Assessment, Inventory, and Monitoring (AIM)

The Assessment, Inventory, and Monitoring (AIM) Strategy provides a framework for the BLM to quantitatively assess the condition, trend, amount, location, and spatial pattern of natural resources on the nation's public lands. Monitoring information collected following the AIM Strategy can be used many times, to answer many questions, across different programs, and in conjunction with other agencies. For more information about implementing the AIM Strategy, please visit the AIM Landscape Toolbox website.

Terrestrial and Aquatic Indicator Data

Consistent data that can serve many monitoring objectives and can also be aggregated for use across multiple scales of management are a valuable asset for the BLM. The standardized terrestrial and aquatic (streams and rivers) ecosystem measurements (or indicators) collected under the AIM Strategy are shown in the table to the right.

Terrestrial and aquatic indicator data are being applied to inform management of BLM lands across multiple programs from Arizona to Alaska (see map below). Download these terrestrial data and supporting documentation here, and contact AIM Data Manager, Sarah Burnett, with questions at Aquatics data will be forthcoming: please contact Scott Miller for more information at
