Abstract
Invasive tamarisk shrubs pose a considerable threat to ecosystems of the American West, where they out-compete native riparian vegetation, by thriving in drought, being resilient to fire, increasing soil salinity, and reproducing quickly and profusely. This research examines the utility of freely available 30 meter resolution Landsat 8 imagery in monitoring and mapping the spread of tamarisk, by comparing supervised classifications of tamarisk percent cover in Landsat 8 imagery against high resolution aerial imagery, referencing field gathered tamarisk spectral signatures. Field data were acquired in Owens Valley, CA, where management efforts against tamarisk spread are ongoing.
