About the evidence

Clearer records and supporting evidence

Each record opens an Overview, Measurements and Sources view. Common names are paired with scientific identifications where a reference was verified; both are searchable. Missing common names remain explicit. The one verified Khmer name is romanized and labelled as such. Original taxonomy and source fields remain in downloads.

Availability badges distinguish reviewed findings, saved PDFs and extracted tables. Observation records do not necessarily have a research paper. Twenty-eight source summaries are reviewed and fifteen public PDFs are saved. Carbon profiles, seasonal larvae counts, spawning dates and national mangrove history are visualised alongside source tables.

Coverage and interpretation

The collection catalogues 87 sources; 38 currently contribute 9,513 records through 44 subject selectors. Records include polygon fragments, annual images, environmental grid cells, sampling positions and approximate study areas. They are not counts of independent studies or animals.

All 41 GMW v4.1.12 annual mangrove classifications (1985–2025) are available, with a native 30 m clipped GeoTIFF download. Display images use maximum-presence resampling at 60 projected metres in Web Mercator; small patches may appear enlarged. National accuracy-corrected estimates are separate from raw mapped pixel area. Earlier years can include infilled observations.

Clark wetland and aquaculture maps cover 1999, 2014, 2018, 2020 and 2022. Compare years opens synchronized maps of the same product. Apparent differences are not automatically ecological change, and the Clark 2018 archive/page version discrepancy remains flagged.

Environmental additions include a NOAA heat-stress snapshot dated 27 September 2026, fifty Copernicus monthly salinity/current samples for May 2026, and published 2023 Kep field measurements. The satellite and model snapshots are dated estimates, not continuously refreshed observations. GEBCO supplies seabed-depth context.

Positions, effort and repeated research

Squares identify field sampling positions; diamonds identify DNA sampling stations; hollow dashed markers are approximate study areas. Habitat image footprints are not habitat boundaries. Dashed historical boundaries do not establish current legal status. Region-wide environmental products include neighbouring waters.

Nearby research is a discovery aid, not proof of repeat sampling. Carbon depths and biomass cores belong to one campaign. Each reef in the 91-site dataset was visited once. The paired Kep papers share the 2023 campaign, as do the mangrove fish report and goblinfish paper. Twenty net-sampling positions represent ten stations, not twenty independent campaigns.

Fieldwork dates, publication dates and product dates remain distinct. Missing values and non-detections are retained as such. Empty map areas indicate missing displayed evidence, not absence of habitat or wildlife.

Unresolved source data

Original habitat GIS, malformed 2019–2020 larvae coordinates, exact offshore station tables, precise port sampling coordinates, PML processed grids and raw logger time series remain incomplete. Carbon coordinate conflicts and the Clark 2018 version discrepancy require provider clarification. These gaps are documented rather than filled with invented geometry or measurements.

Attribution and reuse

MRPO compiled the presentation. Original evidence remains attributed to its authors and providers and retains its terms. Watermarks identify the compilation, but cannot prevent screenshots or removal. Exports preserve source credit. This is not a navigation chart or an authoritative current zoning map.
