A completed project product
Local ecosystem poster — completed fictional case: Keep the Stream Connected. Diagram description: stream water, bank vegetation, insects, small fish and fish-eating birds form interacting parts; the arrows in a food chain run from food to consumer. Threat: trampling damages banks and increases sediment. Response: stay on the public path, restore suitable native plants with expert approval and monitor from fixed safe points. Indicator: dated observations of bank cover and water appearance, with weather noted. Limitation: appearance alone does not measure chemical water quality. The poster is a worked example, not a claimed field survey.
