Saltbushes are extremely tolerant of salt content in the ground: their name derives from the fact that they retain salt in their leaves, which makes them of great use in areas affected by soil salination. Atriplex species are used as food plants by the larvae of some Lepidoptera species; see the list of Lepidoptera which feed on Atriplex. For spiders such as Phidippus californicus and other arthropods, sal
