Numerical modeling of coupled water flow and heat transport in soil and snow

Publications Posted on: August 18, 2016
A one-dimensional vertical numerical model for coupled water flow and heat transport in soil and snow was modified to include all three phases of water: vapor, liquid, and ice. The top boundary condition in the model is driven by incoming precipitation and the surface energy balance.

Data for National Fire and Fire Surrogate study: environmental effects of alternative fuel reduction treatments

Datasets Posted on: June 08, 2016
Comprised of 12 sites nationwide, the Fire and Fire Surrogates study (FFS) is a comprehensive interdisciplinary experiment designed to evaluate the economics and ecological consequences of alternative fuel reduction treatments in seasonally dry forests of the United States.

Long-term soil changes from forest harvesting and residue management in the northern Rocky Mountains

Publications Posted on: June 07, 2016
Soil changes associated with forest harvesting, differing utilization levels, and post-harvest prescribed burning were determined using an empirical study to investigate the long-term impacts on soil physical and chemical properties at Coram Experimental Forest in northwestern Montana. In 1974, two replications of three regeneration cuttings (shelterwood, group selection, and clearcut) were installed.

Seed and soil dynamics in shrubland ecosystems: proceedings; 2002 August 12-16; Laramie, WY

Publications Posted on: May 12, 2016
The 38 papers in this proceedings are divided into six sections; the first includes an overview paper and documentation of the first Shrub Research Consortium Distinguished Service Award. The next four sections cluster papers on restoration and revegetation, soil and microsite requirements, germination and establishment of desired species, and community ecology of shrubland systems.

Wildland fire in ecosystems: effects of fire on soils and water

Publications Posted on: May 12, 2016
This state-of-knowledge review about the effects of fire on soils and water can assist land and fire managers with information on the physical, chemical, and biological effects of fire needed to successfully conduct ecosystem management, and effectively inform others about the role and impacts of wildland fire.

Forest vegetation and soil patterns across glade-forest ecotones in the Knobs region of northeastern Kentucky, USA

Publications Posted on: April 23, 2016
The Crooked Creek Barrens Preserve in the northeastern Knobs region of Kentucky contains an aggregation of species-rich grass and forb-dominated glade openings surrounded by secondary forest. Encroachment of woody species and invasion by non-native species threaten the rare forbs and sedges of the glades.

GSD Update: Year in Review: Spotlight on 2015 Research by the Grassland, Shrubland and Desert Ecosystems Science Program

Publications Posted on: March 23, 2016
In this issue of the GSD Update, we take a look back at selected studies of the Grassland, Shrubland and Desert Ecosystems Science Program (GSD) that depict its strengths and focus areas. Significant results of recent research and science delivery by GSD scientists are highlighted. We feature program research that lines up with the strategic research priorities of the USDA Forest Service and the Rocky Mountain Research Station (RMRS).

Mastication effects on fuels, plants, and soils in four western U.S. ecosystems

Documents and Media Posted on: January 29, 2016
This project compared fuel reduction mulching and adjacent untreated stands at conifer ecosystems distributed across Colorado and evaluated the effects of mulch depth both experimentally and in operational units. Results from this study provide land managers and researchers greater understanding of the lasting effects of mulching on community and ecosystem processes. Document Type: Other Documents

Soils [Chapter 4.2]

Publications Posted on: October 07, 2015
Soils are crucial for profitable and sustainable biomass feedstock production. They provide nutrients and water, give support for plants, and provide habitat for enormous numbers of biota. There are several systems for soil classification. FAO has provided a generic classification system that was used for a global soil map (Bot et al., 2000).

Rapid response tools and datasets for post-fire modeling: Linking Earth Observations and process-based hydrological models to support post-fire remediation

Publications Posted on: October 05, 2015
Preparation is key to utilizing Earth Observations and process-based models to support post-wildfire mitigation. Post-fire flooding and erosion can pose a serious threat to life, property and municipal water supplies. Increased runoff and sediment delivery due to the loss of surface cover and fire-induced changes in soil properties are of great concern.
