The Bureau of Land Management (BLM) administers approximately 245 million acres of our public lands and yet, for most of our nation鈥檚 history, these lands seemed largely destined to end up in private hands.聽 Even when the Taylor Grazing Act of 1934 ushered in an important era of better managing public grazing districts and 鈥減romoting the highest use of the public lands,鈥� such use of our public lands still was plainly considered temporary, 鈥減ending its final disposal.鈥� It was not until 1976 with the passage of the Federal Land Policy and Management Act (FLPMA) that congress adopted a policy that the 鈥減ublic lands be retained in Federal ownership.鈥澛� 聽In the 40 years since Congress enacted FLPMA, the BLM has experienced a remarkable transformation from an agency once focusing almost entirely on livestock grazing and mineral development to one that has fully embraced a multiple use mandate鈥攊ncluding managing large tracts of public lands for conservation and even wilderness protection purposes.聽 Many of the nation鈥檚 prominent environmental or natural resource laws, within the last few years, have celebrated their 40thanniversaries, often provoking critical dialogues about their past and future.聽 It is now time to acknowledge and celebrate the remarkable transformation of the BLM over the last 40 years since FLMPA鈥檚 enactment in 1976. As the Trump Administration鈥檚 priorities unfold, we address the implications of potential policy shifts and other emerging issues in these critical areas.
