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...

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...

The Timber Products Output (TPO) survey, administered by the Forest Inventory and Analysis (FIA) program of the USDA Forest Service, collects data annually from primary wood processing mills. The survey collects data on the volume of roundwood received and residues generated by the primary forest industry by major tree species and counties of harvest. Prior to 2019, the TPO survey was implemented as a full census of all active mills, with varying frequencies across FIA regions. For Southern FIA, TPO surveys of non-pulp mills were delivered every other year. From 2019 forward, TPO transition...

Innovation in packaging design will be facilitated by a simple test method to indicate whether a product is compatible with paper recycling. Three laboratories cooperated on the development of a method and used it on linerboard, coated paperboard, wet-strength paperboard, and white copy paper. This test method includes pulping and screening. The data presented here illustrate the factors affecting the results of a bench-scale test. Our observations show that a bench-scale test can give reproducible results for yield of less than 5%. We also present an approach to contaminant assessment...

This comment challenges claims made by the Forest Flows Programme (Meason et al., 2025) regarding the water use of Pinus radiata plantations and the water yield from pine-forested catchments across New Zealand. Using robust, previously established evidence, it is argued here that instead of dispelling some commonly held beliefs, Meason et al. have created new forest hydrological myths by underestimating pine-tree water use and overestimating subsurface flows based on an erroneous conceptualization of key processes and water-balance components. In the authors' view, this not only renders...

We revisit the research legacy of J.R. Blais and re-evaluate his contributions to spruce budworm—forest dynamics in light of a century of research, 1924–2025. We trace the evolution of scientific thought on outbreak ecology and reassess Blais’ foundational insights using contemporary data and methods. Blais’ alignment with a bottom-up, host-driven outbreak paradigm—centered on forest composition and epicentric spread—anticipated many findings now supported by modern research. Re-analysis of Blais’ historical outbreak maps (1802–1940) reveals a longitudinal gradient in outbreak frequency...

Wildfire risk has risen significantly due to climate change and the increase in housing development in the wildland urban interface (WUI), making household participation in fuel reduction crucial. However, homeowners’ perceived wildfire risk may diverge from professionals’ objective assessments. We use a choice experiment survey of Arizona homeowners in WUI areas to compare how willingness to pay (WTP) for public and private fuel reduction programs aligns with self-assessed versus professionally determined wildfire risk. Results show that while homeowners’ WTP for fuel reduction is...

Urbanisation has led to increasing homogenization of plant communities across cities. However, it is unclear whether these patterns extend to cosmopolitan plant species at the genetic level. We examined genome‐wide genetic patterns in six widespread plant species (three Poaceae and three Asteraceae) across five cities in the USA (Boston, Baltimore, Minneapolis‐St. Paul, Phoenix, and Los Angeles) using reduced‐representation sequencing. We assessed genetic structure, differentiation, and patterns of isolation by distance (IBD) and environment (IBE) to determine if species were genetically...

Turnover in species composition often lags behind the pace of climate change, resulting in mismatches between climate and communities. However, the impact of these community‐climate disequilibria on ecosystem functions is rarely considered, and current methods for measuring disequilibria assume that species ranges were, until recently, in equilibrium with climate. Here, we develop a simple theoretical model to address both of these problems by linking community‐climate disequilibrium with ecosystem functioning. We show how disequilibrium can impair functioning in the near‐term even when...

For the past 20 years, approximately twice as many trees were removed annually from urban areas in the USA as were harvested annually from the US National Forest System. Yet, most of this wood is treated as waste instead of as a valuable resource to generate economic growth and sustainable cities. Residential landowners are key actors in the establishment of local urban wood economies as both sources of material and users of urban wood products, yet they remain a difficult to reach group compared with others, such as tree care companies, mill operators, and public landowners.We analyze a...
