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,...

The goals of this study are to: (1) generate a genetic toolset (80-90 microsatellite loci per species) for long term genetic monitoring of both wild and captive populations of each threatened gartersnake species (THEQ & THRU) that inhabit Arizona and New Mexico; (2) conduct field surveys at Saliz Creek to assess the genetic, demographic, and life history effects of a 2012 wild translocation event for THRU to better assess the strategies of genetic management and success of translocations; (3) conduct targeted surveys for both species at key sites to collect additional samples from geographic gaps and increase sample sizes at previously sampled sites to further evaluate connectivity and genetic diversity of these...
Sky Island Alliance (SIA) is a non-governmental organizational that works to protect and restore the rich natural heritage of native species and habitats in the Sky Island Region. We work with volunteers, scientists, land-owners, public officials, and government agencies to establish protected areas, restore healthy landscapes, and promote public appreciation of the region’s unique biological diversity. Because of our long-standing collaborative relationships with land managers and our large corps of skilled volunteers, we were in a unique position to spearhead this project.SIA initiated this springs inventory, assessment and management planning project to develop baseline information on springs in the Sky Island...

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,...

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...

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....
