This field survey documents 59 species of intertidal macroalgae across Pangandaran’s shoreline—spanning green (Chlorophyta), red (Rhodophyta), and brown (Ochrophyta) groups—with the highest cover in Madasari. Two non‑native Ulva species (U. lactuca and U. flexuosa) are particularly dominant. By linking species patterns to habitat type, temperature, nutrients, and tourism pressure, the study explains why some sites host rich, balanced communities while others are skewed toward a few opportunists.

The implications are immediate. Mapping substrate and wave exposure can identify refuges for sensitive species; tightening access and improving visitor behavior at busy sites can reduce trampling and eutrophication. The dataset also provides a baseline to detect climate‑driven shifts—such as warming‑tolerant taxa expanding during hotter seasons—and to guide restoration (e.g., seeding habitat‑forming algae at suitable reefs).

Macroalgae underpins coastal food webs, fisheries nurseries, and shoreline protection. Protecting this ‘hidden forest’ aligns with SDG 14 by sustaining marine biodiversity, complements SDG 15 through nature‑based solutions, and supports SDG 13 by tracking ecological responses to a warming ocean. The authors call for regular, low‑cost monitoring and citizen‑science identification to keep the biodiversity picture current and actionable for coastal planners.
