Fire effects on herbaceous regeneration across an invasion gradient in grasslands and shrublands

Projects Posted on: November 02, 2018
Post-fire resiliency of plant communities in northern mixed-grass prairie and eastern sagebrush steppe depends largely on plant regeneration from aboveground and belowground buds. Canopy and stem regeneration occurs more quickly via the bud bank than via seedling recruitment. To better predict plant community responses to fire, we need an enhanced understanding of the immediate and long-term bud responses of key forb, grass, and shrub species to fire.

Daily black carbon emissions from fires in northern Eurasia for 2002-2015

Publications Posted on: October 05, 2018
Black carbon (BC) emitted from fires in northern Eurasia is transported and deposited on ice and snow in the Arctic and can accelerate its melting during certain times of the year. Thus, we developed a high spatial resolution (500m x 500 m) dataset to examine daily BC emissions from fires in this region for 2002-2015.

Is increased precipitation during the 20th century statistically or ecologically significant in the eastern US?

Publications Posted on: September 26, 2018
We address the climate versus disturbance debate to understand drivers of change in human-environment systems. We examine whether recent increased precipitation episodes (‘pluvials’) are unique and have ecological implications for the humid climate of the eastern United States. Robust statistical analyzes presented here indicate that the 20th century was wet, but not significantly different than other centuries during the last millennium.

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. 

An update of the National Fire Danger Rating System

Science Spotlights Posted on: September 13, 2018
The National Fire Danger Rating System (NFDRS) is a system that allows fire managers to estimate today's or tomorrow's fire danger for a given area. In 2014, RMRS fire danger rating system developers sought and gained approval to update the U.S. National Fire Danger Rating System (NFDRS).

Environmental, structural, and disturbance influences over forest floor components in interior Douglas-fir forests of the Intermountain West, USA

Publications Posted on: August 21, 2018
Downed woody material (DWM) is a key component in forest ecosystems with age, structure, and disturbance described as primary factors that influence DWM dynamics. In particular, much emphasis is placed on large coarse woody debris (CWD).

Recalling open old growth forests in the Southeastern Mixed Forest province of the United States

Publications Posted on: August 20, 2018
Historical forests in the Southeastern Mixed Forest province of the United States have been less researched than other regions using historical tree surveys. We used 81,000 tree records from surveys during the 1800s to quantify composition of this ecological province. Upland oaks and pines comprised about 75% of all trees, with relatively equal composition.

A site-specific approach for assessing the fire risk to structures at the wildland/urban interface

Publications Posted on: August 01, 2018
The essence of the wildland/urban interface fire problem is the loss of homes. The problem is not new, but is becoming increasingly important as more homes with inadequate adherence to safety codes are built at the wildland/urban interface. Current regulatory codes are inflexible. Specifications for building and site characteristics cannot be adjusted to accommodate homeowner values.

Fuels planning: science synthesis and integration; social issues fact sheet 07: The "laws" of effective public education about fire hazards

Publications Posted on: August 01, 2018
Within the past 10 years, breakthrough research has identified factors that are most important for effectively communicating about wildland fire hazards. This fact sheet discusses seven "Laws" of effective public communication that should be considered in any state-of-the-art education campaign. Other publications in this series
