Diseases are threatening forests worldwide. In North America, white pine blister rust (WPBR) is one of the most damaging tree epidemics. To understand patterns in the current and future risk for high-elevation five-needle white pine species (High-5), we compiled data from independent studies across the western U.S. to estimate WPBR risk. Contrary to previous predictions, the future climate is not expected to reduce the prevalence of WPBR risk on High-5 species in the western U.S. The prevalence of WPBR is predicted to increase, with most distributions of the High-5 species projected to...

Outcomes of European colonization encompass surface fire exclusion followed by the forestation of open ecosystems and tree densification within forests, with concomitant replacement of fire-tolerant tree species, specifically oaks, by fire-sensitive tree species. In Kentucky, a 10.5 million ha area of the eastern United States, I compared tree composition between a historical assessment (1907–1909) and modern surveys (2010–2014), utilizing a divergence metric of squared-chord distance, which revealed a similar progression. Following the time since Euro-American settlement and associated...

Suitable climate for tree species currently located in Mexico may shift to the United States and Canada under future warming, resulting in the potential for tree species shifts, with new species gained in the USA and Canada and species losses in Mexico. To isolate dynamics, I modeled distributions of 184 commonly recorded wideranging or transboundary tree species of North America, including presence in Mexico, and 258 tree species primarily abundant in Mexico, including 51 endemic species, under current climate and predicted to three future climates (projected warming of 4.3–8.8 ◦ C during...

The Urban National Landowner Survey (UNLS) is part of the U.S. Department of Agriculture (USDA), Forest Service, Forest Inventory and Analysis (FIA) program and has the mission of providing information about the ownership, objectives, management, and future plans of people who own trees in urban areas. This report summarizes data collected from private, residential landowners in Houston, TX, from 2019 (n = 209). While normally collected over 5 years, implementation was intensified in Houston to complete data collection in 1 year. Private, residential landowners in Houston believe that...

This report provides detailed estimates and highlights key findings from U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) data collected across its Alaska Susitna-Copper FIA unit in 2019 and 2020. The Susitna-Copper FIA unit encompasses much of the Susitna River and upper Copper River watersheds and is one of six FIA inventory units designed to measure the expansive boreal forests of Alaska. Estimates of forest area, volume, aboveground biomass, and ecosystem carbon are provided across land ownerships, forest types, and forest demographics throughout the...

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 Florida. 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 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 Vermont. 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 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 Rhode Island. 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...

Wood Turtle (Glyptemys insculpta) populations are declining in many portions of the species’ native range due to multiple factors that might influence functional connectivity and population genetic structure. We used 13 microsatellite markers to examine patterns of genetic structure in the Wood Turtle across its native range in Eastern and Midwestern North America. For n = 45 collections with 15 or more individuals (total N = 1,258), multiple clustering approaches revealed two major genetic groups corresponding to the midwestern and eastern collections. Interestingly, a sample from lower...

This article uses a knowledge exchange (KE)-based approach to evaluation to explore the reported experiences of artists, scientists, and land managers participating in the NaturePLACE Program (formerly Urban Field Station [UFS] Arts), focusing on the period 2016–2024. The primary aim of the program is to build understanding of and engagement with urban social-ecological systems through the arts. The approach to this evaluation draws on a range of literature on research in the arts, as well as research and KE impact evaluation from the environmental research domain. The evaluation reported...
