U.S. DEPARTMENT OF THE INTERIORBUREAU OF LAND MANAGEMENT
A landscape approach looks across large, connected geographic areas to more fully recognize natural resource conditions and trends, natural and human influences, and opportunities for resource conservation, restoration, and development. It seeks to identify important ecological values and patterns of environmental change that may not be evident when managing smaller, local land areas.
A landscape approach uses this broader understanding of the environment to inform, focus, and integrate the BLM’s national and local resource management efforts. A landscape approach provides a framework for integrating science with management; for coordinating management efforts and directing resources where they are most needed; and for adapting management strategies and actions to changing conditions and new information. It also provides an important foundation for developing coordinated management strategies with partner agencies, stakeholders, and American Indian Tribes.
Why is the BLM developing a “landscape approach”?
The BLM recognizes that the public lands are facing increasingly complex and widespread environmental challenges that transcend traditional management boundaries. These challenges include managing wildfire; controlling weeds and insect outbreaks; providing for energy development and urban growth; and addressing pervasive impacts from the effects of climate change. The BLM is developing a landscape-scale management approach to better understand these challenges and support balanced stewardship of the diverse natural resources of the public lands.
How are landscapes defined?
Landscapes can be defined or classified in many ways. To gain a broader perspective on ecological values and trends, the BLM is using a landscape classification called ecoregions. More specifically, the BLM is using Level III ecoregions, which have been classified by the Commission for Environmental Cooperation and the Environmental Protection Agency as fundamental geographic units for resource assessment and management. Examples of Level III ecoregions include the Sonoran Desert, Central Basin and Range, and Colorado Plateau.
How do ecoregions relate to the BLM’s local field offices?
What is the role of the BLM’s local field offices in a landscape management approach?
The BLM’s field offices maintain their central role in managing public lands. They continue to prepare land use plans, authorize land uses, conduct monitoring, and work with partners and stakeholders to develop and implement local management strategies. The broader perspective provided through a landscape approach will help inform, focus, and integrate these local management efforts.
Is a landscape approach something new?
1. Rapid Ecoregional Assessments (REAs)
REAs synthesize the best available information about resource conditions and trends within an ecoregion. They highlight and map areas of high ecological value, including important wildlife habitats and corridors, and gauge their potential risks from climate change, wildfires, invasive species, energy development, and urban growth. REAs also map areas that have substantial energy development potential, and relatively low ecological value, which could be suited for siting future energy development. In addition, REAs establish landscape-scale baseline ecological data to gauge the effect and effectiveness of future management actions.
Ecoregions are large landscapes defined by their ecological characteristics. Since 2010, fourteen REAs have been initiated in ecoregions across the western U.S. and Alaska. The BLM first piloted REAs in three ecoregions: the Northern Great Basin, Wyoming Basin, and Chihuahuan Desert. In 2010, REAs were initiated for seven additional ecoregions: the Central Basin and Range, Mojave Basin and Range, Sonoran Desert, Northwestern Great Plains, Middle Rockies, and the Colorado Plateau in the continental U.S., and the Seward Peninsula-Nulato Hills-Kotzebue Lowlands in Alaska. These ecoregions vary in size from 11.5 million acres (Seward Peninsula ecoregion) to 88.3 million acres (Northwest Great Plains ecoregion). Two more REAs were initiated in 2011 for the Wyoming Basin and the Northern Basin and Range. In 2012, five REAs were initiated for the Yukon Kuskokwin and the North Slope in Alaska and the Madrean Archipelago, Chihuahuan Desert, and the Southern High Plains in the continental U.S.
2. Ecoregional Direction
Ecoregional Direction will use the results of the REAs, with input from BLM staff, partner agencies, stakeholders, and Tribes, to develop key management strategies for the public lands within an ecoregion. Ecoregional Direction will identify strategies for conservation and development, including focal areas for conserving wildlife habitats and migration corridors, and focal areas for potential energy development and transmission. Ecoregional Direction will also provide a blueprint for coordinating and implementing these priorities at the BLM’s state and field-office levels.

4. Monitoring for Adaptive Management
Consistent, high-quality monitoring information is essential for adaptive management. The BLM is modernizing its monitoring and mapping programs to meet this critical information requirement. The BLM’s Assessment, Inventory, and Monitoring (AIM) Strategy will standardize data collection and retrieval so information is comparable over time, and can be readily accessed and shared. The goal of the AIM Strategy is to provide the information needed to understand resource conditions and trends, and to evaluate and refine implementation actions. In addition, the BLM is implementing its Geospatial Services Strategic Plan, which will provide the high quality mapping products needed to develop and support resource management strategies and decisions.
5. Science Integration
What is the role of Landscape Conservation Cooperatives (LCCs) in the BLM’s landscape approach?
LCCs are management-science partnerships composed of private, state, Tribal, and Federal representatives who will work toward a shared vision of landscape health and sustainability. The LCCs will facilitate collaboration, provide science information and tools needed for developing resource management strategies, and promote coordinated partnership actions at the landscape and local levels. The LCCs and the BLM’s landscape approach are complementary efforts that will become more fully integrated as they progress.
