“…Economic Importance and Environmental Impact (a) Detrimental Á Economic and environmental impacts are a result of saltcedar's ability to invade and dominate an area, out-competing native plants for resources (Hart et al 2005). The invasion by saltcedar is reported to be one of the worst ecological disasters impacting riparian ecosystems in the United States, replacing native plants, degrading wildlife habitat and biological diversity, increasing fire frequency, as well as being associated with the decline of threatened and endangered species (DiTomaso 1998;DeLoach et al 2000;Kauffman 2005).…”

“…The most detrimental environmental impact of saltcedars is on hydrological regimes which include reducing water flow and lowering water tables (DeLoach et al 2000;Hart 2005). Changes in water flow can also result in increases in salinity that further encourage the establishment of saltcedar (DiTomaso 1998 Salt-secreting glands on the leaves excrete numerous salts and minerals, increasing soil salinity (Berry 1970) and killing salt-intolerant plants (DeLoach et al 2000).…”

“…Kauffman (2005) reported that various herbicides (i.e., imazapyr, metsulfuron methyl, ammonium salt of fosamine, triclopyr, and glyphosate) have been used against saltcedar since the 1940s, but that control is never complete and reinfestation may be rapid. In a restoration project in Texas, Hart et al (2005) reported an average of 85Á90% mortality of saltcedar 2 yr after applications of Arsenal TM herbicide applied by helicopter with a specially designed boom. Herbicide control can be effective in the short-term; however, periodic retreatments are required with repeated costs and environmental damage (DeLoach et al 2009).…”

“…However, this treatment would not be effective or practical for large populations. The integration of conventional control methods, such as fire followed by herbicides, or fire and/or herbicides followed by rootploughing and raking has provided increased control in some cases (Grubb et al 2002;Hart 2003). However, these methods greatly increase costs and still do not eliminate the need for repeated application to control regrowth or re-invasion unless dense stands of native plants can be re-established to exclude or suppress the saltcedar.…”

These Tamarix species and their hybrids, known collectively as saltcedar, are perennial small trees or shrubs native to Eurasia, and were among the Tamarix species introduced to the United States in 1800s as ornamentals, for plantings in windbreaks, and to stabilize eroding stream banks. They have since escaped and become damaging invasive plants in large areas of the western and Great Plains regions of the United States. They are able to reproduce vigorously by both seed and vegetative propagation, and are persistent and long-lived once established. Ecological problems include hydrologic impacts, displacement of native flora and fauna including endangered species, and excretion of salt, which increases soil salinity. Economic impacts include costs associated with control as well as losses of irrigation and municipal water, flood control costs, and loss of recreational opportunities. Invaded habitats include floodplains, salt flats, marshes, reservoirs, stock watering ponds, and irrigation ditches. Saltcedar is difficult to control and almost impossible to eradicate once established. In 2007, naturalized saltcedar was found near Penticton and at Osoyoos Lake in British Columbia, Canada. It is also currently sold in several Canadian provinces as an ornamental. Ecological niche modelling indicates that large areas of the Canadian Prairies are susceptible to invasion. Hybridization, multiple intentional introductions through garden plantings, natural dispersal from populations in the northern United States, and climate warming will increase the risk and promote the spread of saltcedar in Canada. Key words: Saltcedar, Tamarix ramosissima, Tamarix chinensis, invasive alien plant, weed biology, invasion biology, ecological niche modeling

“…On a larger scale, other management groups have targeted entire tributaries, such as major sections of the Pecos River in New Mexico and Texas, with broadcast chemical applications. Along the Pecos River, Texas from 1999 to 2004, 5169 ha of salt cedar along 434 km of the river and its tributaries have been treated, at a cost of US$2.5 million (US$407/ha), with 85-90% kill (Hart et at., 2000(Hart et at., , 2005Hart, 2004Hart, , 2006, and the present cost is now US$580/ha. Such areawide chemical application techniques often require several follow-up treatments to kill salt cedar regrowth and, when successful, are unfortunately equally devastating to most of the other vegetation in the area, as the chemicals used for salt cedar control have little or no selectivity.…”

Areawide Pest Management: Theory and Implementation

View full text Add to dashboard Cite

This chaper describes an areawide pest management (AWPM) approach for salt cedar (Tamarix spp.) in the Western USA. The low beneficial value of salt cedar, its lack of closely related plants in the Western hemisphere and the large number of host-specific and damaging natural enemies that attack it within its native distribution in the Old World, make salt cedar an almost ideal invasive weed for an AWPM programme using biological control as its keystone technology. The development and implementation of education and technology transfer programmes are discussed for the development of the AWPM programme for salt cedar. The implementation of the AWPM programme and its compatibility with crop management and management of co-occurring pests and native species; efficacy at controlling the target pest; unintended negative and positive consequences; and economic benefits are also discussed. Remote sensing results are presented from only a few of over a dozen specific research sites examined. Examples are provided to cover the many different methods that have been used, alongside detailed assessments of aerial photography from Cache Creek (California) of salt cedar density and hyperspectral imagery from Lovelock and Schurz (Nevada) to demonstrate beetle (Diorhabda elongata) establishment, spread and defoliation impact on salt cedar populations. Prospects for the long-term sustainability of the AWPM programme are given.

River channel response to invasive plant treatment across the American Southwest

Invasive riparian plants were introduced to the American Southwest in the early 19th century and contributed to regional trends of decreasing river channel width and migration rate in the 20th century. More recently, efforts to remove invasive riparian vegetation (IRV) have been widespread, especially since 1990. To what extent has IRV treatment reversed the earlier trend of channel narrowing and reduced dynamism? In this study, paired treated and untreated reaches at 15 sites along 13 rivers were compared before and after IRV treatment using repeat aerial imagery to assess long‐term (~10‐year) channel change due to treatment on a regional scale across the Southwest USA. We found that IRV treatment significantly increased channel width and floodplain destruction. Treated reaches had higher floodplain destruction than untreated reaches at 14 of 15 sites, and IRV treatment increased the rate of floodplain destruction by a median factor of 1.9. The effect of treatment increased with the stream power of the largest flow over the study period. Resolving observations of channel change into separate measures of floodplain destruction and formation provided more information on underlying processes than simple measurements of channel width and centerline migration rate. Restoration practitioners who perform IRV treatment projects often focus on wildlife or vegetation response; however, geomorphic processes should be considered in restoration planning because they drive aquatic habitat and vegetation dynamics, and because of the potential for damage to downstream infrastructure. Depending on the restoration goal, management practices can be used to enhance or minimize the increase in channel dynamism caused by IRV treatment.
