Book Description
Excerpt from The Battle Against Saltcedars (Tamarix Spp.) Saltcedars are occasional weeds with minor impacts in the Eastern United States. However, in the Western United States, saltcedars are highly invasive weeds that infest more than million acres ha), causing economic losses that exceed $250 million annual ly. Invasive saltcedars can cause serious environmental damage by consuming excessive amounts of water, displacing native plant communities, increasing wildfire frequency and flooding risks, reducing wildlife habitats and recre ational areas, and increasing the salin ity of soil. In turn, these environmental conditions indirectly cause economic hardship to the agricultural industry municipal and regional water suppliers, and local governments.

Excerpt from Results of Field Applications of Herbicides for Control of Saltcedar (Tamarix Spp.) For aerial applications of foliage spray herbicides, plot size was x 72 feet, or 2 acres. Both helicopter and fixed-wing aircraft were used. Unless otherwise specified, all aerial applications of herbicides were applied at a volume of 10 gallons per acre.

Book Description
Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Book Description
Saltcedar (Tamarix spp.) covers nearly 86,000 acres in Oklahoma mostly in the western third of the state. A beetle, Diorhabda carinulata (Coleoptera: Chrysomellidae) has been released in nine western states as a biological control agent. The U.S. Fish and Wildlife Service asked that we attempt to introduce the beetle into the Great Salt Plains Wildlife Refuge in Oklahoma, which is infested with saltcedar. We surveyed three saltcedar stands (Lake site, Highway site, Marsh site) from 2009-2010 at the refuge that were selected for their unique ecological characteristics. Our objectives were to compare two sampling methods (vacuum and beat stick) for their capability to assess the diversity of insect predators in different saltcedar-dominated habitats and identify potential arboreal predators of D. carinulata. The results of the survey indicated that several arthropod predators were abundant enough to potentially effect the establishment of D. carinulata. Comparison of insect assemblages between sampling methods revealed that the vacuum sampling technique recovered more overall taxa but neither method recovered all taxa present highlighting the importance of employing multiple sampling methods. The most common insect predators collected were Coccinella septempunctata (Coleoptera: Coccinellidae) in 2010 vacuum samples and Zelus tetracanthus (Hemiptera: Reduviidae) in 2009 vacuum and 2010 beat stick samples. Diversity indices (Shannon Diversity Index and Simpson Diversity Index) indicated that the Lake Site habitat was consistently more species rich than the Highway and Marsh Site. Two coccinellids, C. septempunctata and Hippodamia convergens, were identified as common predators present. We selected these two species for additional lab studies designed to evaluate the suitability of eggs and larvae of D. carinulata as a food source for the adults and larvae of both coccinellids. The studies revealed that D. carinulata is neither a suitable nor an acceptable food source for larval stages of both beetles. Adult lady beetles of both species attacked eggs and first instar D. carinulata larvae, but only one attack was recorded on a D. carinulata life stage beyond first instar. These results indicate that adult C. septempunctata and H. convergens could prove to be a limited predator of D. carinulata eggs and first instar larvae.

Book Description
The invasive species Saltcedar is affecting water and land resources throughout the western states of America. Because of great water use capabilities and other ecosystem detriments, Saltcedar has been targeted for treatment. For successful management of Saltcedar, individual landowners need to be aware of the costs and benefits of treating Saltcedar. Eleven of the most commonly reported treatment methods were evaluated for firm level economic feasibility. Evaluated on the basis of treatment cost, treatment effectiveness, Saltcedar water-use, and re-vegetation water-use, a production plan of ten years was created for each treatment method. Some treatment methods required re-treatment and were evaluated with re-treatments most commonly found in the literature. Of the treatment methods evaluated, five treatment methods were determined to be most feasible. Landowner valuation of environmental changes in the ecosystem brought on by Saltcedar is very important in the decision of which treatment method to implement. Personal valuation, over a period of ten years, will often determine which treatment methods are most cost efficient.
