As some areas within the preserve have been degraded in the past, MRT has had many restoration projects there. MRT’s on-going restoration projects includes riparian and wetland enhancement by removing invasive non-native plant species to encourage the re-establishment and spread of native plant species. The primary invasive non-native plant species include yellow star thistle (Centaurea solstitialis), curly dock (Rumex crispus), plantains (Plantago lanceolata and P. major), spearmint (Mentha spicata) and a host of other annual and perennial invasive species. One restoration project includes improving habitat for the Lyon’s pentachaeta (Pentachaeta lyonii ), a Federally endangered species. In addition to removing non-native plants and planting natives at La Sierra PReserve, MRT is also working to remove a culvert, an asphalt driveway and retaining wall, and to restore a vernal pool.
La Sierra Preserve Restoration
La Sierra is a prime wildlife habitat, biologically diverse, and rich in willow riparian habitat, oak woodland, mixed riparian woodland, coastal sage scrub, wetlands, grassland, and chaparral. La Sierra provides habitat linkages to springs, seeps, and wetland areas that are critical to wildlife in the Malibu Creek watershed.
