Service Description: The Criterion 1: Biodiversity values v1.0 raster (250 m resolution) represents relative across terrestrial Australia, categorised into percentile-based thresholds that highlight areas of comparatively higher biodiversity importance. This layer was generated using a reproducible MCDA workflow implemented in Python and ArcGIS Pro. The workflow includes: Criterion 1: Integrated species diversity, endemism, threatened species and ecosystems, habitat connectivity, and ecosystem services. Inputs included national biodiversity datasets and ecological integrity indicators (e.g. Habitat Condition Assessment System (HCAS), National Connectivity Index (NCI) The final raster reflects areas where this criterion is met with scores out of 1000 and protected areas masked (assigned value of 4000). Higher scores (between 0 to 1000) equate to areas with higher biodiversity values.

Some of this data is derived from models with their own inherent uncertainty and levels of accuracy that should be considered when using this output. Outputs of this analysis should be considered alongside regional and/or local scale information, particularly when incorporated in the decision-making process. Species distribution models were used to derive multiple input datasets used in this analysis (e.g. species density and regional endemism). These datasets represent different information and use different methodology to derive results. This analysis uses the published Collaborative Australian Protected Areas Database 2024, which does not include areas protected since 30 June 2024. There are caveats associated with the datasets used in this analysis. Please refer to individual datasets for further information.
