire risk, and potential impacts.AuthorsAnnabelle Moore, John S. HoglandKeywordsSourceScience You Can Use ToolYear2026
- Community wildfire readiness includes homeowner wildfire risk mitigation and wildfire evacuation preparedness. This report presents results from a household survey distributed to homeowners in the study area around Santa Fe, New Mexico in 2024 which was a follow-up to a previous survey of homeowners of the same residences, consisting of mostly identical questions, that was conducted in 2021. This follow-up survey was motivated by the nearby 2022 Hermit’s Peak/Calf Canyon Fire. Comparison of results indicates general stability in the aggregated responses to most survey questions. As found...AuthorsJames R. Meldrum, Colleen Donovan, Suzanne Wittenbrink, Porfirio Chavarria, Patricia A. Champ, Hannah Brenkert-Smith, Christopher M.

- Whitebark pine (WBP) is a federally threatened species that is easily killed by fire but also dependent on fire. In WPB forests, prescribed burning and mechanical fuel treatments can reduce competition from shade-tolerant conifers, improve vigor of surviving WBP, create openings to foster regeneration of WPB seedlings, and mitigate the risk of large, high-severity wildfires. Burning in WBP stands requires careful planning to avoid killing reproductively mature, cone-bearing WBP, as many of these may have some level of genetic resistance to the exotic pathogen that causes white pine blister...AuthorsSharon M.

- Tree longevity is thought to increase in growth-limiting, adverse environments, but a quantitative assessment of drivers of global variation in tree longevity is lacking. We assemble a global database of maximum longevity for 739 tree species and analyse associations between longevity and climate, soil, and species’ functional traits. Our results show two primary pathways towards long lifespans. The first is slow growth in resource-limited environments, consistent with the “adversity begets longevity” paradigm. The second pathway is through relief from abiotic constraints in productive...AuthorsRoel J. W. Brienen, Giuliano Maselli Locosselli, Stefan Krottenthaler, Emanuel Gloor, Robyn Wrigley, Steven L.

- Wildland-urban (WU) fires can devastate lives and communities, overwhelm emergency response efforts, and exhaust sheltering and recovery resources. Rapid fire spread into communities accounted for 78% of structure loss over 2001–2020, and rates of structure loss from such wildfires increased by 160% from 2010 to 2020 over the prior decade (1, 2). These fires carry enormous societal costs, including mortality, morbidity, loss of critical infrastructure and services, home destruction, and loss of insurance coverage (3, 4).AuthorsMatthew P.

- As the northern high-latitude permafrost zone experiences accelerated warming, permafrost has become vulnerable to widespread thaw. Simultaneously, wildfire activity across northern boreal forest and Arctic/subarctic tundra regions impacts permafrost stability through the combustion of insulating organic matter, vegetation, and post-fire changes in albedo. Efforts to synthesis the impacts of wildfire on permafrost are limited and are typically reliant on antecedent pre-fire conditions. To address this, we created the FireALT dataset by soliciting data contributions that included thaw depth...AuthorsAnna C. Talucci, Michael M. Loranty, Jean E. Holloway, Brendan M. Rogers, Heather D.

- Native fish populations and their habitats are declining in the southwestern United States. The upper Verde River (UVR) is one of a shrinking number of remaining perennial stream systems where multiple populations of native fish species still exist. This study utilized unoccupied aerial vehicle (UAV), terrestrial lidar, real-time kinematic (RTK) survey technology and environmental DNA (eDNA) sampling to assess current riparian and in-stream habitat conditions and compare them to an assessment conducted in 2009 to assess current suitability and long-term trends in populations and habitat...AuthorsJackson M.

- Environmental DNA (eDNA) sampling to monitor wildlife presence has mostly focused on water but increasingly includes soil, air, and creative biotic substrates like flowers and spiderwebs. Biotic substrates are unique in that they also provide insight into ecological interactions. Here we explore the ability of eDNA from songbird nests to reveal avian trophic ecology, such as nestling diet and nest predator identity, in addition to local insect biodiversity. Twenty‐two nests comprising five New World sparrow species and two nonsparrow passerines were collected in a montane sagebrush steppe...AuthorsJohn Kronenberger, Elise C.
