Differing ponderosa pine forest structures, their growth and yield, and mountain pine beetle impacts: Growing stock levels in the Black Hills

Publications Posted on: July 16, 2019
Clifford A. Myers conceived the ponderosa pine growing stock levels (GSL) study in 1961 and completed installation of the study in 1963 in western South Dakota on the Black Hills Experimental Forest (BHEF). The GSL concept was intended to help plan, implement, and illustrate tree thinning strategies (from below) in even-aged stands. A GSL is the suggested tree density (i.e., trees and basal area per acre) based on d.b.h.

Connecting soils with forest productivity

Documents and Media Posted on: November 20, 2018
The productivity of Rocky Mountain forests is lower than forests in most other regions due to shorter growing seasons and low precipitation. Nutrient availability also appears to limit most forests in the region. Although operational fertilization remains uncommon in the region, standard forest management practices have large impacts on soils that can increase or decrease nutrient availability.Document Type: Other Documents

The impact of climate change on America's forests

Publications Posted on: August 01, 2018
This report documents trends and impacts of climate change on America's forests as required by the Renewable Resources Planning Act of 1974. Recent research on the impact of climate and elevated atmospheric carbon dioxide on plant productivity is synthesized. Modeling analyses explore the potential impact of climate changes on forests, wood products, and carbon in the United States.

Effects of climate change on forest vegetation in the northern Rockies [Chapter 5]

Publications Posted on: October 04, 2017
Increasing air temperature, through its influence on soil moisture, is expected to cause gradual changes in the abundance and distribution of tree, shrub, and grass species throughout the Northern Rockies, with drought tolerant species becoming more competitive. The earliest changes will be at ecotones between lifeforms (e.g., upper and lower treelines).

Development and use of a commercial-scale biochar spreader

Publications Posted on: August 16, 2016
Applying biochar to forest sites can be problematic and costly because of the need to keep the forest floor as undisturbed as possible during and after harvest operations. The Missoula Technology and Development Center of the U.S.

Testing the utility of the 3-PG model for growth of Eucalyptus grandis x urophylla with natural and manipulated supplies of water and nutrients

Publications Posted on: May 12, 2016
The productivity of fast-growing tropical plantations depends, in part, on the ability of trees to obtain and utilize site resources, and the allocation of fixed carbon (C) to wood production. Simulation models can represent these processes and interactions, but the value of these models depends on their ability to improve predictions of stand growth relative to simpler empirical approaches.

Fertilization in western larch forests

Documents and Media Posted on: August 20, 2015
Forest fertilization is effective as one means of increasing timber production. This report describes the status of fertilization research in the western larch type in Montana, and lists the locations of established experimental forest fertilization plots. Document Type: White Papers

Effects of climate change on adaptive variation, species distribution, and population connectivity of conifer species across the western United States

Science Spotlights Posted on: August 13, 2015
Climate change is dramatically altering the distribution, population connectivity and adaptive variation of conifer trees across the western United States, including large range shifts, reorganization of tree communities, die-offs, and decreases in productivity. This project has provided several important tools and applications to managers, including spatially explicit, fine-scale, broad-extent, quantitative predictions of changes in species distribution, adaptive variation and population connectivity for several conifer species across the full extent of the western United States.

Western North Carolina report card on forest sustainability

Publications Posted on: October 17, 2011
Western North Carolina encompasses 4.8 million acres of highly valued temperate forests. To help address future management and conservation decisions surrounding these resources, the report card evaluates environmental, social, and economic conditions in recent decades across an 18 county area. The report card describes the status of indicators of forest sustainability as improving, worsening, uncertain, stable, stable/at risk, or dynamic.
