A closed reef is a governance decision, not an empty map
Community rules for reefs and lagoons are working systems with ecological, cultural and livelihood consequences.
A marine area can be closed or managed by season without looking different in a satellite image. Name the authority, rule, period and evidence.
Authority
The map is not the whole institution
A boundary does not replace the people who explain access, harvest and enforcement. Community-managed areas often rely on obligations a dashboard cannot show.

Trade-offs
Conservation can have a cost
A closure may protect fish while shifting effort, income or food pressure onto another household. The policy story is incomplete without who absorbs that cost.
Reference: The Pacific Community (SPC)
Evidence
Pair scientific monitoring with local observation
Give the date, method and collector for each dataset. Do not generalise one island rule to the region.

Questions visitors ask
Who can close a reef?
It depends on the local legal and customary system. Start with the authority named in the current local rule.
Does closure mean no one can enter?
Not necessarily. Fishing, ceremony, research and emergency access may have separate rules.
