Grasslands are among the most threatened ecosystems on the planet (Hoekstra et al 2004). Recently, the bird conservation and grasslands communities have united around a forward looking approach to conservation planning. To accomplish this the following information is needed:1) The location, quantity, and quality of desert grasslands,2) the regional risks associated with loss or degradation of grasslands,3) the vulnerability of those grasslands and the species that depend on them to environmental and climate stressors,4) where and what types of programs or partnerships exist on the landscape to address system stressors and implement further conservation programs, and5) what capacity for conservation do these entities...

Museum of Northern Arizona, Inc. will leverage tools previously developed by the Springs Stewardship Initiative to help resource managers in the southwestern U.S. collect, analyze, report upon, monitor and archive the complex and interrelated information associated with springs and spring-dependent species in the region. The information will be compiled and made readily available online. The Museum will further develop interactive online maps and climate change risk assessment tools of springs-dependent sensitive plant and animal species.

Riparian ecosystems are among the most productive and diverse ecosystems in desert biomes. In the Sonoran, Chihuahuan, and Mojave deserts of the United States and Mexico, riparian ecosystems support regional biodiversity and provide many ecosystem services to human communities. Due to the dynamic nature of these ecosystems and their abundance of resources, riparian areas have been modified in various ways and to a large extent through human endeavor to manage water and accommodate various land uses, particularly in lowland floodplains and stream channels. Modifications often interfere with multiple and complex ecological processes, resulting in the loss of native riparian vegetation and increasing vulnerability...

Amphibians and reptiles (herpetofauna) have been linked to specific microhabitat characteristics, microclimates, and water resources in riparian forests. 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,...

The project will result in recommendations for a decision support platform that links coarse and fine scale tools and for improving the Colorado River Simulation System (CRSS) as the central analytical tool for basinwide water supply planning. The work will largely be accomplished by assembling an exceptionally qualified team in cross-disciplinary, water management decision support systems, in the CRSS, and in two finer scale water management decision supports within the basin and by responding to an advisory group oflead water management agencies.The project will immediately build on the Colorado River Basin Water Supply and Demand Study being led by the U.S. Bureau of Reclamation, will extend the interface between...

Executive summary: Tamarisk control and removal has become a priority of riparian ecosystem management, due in part to its potential negative impacts on stream flow and groundwater recharge. 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. Superimposed on this direct plant/herbivore relationship...

University of California Riverside’s Center for Conservation Biology will create a sustainable resource monitoring framework that will provide empirical data identifying if and how climate change is changing the composition and vitality of Joshua Tree National Park. These data will then help focus the Park’s resource management programs to help ensure the Park’s rich biodiversity can be sustained to the extent possible. A broader goal is to have this framework adopted across the surrounding public lands to then integrate data from multiple sites and land management philosophies to create an unambiguous picture of the impacts of climate change across the desert region.

Description: Invasive saltcedar is the third most abundant tree in Southwestern riparian systems. 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....
