Large-scale global reforestation goals have been proposed to help mitigate climate change and provide other ecosystem services. To explore potential in the United States, we used GIS analyses, surveys of nursery managers foresters, literature synthesis assess opportunities challenges associated with meeting goals. We considered a scenario where 26 million hectares (64 acres) natural agricultural lands are reforested by 2040 30 billion trees at an estimated cost $33 ($24–$53) USD. Cost per...
Climate and longleaf pine (Pinus palustris P. Mill.) radial growth relationships have been documented within its southern western distribution. However, knowledge of this relationship is lacking along northern latitudinal range margin (NLRM). Based on the principles ecological amplitude, limiting factors, studies coniferous species in eastern temperate forests U.S., we hypothesized that mixed pine-hardwood responding to winter temperatures southeastern Virginia. Two chronologies were...
Disturbance regimes of many hardwood forests the eastern United States in complex stage development are characterized by localized canopy disturbance events that change fine-scale biophysical conditions. Recently, research has demonstrated importance gap-scale processes secondary stands southern Appalachian Highlands. However, information on patterns during early developmental stages is required from broader geographic region for a comprehensive understanding stand dynamics. The goal this...
Removal of canopy dominant trees in temperate closed-canopy forests due to natural or anthropogenic disturbance may allow for the release co-dominant and sub-canopy into canopy. Historical growth releases these can be reconstructed from analysis their annual rings compared with historical events better understand forest dynamics. We applied boundary-line patterns, a method reconstruction disturbance, annual-ring series longleaf pine two successional sites (Everwoods Seacock Swamp)...
The longleaf pine ( Pinus palustris Mill.) and related ecosystem is an icon of the southeastern United States (US). Once covering estimated 37 million ha from Texas to Florida Virginia, near-extirpation of, subsequent restoration efforts for, species has been well-documented over past ca. 100 years. Although one longest-lived tree in US—with documented ages 400 years—its use not reviewed field dendrochronology. In this paper, we review utility tree-ring data within applications four primary,...
When comprehensive and accurate data on diversity representation is available, it significantly enhances our understanding of business challenges, thereby bolstering policy decisions strategy formulation across all organizational tiers. Using the U.S. forest sector as a case study, we illustrate that there are significant gaps in within private sector, particularly terms gender race. These disparities exist various domains categories, including different industries, job roles, ownership...
Forest edges are an important legacy of natural and anthropogenic disturbances. Edges intact forest fragments influenced by adjacent non-forested ecosystems, resulting in compositional structural differences at the edge into forest. Edge influence (EI) is altered biotic abiotic interactions that occur along edge-to-interior gradient disturbed forests. Few studies have analyzed disturbance created edges, particularly woodland structures, which contain fewer trees per hectare typically less...
Montane Pinus palustris (Longleaf Pine) forests of the southeastern United States are understudied compared to Longleaf Pine Coastal Plain. In this study, we quantified composition and structure a montane stand in Weogufka State Forest Coosa County, AL. We contemporary conditions historical records describe dynamics over time. Results indicated that was dominated by Pine, followed Blackjack Oak, Chestnut Mockernut Hickory. establishment began 1750s with continuous, minimal recruitment until...
Longleaf pine ( Pinus palustris Mill.) cannot be distinguished from the other southern pines based on wood anatomy alone. A method that involves measuring pith and second annual ring diameters, reported by Arthur Koehler in 1932 (The Southern Lumberman, 145: 36–37), was revisited as an option for identifying longleaf timbers stumps. Cross-section disks of longleaf, loblolly taeda L.), shortleaf echinata were measured diameters their piths rings plotted against each other. From this plot,...
Redstone Arsenal (RA) is a large federal landholding (15,050 ha) managed by the U.S. Department of Army located on Highland Rim north Alabama. This provided unique opportunity to document forest vegetation and development patterns in region with paucity quantitative information. In this study, we quantified land cover types, delineated stands reserve using GIS, assessed composition structural measures. Stands were classed into Pinus, hardwood, mixed Pinus-hardwood, forested wetland types....
We documented the structure and composition of a Pinus palustris (Longleaf Pine) woodland community in Appalachian foothills Alabama using field measurements investigated drivers forest dynamics dendroecology paired with historical records disturbance. Longleaf Pine dominated canopy, exhibiting reverse-J–shaped diameter distribution not related age distribution. Pines dated as far back 1669 to recently early 2000s. In contrast many other forests, spatial stems our site trended toward random...
In the best-case scenario, diversity and representation data can deepen our understanding of business challenges, support policy-making strategy-setting at all levels. Using U.S. Forest sector as a case study, we illustrate that there are significant gaps in within forest sector, particularly terms gender race. These disparities manifest across various aspects including different industries, job roles, ownership structures. Our analysis brings to light inadequacies current workforce data,...
