The purpose of the National Park Service’s Mediterranean Coast Network Invasive Plant Monitoring Program is to determine the status and trends in the distribution and cover of a targeted list of nonnative plant species in the Santa Monica Mountains National Recreation Area (SAMO), and to provide information to assist park managers with control of invasive plants. The monitoring is conducted at all point of entry survey sites (trailheads, parking lots, ports and campgrounds) and at randomly selected locations along dirt roads and trails on public lands throughout SAMO. This report summarizes the first five years (2016–2020) of monitoring points of entry and dirt roads and trails at SAMO with the approved protocol. The 2013–2014 annual report summarized the pilot data collected. The pilot methodology was modified to simplify data collection and to improve detection of invasive plants on dirt roads and trails. As with the pilot data, most invasive plants were found at points of entry, close to roads, trails, or other disturbances.
