BLM Ignores Own Findings in Proposed Management Plans

Millions of acres of Western public lands could lose protections

BLM Ignores Own Findings in Proposed Management Plans
Tony Bynum


The Bureau of Land Management (BLM) oversees a quarter-billion acres of public lands across the nation. Every two decades, the agency revises its management plans for each of the more than 100 planning areas—designated regions that it oversees. In mid-2019, BLM released six draft plans that will guide management of more than 20 million acres for the next 20 to 30 years. The Pew Charitable Trusts reviewed the plans and found troubling trends within agency-preferred alternatives—the course BLM says it is most likely to take— that could result in the loss of protection for millions of acres of public land: The proposals would fail to conserve lands that the agency’s own research has deemed worthy of protection,1 cut decades-old safeguards, minimally protect a fraction of 1 percent of the areas found to contain wilderness characteristics, and open vast swaths of public lands to energy and mineral development.

Federal law requires BLM to consider special management, including prioritizing the designation and protection of areas of critical environmental concern (ACECs), for lands that have special fish and wildlife, archaeological, and unique values. However, the 2019 drafts feature far fewer ACECs designations than the agency’s findings of lands that meet the criteria warrant and propose to eliminate ACECs that have been in place for decades.2 (See Table 1.)

As with ACECs, a large gap exists between BLM’s findings for lands with wilderness characteristics (LWCs)—natural places that provide excellent opportunities for solitude or primitive, unconfined recreation—and how many of these lands are included for adequate management in the draft plans: Less than 1 percent of agency-identified LWCs would be managed to protect these values under the BLM drafts.

Agenda for America

A collection of resources to help federal, state, and local decision-makers set an achievable agenda for all Americans

Quick View

Data-driven policymaking is not just a tool for finding new solutions for emerging challenges, it makes government more effective and better able to serve the public interest. In the coming months, President Joe Biden and the 117th Congress will tackle a number of environmental, health, public safety, and fiscal and economic issues—nearly all of them complicated by the COVID-19 pandemic. To help solve specific, systemic problems in a nonpartisan fashion, Pew has compiled a series of briefings and recommendations based on our research, technical assistance, and advocacy work across America.

Data-driven policymaking is not just a tool for finding new solutions for difficult challenges. When states serve their traditional role as laboratories of innovation, they increase the American people’s confidence that the government they choose—no matter the size—can be effective, responsive, and in the public interest.
