32 33 In contrast, the streams of western North America contain many fewer species. Because the major drainages are isolated from each other by mountain ranges, the number of endemic species (those confined to single drainages) is high and often adjacent drainages will share few species. For example, the SacramentoSan Joaquin drainage (California) on the west side of the Sierra Nevada shares only one native species (speckled dace) with the drainages of the Great Basin on the east side. A high percentage of the species are large as adults and are long-lived.
