The chapters in this book highlight how far this silvicultural model has evolved over the past several decades, both in geographic extent and the diversity of forest ecosystems and management contexts for which natural models have been applied. In contrast to generic mischaracterizations of ecological silviculture as solely being co...AuthorsAnthony W. D'Amato, Brian J. PalikKeywordsSourceIn: Palik, Brian J.; D'Amato, Anthony W., eds.

- Red pine (Pinus resinosa Ait.) ecosystems of the western Great Lakes region of United States and Canada are the focus of this chapter. These forests are found in northern Michigan, Wisconsin, and Minnesota in the United States, and portions of southern Ontario, Canada. Historically, because of high economic value of red pine, this ecosystem has been managed using a timber-focused silvicultural system in both plantations and natural-origin stands, generally based on even-aged regeneration systems followed by planting of red pine. The timber-focused model results in composition and structure th...AuthorsBrian J. Palik, Anthony W. D'AmatoKeywordsSourceIn: Palik, Brian J.; D'Amato, Anthony W., eds.

- In forestry, the tools to carry out on-the-ground management are found in the toolbox of silviculture, that is, the part of forestry that deals with the development and care of forests. This development and care can be all encompassing, including establishment, growth, composition, health, and quality of trees and stands to meet the diverse needs of society. The planned program of all these activities, spanning the entire life of a forest stand, is termed a silvicultural system. Ostensibly, such a definition for silviculture would seem to recognize most forests, outside of plantations, as nat...AuthorsBrian J. Palik, Anthony W.

- Climate change is bringing rapid changes to the environment, including new temperature ranges and precipitation regimes. Some trees may no longer thrive and regenerate in their current locations, which in turn may reduce the ecosystem goods and services they have produced in the past.AuthorsNorthern Research Station USDA Forest ServiceKeywordsSourceFSYear2024
- Thermally modified woods are a nascent but growing industry in North America, which has seen an increase in both the number of producers as well as annual board footage of material produced. These products are being marketed as a sustainable alternative to tropical hardwoods in areas of non-structural, above ground application. The AWPA P9 committee (non-biocidal wood protection) is responsible for the establishment of Task Groups to consider nonbiocidal wood protection methods and the development of protocols for standardization. Thermally modified wood has been a continual action item on the...AuthorsMatt Aro, Mike Barnes, John Heyesen, Kelly Bartz, Glenn Larkin, Mark Mankowski, Rachel Arango, Grant T.

- Prior to use or sale, new termiticides must undergo a standardized test — and those efficacy data are subsequently submitted to the U.S. Environmental Protection Agency (EPA). The EPA has a specific methodology that is required for testing, and the agency relies on the U.S. Department of Agriculture (USDA) Forest Service (FS) Forest Products Laboratory Durability and Wood Protection unit to do the work. These data are used to determine whether tested concentrations, applied in the studies as a zone of treated soil, are effective at preventing damage to test wood blocks in three field locations...AuthorsThomas Shelton, Craig Bell, Shawn Cooper, Grant T.

- Applications of deep eutectic solvent (DES) systems to separate lignocellulosic components are of interest to develop environmentally friendly processes and achieve efficient utilization of biomass. To enhance the performance of a binary neutral DES (glycerol:guanidine hydrochloride), various Lewis acids (e.g., AlCl3⋅6H2O, FeCl3⋅6H2O, etc.) were introduced to synthesize a series of ternary DES systems; these were coupled with microwave heating and applied to moso bamboo. Among the ternary DES systems evaluated, the FeCl3-based DES effectively removed lignin (81.17%) and xylan (85.42%), signifi...AuthorsYingying Feng, Thomas Eberhardt, Fanyang Meng, Chen Xu, Hui PanSourceJournalYear2024
- This resource update is a brief look at some of the basic metrics that describe the status of and changes to forest resources in Arkansas. Estimates presented are for the 2022 survey year with resource changes compared to the 2021 survey year (Rosson 2022). This information is based on field data collected using the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) annualized sample design, and it is updated yearly. Arkansas has about 5,700 sample plots across the State; each year, 20 percent of these plots (one panel) are visited and measured by field crews, ...AuthorsJ.F. Jr..RossonYear2024
- A large share of the land in the United States is public. Public and government access to these lands have major implications for their management and recreational use as well as surrounding privately owned lands. Because of historical policies related to the distribution of public land, the government manages countless areas of inaccessible land that are commonly referred to as “stranded public lands.” This stranded public land has been shown to decrease county-level property values and has resulted in a higher risk of wildfire. However, past studies have focused on county-level information. ...AuthorsLinus Blomqvist, Bryan Leonard, Andrew J. Plantinga, Matthew R. Sloggy, José J.

- Background: Forests are significant terrestrial biomes for carbon storage, and annual carbon accumulation of forest biomass contributes offsets affecting net greenhouse gases in the atmosphere. The immediate loss of stored carbon through fire on forest lands reduces the annual offsets provided by forests. As such, the United States reporting includes annual estimates of direct fire emissions in conjunction with the overall forest stock and change estimates as a part of national greenhouse gas inventories within the United Nations Framework Convention on Climate Change. Forest fire emissions re...AuthorsJames E. Smith, Michael Billmire, Nancy H.F. French, Grant M. DomkeSourceCarbon Balance and ManagementYear2024
