Domestic selection creates the assemblages of organisms found in human-dominated environments, and urban forestry is a useful illustration of this process in action. In this study, we aim to understand how the process of domestic selection influences the nursery supply chain of trees to Baltimore, Maryland, USA. We interviewed actors in the supply chain to ask how they make decisions about which trees to grow, sell, select, and plant. We find tension between prioritizing diversity (at the species or genetic level) and other factors such as planting site conditions, esthetics, availability,...

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 Maryland. 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...

Data collected from over 200 plots in Milwaukee, Wisconsin from 2015 through 2021 reveal that the city has an estimated 3.7 million live trees at least 1.0 inch in diameter across all ownerships. The most common tree species by number are common buckthorn, boxelder, and green ash, while those at least 5.0 inches in diameter are led by green ash, boxelder, and Norway maple. The largest number of trees (31.4 percent; 1.1 million trees) are found on forest land. Trees on public lands total 2.1 million and account for over 57 percent of all live trees. Trees at least 15.0 inches in diameter...

Biomass harvesting is common across the northeastern United States, yet plant and soil responses in the years-to-decades after harvest are poorly understood. We assessed regenerating species composition and foliar and soil element concentrations after clearcutting with whole-tree harvesting, stem-only harvesting, and stem-only harvesting with prescribed burning in spruce-fir-hardwoods in Maine, U.S.A. We made measurements 50 years after the first treatment (applied 1964–65) and within 10 years after the second treatment (applied 2018), providing one of the longest evaluations of biomass...

The 2020 inventory of the forests of the Northern Great Plains States (Kansas, Nebraska, North Dakota, and South Dakota) reports more than 6.6 million acres of forest land and more than 2.1 billion trees. Forest land is dominated by the ponderosa pine, sugarberry/hackberry/elm/green ash, and elm/ash/black locust forest types, which together occupy 43 percent of the total forest land area. The volume of growing stock on timberland currently totals 3.9 billion cubic feet. The average annual net growth of live trees from 2014 to 2020 was 162.5 million cubic feet per year. This report includes...

This resource update contains the findings of a survey conducted on a sample of all primary wood-using mills in the state. It complements the Forest Inventory and Analysis (FIA) annual inventory of volume and removals. The survey was conducted to determine the amount and source of wood receipts and annual timber product imports/exports. Only primary wood-using mills were surveyed. Primary mills are those that process roundwood in log or bolt form or as chipped roundwood. Examples of industrial roundwood products are saw logs, pulpwood, veneer logs, poles, and logs used for composite board...
