Guam Protected and Conserved Areas: WDPA and WD-OECM Geospatial Data

This geospatial dataset maps marine and terrestrial protected areas in Guam, integrating the World Database on Protected Areas (WDPA) and Other Effective Area-based Conservation Measures (WD-OECM). Managed by the UNEP-WCMC and IUCN, the data serves as the official record for tracking Guam's progress toward the Kunming-Montreal Global Biodiversity Framework and was last updated in March 2026.

Use Cases

• Identifying biodiversity risks within project boundaries for commercial environmental impact assessments
• Spatial analysis of marine reserve distribution versus terrestrial protected zones

Strengths

• Joint product of the UN Environment Programme and the IUCN
• Includes both WDPA and WD-OECM conservation categories
• Available in four GIS-ready formats: GEOJSON, GEOPACKAGE, CSV, and GEOSERVICE
