From the USDA Agricultural Research Service:
Scientists at the U.S. Department of Agriculture (USDA) have been investigating ways of using aerial photography and computer programs to quickly identify and measure areas affected by invasive trees. As a result, Agricultural Research Service (ARS) rangeland scientists Kirk Davies and Matt Madsen have developed tools that could help land managers protect sagebrush ecosystems and control invasive vegetation more economically and efficiently.
ARS is USDA's chief intramural scientific research agency, and this work supports the USDA priority of responding to climate change.
The expansion of western juniper trees on some arid U.S. rangelands is pushing out other plant species, reducing sagebrush habitat and livestock forage, and at times fueling catastrophic wildfires. Davies and Madsen, who work at the Eastern Oregon Agricultural Research Center in Burns, Ore., led studies on using National Agricultural Imagery Program (NAIP) high-resolution aerial images to estimate western juniper cover.
