Available in PDF, EPUB and Kindle. Book excerpt: Sago pondweed is a submerged macrophyte of nearly cosmopolitan distribution. The plant is of worldwide importance as a waterfowl food but also can be a nuisance in irrigation canals and recreational areas. Future research should concentrate on (1) determining, in a variety of wetland types, the causes of light-limiting turbidity that often suppresses sago growth, (2) understanding the ways in which human activities on and near wetlands affect sago production, and (3) developing reliable and predictable techniques to stimulate sago production for waterfowl by using water level manipulations and other means, in a variety of environmental settings.

Download or read book Plants of Western New South Wales written by G. M. Cunningham and published by CSIRO PUBLISHING. This book was released on 2011-07-28 with total page 768 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
