Connecting soils with forest productivity

Documents and Media Posted on: October 10, 2018
The productivity of Rocky Mountain forests is lower than forests in most other regions due to shorter growing seasons and low precipitation. Nutrient availability also appears to limit most forests in the region.Document Type: Other Documents

Vegetation control by steam treatment in boreal forests: a comparison with burning and soil scarification

Documents and Media Posted on: October 03, 2018
The Vaccinium myrtillus L. - feather moss vegetation community immobilizes nutrients in surface organic layers and suppresses growth of coniferous seedlings in northern boreal forests. On a site dominated by this type of vegetation, a new site preparation technique, involving steam treatment to kill ground vegetation, was tested and compared with conventional site preparation techniques such as soil scarification and burning.Document Type: Other Documents

Soil organic matter in a ponderosa pine forest with varying seasons and intervals of prescribed burn

Documents and Media Posted on: October 03, 2018
Prescribed burning is used to reduce fuel loads and return ponderosa pine forests of the Western U.S. to their historical structure and function. The impact of prescribed burning on soil is dependent on fire severity which is largely managed by burning in the fall or the spring; frequency of fire will also regulate long-term fire impacts.Document Type: Other Documents

Effect of timber harvesting on microbial biomass fluxes in a northern Rocky Mountain forest soil

Documents and Media Posted on: October 03, 2018
Microbial biomass and relative bacterial and fungal percentages were measured in organic forest soil from a Rocky Mountain site subjected to four harvesting treatments: RL, clear-cut and residue left; RR, clear-cut and residue removed; RB, clear-cut and residue burned; C, uncut control. Microbial biomass peaked in spring and fall regardless of treatment.Document Type: Other Documents

Response of western larch to site preparation

Publications Posted on: May 11, 2018
Western larch (Larix occidentalis Nutt.) regenerates and grows adequately on a variety of soils and sites. Mineral soil and burned-over surfaces are excellent for natural regeneration, but organic surfaces also provide adequate seedbeds. Planted western larch are aggressive root producers especially in moist soils. Best development occurs in soils with high organic matter content. Competing vegetation often reduces performance.

Coram Experimental Forest daily meteorology data for Desert Ridge and Terrace Hills weather stations: 1996-2015

Datasets Posted on: March 15, 2018
This data publication contains daily meteorological data collected at the Desert Ridge and Terrace Hills weather stations located on the Coram Experimental Forest (Flathead National Forest) in Montana. The Terrace Hills weather station was installed in May of 1996, and the Desert Ridge weather station was installed in May of 2001. Data are included up through 2015 for both stations.

Estimating carbon and nitrogen pools in forest soil: Influence of soil bulk density methods and rock content

Science Spotlights Posted on: February 01, 2018
Many U.S. forests contain soils with high rock content, and quantities of stored carbon and nitrogen. There is a need to calculate changes in carbon and nutrient pools in soils, but current sampling methods are not completely reliable in rocky soils. Managers and climate change researchers are using estimates of carbon pools to indicate soil productivity, alteration of biological activity, impacts from fire, or carbon storage potential. 

Air, soil, and water resources and quality

Pages Posted on: February 06, 2017
Air, soil, and water resources and quality provide the foundation for ecosystems and ecosystem services. These publications and tools include valuable information in these areas, including spatial modeling tools and publications specific to certain regions.

Redistribution of pyrogenic carbon from hillslopes to stream corridors following a large montane wildfire

Publications Posted on: January 30, 2017
Pyrogenic carbon (PyC) constitutes a significant fraction of organic carbon in most soils. However, PyC soil stocks are generally smaller than what is expected from estimates of PyC produced from fire and decomposition losses, implying that other processes cause PyC loss from soils. Surface erosion has been previously suggested as one such process.
