the total surface area (in m^2) used for cover estimates and for which a complete species list is provided. If subplots were used, this would be the total area of the subplots without interstitial space. RESERVED VALUE: -1 is used to indicate the complete list of species had no known boundaries.
This is the effort spent making the observations as estimated by the party that submitted the data (e.g., Very thorough, Average, Hurried description).
Quality of plot as determined by an automated filter system, including values such as (1) sufficient for determining type occurrence, (2) sufficient for inclusion in a classification revision, and (3) fully compliant with recommendations.
