Applications of the United States Forest Inventory and Analysis dataset: A review and future directions

Publications Posted on: November 19, 2018
The United States Forest Inventory and Analysis (FIA) program has been monitoring national forest resources in the United States for over 80 years; presented here is a synthesis of research applications for FIA data. A review of over 180 publications that directly utilize FIA data is broken down into broad categories of application and further organized by methodologies and niche research areas.

The legacy of severe wildfire on stream water quality

FS News Posted on: September 25, 2018
Do severe wildfires impact rivers and reservoirs years after they burn? In Colorado, at the site of the 2002 Hayman Fire, a new study found that watersheds with extensive high-severity wildfire still contained elevated levels of streamwater nitrogen. While elevated nitrogen and carbon in burned watersheds are not a threat to drinking water quality, they do exceed expected levels for healthy streams in this area. 

Carbon to organic matter ratios for soils in Rocky Mountain coniferous forests

Publications Posted on: April 23, 2018
Vegetation type, soils, climate, and conversion ratios influence estimates of terrestrial C.

Loss of aboveground forest biomass and landscape biomass variability in Missouri, US

Publications Posted on: March 28, 2018
Disturbance regimes and forests have changed over time in the eastern United States. We examined effects of historical disturbance (circa 1813 to 1850) compared to current disturbance (circa 2004 to 2008) on aboveground, live tree biomass (for trees with diameters ≥13 cm) and landscape variation of biomass in forests of the Ozarks and Plains landscapes in Missouri, USA.

Daily black carbon emissions data from fires in Northern Eurasia for 2002–2015

Datasets Posted on: March 15, 2018
This data publication, the Fire Emission Inventory – Northern Eurasia (FEI-NE), consists of a high spatial resolution (500 meter × 500 meter) dataset of daily black carbon (BC) emissions from forest, grassland, shrubland, and savanna fires in Northern Eurasia from 2002 to 2015.

Missoula Fire Lab Emission Inventory (MFLEI) for CONUS

Datasets Posted on: March 15, 2018
The Missoula Fire Lab Emission Inventory (MFLEI) is a retrospective, daily wildfire emission inventory for the contiguous United States with a spatial resolution of 250 meters (m). MFLEI was produced using multiple datasets of fire activity and burned area, a newly developed wildland fuels map and an updated emission factor database.

Data and source code for "A Bayesian model to correct underestimated 3D wind speeds from sonic anemometers increases turbulent components of the surface energy balance"

Datasets Posted on: March 15, 2018
Sonic anemometers are the principal instruments in micrometeorological studies of turbulence and ecosystem fluxes. Common designs underestimate vertical wind measurements because they lack a correction for transducer shadowing, with no consensus on a suitable correction. We present a subset of data collected during field experiments in 2011 and 2013 featuring two or four CSAT3 sonic anemometers.

Characteristics of masticated particles in mixed-conifer forests of the western United States: Chemistry, heat content, and mineral percentage results

Datasets Posted on: March 15, 2018
This data publication contains the results of chemical and mineral analyses on masticated particles from mixed-conifer forests in 15 study locations. These data were collected from 2012 through 2016 as part of the MASTIDON project.

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. 

Root disease can rival fire and harvest in reducing forest carbon storage

Publications Posted on: September 27, 2017
Root diseases are known to suppress forest regeneration and reduce growth rates, and they may become more common as susceptible tree species become maladapted in parts of their historic ranges due to climate change.
