Cumulative drought and landâuse impacts on perennial vegetation across a North American dryland region
QUESTION: The decline and loss of perennial vegetation in dryland ecosystems due to global change pressures can alter ecosystem properties and initiate land degradation processes. We tracked changes of perennial vegetation using remote sensing to address the question of how prolonged drought and landâuse intensification have affected perennial vegetation cover across a desert region in the early 21st century? LOCATION: Mojave Desert, southeastern California, southern Nevada, southwestern Utah and northwestern Arizona, USA.
