A practical checklist
- Identify the date and location of the earlier scouting note.
- Describe today’s coverage and whether it matches the original visit.
- State what changed, what persisted, and any detail that is still unknown.
June 21: “Revisited thin strip noted June 14 beside east lane. Same strip inspected; additional plants emerged since prior photo. Interior transects not revisited.” The comparison is limited to ground actually checked.
What to avoid
Do not edit the earlier observation to make it reflect today’s condition. That removes the evidence of how the situation changed over time.
