Welcome to the Ecological Site Description (ESD) System
for Rangeland and Forestland Data



Anyone may view reports of approved Ecological Site Descriptions. To view the various reports select a State or MLRA or both and Submit. From the subsequent list, select the ESD you wish to view.

Major Land Resource Areas (MLRA) are a portion of the spatial framework utilized by the Natural Resources Conservation Service in the planning, design, implementation, and evaluation of natural resource management activities. MLRA boundaries reflect nearly homogenous areas of landuse, elevation, topography, climate, water resources, potential vegetation, and soils.

If you need assistance in locating the MLRA, click on the MLRA Explorer link below. The MLRA Explorer is an interactive map-based application of USDA Agriculture Handbook 296. With the tools in this application, you can:
(1) search for your MLRA by entering your State and County
(2) search for LRRs and MLRAs using a variety of geographical and textual queries.

ESIS Status Definitions:

Provisional: an ESD at the provisional status represents the lowest tier of documentation that is releasable to the public. It contains a grouping of soil units that respond similarly to ecological processes. The ESD contains 1) enough information to distinguish it from similar and associated ecological sites and 2) a draft state and transition model capturing the ecological processes and vegetative states and community phases as they are currently conceptualized. The provisional ESD has undergone both quality control and quality assurance protocols. It is expected that the provisional ESD will continue refinement towards an approved status.

Approved: an ESD at the approved status represents a tier of documentation that fully describes all distinguishing features of the ecological site, to include both tabular and narrative entries. The reference state and community phase in the state and transition model is fully described, including both tabular and narrative entries. All other alternative states are at least described in narrative form. The approved ESD has undergone both quality control and quality assurance protocols.

Correlated: an ESD at the correlated status represents the highest tier of documentation for an ecological site. The ESD fully describes all distinguishing features of the ecological site, to include both tabular and narrative entries. All vegetative states and community phases in the state and transition model are completely documented, including both tabular and narrative entries. An interpretations section is prepared to help users apply the ESD for planning purposes. The correlated ESD has undergone both quality control and quality assurance protocols.
