EXPLORING HOW DESIS IMAGERY CAN ENHANCE THE CHARACTERIZATION OF LAND SURFACE PHENOLOGIES IN MONTANE PASTURES

We developed the maps to identify the spread of an invasive plant, yellow sweetclover, in the western South Dakota from 2016 to 2023 using satellite and drone imagery. Our study shows that the plant blooms widely during wet years and is often found near roads and moist areas. The developed percent cover maps using field data, drone images, and machine learning models would help land managers find and control this invasive species, protecting Northern Great Plains grasslands.
