Grazing and logging effects on soil surface changes in central Colorado's ponderosa pine type

Publications Posted on: January 08, 2020
Measurements of soil surface elevation on ponderosa pine-bunch lands In central Colorado showed 35 years of grazing and winter logging had not caused serious erosion. All measurements indicated an aggradation of soil surface material In relation to differences in ground cover, grazing, and timber removal. Aggradation on ungrazed areas exceeded aggradatlon on grazed or logged areas by less than 7 millimeters.

Use of lidar-derived landscape parameters to characterize alternative harvest system options in the Inland Northwest

Publications Posted on: November 21, 2018
As innovative harvest systems are developed, the extent to which they can be utilized on the landscape based on machine capabilities is often unclear to forest managers. Spatial decision support models may aid contractors and forest planners in choosing appropriate logging systems based on topography and stand characteristics.

Abundance and characteristics of snags in western Montana forests

Publications Posted on: August 01, 2018
Plot data from the U.S. Forest Service's Forest Inventory and Analysis program was used to characterize the abundance and selected characteristics of snags from forests in western Montana. Plots were grouped by whether they had a history of timber harvest, and the U.S. Forest Service classifications of forest type, habitat type, and potential vegetation group were used to characterize plot conditions. Snag abundance was classified by d.b.h.

Effects and interactions of fire, logging, and grazing

Publications Posted on: August 01, 2018
In this chapter, we summarize current knowledge about the effects of fire, logging, and grazing on coniferous forest birds and their habitats. We critically review the results of studies evaluating how these individual factors influence bird numbers, species diversity, nesting success, and habitat use in ponderosa pine forests.

Wood use in Colorado at the turn of the twenty-first century

Publications Posted on: May 12, 2016
This study estimates the kinds, uses, amount, and retail value of wood products consumed annually in Colorado from 1997 to 2000. Colorado uses tremendous amounts of wood products, but it imports most of it from other states and countries despite the abundant forests in Colorado that are capable of providing many types of wood products.

Long-term landscape changes in a subalpine spruce-fir forest in central Utah, USA

Publications Posted on: March 23, 2016
In Western North America, increasing wildfire and outbreaks of native bark beetles have been mediated by warming climate conditions. Bioclimatic models forecast the loss of key high elevation species throughout the region. This study uses retrospective vegetation and fire history data to reconstruct the drivers of past disturbance and environmental change.

Clearcutting and burning slash alter quality of stream water in northern Idaho

Publications Posted on: August 17, 2015
In the cedar-hemlock-grand fir ecosystem clearcutting of units of varying size (2.6 to 44 ha) and subsequent disposal of slash by prescribed burning resulted in on-site stream water quality changes. But off-site changes were of less intensity. Two of three clearcut units responded in this manner; a third unit gave different results.

Chapter 12 - Bark Beetle outbreaks in Ponderosa Pine forests: Implications for fuels, fire, and management (Project INT-F-09-01)

Publications Posted on: November 24, 2014
Landscape-scale bark beetle outbreaks have occurred throughout the Western United States during recent years in response to dense forest conditions, climatic conditions, and wildfire (Fettig and others 2007, Bentz and others 2010).

Erosion processes and prediction with WEPP technology in forests in the Northwestern U.S.

Publications Posted on: June 28, 2013
In the northwestern U.S., the greatest amounts of forest erosion usually follow infrequent wildfires. Sediment from these fires is gradually routed through the stream system. The forest road network is usually the second greatest source of sediment, generating sediment annually. Erosion rates associated with timber harvest, biomass removal, and prescribed fire are generally minimal with current management practices.

Forest reference conditions for ecosystem management in the Sacramento Mountains, New Mexico

Publications Posted on: December 31, 2012
We present the history of land use and historic vegetation conditions on the Sacramento Ranger District of the Lincoln National Forest within the framework of an ecosystem needs assessment.
