The AIM Strategy implements standard data collection and storage so that information is readily accessed, aggregated and shared. This is accomplished through electronic, onsite data capture and centralized data management through BLM’s national geospatial infrastructure.
Internal Data Access (for those with DOI Credentials): AIM Data Portal
External Data Access (for those without DOI Credentials): BLM’s Landscape Approach Geoportal.
Access Terrestrial AIM Data
Information about terrestrial ecosystems is stored in two databases at the BLM National Operations Center. TerrADat, or the Terrestrial AIM Database, houses all BLM terrestrial monitoring data collected by states and field offices. LMF, or the Landscape Monitoring Framework database, contains the BLM terrestrial monitoring data collected for national assessments.
For terrestrial AIM data questions, please contact the AIM Data Manager, Sarah Burnett (email@example.com).
Access Lotic AIM Data
AquADat (Lotic AIM Database) is the BLM database that stores Lotic AIM indicator values for all sampled locations since 2013. AquADat allows users to access data via the BLM intranet, rather than having to request it through NAMC. Over 60 indicators are reported in AquADat resulting from field collection of the core, contingent or covariate field methods. The large number of indicators results from the fact that many indicators can be computed from one field method. For example, AquADat contains five different stream bed particle size indicators that are all derived from field pebble counts.
Indicators in AquAdat are organized from left to right in the following groups: site descriptors, biodiversity and riparian habitat quality indicators, water quality indicators, watershed function and instream habitat indicators, and lastly covariates (e.g., slope). Metadata about AquADat and a brief description of each indicator can be found here and more detailed indicator metadata, computation, and application information can be found here. All data within AquADat has gone through QC by field crews, project leads, and the NOC/NAMC, as detailed in the Lotic Data Management Protocol. More detail about NOC/NAMC QC procedures is forthcoming.
AquADat is also available to the public via the BLM’s Landscape Approach Geoportal. For aquatic AIM data questions, please contact NAMC’s aquatic analyst Jennifer Courtwright (firstname.lastname@example.org).
AquADat will be updated with Aquatic AIM data from 2017 in February of 2018. If you have immediate 2017 data needs prior to February, please contact Jennifer Courtwright (email@example.com). For future field seasons, we hope to have preliminary computed aquatic indicators available using an online interface immediately after data collection.
