The invasive aquatic plant Ludwigia has become an increasing problem within the Russian River watershed, and particularly in the Laguna de Santa Rosa. It outcompetes native plant species, hinders flood control, serves as prime habitat for mosquitos, and impedes the migration of anadromous fish, such as salmon and steelhead trout. The purpose of this project is to establish a method for using drone imagery to map the distribution of Ludwigia in a section of the Laguna de Santa Rosa near Stony Point Road in Rohnert Park, CA. We will compare mapping of Ludwigia distribution using drone imagery to traditional on-the-ground Ludwigia mapping.
