The purpose of this agreement is to initiate SRLCC-wide data discovery, cataloging, and general GIS analysis to characterize the landscape across the SRLCC geographic area. The SRLCC has identified the need for a data management activity to support all aspects of data discovery, dissemination, cataloging, and analysis. An existing agreement between FWS and the USGS provides for an SRLCC catalog inside the U.S. Geological Survey-sponsored ScienceBase scientific data and information management platform and provides the ability for partner organizations to maintain and contribute to this work environment. Initial information and data discovery process will compile existing resources in the ScienceBase SRLCC data portal...

Abstract: Climate change predictions include warming and drying trends, which are expected to be particularly pronounced in the southwestern United States. 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...

Academics & scientific researchers,
Assessing the vulnerability of species or ecosystems to climate change and formulating appropriate management responses requires predictions of the exposure and sensitivity of the species or ecosystems to projected changes. This collaborative effort by the Sonoran Joint Venture, Desert Landscape Conservation Cooperative, and Point Reyes Bird Observatory will develop a foundation for monitoring environmental change in the desert southwest by identifying where and what to monitor in order to evaluate climate-change impacts.Climate change will not have the same effects in all locations of the southwest. Some areas will change quickly (hotspots) and others will change slowly (refugia). Identifying both types of areas...

The Desert Landscape Conservation Cooperative (LCC) is a partnership formed and directed by resource management entities as well as interested public and private entities in the Mojave, Sonoran, and Chihuahuan Desert and montane sky island regions of the southwestern United States and northern Mexico. Desert LCC science depends on access to transboundary base datasets. Given the importance of vegetation such as grasslands and riparian vegetation in conservation science, a bi-national, landscape-scale vegetation data layer with classes relevant to Desert LCC research is crucial. One objective of this project is to investigate appropriate methodologies and landscape scales to create a Desert LCC binational land cover...
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...

In February 2014, taking action to implement a 2012 U.S.-Mexico agreement on the Colorado River known as Minute 319, International Boundary and Water Commissioners (IBWC) Edward Drusina and Roberto Fernando Salmon Castelo announced plans to move forward with a one-time pulse flow (a release of water into the Colorado River channel below the last dam on the River) as well as a five-year commitment by a coalition of Non-Governmental Organizations to deliver base flow water. Minute 319’s environmental water deliveries to the Colorado River Delta are intended to restore native riparian habitat along the river corridor, where invasive non-native saltcedar has displaced the native willow and cottonwood trees that provide...

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,...

This project will build upon a recently completed synthesis product for the Southwest and review and analyze vulnerability assessments of aquatic species and habitats within the Southern Rockies Landscape Conservation Cooperative. Southwestern riparian systems support a disproportionate amount of the regional biodiversity and are likely to be strongly affected by changes in climate with a concordant disproportionate effect on surrounding landscapes and features. The SRLCC encompasses the Upper Colorado River Basin and a portions of the Lower Colorado and Rio Grande Basins. These systems represent some of the most critical water sources in the west and are likely to experience some of the most extreme changes in...

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...

Land managers have incorporated threats to biodiversity for nearly two decades, but very few efforts have included threats from future conditions and fewer still have assessed vulnerability to climate change. This project will address two themes: 1) providing foundational information about habitat fragmentation and connectivity and 2) identifying the degree of vulnerability of key habitats to climate change.For development of understanding broadextent, a landscape-level pattern of climate change is an important complement to approaches to estimate rangeshifts for certain key focal species. Ecological system types (i.e. coarsefilters) are widely used in conservation planning because they contain valuable resources...

Riparian vegetation provides crucial habitat for wildlife and is a high conservation priority for land managers throughout the Southwest but a central scientific challenge is to generate quantitative predictions of how changes in water availability will affect the amount and quality of riparian wildlife habitat. Researchers will study areas that have long-term datasets available (i.e., hydrological, geomorphological, biological), that characterize a broad range of riparian conditions found in the Southwest. Building on recently developed models funded by the USGS National Climate Change and Wildlife Science Center (NCCWSC), this work will link various hydrologic, geomorphic and habitat models to better understand...

ABSTRACT: The Lower Colorado River and Rio Grande Basins are home to many riparian vertebrate species with different degrees of rarity. In our study, we focused on two species of birds and two species of gartersnakes that are associated with riparian areas: the Yellow-breasted Chat (Icteria virens), the Yellow Warbler (Setophaga petechia), the Northern Mexican Gartersnake (Thamnophis eques megalops) and the Narrow-headed Gartersnake (T. rufipunctatus). While the extent of distributions of these species is relatively large, they are often patchily distributed in populations that are small; in addition, both gartersnake species are listed as threatened under the Endangered Species Act. Aside from detrimental effects...

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....
