Maintaining Sagebrush-Covered Landscapes Keeps Water on the Land for Ranchers and Wildlife

Thanks to  Justin Fritscher, Natural Resources Conservation Service, for bringing us this summary of research benefiting ranchers and wildlife. 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. Why is holding snow important for rangelands? In the West, most precipitation comes in the form of snow. Having snow on the landscape longer gives water more time to slowly seep into the ground, providing more water in the soil at critical times for plants, sustaining wet meadow areas, and increasing late-season streamflow. ARS researchers compared snow and streamflow data from sagebrush- versus juniper-dominated watersheds over the span of six years in the Owyhee Mountains of southwestern Idaho. Their goal was to better understand how juniper affects water availability. Wor
