Research Highlights
Using New Technologies to Improve Log Defect Detection
Year: 2016
Scientists from the Forest Service’s Forest Products Laboratory and Northern Research Station cooperated with West Virginia University to enhance the competitiveness of the U.S. hardwood lumber industry by improving the accuracy of log internal defect detection and maximizing log value recovery.
Effects of Silviculture Practices on the Engineering Properties of Northern Hardwood Species of the Lake States
Year: 2018
Wood quality is an important determinant of its end use and therefore its value. Recent proliferation of novel engineered wood products has created new potential uses for hardwood. However, a greater understanding of wood quality is needed to allow continued development of these novel wood products.
Bonding Mixed Species for Advanced Biomaterials
Year: 2018
Massive composite timbers, such as cross laminated timber (CLT), are essential for tall timber buildings that require use of locally available wood resources to reduce manufacturing costs and minimize environmental impacts. This opens a potential sustainable market for undervalued hardwood forest fe...
Nondestructive Assessment of Wood Members in a Viewing Tower in Potawatomi State Park, Door County, Wisconsin, USA
Year: 2019
USDA Forest Service scientists assessed the condition of a historic observation tower to determine if it could be enjoyed safely.
Heat Sterilization of Firewood for Thermal Eradication of Emerald Ash Borer
Year: 2010
FPL researchers have led a joint research effort with USDA APHIS and state regulatory staff to evaluate various heat treatment options and heating times for ash firewood and help firewood industry to successfully implement the heat treatment process as required by the new USDA phytosanitary regulati...
Develop thermal verification guidelines for firewood heat treatment
Year: 2011
To stop further spread of the Emerald Ash Borer (EAB), the USDA Animal and Plant Health Inspection Service (APHIS) has enforced a heat treatment process for the U.S. firewood industry to heat sterilize all hardwood firewood before it can be shipped out of infested areas. Yet, many firewood producers...
New Acoustic Technology Evaluates Wood Quality of Standing Trees
Year: 2013
Lack of techniques to assess the quality of standing trees results in inefficient allocation of timber resources and also limits the ability of forest managers to grow high-quality wood with appropriate silvicultural treatments. To address the problem, Forest Products Laboratory researchers and thei...
