Biological Control of Weeds in Australia


Book Description

Biological control of weeds has been practiced for over 100 years and Australia has been a leader in this weed management technique. The classical example of control of prickly pears in Australia by the cactus moth Cactoblastis cactorum, which was imported from the Americas, helped to set the future for biocontrol of weeds in many countries. Since then there have been many projects using Classical Biological Control to manage numerous weed species, many of which have been successful. Importantly, there have been no serious negative non-target impacts - the technique, when practiced as it is in Australia, is safe and environmentally friendly. Economic assessments have shown that biocontrol of weeds in Australia has provided exceedingly high benefit-to-cost ratios. This book reviews biological control of weeds in Australia to 2011, covering over 90 weed species and a multitude of biological control agents and potential agents. Each chapter has been written by practicing biological control of weeds researchers and provides details of the weed, the history of its biological control, exploration for agents, potential agents studied and agents released and the outcomes of those releases. Many weeds were successfully controlled, some were not, many projects are still underway, some have just begun, however all are reported in detail in this book. Biological Control of Weeds in Australiawill provide invaluable information for biological control researchers in Australia and elsewhere. Agents used in Australia could be of immense value to other countries that suffer from the same weeds as Australia. The studies reported here provide direction to future research and provide examples and knowledge for researchers and students. KEY FEATURES * A unique collation of information for Australian weed research and management * Contains all the information about biological control of weeds in Australia in one book * Provides key references for further information * Will become a well cited publication




Flora of the Hunter Region


Book Description

The Hunter Region, between the Hawkesbury and Manning rivers in eastern New South Wales, hosts a rich diversity of vegetation, with many species found nowhere else. Spanning an area from the coast to the tablelands and slopes, its rainforests, wet and dry sclerophyll forests, woodlands, heathlands, grasslands and swamps are known for their beauty and ecological significance. Flora of the Hunter Region describes 54 endemic trees and large shrubs, combining art and science in a manner rarely seen in botanical identification guides. Species accounts provide information on distribution, habitat, flowering, key diagnostic features and conservation status, along with complete taxonomic descriptions. Each account includes stunning botanical illustrations produced by graduates of the University of Newcastle's Bachelor of Natural History Illustration program. The illustrations depict key diagnostic features and allow complete identification of each species. This publication will be a valuable resource for those interested in the plants of the region, including researchers, environmental consultants, horticulturalists and gardeners, bush walkers, herbaria, and others involved in land management.

Wildflowers of the Brisbane Ranges


Book Description

The Brisbane Ranges area, situated 80 km west of Melbourne and 30 km north-west of Geelong, is extraordinarily rich in diversity. With basalt grasslands, heathy woodland, alluvial soils, buckshot gravel and granite rocks, it boasts more than 430 species of native plants. Wildflowers of the Brisbane Ranges contains magnificent photographs of more than 400 species, many of them orchids, including rare and vulnerable species such as the Naked Sun Orchid (Thelymitra circumsepta) and the Hyacinth Orchid (Dipodium pardalinum). A list of references, colour guide, glossary, comprehensive index and a soil type map have been included, to assist the reader in locating and identifying the different species. This full colour guide is the culmination of more than a decade of painstaking observation. It will help both the casual visitor and the keen naturalist to locate and identify an extensive range of wildflowers from this exceptional part of Victoria.
