Carbon sequestration is an important element in the discussion towards limiting the impacts of climate change. There are proposals to pay tropical countries to maintain their forests to maximize carbon sequestration. Vital to this proposal is the existence of a National Forest Inventory with statistically valid estimates of forest attributes.

The impacts of typical weed treatments on both the target weed(s) and non-target plant species that occur in large scale, chronic weed infestations are seldom quantitatively assessed or compared. Further, advantages or disadvantages of making high density ‘inundative’ biocontrol releases to counteract high levels of overwintering mortality affecting agent establishment and increase are seldom documented. Impacts of inundative biocontrol on...
There is new methodology for fitting ecologically feasible “shapes” to time series of Landsat imagery for modeling, mapping, and monitoring annual forest disturbance dynamics. Through a case study of fire, harvest and bark beetle outbreak, scientists illustrate how resultant fitted values and parameters can be fed into empirical models to map disturbance causal agent and tree canopy cover changes coincident with disturbance events through time.

Increases in forest fires are expected with future changes in climate, allowing more opportunities for post-fire salvage logging. Forest managers are challenged with implementing post-fire management policies while concurrently meeting the requirements of existing laws and planning documents to maintain habitat for wildlife species associated with snags. Design criteria for post-fire salvage logging is needed to concurrently manage for economic...

Researchers studied avian relationships with wildfire to evaluate forest fire and fuels management strategies. Specifically, they document regional differences associated with historical fire regime with implications for broadly implemented strategies aimed at reducing severe wildfire risk. The results suggest that avian-fire relationships differ regionally, and therefore the best management practices for conserving or restoring avian diversity...
Northern goshawk nestlings
The elusive northern goshawk, its forest habitats, and the habitats of its bird and mammal prey are significant conservation issues related to the management of forests throughout the hawk’s North American range.  The Rocky Mountain Research Station has been enumerating the population size and documenting the population ecology and demography of individual goshawks on Arizona’s Kaibab Plateau for 20 years with the objective of identifying the...

A new optimization technique will help conservation biologists choose the most cost-effective ways of connecting isolated populations of rare species. As the human population grows and expands its footprint, maintaining the connectivity of wildlife habitats is a challenge, but an RMRS-led team has developed tools for cost-effective solutions.
Young trees act as ladder fuel when they grow under large trees on Back Hills Experimental Forest Service.
Scientists across four experimental forests (Preist River, Black Hills, Boise Basin, and Deception Creek) worked to provide a suite of ecosystem services from removing fuels to implementing new strategies. Treatment goals were to increase the diversity of forest conditions across the landscapes and provide for a variety of ecosystem service, such as wildlife habitat, wild berries, wood for construction, and hunting opportunities.

Rocky Mountain Research Station scientists and their partners with the U.S. Forest Service Missoula Technology and Development Center, Washington State University, and John Jump Trucking, Inc., developed and tested a high-capacity biochar spreader to reduce the cost and facilitate the application of biochar as a soil amendment.
Researchers collect the forest floor for carbon determination.
Research at the Coram Experimental Forest points to resilient western larch forests in the cool-moist climatic regime that can fully recover carbon and nutrients before the next harvest rotation. Scientists used a site that had been harvested by cable logging and broadcast burning in 1974 to evaluate long-term impacts and recovery. Shrub diversity and biomass were the same or greater than pre-harvest samples and indicate the shrub community is...
