Book Description
The invasion by non-native saltcedar (Tamarix L. spp.) has caused enormous damage on native plant and animal communities, especially in riparian ecosystems in areas of the western United States. The main methods of control currently used, mechanical, chemical and manual, have proven to be enormously expensive. In the last few years, biological control using an introduced leaf-eating beetle, Diorhabda elongata, has shown a very high potential for success. Success stories of biological control include saltcedar stands along the Humboldt River in Lovelock, Nevada where this beetle defoliated about 5,000 acres of saltcedar. The Colorado Noxious Weed Act of 1996, the State Weed Law and two bills passed by the 108th Congress have enabled county, city and state governments to utilize and implement management programs to target saltcedar. The intent of this research was to monitor and examine the effects of the chemical and mechanical treatments of saltcedar in Fremont County, Colorado. The results of this research indicate that chemical control has had a significant impact on killing saltcedar from pre-treatment status to post-one-year and post-two-year status. It was found that the Hydroaxe control method cleared areas of stands of saltcedar but new growth appeared form below the cut stump of the plant. Protocol for herbicide control, according to the manufacturer's label, recommends that treated areas should be left undisturbed for approximately three years after application.

Book Description
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Book Description
Encyclopedia of the Anthropocene, Five Volume Set presents a currency-based, global synthesis cataloguing the impact of humanity’s global ecological footprint. Covering a multitude of aspects related to Climate Change, Biodiversity, Contaminants, Geological, Energy and Ethics, leading scientists provide foundational essays that enable researchers to define and scrutinize information, ideas, relationships, meanings and ideas within the Anthropocene concept. Questions widely debated among scientists, humanists, conservationists, politicians and others are included, providing discussion on when the Anthropocene began, what to call it, whether it should be considered an official geological epoch, whether it can be contained in time, and how it will affect future generations. Although the idea that humanity has driven the planet into a new geological epoch has been around since the dawn of the 20th century, the term ‘Anthropocene’ was only first used by ecologist Eugene Stoermer in the 1980s, and hence popularized in its current meaning by atmospheric chemist Paul Crutzen in 2000. Presents comprehensive and systematic coverage of topics related to the Anthropocene, with a focus on the Geosciences and Environmental science Includes point-counterpoint articles debating key aspects of the Anthropocene, giving users an even-handed navigation of this complex area Provides historic, seminal papers and essays from leading scientists and philosophers who demonstrate changes in the Anthropocene concept over time
