Editing Biodiversity intactness index (section)

== Geographic / System Context ==
The biodiversity intactness index is not confined to a specific geographic region but is applicable across diverse ecosystems globally. It captures habitat condition by comparing current ecological community composition to a declared reference state that may vary depending on the spatial and taxonomic scope of the assessment. This flexibility allows the BII to be used in terrestrial, freshwater, and marine environments, adapting to regional biodiversity baselines and monitoring objectives. The index's design accommodates varying spatial scales, from local habitats to broader biogeographic regions, enabling comparative analyses and integration with other environmental signals.
