the California Desert CONSERVATION AREA PLAN 1980 as amended U.S. DEPARTMENT OF THE INTERIOR BUREAU OF LAND MANAGEMENT U.S. Department of the Interior Bureau of Land Management Desert District Riverside, California the California Desert CONSERVATION AREA PLAN 1980 as Amended IN REPLY REFER TO United States Department of the Interior BUREAU OF LAND MANAGEMENT STATE OFFICE Federal Office Building 2800 Cottage Way Sacramento, California 95825 Dear Reader: Thank you.You and many other interested citizens like you have made this California Desert Conservation Area Plan. It was conceived of your interests and concerns, born into law through your elected representatives, molded by your direct personal involvement, matured and refined through public conflict, interaction, and compromise, and completed as a result of your review, comment and advice. It is a good plan. You have reason to be proud. Perhaps, as individuals, we may say, “This is not exactly the plan I would like,” but together we can say, “This is a plan we can agree on, it is fair, and it is possible.” This is the most important part of all, because this Plan is only a beginning. A plan is a piece of paper-what counts is what happens on the ground. The California Desert Plan encompasses a tremendous area and many different resources and uses. The decisions in the Plan are major and important, but they are only general guides to site—specific actions. The job ahead of us now involves three tasks: —Site-specific plans, such as grazing allotment management plans or vehicle route designation; —On-the-ground actions, such as granting mineral leases, developing water sources for wildlife, building fences for livestock pastures or for protecting petroglyphs; and —Keeping people informed of and involved in putting the Plan to work on the ground, and in changing the Plan to meet future needs. The overriding concern expressed by all of you during Plan development was, “Will it be implemented? Can BLM do what the Plan says it will do?” That is up to you. The CDCA Plan, in response to public concern and Congressional mandate, provides a way for respon- sible citizens to share in the use and enjoyment of desert resources that belong to all the people of the United States. It is a statement of management guidance designed to be useful today and it contains an amendment process so that it is adaptable to tomorrow. It will be effective if responsible citizens make it work. It will require the commitment of time, energy, money, and understanding from you, from all of us, if it is to become a reality on the ground. I do not know if what will happen, but I do know that the only way it can be done is with the full involve- ment of all the people: State and county agencies, businesses, user groups, and concerned individuals, all working together to do the job. Managing the public lands in the California Desert in a spirit of service, productivity, and concern for the public interest is the foundation upon which the implementation of the Desert Plan is based. To do this, the dedicated professional men and women of the Bureau of Land Management are committed to work for you and with you, the owners of the public lands in the California Desert Conservation Area.
