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...

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...

Spanish juniper, Juniperus thurifera L, forests are typically managed as uneven-aged forests in the Iberian range, which requires information about site index (SI) classes and diameter at breast height (dbh) distributions. The objective of this study is to evaluate and compare the performance of remote sensing models using multitemporal airborne laser scanning (ALS) data, Landsat metrics of state and change along with topographic, geographic and climatic predictors for the prediction of SI classes and diameter distributions. The best model for SI classes was a logistic model that showed an...

In 2020, six wildfires burned more than 1 million acres over the Labor Day weekend in Oregon. Jeremy Fried, a research forester with the U.S. Forest Service, Pacific Northwest Research Station, saw an opportunity to study how these wind-driven megafires affected forest structure and carbon storage, and how forest structure before the fires may have influenced fire severity.With research fellows Sebastian Busby and Angela Klock, Fried developed a model that estimated wind speed when wildfire entered forest plots previously inventoried through the national Forest Inventory and Analysis...

Background: The reintroduction of fire, with the goal of reducing fuels and restoring forest resilience, is a critical management practice in dry conifer forests of the western United States. In dry forest landscapes, invasion by non-native annual grasses could complicate restoration goals if fire exacerbates invasion and associated impacts, particularly in areas with low tree cover and in adjacent open areas. Although annual grasses are becoming increasingly pervasive across the West, little is known about how species differ in their response to burning, especially in historically...

Forest ecosystems provide essential services such as timber, water regulation, biodiversity, and recreation, yet they are increasingly influenced by the interplay between climate and socioeconomic forces. This study synthesizes findings from the 2020 Resources Planning Act (RPA) Assessment to evaluate how these factors affect historical trends and future projections of U.S. forest conditions and services. Results show that total forest area is projected to decline slightly by 2070, mainly due to conversion to developed land, with the greatest losses occurring in the South. While socioeconom...
