The stability of mean wood specific gravity across stand age in US forests despite species turnover

Publications Posted on: September 14, 2019
Research Highlights: Estimates using measurements from a sample of approximately 132,000 field plots imply that while the species composition of US forests varies substantially across different age groups, the specific gravity of wood in those forests does not.

Long-term precommercial thinning effects on Larix occidentalis (western larch) tree and stand characteristics

Publications Posted on: June 23, 2017
Precommercial thinning (PCT) is used to increase tree size and shorten harvest rotation time. Short-term results from PCT studies often show a trade-off between individual-tree growth and net stand yield, while longer-term effects of PCT on tree growth and stand yield are less well documented.

Endemic forest disturbances and stand structure of ponderosa pine (Pinus ponderosa) in the Upper Pine Creek Research Natural Area, South Dakota, USA

Publications Posted on: January 10, 2017
Disturbances are natural and essential components of healthy ecosystems, but their ecological roles in the maintenance of endemic conditions for an area (that is, long-established levels of activity that are of low magnitude and relatively static intensity and cause unnoticed or relatively low amounts of tree killing, defoliation, or deformation) are poorly understood.

Data supporting publication of fortifying the forest: thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience

Datasets Posted on: June 08, 2016
This package contains data used for the publication "Fortifying the forest: thinning and burning increase resistance to a bark beetle outbreak and promote forest resilience" (Hood et al. 2016). This study includes measurements from 1996-2012 at the Lubrecht Fire-Fire Surrogate Study Site, which was established in 2000 and includes four treatments, an untreated control, prescribed burn, a thinning, and a thinning followed by prescribed burn.

The Fire and Fuels Extension to the Forest Vegetation Simulator

Publications Posted on: May 12, 2016
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behaviour over time, in the context of stand development and management. Existing models of fire behavior and fire effects were added to FVS to form this extension. New submodels representing snag and fuel dynamics were created to complete the linkages. This report contains four chapters.

Dynamics of a pinyon-juniper stand in northern Arizona: a half-century history

Publications Posted on: May 12, 2016
This paper adds to the limited knowledge of stand dynamics in pinyon-juniper woodlands by reporting on the changes in species composition, numbers of trees, arrangements of trees, and total height and volume in a stand from late 1938 to early 1991. This information should be helpful in managing pinyon-juniper woodlands to sustain their productivity and maintain their multiple-use values.

Stand development and population dynamics of curlleaf mountain mahogany (Cercocarpus ledifolius Nutt.) woodlands in Utah's Bear River Mountains

Publications Posted on: November 10, 2011
Curlleaf mountain mahogany (Cercocarpus ledifolius Nutt.) is a little-studied woodland tree that occurs in pure stands throughout the Intermountain West. Stand development and population dynamics of this species are poorly understood, despite their relevance to management.

Addressing climate change in the Forest Vegetation Simulator to assess impacts on landscape forest dynamics

Publications Posted on: February 09, 2011
To simulate stand-level impacts of climate change, predictors in the widely used Forest Vegetation Simulator (FVS) were adjusted to account for expected climate effects.

Addressing climate change in the forest vegetation simulator to assess impacts on landscape forest dynamics

Publications Posted on: August 19, 2010
To simulate stand-level impacts of climate change, predictors in the widely used Forest Vegetation Simulator (FVS) were adjusted to account for expected climate effects.

Chapter 4: Variant descriptions

Publications Posted on: June 17, 2009
The Fire and Fuels Extension (FFE) to the Forest Vegetation Simulator (FVS) simulates fuel dynamics and potential fire behavior over time, in the context of stand development and management. This report documents differences between geographic variants of the FFE.
