CAMBODIA MARINE EVIDENCE

Data availability by source

Source coverage, available measurements and geographic detail. A general-area pin makes a report discoverable geographically; it does not mean its raw data or boundaries are fully extracted.

KH01

FiA: Seagrass and Coral Reef distribution and monitoring in Cambodia

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Survey dates vary between components. These historical maps may not represent present-day habitat extent.

KH02

ODC marine fisheries management area

Mapped records available

55 mapped records · 0 general-area locators

About this evidence: Original 2016 and 2018 decrees support the reported zone areas. The map shows 55 historical ODC digitisations; one invalid source polygon is withheld. Later national-park designation does not certify each old fisheries subzone as current.

KH03

ODC natural protected areas

Mapped records available

4 mapped records · 0 general-area locators

About this evidence: Original designations and later 2022–2023 instruments are documented. The displayed ODC polygons are older versions; newer legal area figures are labelled by decree date and are not measurements of these outlines.

KH04

ODC fisheries resource management

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: The collection includes inland fisheries. Catalogue update dates are separate from field observation dates.

KH05

Through murky waters: Cambodian reef communities

Mapped records available

91 mapped records · 0 general-area locators

About this evidence: Each of the 91 sites was surveyed once; two sites share coordinates. This is a comparison between sites, not repeat monitoring through time.

KH06

Strengthening a blue economy after habitat loss

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Surveys used a 250-metre sampling grid across 62,146 hectares. Original station coordinates and habitat GIS files are not available in the atlas.

KH07

Diversity, abundance and distribution of seagrasses in three community fisheries

General study area shown

GL01

Global Mangrove Watch version 3

Mapped records available

GL02

Allen Coral Atlas

Spatial product; acquire and validate regional extract

0 mapped records · 0 general-area locators

About this evidence: Depth and cloudy water limit satellite coverage. A coral/algae classification does not measure living coral cover or reef health.

GL03

OBIS Cambodia

Mapped records available

1032 mapped records · 0 general-area locators

About this evidence: Locations and identifications come from the contributing archives. Quality flags are retained; 276 records fall outside the map area or lack coordinates.

GL04

GBIF occurrence API

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Records may overlap with OBIS and include inland species. Offshore records are not always assigned a country code.

GL05

Global Fishing Watch apparent fishing effort

Spatial product; acquire and validate regional extract

0 mapped records · 0 general-area locators

About this evidence: Estimates use vessel tracking and models. Many small boats are not tracked, so mapped activity does not represent all fishing.

GL06

NOAA Coral Reef Watch

Mapped records available

1486 mapped records · 0 general-area locators

About this evidence: The atlas shows a satellite snapshot dated 27 September 2026. Heat exposure indicates bleaching risk, not observed bleaching.

GL07

GEBCO bathymetry

Mapped records available

1 mapped records · 0 general-area locators

About this evidence: Depth estimates use a 15 arc-second grid with varying source quality. They are not detailed nearshore survey measurements.

GL08

Protected Planet protected and conserved areas

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Database entries describe protected areas. Current legal boundaries depend on the relevant Cambodian designation and amendments.

KH09

SEAFDEC/UNEP-GEF Fisheries Refugia Cambodia activities

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Local reports describe fisheries refugia. A consistent series of measurements and downloadable boundary files has not been established.

KH10

Cambodian coastal fish eDNA study

Mapped records available

27 mapped records · 0 general-area locators

About this evidence: DNA sequences indicate detection, not numbers of fish. Genetic groups and reference trait lists are not necessarily confirmed species observations.

KH11

Pavona coral spawning in the Gulf of Thailand

General study area shown

0 mapped records · 2 general-area locators

About this evidence: Nineteen Cambodian supplement rows are available at two approximate island locations. Exact observation coordinates are not supplied; repeat visits may include the same colonies.

GL09

Copernicus Sentinel data

Research programme or source collections

0 mapped records · 0 general-area locators

About this evidence: Clouds, tides, depth and cloudy water affect satellite interpretation. Imagery requires a validated habitat classification before it can show habitat extent.

GL10

Marine Regions maritime boundaries

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: Reference maritime boundaries may include disputed areas. They are not a determination of sovereignty or legal jurisdiction.

KH14

Seagrass fisheries and poverty: multi-country household data and code

Source held; detailed mapping incomplete

0 mapped records · 0 general-area locators

About this evidence: The survey covers sampled locations rather than the whole country. The repository title differs from the paper title, but the publisher links the dataset.

KH15

NASA ORNL DAAC: Mangrove Extent Baseline from Landsat MSS, 1972-1977

Spatial product; acquire and validate regional extract

0 mapped records · 0 general-area locators

KH16

Clark University: Cambodia aquaculture and coastal habitat land-cover maps

Mapped records available

507 mapped records · 0 general-area locators

About this evidence: Five map years are available. The provider labels its 2018 map v5, while the downloaded archive contains v4; the atlas identifies the file version used.

Mapped records available

20 mapped records · 1 general-area locators

About this evidence: The atlas includes 20 net-sampling locations and a 74-taxon checklist. Counts for each species at each station are not supplied. The goblinfish paper uses the same campaign.

KH21

Duffy et al.: marine turtle population status and conservation in Cambodia

General study area shown

0 mapped records · 1 general-area locators

About this evidence: The research combines surveys, interviews and historical reports. Earlier nesting records do not confirm that beaches remain active today.

KH22

National Institute of Statistics: Cambodia Agriculture Survey fisheries and aquaculture

Source identified; document or spatial review pending

0 mapped records · 0 general-area locators

About this evidence: The survey includes inland activities. Province statistics depend on sampling weights and sector definitions; these are not vessel tracks or catch locations.

GL11

UNEP-WCMC Global Distribution of Seagrasses v7.1

Source held; detailed mapping incomplete

0 mapped records · 0 general-area locators

About this evidence: The regional query returned eight locations and no habitat polygons, including records in neighbouring waters. This reflects available records rather than habitat absence.

GL12

Global Distribution of Tidal Flat Ecosystems

Spatial product; acquire and validate regional extract

0 mapped records · 0 general-area locators
