The red diamond rattlesnake, aka red rattlesnake or red diamond snake, can be found in southwestern California and Baja California. These pit vipers face the threats of habitat loss and destruction at the hands of farming, ranching, residential, and commercial developments; hunting; and trapping. Even through these adversities they are still abundant enough to be listed as Least Concern by the IUCN. Their population trend is listed as decreasing though.
