Sediment production from forest roads in western Oregon

Publications Posted on: January 12, 2016
Prevention and estimation of soil erosion from forest roads requires an understanding of how road design and maintenance affect sediment production. Seventy-four plots were installed on forest roads in the Oregon Coast Range to examine the relationship between sediment production and road attributes such as distance between culverts, road slope, soil texture, and cutslope height.

Research related to roads in USDA experimental forests [Chapter 16]

Publications Posted on: March 17, 2015
Forest roads are essential in experimental forests and rangelands (EFRs) to allow researchers and the public access to research sites and for fire suppression, timber extraction, and fuel management. Sediment from roads can adversely impact watershed health. Since the 1930s, the design and management of forest roads has addressed both access issues and watershed health.

Forest Service Water Erosion Prediction Project (FS WEPP)

Projects Posted on: January 23, 2015
The Air, Water and Aquatic Environments Science Program has developed a suite of internet interfaces, the Forest Service Water Erosion Prediction Project (FS WEPP), designed to allow users to quickly evaluate erosion and sediment delivery potential from forest roads.

Sediment delivery in a changing climate

Documents and Media Posted on: January 23, 2015
The delivery and transport of sediment through mountain rivers affects aquatic habitat and water resource infrastructure. While climate change is widely expected to produce significant changes in hydrology and stream temperature, the effects of climate change on sediment yield have received less attention.Document Type: Briefing Papers

Road decommissioning: picking the right road

Documents and Media Posted on: January 23, 2015
There are many miles of roads in our National Forests, many of them old and untended. Many examples exist where abandoned older roads fail and divert water from streams over hillsides, destroying downstream infrastructure and fish habitat. When resources are limited, and when visitors to the National Forests value road access, being choosy about where to do work and what kind of work to do is important.Document Type: Briefing Papers

Geomorphic road analysis and inventory package (GRAIP)

Documents and Media Posted on: January 23, 2015
Forest roads are a principle source of anthropogenic fine sediment entering streams on Forest Service lands. Efficiently locating, quantifying, and prioritizing reduction activities for these sediment sources is a major concern for managers.   GRAIP Identifies: 1) sediment delivery from roads to streams;Document Type: Briefing Papers

Water Erosion Prediction Project (WEPP)

Tools Posted on: August 05, 2014
FS WEPP is a set of interfaces designed to allow users to quickly evaluate erosion and sediment delivery potential from forest roads. The erosion rates and sediment delivery are predicted by the Water Erosion Prediction Project (WEPP) model, using input values for forest conditions.

Response of nesting northern goshawks to logging truck noise in northern Arizona

Publications Posted on: October 23, 2013
We recorded 94 sound-response events at 3 adult-occupied northern goshawk (Accipiter gentilis) nests 78 m, 143 m, and 167m from the nearest United States Forest Service maintenance level 3, improved gravel road on the Kaibab Plateau in northern Arizona.

Erosion processes and prediction with WEPP technology in forests in the Northwestern U.S.

Publications Posted on: June 28, 2013
In the northwestern U.S., the greatest amounts of forest erosion usually follow infrequent wildfires. Sediment from these fires is gradually routed through the stream system. The forest road network is usually the second greatest source of sediment, generating sediment annually. Erosion rates associated with timber harvest, biomass removal, and prescribed fire are generally minimal with current management practices.
