What is SageSTEP? (Click here)

SageSTEP (Sagebrush Steppe Treatment Evaluation Project) is a regional experiment evaluating methods of sagebrush steppe restoration in the Great Basin. Sagebrush communities have been identified as one of the most threatened land types in North America, and as much as half of this land type has already been lost in the Great Basin. From 2005-2010, fuels treatments were implemented at study sites and SageSTEP scientists began looking at the short-term effects of land management options on a variety of ecosystem components. In 2011, we began a long-term monitoring phase of the project to better understand the changes in response to treatment over time. Research results are being used to provide resource managers with information to make restoration management decisions with reduced risk and uncertainty.

New Research

Wildland Fire JournalNew research by Kert Young, Bruce Roundy, Steve Bunting
and Dennis Eggett is now available from the International Journal of Wildland Fire. The authors treated pinyon-juniper trees to reduce canopy fuel loads and crown fire potential. They measured the effects of juniper–piñon infilling and fuel-reduction treatments on fuel loads at four locations in Utah. By 2 years after the treatment, herbaceous fuel loads were greater than pretreatment in all treated areas. Cut and mastication treatments increased surface woody 10- and 100-h fuel loads and wood/bark cover. The conversion of canopy fuels to surface fuels reduced fuels that enable crown fire and extreme fire intensity. To read more, click here.

Field Guide for Selecting Appropriate Treatments

Field GuideA revised Field Guide for Selecting the Most Appropriate Treatment in Sagebrush and Piñon-Juniper Ecosystems in the Great Basin is now available. This guide by Rick Miller, Jeanne Chambers, and Mike Pellant is designed to allow field personnel to evaluate resilience to disturbance and resistance to invasive annual grass for an area of concern, predict the potential successional pathways, and then select the most appropriate treatment, including the need for seeding.

 

 

Pinyon and Juniper Expansion Infographic

InfographicTake a look at our new infographic on the expansion of Pinyon and Juniper Trees in the Great Basin. It presents the problem in simple terms and lays out the strengths and weaknesses of three of the remedies that SageSTEP scientists are studying ... prescribed fire, tree cutting, and tree shredding. This is great for a quick reference on what we know (and don't yet know) about how landscapes will respond after these treatments, and about what may happen in the future if nothing is done.

New Research: Feral horses on Sagebrush Steppe

Feral HorseIn Ecosphere, find an article on the effects of feral free-roaming horses on semi-arid rangeland ecosystems by K. Davies, G. Collins and C.S. Boyd. Feral horses are relatively unmanaged, and information about their influence on semi-arid rangelands has been limited. Researchers compared plant and soil characteristics in horse-grazed areas to ungrazed exclosures in northern Nevada. The cumulative effects of feral horses suggest that they may increase the risk of soil erosion, and decrease availabile water for plant growth. Feral horses may limit sagebrush recruitment, having a negative impact on Greater Sage-grouse and other sagebrush associated wildlife.

Agencies have new tool for managing fire, invasives

Scientists are rolling out a new strategy this week to fight wildfire and cheatgrass threatening the greater sage grouse. The goal is to help the Bureau of Land Management and Forest Service place firefighting assets, target vegetation treatments and launch rehabilitation projects for burned landscapes in the Great Basin.

"This is the first time we've developed a landscape-scale prioritization for addressing wildfire and invasive threats," said Jeanne Chambers, a research ecologist at the Forest Service's Rocky Mountain Research Station, who was the lead author of a report detailing the strategy. "We're really excited about the work being applied."

The agencies are amending land-management plans across the West, but they have finite resources for preventing wildfires and performing treatments that benefit sage grouse. Chambers and her colleagues are set to present the report at a conference in Boise, Idaho, to facilitate discussion between scientists and land-management officials on how to address wildfire and invasive species in sage grouse habitat.

The Chambers report is among the first to bring together an interdisciplinary group of researchers and managers from the Forest Service, U.S. Geological Survey, USDA's Natural Resources Conservation Service and Agricultural Research Service, Bureau of Land Management, and state wildlife agencies.

Mechanical Mastication of Utah Juniper Encroaching Sagebrush Steppe Increases Inorganic Soil N
by Kert Young, Bruce Roundy and Dennis Eggett
in Applied and Environmental Soil Science.

Juniper mechanical mastication increases cover of understory species but could increase resource availability and subsequently invasive plant species. We compared resource availability in paired masticated and untreated areas in three juniper-dominated sagebrush and bunchgrass ecosystems in the Utah portion of the Great Basin. Read more.

ElementaWarming, soil moisture, and loss of snow increase Bromus tectorum's population growth rate
in Elementa, Science of the Anthropocene.

Cheatgrass (Bromus tectorum) is arguably the most destructive biological invader in basins of the North American Intermountain West, and warming could increase its performance through direct effects on demographic rates or through indirect effects mediated by loss of snow. Scientists conducted a two-year experimental manipulation of temperature and snow pack to test whether 1) warming increases cheatgrass population growth rate and 2) reduced snow cover contributes to cheatgrass’ positive response to warming.

Environmental ManagementAn Object-Based Image Analysis of Pinyon and Juniper Woodlands Treated to Reduce Fuels
in Environmental Management, December 2013
April Hulet, Bruce A. Roundy, Steven L. Petersen, Ryan R. Jensen and Stephen C. Bunting

Mechanical and prescribed fire treatments are commonly used to reduce fuel loads and maintain or restore sagebrush steppe rangelands across the Great Basin where pinyon and juniper trees are encroaching. Geospatial technologies, particularly remote sensing, could potentially be used in these ecosystems to evaluate the longevity of fuel reduction treatments, provide data for planning and designing future fuel-reduction treatments, and assess the spatial distribution of horizontal fuel structure following fuel reduction treatments.

 

Assessing the Relationship between Ground Measurements and Object-Based Image Analysis of Land Cover Classes in Pinyon and Juniper Woodlands
in American Society for Photogrammetry and Remote Sensing: October 2013.
April Hulet, Bruce A. Roundy, Steven L. Petersen, Ryan R. Jensen, and Stephen C. Bunting.

Land managers need to rapidly assess vegetation composition and bare ground to effectively evaluate and manage shrub steppe communities. We used an object-based image analysis (OBIA) approach to estimate land cover classes found in pinyon-juniper woodlands, and evaluated the relationship between ground measurements and OBIA land cover measurements. Although OBIA cover estimates varied slightly from ground cover estimates, methods provide land managers with options for prioritizing management practices and enabling monitoring at an operational scale.

 

Tree reduction and debris from mastication of Utah juniper alter the soil climate in sagebrush steppe
in Forest Ecology and Management: December 2013.
Kert R. Young, Bruce A. Roundy, and Dennis L. Eggett.

We determined the effects of tree reduction and soil cover in the forms of tree mounds and masticated debris on hourly soil water potential and soil temperature at 1–30 cm soil depth. Measurements were made in masticated and untreated areas at three sites in the western Utah portion of the Great Basin.

 

Plant Establishment in Masticated Utah Juniper Woodlands
in Rangeland Ecology & Management: September 2013.
Kert R. Young, Bruce A. Roundy, and Dennis L. Eggett.

Mechanical mastication where juniper density is high and perennial grass cover is low brings a risk of invasive weed dominance unless perennial species are established. To determine whether juniper mastication favors annual- or perennial-grass establishment, we compared seedling emergence, tillers, and aboveground biomass of cheatgrass and Anatone bluebunch wheatgrass.
