Description:
Abstract: This feature class includes monitoring data collected nationally to understand the status, condition, and trend of resources on BLM lands. Data are collected in accordance with the BLM Assessment, Inventory, and Monitoring (AIM) Strategy. The AIM Strategy specifies a probabilistic sampling design, standard core indicators and methods, electronic data capture and management, and integration with remote sensing. Attributes include the BLM aquatic core indicators: pH, conductivity, temperature, pool depth, length, frequency, streambed particles sizes, bank stability and cover, floodplain connectivity, large woody debris, macroinvertebrate biological integrity, ocular estimates of vegetative type, cover, and structure and canopy cover. In addition, the contingent indicators of total nitrogen and phosphorous, turbidity, bank angle, thalweg depth profile and quantitative vegetation estimates (see Entity/Attribute Section for exact details on attributes). Data were collected and managed by BLM Field Offices, BLM Districts, and/or affiliated field crews with support from the BLM National Operations Center. Data are stored in a centralized database (AquADat) at the BLM National Operations Center.
Purpose: This dataset was created to monitor the status, condition and trend of national BLM resources in accordance with BLM policies. The methodology used for the collection of these data can be found in TR 1735-2 (AIM National Aquatic Monitoring Framework: Field Protocol for Wadeable Lotic System). These data should not be used for statistical or spatial inferences without knowledge of how the sample design was drawn or without calculating spatial weights for the points based on the sample design.

Process Description: Data were collected by trained field crews with the BLM and partner organizations. They followed the BLM core aquatic core and contingent indicators in TR 1735-2 (AIM National Aquatic Monitoring Framework: Field Protocol for Wadeable Lotic System). Data were captured electronically using the Stream And River Assessment Hub (SARAH). They were managed by the data collectors, with oversight from BLM field offices, state offices, and the National Operations Center. This dataset has undergone rigorous QA/QC to ensure data quality.

Attribute Definition: This field indicates whether or not the site's environmental gradients were within the range of experience of the model. A fail indicates the model potentially had to extrapolate, rather than interpolate, to accommodate one or more of the habitat variables.
