SMCP Devil’s Slide Trail Invasive Plant Management

cliffside management of invasive Jubata Grass along the Devil's Slide Trail to enhance restored native habitat

WRA is working with the San Mateo County Parks Department to remove the ecologically-destructive invasive species Jubata Grass (Cortaderia jubata) that has overtaken the steep cliffs surrounding the Devil’s Slide Trail in Pacifica, California. Using ropes and harnesses, WRA Landscape Restoration staff rappel down the rocky cliffs to spot-target individual plants using an approved herbicide to kill above- and below-ground plant matter and allow for native species to recolonize the bare rock along the wind-swept coastline. After three years of seasonal spraying and subsequent monitoring and maintenance by WRA specialists, the environment is expected to be restored to its natural healthy state, allowing for sensitive native species to grow unencumbered in the area once more. Native plant species have evolved to tolerate the unique conditions of the area, and they provide important habitat as well as erosion control. In addition to restoring a beautiful recreation area, the project will protect the many seabirds, insects, reptiles, and mammals that call this coastline home.
