Identifying old trees to inform ecological restoration in montane forests of the central Rocky Mountains, USA

Publications Posted on: April 05, 2019
Old trees (defined here as ≥150 years old) can be rare in many forests because of past timber harvest, uncharacteristically severe wildfires, and - increasingly - climate change. Old trees provide unique structural, ecological, scientific, and aesthetic values missing in forests containing only younger trees.

Wildfires and climate change push low-elevation forests across a critical climate threshold for tree regeneration

Publications Posted on: March 21, 2019
Climate change is increasing fire activity in the western United States, which has the potential to accelerate climate-induced shifts in vegetation communities. Wildfire can catalyze vegetation change by killing adult trees that could otherwise persist in climate conditions no longer suitable for seedling establishment and survival.

Managing habitats for white-tailed deer in the Black Hills and Bear Lodge Mountains of South Dakota and Wyoming

Publications Posted on: February 26, 2019
The white-tailed deer is one of the most studied animals in North America, yet much of the available information has been derived in ecosystems different from the Black Hills. The Black Hills are unique in that the dominant species, ponderosa pine, has excellent regenerative abilities.

Ponderosa pine seedling response to planting-site soil fumigation and fungicide application

Documents and Media Posted on: December 07, 2018
Ponderosa pine (Pinus ponderosa Laws.) was used as a biological model to determine the effects of planting site soil fumigation and fungicide applications on stock planted in moderately-fertile soils of the Intermountain West of the United States. Five soil fumigation (Vapam) treatments, singularly and in combination with fungicide (triadimefon) applications, were compared to a control.Document Type: Other Documents

Restoration treatments in a Montana ponderosa pine forest: Effects on soil physical, chemical and biological properties

Documents and Media Posted on: November 30, 2018
Low-elevation ponderosa pine ecosystems of the inland northwestern United States experienced frequent, low-severity fire that promoted open stands dominated by large diameter ponderosa pine (Pinus ponderosa). Fire exclusion has led to increased stand densities, often due to proliferation of less fire-tolerant species and an increased risk of stand-replacing wildfire.Document Type: Other Documents

Looking Into the Past: How Reconstructing Historical Forest Conditions Can Help Future Restoration Efforts

Documents and Media Posted on: November 14, 2018
This Science You Can Use in 5 Minutes looks at ponderosa-dominating forests and how looking at historical structures helps restore these forests. Document Type: Other Documents

Condition of live fire-scarred ponderosa pine twenty-one years after removing partial cross-sections

Publications Posted on: October 05, 2018
Concern over the effects of removing fire-scarred partial cross-sections may limit sampling of live ponderosa pine to reconstruct fire history. We report mortality rates for ponderosa pine trees 20 to 21 years after removing fire-scarred partial cross-sections to reconstruct fire history.

Assessing high-cost wildfires in relation to the natural distribution of ponderosa pine in the 11 Western states (2000-2017)

Publications Posted on: October 04, 2018
In this analysis we introduce a broad-scale long-term overview of the US West’s costliest wildfires in relation to the natural distribution of ponderosa pine (Pinus ponderosa). The species is dependent on frequent, low-intensity burning, but in absence of this function, it has become one of the region’s most altered ecosystems (U.S. Government Accounting Office, 1999; U.S.D.A.

Site productivity and soil conditions on terraced ponderosa pine sites in western Montana

Documents and Media Posted on: October 03, 2018
The USDA Forest Service built terraces on the Bitterroot National Forest in the1960s and1970s as a means of mechanical site preparation prior to machine-planting ponderosa pine (Pinus ponderosa) in clearcuts. We examined the in fluence of terracing on planted ponderosa pine and soil characteristics more than 20 yr after site treatment and planting.Document Type: Other Documents

Mexican spotted owl home range and habitat use in pine-oak forest: Implications for forest management

Publications Posted on: August 01, 2018
To better understand the habitat relationships of the Mexican spotted owl (Strix occidentalis lucida), and how such relationships might influence forest management, we studied home-range and habitat use of radio-marked owls in ponderosa pine (Pinus ponderosa) Gambel oak (Quercus gambelii) forest.
