 The LWCF has a broad-based coalition of support and oversight, including the National Parks Conservation Association, Environment America, The Wilderness Society, the Land Trust Alliance, the Nature Conservancy, the National Wildlife Federation, and The Conservation Fund.The primary source of income to the fund is fees and royalties paid to the Bureau of Ocean Energy Management, Regulation and Enforcement by oil and gas drilling offshore in federal water for oil and gas.Congress regularly diverts most of the funds from this source to other purposes, however.
