Where the Sage-grouse Roam

04.08.2004


Symposium 5: Fighting the Odds: The Challenge to Save the Sagebrush Biome will be held in Oregon Ballroom 203 on Tuesday, August 3, 8:00 AM to 11:30 AM at the Oregon Convention Center



The sagebrush biome covers forty million hectares of the American West. Shaped by climate, fire, floods and volcanic eruptions since the Pleistocene era, the sagebrush biome now faces the impacts of increased cultivation, urbanization, exotic plant species, and altered fire patterns. In a session to be presented at the ESA 89th Annual Meeting entitled “Fighting the Odds: The Challenge to Save the Sagebrush Biome,” researchers will discuss the history of the area and current projects underway to understand and restore this ecosystem. Rick Miller (Oregon State University) will introduce the session.

Michael Schroeder (Washington Department of Wildlife) will examine the impact of ecosystem changes on the distribution of the greater sage-grouse and the Gunnison sage-grouse in his presentation, “Changes in the distribution of sage-grouse in North America.” Allen Rasmussen (Texas A&M University) will follow with a discussion on the suppression of fire in settled areas and the increases of fire fueled by cheatgrass in his presentation “Invasive species and fire cycles in sagebrush steppe ecosystems.”


Exploring the effects of sheep and cattle, Kris Havstad (USDA Agriculture Research Service) and Marty Vavra (Starkey Experimental Forest) will present their talk, “Impacts of livestock grazing in sagebrush ecosystems. Focusing on the basic foraging behavior of livestock, they will review and characterize the direct and indirect impacts of managed grazing on sagebrush steppe rangelands.

The lands also play a role in oil and gas production. A majority of leases for gas and oil development are on federal lands in regions such as the Wyoming Basin and eastern Great Basin. Discussing a recent analysis under the Energy Policy and Conservation Act, Sean Finn, along with coauthors Steven Knick (USGS) and Thomas Rinkes (Bureau of Land Management), will discuss impacts of oil and gas development on sagebrush ecosystems in their talk “Impact of energy development on sagebrush ecosystems.”

Ronald Nielson (USFS) will discuss the possibility of the sagebrush biome being squeezed by desert-like plants from the south and trees moving downslope from mountains in the talk, “Climate change implications for sagebrush ecosystems.” Nielson will discuss the research he and colleagues James Lenihan (USFS) and Dominique Bachelet (Oregon State University) completed on frost patterns and the possible impacts of climate change on the Great Basin Ecosystems.

Steven Knick will describe how he and his USGS colleagues, Matthias Leu and Thomas Loveland, combined satellite imagery of habitats and surveys of sage sparrows, Brewers sparrows, and other bird species living within 250-meter buffers along roadsides in their paper, “Effect of multiscale habitat change in populations of birds breeding in sagebrush habitats.”

After exploring the changes to the sagebrush biome the session will shift to restoration and land management. David Pyke (USGS) will describe the results of a four-state study of Bureau of Land Management wildfire rehabilitation projects in his presentation, “Restoration and rehabilitation – Bridges to build and impediments to success.” Pyke’s talk will be followed by a study on the close association between sage-grouse population success and sagebrush habitats completed by John Connelly (Idaho Department of Fish and Game), Kerry Reese (University of Idaho,) and Michael Schroeder (Washington Department of Wildlife). In “Restoration and recovery of sagebrush landscapes: a sage-grouse viewpoint,” Connelly will discuss sage-grouse preferences in relation to landscape restoration.

“Economic and social ramifications of alternate management priorities in sagebrush ecosystems” will be presented by John Tanaka (Oregon State University, Union). The project is a collaborative effort between Tanaka, L. Torrel (New Mexico State University), Neil Rimbey (University of Idaho, Caldwell), Larry Van Tassell (University of Idaho, Caldwell), Tim Darden (New Mexico Department of State), and Aaron Harp, a consultant in Ann Arbor, Michigan. Using examples from Oregon, Nevada, and Idaho, Tanaka will explain how various restoration options could affect cattle ranches and rural communities.

John Freemuth’s (Boise State University and Cecil Andrus Center for Public Policy) talk, “The policy landscape of the sagebrush ecosystem,” will take a closer look at the politics behind management and recovery issues surrounding the sagebrush ecosystem.

Closing the session, Joel Brown, Brandon Bestelmeyer, and Jeffrey Herrick (Jornada Experimental Range) will argue that institutional guidelines for management are inadequate without a more localized set of scenarios. Brown will describe the group’s suggestion for solving this problem in his presentation, “A manager’s dilemma: Making logical decisions at the local scale.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
