It is a plant of the sand dunes at separate beach locations in these counties. A very limited amount of this plant's habitat remains; it is a federally listed endangered species. Construction of golf courses on the Monterey Peninsula caused the extirpation of two known occurrences, and boardwalks were built at Asilomar State Beach to prevent trampling of the delicate dune habitat there.
Lupinus aridorum is a rare species of lupine known by the common name scrub lupine. It is endemic to Florida in the United States, where there were 10 known populations remaining in 2003. Fewer than 6000 individual plants were counted. It is threatened by the loss and degradation of its habitat. The scrub lupine is a federally listed endangered species of the United States.
