Describes a ranking system used to evaluate the potential invasiveness and impacts of 113 non-native plants to natural areas in Alaska. Species are ranked by a series of questions in four broad categories: ecosystem impacts, biological attributes, distribution, and control measures. Also included is a climate screening procedure to evaluate the potential for establishment in three ecogeographic regions of Alaska [Juneau, Fairbanks, Nome].

Full-color illustrated photographs of over 175 species of invasive plants in North America that describes their environmental and economic impact.

Now back in print. Plants of Western New South Wales grew from the long experience and expertise which the authors acquired during their employment with their respective organisations in the arid and semi-arid pastoral areas of the State. Each author became aware of the need for a comprehensive record illustrating and describing the great array of plants in the area. The need was identified both for people involved in research and advisory services, and particularly for the landholders who need to manage the plants for their livelihood. The book is a landmark because it draws together all of the existing knowledge of plants from the area, adds to it the extensive collections and research of the authors and presents the whole as a comprehensive collation and description of the plants of the dry pastoral portion of the State. Because of its comprehensive nature, the work is significant to pastoralists and people concerned with plants throughout Australia. The 1992 edition of Plants of Western New South Wales has been reprinted and published by CSIRO PUBLISHING with a one page appendix giving website addresses of various herbaria in Australia where the reader can readily access up-to-date information on botanical name changes.

INVASIVE ALIEN SPECIES Invasive Alien Species: Observations and Issues from Around the World Volume 1: Issues and Invasions in Africa Invasive alien species are spreading into new ecosystems each year. The impacts caused by these invaders can be swift and devastating. The topic of invasive alien species is large, complex, and globally significant at various scales, exacerbated by the globalization of world economies and increased trade and commerce that has overcome natural barriers to species movement. Invasive alien species threaten global food supplies, water quality and availability, and energy production and delivery. With the added risks associated with global climate change, the global homogenization of plants, animals, and microbes is a major factor in the decline in ecosystem health and ecosystem services worldwide. To counter this trend, there is a critical need to unify governments, cultures, and programs to improve cross-boundary coordination to effectively address the wide range of invasive alien species threats to the environment, economies, and to plant and animal health; particularly human health. This 4-volume work is the first to compile a set of useful material for key topics, to provide a better understanding of the overall global threat of invasive alien species and the diverse array of problems faced around the world, and assemble material that includes potential replicable solutions to overcome these threats. The books also highlight the threat posed by invasive alien species in terms of a global ‘call to action’. Since invasive species know no boundaries, it is our hope that by compiling material from different scientific and social perspectives around the world, and sharing knowledge and examples of a diverse array of associated topics, we can advance global awareness and improve unified national responses to the threat posed by invasive alien species.
