This resource update is a brief look at some of the basic metrics that describe the status of and changes to forest resources in Vermont. This information is based on field data collected using the USDA Forest Service Forest Inventory and Analysis (FIA) annualized sample design, and it is updated yearly. Tables for Forests of Vermont, 2021 can be found at https://doi.org/10.2737/FS-RU-373-Tables.

Cycling of carbon (C), nitrogen (N), calcium (Ca), phosphorus (P), and sulfur (S) is an important ecosystem service that forest soils provide. Humans influence these biogeochemical processes through the deposition of atmospheric pollutants and site disturbances. One way to study these potential anthropogenic trajectories is through long-term monitoring in association with human-caused environmental gradients such as urban-rural gradients. The objective of this study was to characterize changes in surface soil chemistry of urban, suburban and rural forest patches in the Baltimore Metropolita...

Active forest management is applied in many parts of the western United States to reduce wildfire severity, mitigate vulnerability to drought and bark beetle mortality, and more recently, to increase snow retention and late-season streamflow. A rapidly warming climate accelerates the need for these restorative treatments, but the treatment priority among forest patches varies considerably. We simulated four treatment scenarios across the 3,450 km2 Wenatchee River basin in eastern Washington, United States. We used a decision support tool (DST) to assess trade-offs and synergies within and...

Forest biological disturbance agents (BDAs) are insects, pathogens, and parasitic plants that affect tree decline, mortality, and forest ecosystems processes. BDAs are commonly thought to increase the likelihood and severity of fire by converting live standing trees to more flammable, dead and downed fuel. However, recent research indicates that BDAs do not necessarily increase, and can reduce, the likelihood or severity of fire. This has led to confusion regarding the role of BDAs in influencing fuels and fire in fire-prone western United States forests. Here, we review the existing...

In contemporary forest landscapes, aquatic-riparian management approaches are addressing ecological integrity of site-to-landscape components that extend beyond the reach of traditional best management practices (BMPs). In this chapter, we highlight the intersection of BMPs that have guided past priorities with integrated interdisciplinary geomorphic, hydrologic, and biological perspectives of joint aquatic-terrestrial ecosystem management and restoration in forests. Beyond-BMP considerations include adapting prescribed BMPs for broader species and habitat protections and recognizing the...

This study assesses the impacts of whole-tree harvesting (WTH) versus stem-only harvest (SOH) on two oak-dominated stands located in Northern Wisconsin. Specifically, our study follows up on an experiment designed to better understand the impacts of WTH and whether stands are at risk of long-term nutrient losses, which could contribute to declines in productivity. The original study assessed: (i) full biomass removal (referred to as WTH), (ii) partial biomass removal (removal to 5 cm diameter bole), (iii) a traditional SOH (removal to 10 cm bole), and (iv) no harvest (control). Our data...

Uneven-aged silviculture is becoming increasingly popular as a tool to restore and manage forests for multiple benefits. However, there are few studies that evaluate the growth response of shade intolerant pine species in the southeastern United States to regeneration harvests during stand conversion process. We utilized an existing long-term, operational scale, replicated stand conversion trial in the southeastern United States to evaluate the effects of two initial stand conversion harvest treatments (uniform shelterwood and group cuttings) and an uncut control on the growth of residual...

The brown rot fungus Fomitopsis pinicola efficiently depolymerizes wood cellulose via the combined activities of oxidative and hydrolytic enzymes. Mass spectrometric analyses of culture filtrates identified specific proteins, many of which were differentially regulated in response to substrate composition.
