Sago is easily cultured in pure liquid media in the laboratory but is also a nuisance plant that clogs irrigation facilities and interferes with fishing and recreational boating. These attributes have resulted in much information on sago physiology and control methodology that can be useful to waterfowl managers. In addition, there are numerous references to use of sago by waterfowl and to methods whereby sago production can be increased to attract greater numbers of waterfowl. There have been no recent attempts to assemble and synthesize the available information on sago, despite its nearly worldwide ecological importance. I have tried to assemble such information in this report so that sago can be properly protected and managed.
Some material is included that is possibly of interest only to specialists.
This report is largely based on material in English or with English summaries, but much foreign material, often not seen by me but cited by other authors, is included. Not included are many references to the simple occurrence of sago in various wetlands worldwide, early taxonomic studies, mostly foreign, of sago, and reports of tests of potential chemical control agents.
