In sectors based on renewable resources, foresight studies have often been macro‐scale, quantitative outlook studies. As a result, in the complex operating environment of the forest bioeconomy, the organizations and professionals of the emerging bioeconomic sector have not been able to fully utilize futures information in their decision‐making processes. This study sought to find solutions to this issue by utilizing a nested business environment framework (NEST framework) in signal interpretation as part of piloting interactive horizon scanning of the forest bioeconomy. In interaction with...

The Urban National Landowner Survey (UNLS) is a component of the National Woodland Owner Survey (NWOS) which is part of the U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program. The UNLS is charged with collecting information on the property owners and managers in the urban areas across the United States. Information is collected on ownership and land characteristics, property management activities, tree-related concerns on their property, participation in programs and organizations, information sources, opinions on neighborhood and community...

The Urban National Landowners Survey (UNLS) provides information about who owns the trees across America’s urban areas, why they own them, what they have done with them in the past, and what they plan to do with them in the future. The first UNLS was completed for Baltimore, MD, in 2018 and provides estimates for all landowners in the city. Most people in Baltimore valued trees on their property and in their neighborhood evidenced by the following: they agreed that trees make the neighborhood a better place to live, that tree health should be considered during construction, and that good...

Many researchers have identified and described different segments of family forest owners. This report describes one segmentation scheme that has been developed and used by the Tools for Engaging Landowners (TELE) program using National Woodland Owner Survey data. TELE divides landowners into four broad groups based on their reasons for owning land. Because this segmentation scheme focuses on motivations, it is a particularly useful grouping strategy for designing communications with landowners. The first part of the paper describes the current (2018) TELE segments and shows how they...

Reliable interpretation of fire pattern indicators is essential for wildland fire origin investigations, yet experimental validation is scarce. Damage Differential in the context of this study refers to the measurable changes in combustible and noncombustible objects after fire exposure, enabling the comparison and contrast of fire-caused effects on different faces or zones of artifacts, as described in NWCG PMS 412 (2025, 2016, 2005) and NFPA 921. The principle was quantifiably applied using image analysis and statistical methods (ANOVA) to evaluate directional reliability under controlled...

Homeowners’ willingness to pay for urban forest benefits can be inferred from hedonic property value studies, which use real estate transactions to estimate the elasticity between home value and tree canopy cover (i.e., the % change in home value for a 1 % change in tree cover). We compiled a meta-dataset of 17 hedonic studies to predict this elasticity for 64,658 urban census tracts across the contiguous United States. Three benefit transfer methods were evaluated: matching value transfer using a nearest-neighbor technique, unit value transfer using weighted mean elasticities, and...

The world-wide diversity of ash trees includes genetic information encoding resistance to the ash dieback fungus and the emerald ash borer beetle, which are currently devastating ash populations in Europe and North America. In order to mobilise this genetic diversity in conventional breeding programmes, we need to be able to accurately identify ash species from around the world and cross them with one another. Here, we present a preliminary genetic barcoding system for ash, and a series of hybridisation experiments between European ash and other species. Two of the hybrids show early...

Forests provide critical ecological and economic services in Bhutan. After reports of a heavy adelgid infestation damaging trees in a forest nursery in Changaphu in 2019, a country-wide survey was conducted between 2020 and 2022. Eight adelgid species were found. Four were described elsewhere before this survey: Adelges (Annandina) tsugae Annand, Ad. (Gilletteela) glandulae, Pineus (Pineus) armandicola Zhang, Zhong and Zhang, and P. (P.) wallichianae Yaseen and Ghani. The remaining 4 were new species described in a separate paper: Ad. (Cholodkovskya) changaphuensis Havill and Brunet, Ad....

This literature review synthesizes recent research on use of stable isotopes to advance forest ecosystem management. Stable isotopes provide insights into soil fertility, nutrient cycling, climate variability, and pollution impacts by tracing carbon, nitrogen, and water dynamics. Microbial activity influences on soil conditions are also highlighted. Integration of soil metrics with genomic and forest management strategies allows for an understanding of carbon sequestration and soil health while supporting adaptive approaches to climate change. Seasonal variations in nitrogen uptake and the...

Understanding the spatial and demographic structure of local outbreaks is critical for identifying the ecological mechanisms underlying invasive forest insect dynamics.We investigated a population outbreak of Sirex noctilio within a pine plantation in Patagonia by integrating spatial analyses of infestation patterns with quantification of oviposition behaviour and adult performance.At the plot level, the distribution of infested trees shifted from a highly clustered pattern in previous seasons to a more spatially dispersed one of newly attacked treesLogs sampled from S. noctilio ‐infested...
