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.

This book was released on 2020-03-03 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first comprehensive environmental history of California’s Great Central Valley, where extensive freshwater and tidal wetlands once provided critical habitat for tens of millions of migratory waterfowl. Weaving together ecology, grassroots politics, and public policy, Philip Garone tells how California’s wetlands were nearly obliterated by vast irrigation and reclamation projects, but have been brought back from the brink of total destruction by the organized efforts of duck hunters, whistle-blowing scientists, and a broad coalition of conservationists. Garone examines the many demands that have been made on the Valley’s natural resources, especially by large-scale agriculture, and traces the unforeseen ecological consequences of our unrestrained manipulation of nature. He also investigates changing public and scientific attitudes that are now ushering in an era of unprecedented protection for wildlife and wetlands in California and the nation.
