National flow gage gap analysis

Projects Posted on: March 16, 2017
Flow gages* record discharge in streams and rivers across the U.S. but the extent and adequacy of this monitoring network relative to USFS lands has not been documented. To address that deficiency, the medium resolution National Hydrography Layer was used with gage location information from the National Water Information System to describe the monitoring network and how it has changed through time.

Mapping climate refugia to preserve cold-water biodiversity using crowd-sourced databases

Science Spotlights Posted on: September 20, 2016
Concerns about climate change effects on cold-water biodiversity sparked broad multi-agency collaborative efforts throughout the American West. U.S. Forest Service research teams led development of massive interagency databases that now enable precise mapping of critical habitats and species distributions in streams flowing through 101 National Forests.

Forecasting the influence of climate change on invasive weeds and weed biological control

Science Spotlights Posted on: February 10, 2016
Rocky Mountain Research Station scientists are investigating how climate change, namely elevated levels of CO2, might impact invasive species and classical biological control of weeds. A mechanistic approach to understanding how climate change may impact interactions between invasive plants and their biocontrol agents is essential for realistically addressing management needs under likely future field conditions.

National forest contributions to streamflow: Intermountain Region (Region 4)

Pages Posted on: February 05, 2016
Maps and text files for each national forest in the Intermountain Region (Region 4) to illustrate the importance of national forest water yield to regional water quality and water quantity.

Ozone air pollution threatens remote mountain landscapes

Science Spotlights Posted on: October 05, 2015
Ozone (O3) is the most widespread air pollutant and is highly toxic to vegetation. Station researchers are using a portable battery powered monitor to evaluate O3 at several high-elevation, remote locations in the Rocky Mountain West. Research findings will allow national forests to determine O3 levels in remote areas where Air Quality Related Values are unknown, determine if O3 at these sites exceed the federal standard, and examine long-term changes in O3 in remote regions.

15,000 years of increasing aridity and herbaceous taxa loss

Science Spotlights Posted on: May 11, 2015
Modern vegetation analysis techniques were used to statistically analyze 154 plant taxa from 52 fossil woodrat midden strata from a cold desert area adjacent to Pyramid Lake. These midden strata were located over an 800 meter elevation gradient and covered the last 35,000 years. Analysis results show significant trends from 35,000 years ago to the present of a decreasing number of forb taxa, and an increasing number of shrub taxa.

Rocky Mountain Research Station scientists are investigating how climate change, namely elevated levels of CO2, might impact invasive species and classical biological control of weeds.

Multi-century fire-regime forensics: the past as a guide for restoring landscape resilience

Projects Posted on: April 16, 2015
Multi-century fire and forest histories are reconstructed using dendrochronological techniques to assess past variation in fire regimes at various scales of time and space.

Assessing the impacts of recent climate change on global fire danger

Projects Posted on: March 31, 2015
Wildfires occur at the intersection of dry weather, available fuel, and ignition sources. Weather is the most variable and largest driver of regional burned area. Temperature, relative humidity, precipitation, and wind speed independently influence wildland fire spread rates and intensities.

NorWeST: a regional stream temperature database and modeled climate scenarios

Documents and Media Posted on: January 23, 2015
Climate change is warming aquatic ecosystems and will have profound consequences. Effective conservation of aquatic resources will require unprecedented levels of interagency coordination.  In addition, it will require the development of datasets and models for accurate downscaling of climate change effects to important habitat parameters and species distributions at local scales.Document Type: Briefing Papers
