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.

Comparisons between wildfire and forest harvesting and their implications in forest management

Documents and Media Posted on: October 03, 2018
Emulation silviculture is the use of silvicultural techniques that try to imitate natural disturbances such as wildfire. Emulation silviculture is becoming increasingly popular in Canada because it may help circumvent the political and environmental difficulties associated with intensive forest harvesting practices. In this review we summarize empirical evidence that illustrates disparities between forest harvesting and wildfire.Document Type: Other Documents

Mass of downed wood in northern hardwood forests in New Hampshire: Potential effects of forest management

Documents and Media Posted on: October 03, 2018
Downed (i.e., fallen, dead) wood was sampled in 1-, 15-, 50-, and 100-year-old managed stands, an uneven-aged, managed stand, and an uncut stand of northern hardwoods in New Hampshire. Mass of downed wood ranged from a mean of 32 t/ha in the 15-and 50-year-old stands to 86 t/ha in the recently cut stand.Document Type: Other Documents

Managing forests and forest carnivores: Canada lynx and forest mosaics

Science Spotlights Posted on: September 07, 2018
The management of Canada lynx habitat is an issue that has generated much debate and litigation across the Northern (Montana, Idaho) and Southern (Colorado, Wyoming) Rocky Mountains. This species depends almost exclusively on snowshoe hare for food during winter, and this prey species is sensitive to changes in forest composition and structure. Research conducted by scientists at the Rocky Mountain Research Station, in collaboration with universities and local forest managers, is central in resolving management impasses by learning how changes in forest structure and composition can be implemented in ways that enhance the ability of Canada lynx to produce kittens.  

Modeling decay of woody residues helps managers understand forest growth

Science Spotlights Posted on: September 05, 2018
Maintaining woody debris on forest sites is critical for maintaining carbon stores and modeling the rate of decay helps managers understand tree growth and and carbon sequestration.

The big picture on whitebark pine

FS News Posted on: August 31, 2018
Throughout the western United States, whitebark pine is experiencing high mortality, leading to concern about long-term viability of whitebark pine and other species that depend on it. Two new studies of whitebark pine in the western U.S. show that this species continues to die-off in alarming numbers and identifies locations where forest managers may be able to encourage growth of young whitebark pines.

Effect of firewood harvesting on birds in a California oak-pine woodland

Publications Posted on: August 01, 2018
Despite a history of oak clearing and thinning in California, little is known about the effects of firewood harvesting on wildlife in oak woodlands. We studied the effect of firewood harvesting on population trends of birds during the breeding season in an oak-pine woodland in the foothills of the northern Sierra Nevada, California.

Supplement to The User's Guide for The Stand Prognosis Model-version 5.0

Publications Posted on: August 01, 2018
Differences between Prognosis Model versions 4.0 and 5.0 are described. Additions to version 5.0 include an event monitor that schedules activities contingent on stand characteristics, a regeneration establishment model that predicts the structure of the regeneration stand following treatment, and a COVER model that predicts shrub development and total canopy cover.

Assessing the effects of fire disturbance and timber management on carbon storage in the Greater Yellowstone Ecosystem

Publications Posted on: July 06, 2018
Accurate characterization of Carbon (C) consequences of forest disturbances and management is critical for informed climate mitigation and adaptation strategies.

Northeastern California plateaus bioregion science synthesis

Projects Posted on: April 20, 2018
The Lassen and Modoc National Forests intend to update their Forest Plans, guided by the 2012 Planning Rule. This requires public and tribal input throughout the process and embraces the fact that ecological, social, and economic objectives are interrelated. Because ecological, social, and economic conditions have changed since the original forest plans were written and new science is available, preparing a science synthesis, guided by input from the public, tribes, and forest staffs, is the first step in a multi-step process that eventually leads to revised forest plans.
