ABSTRACT
Due to the environmental and economic consequences of long term, substantial groundwater use, Arizona and its stakeholders have had to adopt and implement new policies to address groundwater pumping. Survival of riparian ecosystems depends upon the existence of consistently high groundwater levels that are within reach of vegetation in riparian corridors. The effects of pumping caused by a quickly growing population’s increasing demand for water threaten both existing riparian ecosystems and the long term water security of that same population.
