“Resilience” is the ability to recover from change, or when you think about landscapes, the ability to recover from disturbances like wildfires. A new model takes the idea of resilience and applies it to the natural environment, specifically, to sagebrush. This resilience model is one of the core elements of the new Science Framework for Conservation and Restoration of the Sagebrush Biome (Part 2).

The charismatic sage grouse is often in the spotlight as the flagship species in the sagebrush ecosystem. The smaller songbirds that live alongside the grouse don't always attract as much attention, but they are also good indicators of how the sagebrush range is faring.

Recently, in a project funded by the Sage Grouse Initiative (SGI), the U.S. Fish and Wildlife Service (FWS) and Intermountain West Joint Venture (IMJV), scientists set out to evaluate whether investments in sage grouse conservation serve as an “umbrella” that extends benefits to other sagebrush-dependent wildlife, too. These findings are summarized in a new Science to Solutions report by SGI, a partnership led by USDA’s Natural Resources Conservation Service (NRCS).

This past April, we woke up at 3 a.m. and made our way to a blind amid an expanse of sagebrush on a ranch in central Montana. When the sun rose that morning, I saw my first sage grouse--actually, I got to see more than 100 of them!--when the birds arrived at the lek site for their famous tail-shaking springtime courtship dance.

Seeing sage grouse in action reminded me how important it is to do what we do here at USDA’s Natural Resources Conservation Service (NRCS). I saw firsthand how agriculture and wildlife can co-exist and thrive. In the West, we work with over 1,300 ranchers through the NRCS-led Sage Grouse Initiative (SGI) to improve their ranching operations while also helping this iconic bird.

Removing invading conifer trees improves the health of sagebrush ecosystems, providing better habitat for wildlife and better forage for livestock. And now, new science shows these efforts may also help improve late-season water availability, which is crucial for ecosystems in the arid West.

According to the Sage Grouse Initiative (SGI)’s newest Science to Solutions report – which summarized research from USDA’s Agricultural Research Service (ARS) – a sagebrush-dominated watershed holds water in snow drifts an average of nine days longer than one dominated by juniper trees.

Wildfires in sagebrush and other range ecosystems are increasing in frequency and severity, often in relation to drought conditions and intrusive species like cheatgrass, a non-native, highly flammable invasive species that establishes itself as a monoculture and crowds out native grasses and forbs.

“What’s preferable to a monoculture is a diverse plant community that includes native grasses, forbs and shrubs,” said Francis Kilkenny, leader for the Great Basin Native Plant Project, a joint effort of the U.S. Forest Service and the Department of Interior’s Bureau of Land Management, or BLM.

The need for food and shelter for wildlife to survive is basic, particularly for sage grouse living in a post-wildfire landscape in western states. The U.S. Forest Service is helping this upland game bird survive by growing about 3 million sagebrush shrubs a year to restore the area’s dry, grassy plains, essential for the bird’s nesting grounds.

“Our goal is to help accelerate the restoration process on our public lands,” says Clark Fleege, manager of the Lucky Peak Nursery, part of the Boise National Forest.
