Ecology, silviculture, and management of Black Hills ponderosa pine

Publications Posted on: June 22, 2020
This paper presents a broad-based synthesis of the general ecology of the ponderosa pine ecosystem in the Black Hills. This synthesis contains information and results of research on ponderosa pine from numerous sources within the Black Hills ecosystem.

Example SDI-based prescriptions: Treatment prescriptions for commercial harvest units, Trout West Fuels Reduction Project, Manitou Experimental Forest

Publications Posted on: December 23, 2019
The sites described below are located in Ponderosa pine Forest Type on the Manitou Experimental Forest. The sites are bounded by meadows along Trout Creek on the west, Hotel Gulch, on the south, Missouri Gulch on the north, and the Ridgewood subdivision on the east. The area consists of gentle west-sloping terrain intersected by a series of small east-west ridges. No live streams exist in the area. Elevations range from 7,700 to 8,000 ft.

GENGYM: A variable density stand table projection system calibrated for mixed conifer and ponderosa pine stands in the Southwest

Publications Posted on: February 26, 2019
A computerized growth and yield model based on a variable density stand table projection system using 1-inch-wide diameter classes has been developed for projecting expected stand conditions in southwestern mixed conifer and ponderosa pine stands, including the effects of dwarf mistletoe. Stand management options include both even-aged and uneven-aged cutting methods.

Uneven-aged management on Fort Valley Experimental Forest

Projects Posted on: October 17, 2017
This project continues research that began in 1925, measuring trees within a study block that has used even and uneven-aged management techniques, to determine the growth and how climate variables may have impacted this. Previously-measured trees were remeasured in 2017, and tree data will be correlated with long-term weather data at FVEF. Measurements will continue to be taken into 2018.

Managing burned landscapes: Evaluating future management strategies for resilient forests under a warming climate

Publications Posted on: July 08, 2015
Climate change effects on forested ecosystems worldwide include increases in drought-related mortality, changes to disturbance regimes and shifts in species distributions. Such climate-induced changes will alter the outcomes of current management strategies, complicating the selection of appropriate strategies to promote forest resilience.

Variable-retention harvesting as a silvicultural option for lodgepole pine

Publications Posted on: September 26, 2014
Bark beetle-induced mortality in forested landscapes of structurally uniform, even-aged lodgepole pine stands has inspired a growing interest in the potential of silvicultural treatments to enhance resilience by increasing spatial and vertical complexity.

Management guide to ecosystem restoration treatments: two-aged lodgepole pine forests of central Montana, USA

Publications Posted on: October 25, 2012
Lodgepole pine is one of the most widely distributed conifers in North America, with a mixed-severity rather than stand-replacement fire regime throughout much of its range. These lodgepole pine forests are patchy and often two-aged. Fire exclusion can reduce two-aged lodgepole pine heterogeneity.

Restoration of northern Rocky Mountain moist forests: Integrating fuel treatments from the site to the landscape

Publications Posted on: May 04, 2009
Restoration and fuel treatments in the moist forests of the northern Rocky Mountains are complex and far different from those applicable to the dry ponderosa pine forests. In the moist forests, clearcuts are the favored method to use for growing early-seral western white pine and western larch. Nevertheless, clearcuts and their associated roads often affect wildlife habitat, water and soil resources, and scenic values.
