Environmental flows in the desert rivers of the United States and Mexico: Synthesis of available data and gap analysis Article Abstract: Although riparian and aquatic ecosystems make up a small fraction of the area in arid and semi-arid lands, they are critical for the survival of desert life. There are, however, few compendia of efforts to define the quantity of water needed to maintain these ecosystems and understand the risks and stressors to them. Through our analysis we found that 62% of the rivers examined in the deserts of the U.S. and Mexico have had just one study over the past four decades and 67% of studies used qualitative methods. Furthermore, only one-third of the 312 species catalogued in our work have been studied more than once and only 5% have been considered five or more times. The most common risks or stressors...

This guidebook provides information on a variety of methods that can be utilized under different fiscal or temporal constraints to determine and implement appropriate environmental flow targets. Based on evidence from cases focused in the Southwestern United States and Northern Mexico, steps are suggested to help ensure maintenance of flows under uncertain future natural and socioeconomic conditions. The importance of education and engagement to increase acceptance of environmental flows based projects and gain key player and community buy in is described. Limitations on...

In this region, grassland dynamics are tightly linked to available moisture, yet it has proven difficult to resolve what aspects of climate drive vegetation change. In part, this is because it is unclear how heterogeneity in soils affects plant responses to climate. Here, we combine climate and soil properties with a mechanistic soil water model to explain temporal fluctuations in perennial grass cover, quantify where and the degree to which incorporating soil water dynamics enhances our ability to understand temporal patterns, and explore the potential consequences...

To create a one-stop-shop for published ecological water needs information and illuminate critical knowledge gaps in the desert watersheds of the U.S. and Mexico, the University of Arizona’s Water Resources Research Center and the Northern Arizona University School of Earth Sciences and Environmental Sustainability created the Desert Flows Database....

Our objective was to relate variation in herpetofauna abundance to changes in habitat caused by a beetle used for Tamarix biocontrol (Diorhabda carinulata; Coleoptera: Chrysomelidae) and riparian restoration. During 2013 and 2014, we measured vegetation and monitored herpetofauna via trapping and visual encounter surveys (VES) at locations affected by biocontrol along the Virgin River in the Mojave Desert of the southwestern United States. Twenty-one sites were divided into four riparian stand types based on density and percent cover of dominant trees (Tamarix,...

Among the most controversial, and potentially most effective tamarisk control approaches is the introduction of the tamarisk leaf beetle, Diorhabda carinulata. The beetle has spread throughout virtually the entire upper Colorado River Basin, established major populations at Lake Mead in 2012, and is now poised to expand into the lower Colorado River Basin concordant with documented evolutionary change in beetle developmental response that may enable survival in southern regions.

Resource managers must often balance the goals of protecting native wildlife species and habitats with the control of non-native and invasive plants. This project examined the impact of the tamarisk leaf beetle (a biocontrol agent) on amphibian and reptile (herpetofauna) and bird populations and communities along the Virgin River in Utah, Arizona and Nevada.Building on two years of pre-biocontrol monitoring, the researchers tracked changes in herpetofauna communities as the biocontrol entered a system dominated by a non-native plant species. The tamarisk leaf beetle is known to be eaten by several wildlife species....
