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,...

Larval headwater stream amphibian captures from the Trask River Watershed Experimental Study of forest harvest impacts, 2008-2016

Forest harvest is one of the primary landscape-scale management actions affecting riparian forests of the Pacific Northwest, U.S, yet the effect of harvest on headwater steam amphibians is largely understudied. Existing information is often limited because of the difficulty separating movement and emigration processes from occupancy and abundance estimates. We designed a before-after control-impact experiment to account for instream movement in the responses of three unique headwater stream amphibians to clearcut logging as part of the Trask River Watershed Experimental Study in the Oregon Coast Range. We captured and marked larval tailed frogs (Ascaphus truei), Coastal giant salamanders (Dicamptodon tenebrosus),...

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...

Provision and inventory of diverse aquatic ecosystem-related resources for the GPLCC

The basic task of inventorying biodiversity has actually been under way for many years. Existing natural history museum collections, like those in which we work, can provide major contributions to such inventories in the form of valuable historic organism occurrence records, and their specimens can be used in many ways for basic research and applied conservation planning. Unfortunately, much of the wealth of information stored in natural history collections requires substantial investment to be made accessible and useful to natural resource managers and researchers. We were charged by the GPLCC with providing some of the inventory data that will be required, and to assess what other data may be available and what...

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,...
