Effects of climate change on forested wetland soils [Chapter 9]

Publications Posted on: June 25, 2020
Wetlands are characterized by water at or near the soil surface for all or significant part of the year, are a source for food, fiber and water to society, and because of their position in landscapes and ecological structure help to moderate floods. They are also unique ecosystems with long-persistent flora and fauna.

Climate change and urban forest soils [Chapter 10]

Publications Posted on: June 25, 2020
With the proportion of the global population living in urban areas expected to reach 67% by 2040, soils located in these areas, or urban soils, will become increasingly important, particularly with regards to how these soils respond to climate change and their ability to provide ecosystem services.

On the horizon [Chapter 20]

Publications Posted on: June 25, 2020
From the outset of this book project, we wanted to address three simple questions: how are forest soils faring in our rapidly changing world? Then, how are we progressing as stewards of global soils? Finally, how can we improve our stewardship to meet the challenges of a changing world?

Long-term forest soils research: Lessons learned from the US experience [Chapter 19]

Publications Posted on: June 25, 2020
Long-term research studies are critical to understanding soil productivity and the sustainability of forest and woodland ecosystems around the world. They inform management decisions about best harvest techniques, soil property impacts and recovery, anthropogenic stressors (e.g., forest management, acid rain, climate change), and the influence if governmental policies, guidelines, and regulations.

Fuels planning: science synthesis and integration; environmental consequences fact sheet 14: Fuels reduction and compaction

Publications Posted on: June 22, 2020
Moving equipment and logs over the surface of forest soils causes gouges and ruts in the mineral soil, displaces organic matter, and can cause compaction. Compaction is the component of soil productivity most influenced by forest management, but the degree to which soils may be compacted depends on initial soil bulk density.

Microdensitometry to identify plant communities and components on color infrared aerial photos

Publications Posted on: January 22, 2020
Image density differences in color infrared aerial photos can be used to discriminate individual shrub and tree species of a pinyon pine-juniper plant community. In addition, image density was used successfully to identify six general plant communities: ponderosa pine, spruce-fir, aspen, big sagebrush, native grasslands, and seeded grasslands.

Biochar amendments to forest soils: Effects on soil properties and tree growth

Documents and Media Posted on: December 20, 2018
Bioenergy production from forest biomass offers a unique solution to reduce wildfire hazard fuel while producing a useful source of renewable energy. However, biomass removals raise concerns about reducing soil carbon (C) and altering forest site productivity.Document Type: Other Documents

Effects of mechanical site preparation on selected physical properties of four volcanic ash influenced forest soils in Northern Idaho

Documents and Media Posted on: December 20, 2018
Mechanical site preparation and its effects were studied on four volcanic ash influenced forest soils. Changes in bulk density, soil porosity, moisture characteristics, and volcanic ash thickness were evaluated at three slash disposal and one brush disposal site. Document Type: Other Documents

Fuel: Logs, sticks, needles, duff, and much more

Publications Posted on: March 27, 2018
Fuels burned by either prescribed or wildfires are complex and important components of forested ecosystems. Fine fuels consisting of fallen limbs, twigs, and leaves of shrubs and trees are rich in nutrients. If these fuels are not immediately burned, nutrients can leach from these materials into the forest floor, especially if they overwinter.

Opportunities and uses of biochar on forest sites in North America [Chapter 15]

Publications Posted on: June 08, 2017
Biochar may be useful for restoring or revitalizing degraded forest soils and help with carbon sequestration, nutrient leaching losses, and reducing greenhouse gas emissions. However, biochar is not currently widely used on forested lands across North America.
