DOMAIN: Hierarchical ecological unit code, referencing broad climatic zones or groups.
Domain code prefixed by "M" if unit includes mountains with altitudinal zonation. DOM_NAME: Domains are named according to principal climatic descriptive features. DIVISION: Hierarchical ecological unit code, referencing: Regional climatic types. Vegetational affinities. Soil order. (Subdivision of a Domain) DIV_NAME: Divisions are named for the main climatic regions they delineate. PROVINCE: Hierarchical ecological unit code, referencing: Dominant potential natural vegetation. Highlands or mountains where there is a complex vertical climate-vegetation-soil zonation. (Subdivision of a Division) PRO_NAME: Provinces are typically named using a binomial system consisting of a georaphic location and vegetative type or according to lower-elevation and upper-elevation (subnival) belts. SECTION: Hierarchical ecological unit code, referencing: Geomorphic province, geologic age, stratigraphy, lithology. Regional climatic data. Phases of soil orders, suborders, or great groups. Potential natural vegetation. Potential natural communities. (Subdivision of a Province) SEC_NAME: Section names generally describe the predominate physiographic feature upon which the ecological unit delineation is based. SUBSECTION: Hierarchical ecological unit code, referencing: Geomorphic process, geologic formation, surficial geology, and elevation. Phases of soil orders, suborders or great groups. Subregional climatic data. PNC--formation or series. (Subdivision of a Section)
SUB_NAME: Names of Subsections are usually derived from geologic features.
EUCODE: Code concatenation for fields domain through subsection. ACRES: Conversion from AREA (square meters) to acres.
CLIP: Flag for designating clipped features, i.e. polygons whose boundaries extend beyond the California border (including Lake Tahoe). A "1" indicates a clipped feature.
