The Fire and Fuels Extension to the Forest Vegetation Simulator

Publications Posted on: May 12, 2016
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behaviour over time, in the context of stand development and management. Existing models of fire behavior and fire effects were added to FVS to form this extension. New submodels representing snag and fuel dynamics were created to complete the linkages. This report contains four chapters.

Small mammals of the Bitterroot National Forest: Ecological significance and guidelines for management

Publications Posted on: May 12, 2016
Small mammal literature was reviewed to assess the ecological role of small mammals on the Bitterroot National Forest of western Montana. Small mammals fulfill numerous important roles in forest ecosystems by supporting a wide range of predators, dispersing seeds and mycorrhizal spores, altering vegetation through herbivory and seed predation, and preying on insects.

Soil properties in fire-consumed log burnout openings in a Missouri oak savanna

Publications Posted on: May 12, 2016
Downed logs are known to increase species diversity in many forest ecosystems by increasing resource and structural complexity and by altering fire behavior in fire-prone ecosystems. In a frequently burned oak savanna in central Missouri, combustion of downed logs formed patches that have remained free of herbaceous vegetation for more than 3 years.

A case study comparison of landfire fuel loading and emissions generation on a mixed conifer forest in northern Idaho, USA

Publications Posted on: January 21, 2016
The use of fire as a land management tool is well recognized for its ecological benefits in many natural systems. To continue to use fire while complying with air quality regulations, land managers are often tasked with modeling emissions from fire during the planning process.

Environmental drivers of deadwood dynamics in woodlands and forests

Publications Posted on: December 16, 2015
Deadwood dynamics play a key role in many forest ecosystems. Understanding the mechanisms involved in the accumulation and depletion of deadwood can enhance our understanding of fundamental processes such as carbon sequestration and disturbance regimes, allowing better predictions of future changes related to alternative management and climate scenarios.

Dynamics of coarse woody debris in southwestern mixed-conifer and ponderosa pine forests

Projects Posted on: October 09, 2015
Snags (standing dead trees) and logs are important components of forest landscapes. RMRS scientists established a series of fixed plots in 1997 for monitoring snag populations. This research has direct ramifications for 11 national forests throughout the Southwestern Region, as well as for our overall understanding of the ecology of coarse woody debris and effects of climate change on forest structure and composition.

Modeling effects of prescribed fire on wildlife habitat: Stand structure, snag recruitment and coarse woody debris

Publications Posted on: July 28, 2015
The essential role of fire in sustaining ecosystems has recently been formally recognized. It is specifically addressed in several new national policy documents. In the Federal Wildland Fire Policy and Program Review's Implementation Action Plan (US Department of Interior and U.S. Department of Agriculture 1996).

Methods for the quantification of coarse woody debris and an examination of its spatial patterning: A study from the Tenderfoot Creek Experimental Forest, MT

Publications Posted on: July 28, 2015
Methods for the quantification of coarse woody debris volume and the description of spatial patterning were studied in the Tenderfoot Creek Experimental Forest, Montana. The line transect method was found to be an accurate, unbiased estimator of down debris volume (> 10cm diameter) on 1/4 hectare fixed-area plots, when perpendicular lines were used.

Thinning effects on tree mortality and snag recruitment in western Oregon

Publications Posted on: September 30, 2013
Tree mortality shapes forest structural development and the resulting dead wood provides habitat for many species. However, the eff ects of thinning on mortality and large snag recruitment have been variable and remain poorly understood. We examined thinning eff ects on tree mortality at eleven Density Management Study (DMS) sites in western Oregon.

Pre-wildfire fuel reduction treatments result in more resilient forest structure a decade after wildfire

Publications Posted on: September 04, 2013
Increasing size and severity of wildfires have led to an interest in the effectiveness of forest fuels treatments on reducing fire severity and post-wildfire fuels. Our objective was to contrast stand structure and surface fuel loadings on treated and untreated sites within the 2002 Rodeo-Chediski Fire area.
