Dynamic spatial conservation boundaries and internal zoning of Madagascar from 2000 to 2025

This dataset extends the World Database on Protected Areas (WDPA) with time-bounded states documenting boundary modifications, status reclassifications, governance changes, temporary protections, and internal zoning. It covers 123 terrestrial protected areas in Madagascar from 2000 to 2025. Data were compiled by integrating historical archive snapshots, national system datasets, legal texts from the national legislative database, and expert literature. All amendments are stored in a version-controlled YAML registry and consolidated through deterministic rules. The dataset is provided for spatio-temporal analyses of conservation histories.
