On two separate transects in the Rock Valley area of the northern Mojave Desert in the spring of1976, 4 percent to 17 percent of the perennial plants were infested with the parasite Cuscuta nevadensis Jtn. (dodder), and dead pieces of dodder from previous years were on dead plants equivalent to another 5 percent, indicating that the dodder had a regulating effect on the plant population and may be an important cause of perennial plant death.
