“…The most prevalent introduced riparian trees in the western United States are saltcedar (Tamarix chinensis, T. ramosissima and hybrids) (Gaskin and Schaal 2002) and Russian olive (Elaeagnus angustifolia L.) (Katz and Shafroth 2003). These species have become the second and fifth most abundant lowland riparian trees in the interior western United States (Friedman and others 2005a), occupying several hundred thousand hectares (Zavaleta 2000).…”

Removal of nonnative riparian trees is accelerating to conserve water and improve habitat for native species. Widespread control of dominant species, however, can lead to unintended erosion. Helicopter herbicide application in 2003 along a 12-km reach of the Rio Puerco, New Mexico, eliminated the target invasive species saltcedar (Tamarix spp.), which dominated the floodplain, as well as the native species sandbar willow (Salix exigua Nuttall), which occurred as a fringe along the channel. Herbicide application initiated a natural experiment testing the importance of riparian vegetation for bank stability along this data-rich river. A flood three years later eroded about 680,000 m 3 of sediment, increasing mean channel width of the sprayed reach by 84%. Erosion upstream and downstream from the sprayed reach during this flood was inconsequential. Sand eroded from channel banks was transported an average of 5 km downstream and deposited on the floodplain and channel bed. Although vegetation was killed across the floodplain in the sprayed reach, erosion was almost entirely confined to the channel banks. The absence of dense, flexible woody stems on the banks reduced drag on the flow, leading to high shear stress at the toe of the banks, fluvial erosion, bank undercutting, and mass failure. The potential for increased erosion must be included in consideration of phreatophyte control projects.

“…recruitment, which need bare soil to germinate (Katz et al 2001). Third, Russian olive is shade tolerant, allowing it to grow as an understory tree in cottonwood-willow gallery forests of the western Great Plains, where there are few native understory trees (Katz and Shafroth 2003). Because of its abundance in western U.S. riparian ecosystems and concern over its ecological impacts, a growing body of literature assesses the impacts of Russian olive on terrestrial wildlife and aquatic ecosystems (reviewed in Collette and Pither 2015;Katz and Shafroth 2003).…”

“…Russian olive is currently the fourth most frequently occurring and the fifth most dominant riparian tree species in the western United States . First introduced to the United States from western Asia and southern Europe in the early 1900s (Katz and Shafroth 2003), it is now found in all western U.S. states ) and southern Canadian provinces (Nagler et al 2011). Based on habitat suitability models, Russian olive is predicted to continue its expansion farther north and west in North America (Jarnevich and Reynolds 2011).…”

“…If depth to groundwater remains shallow and surface flow is perennial, high flows can slow the growth of sycamores, possibly through root hypoxia (Stromberg, 2001a). Late-season floods can also cause mortality through hypoxia, shear stress, and erosion (Stromberg, 1997;Tallent-Halstell and Walker, 2002;Katz and Shafroth, 2003).…”

“…Following decreasing reproduction and increasing mortality of native trees, drought-tolerant species such as saltcedar (Tamarisk spp.) and Russian olive (Elaeagnus angustifolia) may be released from competition, increasing their invasive capacity (Cleverly et al, 1997;Katz and Shafroth, 2003). A combination of increased frequency of heavy rains and decreased magnitude of spring floods, predicted by other climate change studies, may benefit late-successional species such as Arizona Walnut (Juglans major), mesquites (Prosopis spp.…”

a b s t r a c tRiparian ecosystems are vital components of aridlands within the southwestern United States. Historically, surface flows influenced population dynamics of native riparian trees. Many southwestern streams has been altered by regulation, however, and will be further affected by greenhouse warming. Our analysis of stream gage data revealed that decreases in volume of annual discharge and mean peak discharge and a shift to earlier peak discharge will occur in the Southern Rockies region of Colorado, New Mexico, and Utah. These changes will likely decrease rates of reproduction and survival of cottonwood (Populus fremontii and Populus deltoides ssp. wislizenii), Goodding's willow (Salix gooddingii), and boxelder (Acer negundo), which rely on surface flows to stimulate germination and recharge groundwater aquifers. Streams in the Central Highlands of Arizona and New Mexico will likely see reductions in annual discharge volume, which could limit reproduction and survival of the above taxa and Arizona sycamore (Platanus wrightii). These effects may be exacerbated by demands of expanding urban areas and agricultural operations, but could also be ameliorated by increasing water use efficiency and environmental mitigation. These factors must be considered, along with climate projections, when planning for conservation of riparian trees and the animal communities they support.
