Abstract

Over the years, humans have modified the Sonoran Desert by introducing invasive plants that prosper in disturbed and non-disturbed habitats. These invaders modify the dynamics and structure of populations and the composition of communities, which in turn can result in radical changes in wildlife habitat. The natural landscape of the Sonoran Desert is characterized by extensive valleys with parallel and discontinuous arrangements of narrow ranges (Shreve and Wiggins, 1964). Within this ecosystem is the heart of the Sonoran Desert called the Pinacate Reserve (Reserva de la Biosfera El Pinacate y Gran Desierto de Altar). The Pinacate Reserve registers 97 invasive plant species, of which 18 are altering the natural ecosystems.
