Designations and boundary evidence

Daem Thkov conservation zones

The 25-ha and 64-ha areas are listed in Annex 4 of Prakas No. 364, PDF page 9: rows 1 and 2, map codes 1 and 13. They are supported historical zoning records. Their present relationship to national-park zoning remains unresolved.

Ream National Park

Ream was designated on 1 November 1993. Sub-decree No. 10 of 10 January 2022 renamed it Ream Sihanouk Marine National Park and set out 39,634 ha: 19,380 ha of land and 20,254 ha of water.

Sub-decrees Nos. 11 (2022), 241 and 242 (2023) subsequently address park land or management zones; they are separate from the 2014 atlas outline.

The map retains the ODC record last updated on 22 May 2014. It does not show the expanded 2022 marine boundary or a consolidation of later changes.

Botum Sakor National Park

Botum Sakor National Park was designated on 1 November 1993. Sub-decree No. 175 of 17 July 2023 adjusted its stated area from 171,250 to 143,895 hectares.

The National Park category is retained.

The atlas polygon is the ODC record last updated on 22 May 2014; it has not been replaced by the July 2023 boundary schedule.

Peam Krasop Wildlife Sanctuary

Peam Krasop Wildlife Sanctuary was designated on 1 November 1993. Sub-decree No. 164 of 17 July 2023 adjusted its stated area from 23,750 to 16,982 hectares.

Sub-decree No. 261 of 15 August 2023 separately concerns 15.39 ha of tourism-project land; that figure is not a replacement sanctuary total.

The atlas polygon is the ODC record last updated on 22 May 2014; it has not been replaced by the July 2023 boundary schedule. The 2023 schedule repeats point number 23, a source inconsistency requiring reconciliation before reconstruction.

Koh Rung Marine National Park

Sub-decree No. 14 of 8 February 2018 established Koh Rong Marine National Park: 52,498 ha, comprising 5,361 ha of land and 47,137 ha of sea. Article 6 repeals the 2016 national-park Sub-decree No. 188.

Sub-decree No. 48 of 27 February 2023 addresses 174.6438 ha of park land. Its effect on individual mapped parcels has not been reconstructed.

All 13 outer vertices match the 2018 decree’s coordinate table to within 0.01 m after transformation. The polygon has no internal exclusions, however, and measures about 57,483 ha; it is an outer reference outline, not the net 52,498-ha legal area or a current consolidated boundary.

Prek Kampong Smach MFMA

Prakas No. 504 of 26 December 2022 establishes 10,923 ha. Its annex includes a boundary map in WGS 84 / UTM zone 48N. The atlas has not reconstructed a current consolidated polygon.

Fisheries-zone source concordance

All 55 mapped zone areas have corresponding entries in the original schedules. The table preserves the decree’s stated area alongside the area calculated from the displayed polygon. A difference can reflect digitisation, rounding, a source-coordinate problem or other geometry discrepancies; it is not evidence of a legal change.

Areas calculated geodesically on WGS 84 from the displayed polygons. Seven differences exceed 10%. The original 7,011-ha Preaek Svay community-fishery entry is also present in Prakas 364 (row 45, map code 6, PDF page 16); its invalid source polygon remains withheld.

Koh Tang proposal

The partner-supplied Koh Tang MFMA outline remains labelled Proposed. No designation is inferred from the proposal, habitat polygons or this legal-source check.

Coverage and remaining boundary work

The check covers all 60 atlas boundary records: 55 fisheries zones, four protected-area outlines and one proposal. Original instruments and later changes were located through the cached source catalogue, ODC legal records and targeted public-source searches. This is a bounded source check, not an exhaustive legal register.

Historical zone coordinates still require full reconciliation, later parcel changes require spatial consolidation, and the Peam Krasop coordinate schedule contains a repeated point identifier. Current restrictions cannot be determined from an old outline alone.
