Using FIA data to predict forest understory vegetation structure

Science Spotlights Posted on: September 03, 2019
Understanding the structure of understory vegetation in forests is critical for estimating carbon stocks, fuel loading, and assessing wildlife habit. Using nationally collected inventory data shows promise in providing better estimates and assessments in these areas over large geographical regions.

Predicting understory vegetation structure in selected western forests of the United States using FIA inventory data

Publications Posted on: July 25, 2019
Understory vegetation structure and its relationship with forest canopies and site conditions are important determinants of carbon stocks, wildlife habitat, and fuel loading for wildland fire assessments. Comprehensive studies are needed to assess these relationships through the use of consistently collected field-based data.

Post-spruce beetle timber salvage drives short-term surface fuel increases and understory vegetation shifts

Publications Posted on: February 21, 2019
Recent, widespread spruce beetle (Dendroctonus rufipennis) outbreaks have driven extensive tree mortality across western North America. Post-disturbance forest management often includes salvage logging to capture economic value of dead timber, reduce fire hazard, and meet other social or ecological objectives.

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.

Characteristics of mixed-oak forest ecosystems in southern Ohio prior to the reintroduction of fire

Publications Posted on: May 12, 2016
Contains 12 chapters describing baseline conditions of mixed-oak forest ecosystems in the context of a long-term study of prescribed fire effects.

Post-fire logging produces minimal persistent impacts on understory vegetation in northeastern Oregon, USA

Publications Posted on: April 21, 2016
Post-fire forest management commonly requires accepting some negative ecological impacts from management activities in order to achieve management objectives. Managers need to know, however, whether ecological impacts from post-fire management activities are transient or cause long-term ecosystem degradation.

Beaver Creek Experimental Watershed: Research on fuel treatment effects

Projects Posted on: January 04, 2016
In the mid-2000's researchers reinstated research at Beaver Creek Experimental Watershed (BCEW) to collect data on climate, stream flow, vegetation, forest floor, and soil conditions. The Southwest Watershed Science Team and Northern Arizona University are exploring the effects of fuel treatments on stream flow, vegetation, forest floor, and soil conditions at the BCEW. The main goal of ongoing research is to provide land managers with information about the ecological effects of fuel treatments in the ponderosa pine forests and pinyon-juniper woodlands at a watershed scale.

Understory recovery in harvested ponderosa pine forests on the Black Hills National Forest

Media Gallery Posted on: April 22, 2015
Scientists with the Rocky Mountain Research Station and university partners are investigating the short- and long-term resiliency of understory vegetation of ponderosa pine forests to a variety disturbances associated with timber harvest.

Understory vegetation following the 2002 Hayman Fire in Colorado (2003-2015)

Projects Posted on: April 14, 2015
Many of today’s fires in ponderosa pine dominated forests are burning more severely than historical ones, generating concern that understory plant communities will not recover without intervention.  There are also concerns that fires will facilitate the establishment and spread of non-native species.  In 2002, Colorado’s Hayman Fire burned pre-existing understory vegetation plots and provided an opportunity to address these concerns. 

Short-term responses of overstory and understory vegetation to thinning treatments: a tale of two studies

Publications Posted on: September 30, 2013
The Density Management Study and Young Stand Th inning and Diversity Study were initiated to investigate whether alternative thinning treatments can accelerate the development of forests toward late-successional structures. An overview of overstory and understory vegetation responses indicates that the magnitude and direction of thinning eff ects initially varied among structural stand components.
