Departments Join Forces to Weed Out Invaders

A multi-year project to remove invasive weeds at Lusardi Creek Preserve and Tijuana River Valley Regional Park

Agriculture, Weights and Measures (AWM) has begun working with Parks and Recreation (DPR) on a multi-year project to remove invasive weeds at Lusardi Creek Preserve and Tijuana River Valley Regional Park and replace them with native vegetation. DPR will enlist the California Conservation Corps to remove various invasive weeds prior to AWM treating re-growth with herbicides. The Lusardi Creek project is funded through a Transnet grant and will include the removal of pampas grass, arrundo, tamarisk, other non-native grasses and thistles. Treatments will take place over a three year period and cover about eight acres. The Tijuana River Valley Regional Park Project is funded through a Coastal Assistance Program grant and will concentrate on the removal of arrundo, tamarisk, chrysanthemum and ice plant. This is a two year project and will cover up to 33 acres. Restoration of these parks will bring back natural habitat and increase populations of native plants and animals.
