i can send you a few billion oxalis and purselane seeds... those things seem to survive anything. and that crimon clover seems to be doing really really well too in those pictures. wait for it to go to seed and then harvest and spread it around before your next rainy season. eventually it will improve. may have to fence it off from the critters for a while to get it going and then keep an eye on it to rotationally graze it to not reset it back to sand again... p.s. include some alfalfa for deep rooting and nutrient mining. i've been impressed by how well it has worked here even with the rather shallow water table we have at times. after a few years the roots were an inch or more across and it was pretty tough to remove/dig up. could be mowed a few times a growing season if i had time for it and it always was a good refuge plant for various good bugs.
Won't plant alfalfa here, we have blister beetles here that emit a nasty toxin as they crawl across the alfalfa. It kills horses in a painful way. don't want any oxalis either, had it at our old house. I planted purslane here several times......no luck.
