ABSTRACT
The 1969 National Environmental Policy Act requires both the government and the private sector to “preserve important historic, cultural and natural aspects of our national heritage, and maintain, wherever possible, an environment which supports diversity and variety of individual choice.” After review by the California State Historic Preservation officer, the Advisory Council on Historic Preservation, and the US Department of the Interior, as well as professional, Native American, and public review and a public hearing, the management plan was incorporated into a memorandum of agreement, which the corps signed in 1976. During the late 1970s, new, more detailed studies were sponsored to determine what biological and cultural factors were associated with management of ethnobotanically important plants and how new preserve areas might be established. Because the plants were never cultivated by anyone other than Pomoan specialists, no body of horticultural information appeared to be in existence.
