Indigenous to Peru, Chile, and Argentina, the woody plant called Prosopis juliflora (also known by the American common name of “Honey Mesquite”) has spread world-wide in recent decades, including rangelands throughout Latin America, North America, south and central Asia, Australia, and sub-Saharan Africa. A species known for rapid establishment, high adaptability, and fast rates of growth, its dispersal has primarily been a consequence of intentional introduction by well- meaning “technical experts” who wanted to provide a new source of fodder, fuel wood, or a means to combat desertification in arid and semi-arid lands. One problem, however, is that unless Prosopis receives careful management, it can invade and degrade ecosystems. Here we report on interviews conducted among rural residents of central Kenya where Prosopis was first introduced over 20 years ago. The respondents contend that Prosopis has greatly undermined their livelihoods, and they want to see it eradicated.
