Earlier this year, a grass species thought to be extinct was rediscovered. Prairie false oat (Sphenopholis interrupta ssp. californica) was previously only known from two locations in Baja California, Mexico from the 1880s. It was rediscovered near Carlsbad, California by Jessie Vinje (with the Conservation Biology Institute) and Margie Mulligan (with the San Diego Natural History Museum) while doing population monitoring for San Diego thorn-mint (Acanthomintha ilicifolia).
