NCGS Observer Roles
The capacity in which an observer acted. The single mechanism by which self-reported evidence is graded; methodologies demand a minimum role, never a separate shape (ADR-0004).
Fieldworker
The professional observer role: trained and supervised by the implementing partner.
Office analyst
Implementing-partner staff judging a site from the office, from maps, imagery or a phone call, never on site. Records only what can be judged that way: a site’s cover or point (#130).
Owner
An owner reporting on trees on their own property.
Reviewer
A reviewer making an observation in the course of validation or verification.
Steward
A steward reporting on trees in their care on someone else’s property.
Supervisor
An experienced implementing-partner staff member who supervises fieldworkers and may override a derived determination.
