What is SageSTEP?

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.

Using germination prediction to inform seeding potential: II. comparison of germination predictions for cheatgrass and potential revegetation species in the Great Basin by Nathan Cline, Bruce Roundy, Stuart Hardegree and William Christensen.


Using germination prediction to inform seeding potential: I. Temperature range validation of germination prediction models for the Great Basin, USA by Nathan Cline, Bruce Roundy, and William Christensen.

Germination models predict germination timing under seedbed water potential and temperature conditions. Using a wet thermal time model for germination prediction, we estimated progress toward germination (PTG) of 31 seedlots (10 species) as a function of hourly seedbed temperature (> 0 °C) when soils were above a water potential of −1.5 MPa. Seasonally-summed progress toward germination with a value > 1 indicates that germination will occur for that season. We used near surface (1–3 cm) soil water potential and temperature measurements collected at 24 sites in the Great Basin to determine effects of site, season, and year on PTG. On tree encroached sites, we also determined effects of tree infilling phase at time of tree removal, removal method,and microsite on estimated PTG.

Unmined Treasures: An Invitation to Dig into SageSTEP Data and Sites

When establishing the scope of the SageSTEP project, we realized that what we were doing could be useful for more than just our own research questions. Despite now having published more than120 technical papers on all aspects of the study, we are still awash in unpublished stories. This is where you come in. We are issuing an open invitation to use SageSTEP data and sites to discover some of those important stories for yourself.

Farewell to a Friend: SageSTEP Pioneer Paul Doescher

We wanted to acknowledge the recent passing of our valued SageSTEP colleague and friend Paul Doescher. Paul made many contributions to Range Ecology, and to SageSTEP in particular...

New Research

Response of bird community structure to habitat management in piñon-juniper woodland-sagebrush ecotones in Forest Ecology and Management.

Management actions using prescribed fire and mechanical cutting to reduce woodland cover and control expansion provided opportunities to understand how environmental structure and changes due to these treatments influence bird communities in piñon-juniper systems. Steve Knick and other authors surveyed 43 species of birds and measured vegetation for 1–3 years prior to treatment and 6–7 years post-treatment at 13 locations across Oregon, California, Idaho, Nevada, and Utah and used structural equation modeling to develop and statistically test a conceptual model that the current bird assembly at a site is structured primarily by the previous bird community with additional drivers from current and surrounding habitat conditions as well as external regional bird dynamics.

Ecological Consequences of Pinyon and Juniper Removal; Six Years Later

The longer-term consequences of tree removal is becoming easier to evaluate, thanks to recently published research by Rachel Williams, Bruce Roundy and others. This research details the fate of the understory after treatments designed to address ongoing pinyon-juniper expansion at six years after treatment. Trajectories diverge over time.

Developing Technology to Reduce Seeding Failure

Arid land seedings often fail, as newly germinated seedlings are lost to harsh environmental conditions. To counter this, Matthew Madsen and Bruce Roundy at Brigham Young University are developing new technologies to improve seeding success on these complex and sometimes inhospitable landscapes.

Pasta VideoWhen scientists were looking for a better way to restore sagebrush they thought way outside of the box. The solution — a pasta maker. Check out this short video to see how it is done.


Video and Infographic on Carbon and Climate Change

Restoration of Great Basin sagebrush steppe is about more than rebuilding healthy landscapes ... these environments also influence global climate change through large-scale carbon systems. Check out a three-minute video that introduces the relationship between carbon sequestration, climate change, fire and the health of Great Basin lands. See a user-friendly infographic on the same subject. Feel free to share and print these products.

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.
