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 Interpreting Indicators for Rangeland Health (IIRH) method. The IIRH method is a qualitative assessment of rangeland health, defined as "the degree to which the integrity of the soil, vegetation, water, and air, as well as the ecological processes of the rangeland ecosystem are balanced and sustained." Attributes include the final rating for IIRH indicators: hydrologic function, biotic integrity, and soil/site stability (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 (TerrADat) 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 on landscapetoolbox.org and the Monitoring Manual, 2nd Edition. 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 Step:
Process Description: Data were collected by trained data collectors with the BLM and partner organizations. They followed the BLM Interpreting Indicators of Rangeland Health protocols (http://www.blm.gov/nstc/library/pdf/1734-6rev05.pdf). Data were captured electronically using the Database for Inventory, Monitroing, and Assessment (http://jornada.nmsu.edu/monit-assess/dima). 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.

Entity and Attribute Information:
Overview Description:
Entity and Attribute Overview: Entities are broad data types and attributes are specific AIM indicators collected at points across a diversity of BLM lands for a variety of purposes. Attributes include basic plot info as well as AIM core indicators: bare ground, vegetation composition, plant species of management concern, proportion of site in large, intercanopy gaps, soil stability, vegetation height and non-native invasive species. Entities (points) were chosen using a probabilistic sample design.
Entity and Attribute Detail Citation: BLM Technical Note 440: Core Terrestrial Indicators and Methods (MacKinnon et al. 2011)
Detailed Description:
Entity Type:
Entity Type Label: Attributes of Rangeland Health Summarized by Monitoring Location
Entity Type Definition Source: Interpreting Indicators of Rangeland Health (Pellant et al. 2005)
Entity Type Definition: Qualitative assessment of rangeland health, defined as "the degree to which the integrity of the soil, vegetation, water, and air, as well as the ecological processes of the rangeland ecosystem are balanced and sustained."
Attribute:
Attribute Label: SiteID
Attribute Definition: This is used by data collectors for grouping plots, e.g., by type or management area. Common values are names of management units (such as allotments) or the subject of data collection (such as reclamation).
Attribute:
Attribute Label: ProjectName
Attribute Definition: Refers to the broader project area the data was collected in. Generally includes the state, BLM management office and year.
Attribute:
Attribute Label: Ecological Site ID
Attribute Definition: Unique ID referring to the ecological site, defined by NRCS as "a distinctive kind of land with specific characteristics that differs from other kinds of land in its ability to produce a distinctive kind and amount of vegetation." ID's are from the Ecological Site Information System (https://esis.sc.egov.usda.gov/About.aspx).
Attribute:
Attribute Label: Plot ID
Attribute Definition: Name for each location or "plot" where data is collected, as assigned by the data collector. Formats vary. Duplicate Plot ID's may exist among different Sites and Projects, but not within the same Site. Each AIM plot is the center point of a 55-meter radius (110-meter diameter) circle in which monitoring indicators (data set attributes) were collected. Points were randomly selected using a spatially balanced sampling design within the desired inference space. Most of the attributes were collected along three, 50- or 25-meter transects, offset from the center point by 5 meters, radiating out from the center point at 0, 120, and 240 degrees.
Attribute:
Attribute Label: PlotKey
Attribute Definition: Unique numeric ID associated with each plot location. This is automatically generated in DIMA the first time the plot is created. Future visits to the same plot generally use the same PlotKey.
Attribute:
Attribute Label: Latitude
Attribute Definition: The latitude of the plot location.
Attribute:
Attribute Label: Longitude
Attribute Definition: The longitude of the plot location.
Attribute:
Attribute Label: DateEstablished
Attribute Definition: The date the plot was established in DIMA.
Attribute:
Attribute Label: DateVisited
Attribute Definition: The date that data were collected at the plot.
Attribute:
Attribute Label: Hydrologic Function Rating
Attribute Definition: Rating of the Hydrologic Function attribute of rangeland health. Hydrologic function is defined as the capacity of an area to caputre, store, and safely release water from rainfall, run-on, and snowmelt (where relevant), to resist a reduction in this capacity, and to recover this capacity where a reduction does occur. Ratings refer to the departure from reference conditions, and fall into five categories: none-to-slight, slight-to-moderate, moderate-to-extreme, and extreme-to-total.
Attribute:
Attribute Label: Biotic Integrity Rating
Attribute Definition: Rating of the Biotic Integrity attribute of rangeland health. Biotic integrity is defined as the capacity of the biotic community to support ecological processes within the normal range of variability expected for the site, to resist a loss in the capacity to support these processes, and to recover this capacity when losses do occur. The biotic community includes plants, animals, and microorganisms occurring both above and below ground. Ratings refer to the departure from reference conditions, and fall into five categories: none-to-slight, slight-to-moderate, moderate-to-extreme, and extreme-to-total.
Attribute:
Attribute Label: Soil & Site Stability Rating
Attribute Definition: Rating of the Soil & Site Stability attribute of rangeland health. Soil & Site Stability is defined as the capacity of an area to limit redistribution and loss of soil resources (including nutrients and organic matter) by wind and water. Ratings refer to the departure from reference conditions, and fall into five categories: none-to-slight, slight-to-moderate, moderate-to-extreme, and extreme-to-total.
Attribute:
