Soil and vegetation responses to 1967-1968 disturbances on the Miller Creek Demonstration Forest: thirty year data

Datasets Posted on: December 30, 2020
This data publication includes vegetation and soil data acquired 30-years after an experiment was initiated (1967-1968) on the Miller Creek Demonstration Forest in western Montana, USA, to determine the effects of harvest in combination with different prescribed fire severities on conifer regeneration. A wildfire in August 1967 burned or reburned initial plots.

Fire, larch, soil, and carbon: a 30-year-old story

Science Spotlights Posted on: December 18, 2020
Concern about changing climate is focusing attention on how silvicultural treatments can be used to regenerate or restore forested landscapes. In this study we leveraged a 30-year-old forest management-driven experiment to explore the recovery of woody species composition, regeneration of the charismatic forest tree species western larch, and vegetation and soil carbon and nitrogen pools. 

Vegetative and edaphic responses in a northern mixed conifer forest three decades after harvest and fire: Implications for regeneration and carbon and nitrogen pools

Publications Posted on: December 11, 2020
Research Highlights: This experiment compares a range of combinations of harvest, prescribed fire, and wildfire. Leveraging a 30-year-old forest management-driven experiment, we explored the recovery of woody species composition, regeneration of the charismatic forest tree species Larix occidentalis Nutt., and vegetation and soil carbon (C) and nitrogen (N) pools.

Upcoming: Tree regeneration following wildfires in ponderosa pine forests

Events Posted on: December 07, 2020
In this webinar, Paula Fornwalt will discuss a recent project that examined post-fire tree regeneration in ponderosa pine forests of Arizona, Colorado, Wyoming, and South Dakota.

Canopy structure and below-canopy temperatures interact to shape seedling response to disturbance in a Rocky Mountain subalpine forest

Publications Posted on: October 02, 2020
We examined the effects of two recent, high-severity disturbances on seed dispersal and conifer seedling establishment in a subalpine spruce-fir forest in the San Juan Mountains, Colorado. Our study area had undergone high forest mortality from a spruce beetle (Dendroctonus rufipennis) outbreak beginning ca. 2004, and a portion of the study area was additionally burned by the West Fork Complex wildfire in 2013.

"It’s all up from here": Forest openings and seedling growth in western white pine restoration

Publications Posted on: September 14, 2020
For centuries, western white pine (Pinus monticola) dominated moist forests of the northern Rocky Mountains. The fast-growing species, which can reach heights of 150 feet, was once an economic driver in the region. However, not much of the former forest remains. A combination of blister rust, beetles, and logging severely reduced the range of white pine during the 20th century.

Lick Creek: Lessons learned after 20+ years of fuel treatments in a ponderosa pine forest

Science Spotlights Posted on: September 08, 2020
Lick Creek is the longest running fuel treatment and restoration study of ponderosa pine forests in the northern U.S. Rocky Mountains. Through repeat photography and numerous published studies, we show how fuels and vegetation have changed over the 25 years since treatment and compare the effects of mechanical harvesting with and without prescribed burning.

Warmer temperatures directly and indirectly affect western larch regeneration

Science Spotlights Posted on: August 25, 2020
Forest inventory data reveal direct and indirect effects of climate on western larch regeneration. A direct effect of climate is the shift of western larch regeneration toward cooler, drier sites and less regeneration at warmer, wetter sites. An indirect effect is that warmer temperatures are linked to increased wildfire, and western larch seedlings were more prevalent at recently disturbed sites.

“It’s all up from here”: Forest openings and seedling growth in western white pine restoration

Documents and Media Posted on: July 27, 2020
Over a decade of research by Rocky Mountain Research Station scientists Terrie Jain and Russell Graham is now providing updated guidelines for regenerating and establishing white pine on the landscape by focusing on factors such as forest openings and visible sky. Document Type: Other Documents

Fuel treatment longevity in ponderosa pine-dominated forest 24 years after cutting and prescribed burning

Publications Posted on: July 11, 2020
Fuels reduction treatments to mitigate fire behavior are common in ponderosa pine ecosystems of the western United States. While initial impacts of fuel treatments have been reported, less is known about treatment longevity as live and dead fuels change with time.
