Piddling around Aracata, California, I wandered into the Humboldt Coastal Nature Center. It's about a ten minute walk to the beach through native plants that have been laboriously put in place after removing, individually, the invasives.
Charles & Rachel Stamps, children of the '60s, used an Earth Shelter kit for the house and 3,100 tires, laid over the top, to hold the sand, their chosen form of earth, to keep it from slipping off or being blown away. Part of the renovations, begun in 2007, involved disposing of the tires. (The info doesn't say what they used instead.)
