Expert Witness for Arboricultural, Landscape, Nursery Values and Conditions
The number of storms in recent years increases the need for better tree and landscape decisions for property owners. Research regarding landscape damages for different storm intensities, what plants get knocked down by winds more often, and priorities for landscape restoration have been intensified by many southern state universities' forestry and horticultural departments.
Trees and landscapes have been valued since humans were given gardens for food and enjoyment. Once people determined how to harvest seeds, how to plant gardens and landscapes, and how to relocate trees and plants, then decisions about what to use and what not to use began to set values for plants. It is this author's opinion that these practices logically date back to the beginning of history.
The value of a tree can only be determined if we agree. Any value given, whether by a layperson or a professional, is real when another person involved in the process agrees to that value. The value used in the final decision can also be a different value from the one determined by the experts who worked on it (especially when the experts worked on different sides of a valuation case).

Resistance to conventional pesticides has been growing rapidly among all pests. Furthermore, there is increased public concern about the safety of conventional pesticides, and increased governmental restrictions have resulted in the need to identify new compounds that are safe and effective in controlling pests that are of concern to agriculture as well as to public and animal health. Biopesticides may aid in the control of such pests with fewer deleterious effects to the environment, people and animals.
This volume and the contributed chapters therein are a result of the Natural Products for Pest Management symposium held at the 244th ACS National Meeting in Philadelphia, PA August 19-23, 2012 to honor the late Horace (Hank) Cutler and his contributions in the field of natural products chemistry. The symposium introduced recent discoveries and applications of natural products from insect, terrestrial plant, microbial, and synthetic sources for the management of insects, weeds, plant pathogenic microbes, and nematodes.
The first compilation of research on microbial degradation of contaminants in the rhizosphere. Discusses the interactions between microorganisms, plants, and chemicals in the rhizosphere. Examines the degradation of industrial chemicals, including polycyclic aromatic hydrocarbons, pentachlorophenol, and trichloroethylene, as well as the degradation of pesticides in the rhizosphere.
This new volume offers comprehensive information on microbial adaptation for pesticide degradation. Among the many topics covered in its 20 chapters are a general description of enhanced biodegradation as it occurs in an agricultural context; the microbial aspects of enhanced biodegradation, including the genetics, biochemistry, and ecology of pesticide-degrading microorganisms; and the potential impact of enhanced degradation on pesticide fate in aquatic systems and groundwater.
