  • This book, now in its third edition, began almost 25 years ago when Weed Ecology: Implications for Vegetation Management was published in 1984. That text concentrated on the need for farmers, foresters, rangeland managers, and the researchers who advised them to understand better the biology of weeds and the role people play in creating and maintaining weeds in agriculture and other production systems. We were assisted in that first effort by the writings of many early scientists, such as J. L. Harper, H. G. Baker, and E. J.

  • The study of wetland plants has been of interest to botanists for many years, but the need to identify and understand these plants has expanded dramatically since the 1970s. At that time, ecologists began to make known the vital role that wetlands play in our landscapes. The image of wetlands has shifted from that of mosquito-ridden wastelands to natural areas of critical importance. Because the field of wetland ecology has expanded, so has the study of the plants that thrive there, and their role in ecosystem dynamics.

  • The idea for this book arose during the planning phases of an International Conference in Edmonton, Canada in July 2004 entitled “The Science of Changing Climates — Impacts on Agriculture, Forestry and Wetlands.” The conference was organized jointly by the Canadian Societies of Animal Science, Plant Science and Soil Science with support from Natural Resources Canada/Canadian Forest Service because they saw climate change as one of the most serious environmental problems facing the world....

  • Evidence grows daily of the rapid changes in climate due to human activities and their impact on plants and animals. Plant function is inextricably linked to climate and atmospheric carbon dioxide concentration. On the shortest and smallest scales the climate affects the plant’s immediate environment and thus directly influences physiological processes. On longer and larger time and space scales climate influ- ences species distribution and community composition and determines what crops can be viably produced in managed agricultural, horticultural and forestry ecosys- tems.

  • Visiting a nice lake is like going to a grocery store that has everything. But what happens if the lake is lacking an item or two? Maybe one or more lake projects can address the need. Although this book has several hundred project ideas, many of them are updated project ideas that have been previously conducted one way or another. For example, dredging has been occurring for over 4000 years. Fish culture, aquatic plant management (using handpulling techniques), and waste disposal are also thousands of years old....

  • The names Bloch and Geitner are synonymous with machinery maintenance and reliability for process plants. They save companies like Dow and Equilon millions of dollars a year by extending the life of rotating machinery in their plants. Extending the life of existing machinery is the name of the game in the process industries, not designing new machinery. This series by Bloch and Geitner was the first and is still the best, most comprehensive source for doing just that.

  • The science of ecology and the practice of management are critical to our understanding of the Earth’s ecosystems and our efforts to conserve them. This book attempts to bridge the gap between ecology and natural resource management and, in particular, focuses on the discipline of plant ecology as a foundation for vegetation and wildlife management. It describes how concepts and approaches used by ecologists to study communities and ecosystems can be applied to their management. Guy R.

  • The living organism which will be deeply affected are shredders, which feed on coarse sedimentary detritus, and collector-gatherers, which feed on fine sedimentary detritus, were the macroinvertebrate functional feeding groups are most adversely affected. Furthermore, during the industrial process, high amount of hydrofluoric acid (HF) are used to separate different sandy materials which are subsequently used for manufacturing glass at industrial plants. Therefore, high concentration of fluoride ion and suspended inorganic matter discharged by the industrial into the study site....

  • This book is about the conservation of genetic diversity of wild plants in situ in their natural surroundings, primarily in existing protected areas but also outside conventional protected areas. A lot of effort has been dedicated to conserving plant biodiversity, but most of this has focused on rare plant communities or individual species threatened with extinction.

  • The timing of the publication of this book couldn’t be better as we celebrate the 50th anniversary of Charles Elton’s seminal book, The Ecology of Invasions by Animals and Plants. Since this influential book was published in 1958, the study of bioinvasions has developed exponentially, alongside the exponential growth in the magnitude of the invasion problem itself. Today, bioinvasion, a highly complex ecological process and environmental concern, has become a specific branch in ecology and environmental studies, with many disciplines developing within it....

  • To be effective, risk management needs to be an ongoing and meaningful element in the management of the plan. The plan needs to do more than a ‘tick and flick’ exercise at the commencement of the project; it needs to identify who is responsible for reviewing risks on a regular basis, and how this will be done.

  • The success of the implementation of a New Policy Proposal will be judged in terms of the benefits delivered – i.e. the measurable improvements resulting from outcomes which are perceived as an advantage by stakeholders. From the moment the first elements of change are introduced into the operations of a department or agency and on-the-ground in the public arena, expectations will be met or not met.

  • A project has discrete steps budgeted into time, and it is in finite steps that project management can go awry. Someone who has never run the kind of project being detailed is likely to assign steps and values that are unrealistic. Therefore, project management is best done by someone who has completed a similar project before and knows the steps that go into it. Like many management principles, project management isn’t new. Henry Laurence Gantt, a mechanical engineer and disciple of scientific management first published the Gantt chart in 1910.

  • Despite a variety of processes and the availability of raw-material sources, the widespread utilisation of annual plants in pulping has not been technically or economically feasible in Western countries due to the lack of a simple and environmentally efficient pulping method and the problems associated with raw material storage and logistics. An ideal non-wood pulping process is simple and environmentally efficient and can be applied on a small scale.

  • There has been a steady increase in anthropogenic pressure over the past few years due to rapid industrialization, urbanization and population growth, causing frequent environmental hazards. Threats of global environmental change, such as climate change and sea level rise, will exacerbate such problems. Therefore, appropriate policies and measures are needed for management to address both local and global trends.

  • Biological invasions are one of the major threats to our native biodiversity. The magnitude of biodiversity losses, land degradation and productivity losses of managed and natural ecosystems due to invasive species is enormous. It has an adverse impact on our efforts to maintain biodiversity and on our conservation programs, and thus could create societal instability.
