The Red List of Ecosystems or Ecosystem Threat Status and Protection Level are key ecosystem headline indicators calculated as part of the National Biodiversity Assessment (NBA) 2025. This vector map represents the current threat status and protection level of ecosystem types based on the 2025 NBA assessment. This map forms the foundation for many land-use decision processes, including conservation planning.

This layer was developed as part of the National Biodiversity Assessment 2025 and will be updated in future iterations of the assessment

The ecosystem threat status and protection levels reported in the National Biodiversity Assessment 2025 are based on the 2024 National Vegetation Map and the 1990, 2014, 2018, 2020, and 2022 land cover datasets. The IUCN Red List of Ecosystems methodology was first applied in the National Biodiversity Assessment 2018 terrestrial ecosystem assessments; therefore, the resulting ecosystem threat status and protection level indicators are not directly comparable across assessment periods.
