Flight of the Mountain Pine Beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), in Suburban Cheyenne, Wyoming, USA during Summer 2011

Publications Posted on: February 08, 2021
The mountain pine beetle (MPB), Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae: Scolytinae), is a major tree-killing bark beetle that attacks primarily ponderosa pine, Pinus ponderosa Lawson & C. Lawson, and lodgepole pine, Pinus contorta Douglas ex Loudon (Pinaceae), among other pines, across the western coniferous forests of North America (Negron and Fettig 2014).

Northern Arizona, USA, post-wildfire avian data: western bluebird detection/non-detection and banding data

Datasets Posted on: December 30, 2020
Western bluebird (Sialia mexicana) population data were collected in northern Arizona, USA, following two wildfires (Hochderferr Fire, Horseshoe Fire) that occurred in May and June 1996. This is a data subset consisting of 8 years of bird data collection post-wildfire (1999-2006) and 3 years of vegetation data (2002, 2005, 2006), and is part of a larger long-term data set.

Post-fire field observations across the 2007 Egley Fire in central Oregon (1st Edition)

Datasets Posted on: December 30, 2020
This data publication contains field observations taken in 2008 at 350 plots within the extent of the 2007 Egley Fire in central Oregon. Plots were located as paired sites in areas that had been treated and untreated prior to the 2007 Egley Fire. Field observations include a suite of vegetation, soil, fuel, and surface cover characteristics.

Lick Creek Demonstration-Research Forest: Data and photo archive of 25-year fire and cutting effects on vegetation and fuels

Datasets Posted on: December 30, 2020
This data publication contains vegetation, fuels, and repeat photopoint data for the Lick Creek Demonstration-Research Forest Commercial Thinning + prescribed fire and Retention Shelterwood + prescribed fire study areas in western Montana. Pretreatment data were collected in 1991. The Commercial Thinning and Retention Shelterwood project areas are each stand-alone studies located in different areas and data should not be combined.

Tree-ring growth and stable-carbon isotope response data to forest restoration treatments in ponderosa pine forests of the Lick Creek Demonstration-Research Forest, Bitterroot National Forest, Montana, USA

Datasets Posted on: December 30, 2020
This data publication includes the data used in "Forest restoration treatments in a ponderosa pine forest enhance physiological activity and growth under climatic stress" by Tepley et al. (2020).

Historical tree surveys of the Umatilla National Forest

Datasets Posted on: December 30, 2020
The original public land survey for the Umatilla National Forest was completed primarily between 1879 and 1887. Notes from these General Land Office (GLO) surveys provide the earliest systematically recorded information about species composition for national forest system lands in the Blue Mountains of northeastern Oregon and southeastern Washington.

Forest restoration treatments in a ponderosa pine forest enhance physiological activity and growth under climatic stress [Bulletin]

Publications Posted on: December 11, 2020
Stand-density reduction treatments are widely applied to restore historic stand structure and increase resistance to high-severity fire in dry ponderosa pine forests. Little is known about whether the removal of competition also alters tree responses to drought, and if so, how long those effects persist, or the underlying mechanisms.

Fire-catalyzed vegetation shifts in ponderosa pine and Douglas-fir forests of the western United States

Publications Posted on: November 18, 2020
Increased wildfire activity combined with warm and dry post-fire conditions may undermine the mechanisms maintaining forest resilience to wildfires, potentially causing ecosystem transitions, or fire-catalyzed vegetation shifts. Stand-replacing fire is especially likely to catalyze vegetation shifts expected from climate change, by killing mature trees that are less sensitive to climate than juveniles.

Discovering Douglas-fir woodlands in the historical forests of the Umatilla National Forest, eastern Oregon and Washington

Publications Posted on: October 28, 2020
We discovered unique Douglas-fir open woodlands in the Umatilla National Forest using historical surveys. Historical ponderosa pine forests of the western United States are transitioning to denser forests comprised of a greater proportion of fire-sensitive species, including true firs.
