A 2018 analysis of the urban forest in Springfield, Missouri reveals that this area has an estimated 3.6 million live trees across all ownerships, two-thirds of which are under 5.0 inches in diameter. The most common large diameter (11.0+ inches in diameter) tree species are black walnut, silver maple, and hackberry. The most common tree species in maintained areas of the city are Siberian elm, eastern redbud, and hackberry. Trees in Springfield are estimated to be currently storing about 342,000 tons of carbon (1.3 million tons of carbon dioxide) valued at $58.4 million. In addition, it...

A survey of the urban forest was conducted in Providence, Rhode Island from 2015 to 2021. Across the 13.1 thousand acres encompassing the city, there are an estimated 495.2 thousand live trees. More than half of tree stems are small diameter (under 5.0 inches in diameter). The most dominant species based on the number of trees and leaf area are Norway maple, black oak, northern red oak, American elm, and northern white-cedar. Trees on public lands account for 30.0 percent of the total live tree population. Trees on private lands account for 70.0 percent. A majority of trees on private land...

A 2021 analysis of the urban forest in Des Moines, Iowa, reveals that this area has an estimated 2.5 million live trees across all ownerships. The most common tree species by number are American elm, green ash, and boxelder. Trees in Des Moines are estimated to store about 466,000 tons of carbon (1.7 million tons of carbon dioxide [CO2]) valued at $79.5 million. In addition, it is estimated that these trees remove about 12,000 tons of carbon per year (or 44,000 tons CO2 per year, valued at $2.1 million, an amount roughly equivalent to the annual emissions associated with 8,700 passenger...

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 Michigan. 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 Wisconsin. 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 South Dakota. 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...

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 Connecticut. 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...

Ecological connectivity models commonly derive resistance surfaces from habitat suitability; however, it remains unclear how two-dimensional (2D) versus three-dimensional (3D) representations of landscape propagate through this modeling pipeline, particularly in urban environments. This study evaluated the sensitivity of habitat suitability and connectivity outputs derived from these models to the inclusion of 3D landscape structure for two bird species with contrasting habitat associations, the Western Bluebird (Sialia mexicana) and Acorn Woodpecker (Melanerpes formicivorus), in Los...

Climate change is expected to alter the extent and severity of forest pest damage, with substantial economic and ecological consequences, but predicting future pest impacts is challenging because of complex feedbacks among climate, pests and host trees. Here we use 20 years of data from the conterminous USA to assess how bioclimatic and biotic factors have influenced forest damage by 30 high-impact pest species and to identify ecological signals in those relationships. We found consistency in pest damage responses to maximum temperature in the warmest month, including recent average...

Climate change is affecting nearly all social and environmental determinants of health. However, the extent of resulting cumulative impacts on cardiovascular and other noncommunicable diseases is not known. To address this gap and inform future research, we conducted an ecological evaluation of associations between 14 long‐term climate anomaly metrics and prevalence of coronary heart disease (CHD) and stroke in the United States. We calculated long‐term anomaly metrics as the difference between their respective 1970–1979 baseline mean and 2013–2022 modern mean values. With fitted random...
