Area burned in alpine treeline ecotones reflects region-wide trends

Publications Posted on: March 17, 2017
The direct effects of climate change on alpine treeline ecotones – the transition zones between subalpine forest and non-forested alpine vegetation – have been studied extensively, but climate-induced changes in disturbance regimes have received less attention.

Long-term landscape changes in a subalpine spruce-fir forest in central Utah, USA

Publications Posted on: March 23, 2016
In Western North America, increasing wildfire and outbreaks of native bark beetles have been mediated by warming climate conditions. Bioclimatic models forecast the loss of key high elevation species throughout the region. This study uses retrospective vegetation and fire history data to reconstruct the drivers of past disturbance and environmental change.

Projecting outcomes for high elevation pine populations threatened by a non-native disease

Projects Posted on: December 03, 2014
White pine blister rust (WPBR) is a lethal disease threatening five-needle pine species in the Northern Rocky Mountains. Through the use of mechanistic models, we are developing mitigation and prevention strategies.

Innovative control and management of white pine blister rust – the proactive strategy for mountaintop ecosystems

Projects Posted on: December 03, 2014
RMRS and partners have developed a strategy to sustain healthy high elevation pine populations and mitigate the impact of invasion by the non-native pathogen that causes the lethal disease white pine blister rust. This approach provides the science foundation for proactive management.   

Changing climates, changing forests: A western North American perspective

Publications Posted on: September 27, 2013
The Earth’s mean surface air temperature has warmed by ~1C over the last 100 years and is projected to increase at a faster rate in the future, accompanied by changes in precipitation patterns and increases in the occurrence of extreme weather events.
