Turn litter into actionable data, not just a before-and-after photo

The smallest useful dataset

For a cleanup report to become useful beyond one afternoon, record the location, date, approximate effort, and the main waste categories. A photo adds human context; a consistent category list adds comparability.

NOAA's Marine Debris Monitoring and Assessment Project is a good model because it standardizes shoreline observations. Garbamons can apply the same principle at a neighborhood scale without pretending that a community report is a scientific survey.

A simple field checklist

• Pin the exact place and note whether it is a beach, river edge, park, trail, or urban space.
• Record the date, duration, number of participants, and whether the site was revisited.
• Use broad waste categories first: plastic, fishing gear, glass, metal, cigarette waste, and mixed litter.
• Add an honest note about weather, access, hazards, and anything that needs a specialist response.

The action loop

A good record creates the next question: is the same litter returning, is the site safe to visit, or would a community event help? That is where a cleanup pin can connect to an Event, an update, or a later impact story.
