Wyatt Rovera (left) and Anders Reimer, restoration technicians at the Mountain Trust Restoration, wake up every morning and don waterproof waders. Between 8 a.m. and 2 p.m. they slog through over two miles of creek in the Malibu Creek Watershed, checking 300 traps for red swamp crayfish. The Mountain Trust's goal is to completely eradicate the invasive species from the entire watershed, an unprecedented scope.
