Abstract

Tule Creek is an intermittent stream draining Sonoran desertscrub in Yavapai Co., Arizona. An 800-m segment has perennial surface discharge and was the site of a ciénaga community dominated by Scirpus olneyi and Anemopsis californica. Extensive flooding in winter 1978 had the following immediate impacts on the system: 1) an introduced population of the endangered Sonoran topminnow (Poeciliopsis o. occidentalis) was destroyed, 2) substrate erosion and entrainment removed vegetation, reduced number of pools, straightened and deepened the channel; and 3) canyon treefrog (Hyla arenicolor) and saltcedar (Tamarix chinensis) were introduced.
