Effects of Bio-Control and Restoration on Wildlife in Southwestern Riparian Habitats

Our proposal addresses Funding Category Ill by evaluating natural resource management practices and adaptation opportunities. More specifically, our project addresses Science Need #6 to improve monitoring and inventory of watersheds and ecosystems (including invasive species). Our proposed study will occur within the Southern Rockies Landscape Conservation Cooperative (LCC) (upper Virgin River, UT) and the Desert LCC (lower Virgin River, AZ and NVL and therefore will be submitting to both cooperatives. Invasive saltcedar (Tamarix spp.) is the third most abundant tree in Southwestern riparian systems (Friedman et al. 2005). Resource managers must often balance the management goals of protecting wildlife species and...

Final Report: Effects of Biocontrol and Restoration on Wildlife in Southwestern Riparian Habitats

Introduction: Tamarisk (Tamarix spp., also saltcedar) is a non-native tree introduced to the United States during the 19th century as an ornamental species and solution to erosion in the American West (Robinson 1965). Tamarisk can form dense monotypic stands, which have been linked to a decline in richness and diversity of native plants (Engel-Wilson & Ohmart 1978; Lovich et al. 1994) and wildlife (Anderson et al. 1977; Durst et al. 2008) in riparian areas. As a result, natural resource managers have invested millions of dollars to control tamarisk (Shafroth & Briggs 2008). Few studies have conducted community-level analyses to document the impact of one of these methods, the introduction of a native enemy or predator,...

Temporal stability in hybridization between Bufo microscaphus and Bufo woodhousii (Anura: Bufonidae): behavior and morphology

I analyzed temporal variation in hybridization between the southwestern toad (Bufo microscaphus) and Woodhouse's toad (Bufo woodhousii) along the Virgin River in southwestern Utah and northwestern Arizona. Bufo woodhousii is largely restricted to the floodplain of the Virgin River from southern Nevada to the vicinity of St. George, Utah. By contrast, B. microscaphus is confined primarily to the tributaries of the Virgin River, only occupying the Virgin River proper exclusive of B. woodhousii along its upper reaches east of La Verkin Creek. As in all other zones of sympatry for these bufonids, behavior and morphology provide clear evidence of hybridization at a number of sites along the Virgin River. Analysis of...

Effects of Bio-control and Restoration on Wildlife in Southwestern Riparian Habitats (Not listed in the LCC Science Catalog due to Desert LCC co-funding and catalog administering)

Resource managers must often balance the management goals of protecting wildlife species and habitats with control of non-native and invasive plants. This project will determine if the introduction of the biocontrol agent (tamarisk leaf beetle, Diorhabda spp.) as an insect consumer and defoliator of saltcedar influences wildlife populations and communities via alterations to food resources and/or habitat. By taking advantage of an unprecedented natural experiment and two years of pre-biocontrol monitoring, the researchers will track changes in amphibian and reptile (herpetofauna), and avian communities as biocontrol enters a system dominated by a non-native plant species. The investigators predict that the introduction...

Publication: The effects of riparian restoration following saltcedar (Tamarix spp.) biocontrol on habitat and herpetofauna along a desert stream

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,...

Conservation Assessment for Native Fish in the Lower Colorado River Basin

This database contains physical and biological data for the Lower Colorado River Basin. The metrics include information on geology, hydrology, landcover, stewardship, topography, soil types and characteristics, stream characteristics, connectivity, and watershed position (information on where a stream segment or catchment is located in relationship to other segments or catchments; e.g. distance from a catchment to the mouth of the Colorado River, Shreve Link). In addition, there is a table with predicted probability of species occurrence for the connected stream segments and tables with the data used in those models. The species distribution models were completed for 18 native fish species and 21 non-native fish...

Science Brief for Resource Managers: Effects of Biocontrol and Restoration on Wildlife in Southwestern Riparian Habitats

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....

TDS concentration and load time series for Lower Colorado River Basin tributaries of the Colorado River from WRTDS modeling, 1938 to 2021

Total dissolved solids (TDS) in surface waters affect water quality and useability and are of particular concern in the Colorado River Basin. Estimates of current and past TDS concentration and flux in rivers support appropriate management and salinity control measures. In this study we estimated the total dissolved solid concentration and flux at 11 sites on tributaries of the Colorado River, starting as early as 1938 until 2021. Of these sites, eight were not affected by dams. For these we estimated daily and water year flow normalized TDS concentration and flux using the Weighted Regressions on Time Discharge and Season (WRTDS) water quality modeling framework. For the three sites situated below dams, we used...
