• Guiding Principles:• ESD are public documents• ESD is the framework upon which much of
NM ecological communication is based. “Lingua franca”
• ESD are in competition or complimentary with other ecological classification systems for usage. (Plant Associations, ECS, …)
• ESD has the advantage of containing predictive State and Transition Models.

• NM-ESD Core Group provides recommendations on ESD implementation strategies and priorities.
• Core Group Meeting Minutes URL:• http://usda-ars.nmsu.edu/esd• NRCS policy requires that ESD data be
stored at Ecological Site Information System (ESIS) web site, URL:
• http://esis.sc.egov.usda.gov/

• By NRCS policy ESD are to be data based and displayed in Electronic Field Office Tech Guide (EFOTG) URL: http://www.nrcs.usda.gov/technical/efotg/
• Section 2 of the EFOTG has a sub category for ESD. This JavaScript based display of ESD is frustrating and confusing for users.

NM Ecological Site Description StrategyNM Ecological Site Description Strategy NM opted for more user friendlinessNM opted for more user friendliness
• Core Group asked for a map based display of ESD choices.
• Some users are visual and some are tabular oriented so choices are displayed both ways.
• ESD has a long history of widespread use in NM. Old Range Site descriptions based on 1983 MLRA maps and concepts
• 2003 MLRA map and concepts is compatible with surrounding states published ESD data.

Recommendations for correlation of ESD’s and TEUI data
Decide on a consistent scale to correlate.Agree upon site selection criteria for ecological sites (stability, diversity, function).Uniformly embrace a vegetation taxonomic system (e.g., NVCS).Strive for a data-driven state and transition model.Develop additional crosswalks between systems.
