A Spring 2026 habitat restoration project along the banks of the San Lorenzo River in Santa Cruz by Central Coast Wetlands Group highlights the ongoing challenge of managing invasive plant species in urban riparian corridors such as this. Partnering with the Coastal Watershed Council, volunteers targeted a continuous half-acre plot heavily overgrown with non-native plants like mustard, hemlock, and a wall blackberry bushes standing up to five feet tall. Because the dense vegetation required significant person hours to clear, organizers brought in approximately 50 volunteers to tackle the site, ultimately filling a 15-yard dumpster with the removed blackberry over the course of many hours. However, despite their best efforts to pull up the roots, the blackberry and other non-native plants—such as summer mustard, red valerian, and Eurasian annual grasses—aggressively recolonized the plot within just four months (when we recorded this segment in June of 2026), underscoring the relentless and difficult nature of invasive species management.
