The Colorado River is one of the most prominent and important river systems in North America. Today, water use by municipalities and irrigated agriculture, evaporation from reservoirs, and the invasion of non-native plants have resulted in the river running dry before reaching the sea. In the last two decades, numerous government and nongovernment agencies have taken actions specifically toward tamarisk and Russian olive. Given the size and diversity of the Colorado River Basin, the numerous and disparate management strategies, and the ecological concerns accompanying tamarisk and Russian olive, there remains the need to explore and develop methods to map native and non-native riparian vegetation and change over time.
