This publication provides an overview of the forest resources in New Hampshire based upon inventories conducted by the USDA Forest Service, Forest Inventory and Analysis (FIA) program of the Northern Research Station. Information about the national and regional FIA program is available online at www.fia.fs.fed.us. Since 2002, FIA has implemented an annual inventory measuring 14 percent of sample plots each year. For the 2017 inventory, estimates for current variables, such as area, volume, and biomass, are based on 1,162 (1,047 forested) plots inventoried from 2011–2017. Change variables,...

This Resource Bulletin contains findings from a census of Wyoming’s primary forest products industry for calendar year 2014. Part I of the series presents information on the volume of timber harvested in the State by ownership, species, product, and resource area. It also describes timber flow within the State and across State lines. This effort is the fifth application of its kind in Wyoming and presents information from primary manufacturers in the State as well as facilities in surrounding States that receive timber harvested from Wyoming. Primary forest product manufacturers are firms...

This Resource Bulletin contains findings from a census of Wyoming’s primary forest products industry for calendar year 2014. Part II of the series presents information on the forest products sectors that processed timber and mill residue into finished products, including: sawmills, house log and log home manufacturers, log furniture producers, post and pole manufacturers, commercial firewood operations and wood pellets and animal bedding producers.

This Resource Bulletin presents findings from a census of Wyoming’s primary forest products manufacturers for calendar year 2014. Part III of the series presents information on sales value and employment associated with primary wood products manufacturing, the economic impact of forest products manufacturing in the State, and an analysis of the broader forest industry and how it has changed over time.

Understanding the relationship between fire intensity and fuel mass is essential information for scientists and forest managers seeking to manage forests using prescribed fires. Peak burning temperature, duration of heating, and area under the temperature profile are fire behavior metrics obtained from thermocouple-datalogger assemblies used to characterize prescribed burns. Despite their recurrent usage in prescribed burn studies, there is no simple protocol established to guide the orientation of thermocouple installation. Our results from dormant and growing season burns in coastal...

Destructive core sampling is the most recognized technique for soil bulk density estimation to monitor soil compaction. This study was conducted to determine if soil bulk density sampler size would impact value estimates and silvicultural treatment distinctions in southeastern Piedmont forest soils of the Clemson Experimental Forest, Clemson, South Carolina, USA. In 2004, six hundred soils were sampled using both an Oakfield Soil Probe (diameter 2.5 cm) and an AMS, Inc. Slide Hammer (diameter 5.1 cm). The smaller, Oakfield Soil Probe values were greater than the larger, AMS Inc. Slide...

Globally, nitrogen deposition increment has caused forest structural changes due to imbalanced plant nitrogen metabolism and subsequent carbon assimilation. Here, a 2 consecutive-year experiment was conducted to reveal the effects of canopy addition of nitrogen (CAN) on nitrogen absorption, assimilation, and allocation in leaves of three subtropical forest woody species (Castanea henryi, Ardisia quinquegona, and Blastus cochinchinensis). We hypothesized that CAN altered leaf nitrogen absorption, assimilation and partitioning of different plants in different ways in subtropical forest. It...

This publication provides an overview of the forest resources in Vermont based upon inventories conducted by the U.S. Forest Service, Forest Inventory and Analysis (FIA) program of the Northern Research Station. Information about the national and regional FIA program is available online at www.fia.fs.fed.us. Since 2003, FIA has implemented an annual inventory measuring 14 percent of sample plots each year. For the 2017 inventory, estimates for current variables, such as area, volume, and biomass, are based on 1,125 (925 forested) plots inventoried from 2011–2017. Change variables, such as...

This research explores the benefit of collaboration between the littoral countries beyond water allocation and sharing as a theoretical framework that would be a useful tool for extending Afghanistan and Pakistan cooperation for a sustainable improvement and development of the Kabul River Basin (KRB). The main goal is to highlight the concept of benefit sharing and its framework in general terms as well as in the context of KRB. The basin planning and water transboundary issues could greatly be changed in accordance with this theoretical framework, leading the game from a zero sum to a...

Trees and people both need water. With a growing global population and continued forest loss and degradation – a key question becomes: are trees and people competitors or friends? The relationship between forests, trees and water is an issue of considerable complexity and uncertainty, but of high priority for both people and the environment. In the face of such challenges, the next generation of policymakers and decision-makers will have to consider climate-forest- water-people interactions in a more holistic way. Water may be the key to unlocking policies that flow from a local understandi...
