Why are chenopod scrublands also called saltbush scrublands?

Chenopod scrublands are referred to as saltbush scrublands because they are named for their dominant vegetation, which belongs to the chenopod family, commonly known as the saltbush family.1

These plants, which include the genus Atriplex, are well-adapted to harsh, dry, and often saline environments. Because these shrubs are the primary species defining the structure and ecology of these specific scrubland regions, the terms are used interchangeably to describe the same habitat.123
