How much soil disturbance can be expected as a result of southern pine beetle suppression activities?

Publications Posted on: September 05, 2019
Land managers have long recognized the importance of maintaining soil productivity in the context of sustainable forest management. Soil disturbance that results in impaired hydrologic function and changes in certain soil properties (e.g., structure, organic matter) may be detrimental to soil productivity.

Southern pine beetle effects on soil disturbance

Science Spotlights Posted on: August 21, 2019
Land managers recognize that maintaining soil health during harvest operations is important for ensuring hydrologic function, nutrient cycling, vegetative regrowth, and stable carbon reserves. However, during salvage logging operations many of these values may be at risk because of soil disturbance associated with equipment movement on a site. Communicating with specialists about the importance of maintaining soil quality resulted in very little disturbance in 37 harvest units across Mississippi.

What 22 years of monitoring reveals about forest soil resiliency

Science Spotlights Posted on: November 19, 2018
Since the 1980s, it’s been assumed that forest soils require a long time to recover from a disturbance such as a timber harvest. The results of a 22-year monitoring study on the Kootenai National Forest counter this assumption. Certain types of forest soils showed a recovery within five to seven years following a timber harvest and subsequent fuels treatments.

Soil moisture reduces belowground heat flux and soil temperatures under a burning fuel pile

Documents and Media Posted on: October 03, 2018
A direct comparison of temperatures and heat loads was made between simulated duff-covered (~2 cm) and uncovered mineral soil beneath a burning fuel pile. Temperatures were recorded in the duff, at the duff-mineral soil interface, and at 1-cm intervals downward to a depth of 4 cm. Covering reduced the peak temperatures about 200oC in dry mineral soil.Document Type: Other Documents

Soil survey of Kootenai National Forest area, Montana and Idaho

Documents and Media Posted on: August 29, 2018
This soil survey contains information that can be used in land-planning programs in the survey area. The landforms, natural vegetation, and bedrock were studied to a greater extent than usual in soil surveys in order to define and interpret map units.Document Type: Other Documents

Soil disturbance recovery on the Kootenai National Forest, Montana

Publications Posted on: August 15, 2018
Determining the extent of soil property changes following forest management activities (e.g., timber harvest, fuels abatement, site preparation) is an ongoing concern for land managers. Monitoring the long-term effects of various harvest operations and fuels treatment methods on soil physical properties and hydrologic function is critical to maintaining forest productivity.

Impacts of forest harvest on active carbon and microbial properties of a volcanic ash cap soil in northern Idaho

Publications Posted on: April 17, 2015
Soil quality assessments are essential for determining impacts on belowground microbial community structure and function. We evaluated the suitability of active carbon (C), a rapid field test, as an indicator of soil biological quality in five paired forest stands (clear cut harvested 40 years prior and unharvested) growing on volcanic ash-cap soils in northern Idaho.

Soil Quality Standards Monitoring Program administration and implementation

Publications Posted on: July 26, 2010
Forest managers and resource scientists and specialists are engaged in a partnership to sustain the natural resource value of our national forests. Managers are faced with deciding which activities provide the best resource benefits with the least resource damage. Many, but not all, aspects of the decision process must be based on the science supporting our current understanding of natural resources.

Statistical sampling methods for soils monitoring

Publications Posted on: July 26, 2010
Development of the best sampling design to answer a research question should be an interactive venture between the land manager or researcher and statisticians, and is the result of answering various questions.
