Life as a desert shrub


For nearly three decades we have been annually censusing the population dynamics of three common Mohave and Sororan Desert shrubs: Encelia farinosa, Encelia frutescens, and Hymenoclea salsola. The three populations are monitored in the Death Valley, Calfornia area; a second E. farinosa population is monitored in the Oatman, Arizona area. This long-term monitoring of birth, growth, reproduction, and death of individual plants is one of the longest, continuous monitoring efforts in North American desert ecosystems.
