A reconceptualization of open oak and pine ecosystems of eastern North America using a forest structure spectrum

Publications Posted on: November 15, 2018
We present a reconceptualization of forests in eastern North America by differentiating the ecological characteristics of open oak (Quercus) and pine (Pinus) forests from closed successional and oldgrowth forests. Despite historical abundance of savannas and woodlands, the fundamental ecology of open forest ecosystems remains ill-defined when compared to either closed forests or grasslands.

Management and succession at the Lick Creek Demonstration/Research Forest, Montana

Publications Posted on: August 30, 2018
The Lick Creek Demonstration/Research Forest is one of those places in the West that many foresters may not be familiar with by name but by photographs. Posters depicting forest change over the years circulated widely from the 1980s to 2000s, following Forest Service General Technical Reports from Gruell et al. (1982) and Smith and Arno (1999).

Shrub cover and fire history predict seed bank composition in Great Basin shrublands

Publications Posted on: August 17, 2018
Dormant seeds in the soil are an important contribution to the regenerative potential of an area. Understanding factors that affect seed bank dynamics in arid regions provides insight into how communities respond to disturbance and environmental change.

Fortifying the forest: Thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience

Publications Posted on: September 30, 2016
Fire frequency in low-elevation coniferous forests in western North America has greatly declined since the late 1800s. In many areas, this has increased tree density and the proportion of shade-tolerant species, reduced resource availability, and increased forest susceptibility to forest insect pests and high-severity wildfire.

FireWorks curriculum featuring ponderosa, lodgepole, and whitebark pine forests

Publications Posted on: May 12, 2016
FireWorks is an educational program for students in grades 1-10. The program consists of the curriculum in this report and a trunk of laboratory materials, specimens, and reference materials. It provides interactive, hands-on activities for studying fire ecology, fire behavior, and the influences of people on three fire-dependent forest types - Pinus ponderosa (ponderosa pine), Pinus contorta var.

User's Guide to Version 2 of The Regeneration Establishment Model: Part of The Prognosis Model

Publications Posted on: May 12, 2016
This publication describes how to use version 2 of the Regeneration Establishment Model, a computer-based simulator that is part of the Prognosis Model for Stand Development. Conifer regeneration is predicted following harvest and site preparation for forests in western Montana, central Idaho, and northern Idaho.

Wildland fire in ecosystems: effects of fire on flora

Publications Posted on: May 12, 2016
VOLUME 2: This state-of-knowledge review about the effects of fire on flora and fuels can assist land managers with ecosystem and fire management planning and in their efforts to inform others about the ecological role of fire.

Wildland fire in ecosystems: effects of fire on fauna

Publications Posted on: May 12, 2016
VOLUME 1: Fires affect animals mainly through effects on their habitat. Fires often cause short-term increases in wildlife foods that contribute to increases in populations of some animals. These increases are moderated by the animals' ability to thrive in the altered, often simplified, structure of the postfire environment.

Definitions and codes for seral status and structure of vegetation.

Publications Posted on: May 12, 2016
Definitions and codes for identifying vegetation seral status and structure are desired for land management planning, appraising wildlife habitat, and prescribing vegetation treatment. Codes are only presented; they are not a system for determining seral status or stand structure.

Celebrating 30 years of the Fire Effects Information System (FEIS)

Science Spotlights Posted on: November 10, 2015
Thirty years ago, Rocky Mountain Research Station scientist William (Bill) Fischer proposed a highly innovative computer system to provide managers with information about the effects of prescribed fire. Technology has changed radically since Fischer originally envisioned a computer program to provide fire effects information electronically. The FEIS user interface now enables readers to search using many criteria, including maps, and it connects information from all three FEIS products - Species Reviews, Fire Studies, and Fire Regimes.
