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....

This is a habitat suitability model riparian understory species in the Colorado River bottomland in Utah. The model incorporates the density of shrubs, the number of shrub species present, and the stillness of adjacent water. A penalty value is applied to represent tamarisk abundance as a potential risk to habitat quality.

Tamarisk Probability Model for the Western United States. Thresholded at 0.6 for use in terrestrial intactness modeling. Extracted to the DRECP study area. New invasions, better field data, and novel spatial modeling techniques often drive the need to revisit previous maps and models of invasive species. Such is the case with the at least 10 species of Tamarix, which are invading riparian systems in the western United States and are expanding their range throughout North America. In 2006, we developed a National Tamarisk Map using a compilation of presence and absence locations with remotely sensed data and statistical modeling techniques. Since the publication of that work, our database of Tamarix distributions...
Tamarisk (Tamarix ramosissima Ledeb., T. chinensis Lour.), a pernicious invader of riparian areas in the western U.S., is often considered to be allelopathic by virtue of an ability to exude salt from its leaves. However, there is no evidence demonstrating allelopathy or even salinization of soils under tamarisk. We collected soil samples from beneath and just outside of tamarisk canopies at 12 sites along a 110-km reach of Fort Peck Reservoir in northeastern Montana. Samples were analyzed for electrical conductivity (EC), pH and concentration of several nutrients. Plants of western wheatgrass (Agropyron smithii Rydb.), the dominant herbaceous native plant in habitats invaded by tamarisk, were grown in the soil...

This dataset represents vegetation communities, river channel and bare areas (often sand bars) mapped along the Colorado River bottomland in Utah, as of September 2010. Dominant cover types were classified as 'open flight', based on height, and potential interference with bat flights over water sources. Traditional image interpretation cues were used to develop the polygons, such as shape, size, pattern, tone, texture, color, and shadow, from high resolution, true color, aerial imagery (0.3m resolution), acquired for the project. Additional, public available aerial photos (NAIP, 2011) were used to cross-reference cover classes. As with any digital layer, this layer is a representation of what is actually occurring...
