This layer shows the Biodiversity Intactness Index (BII), the estimated proportion of the original biodiversity still remaining in each pixel. Values range from 0 (completely altered ecosystem) to 1 (intact community). The data comes from the GEE Community Catalog BII product (Impact Observatory / Vizzuality, built on the PREDICTS database) at about 100 m resolution, as a mean composite over 2017-2020. Read greener areas as more intact ecosystems and red areas as heavily degraded ones.
The Biodiversity Intactness Index (BII) estimates how much of a location's original biodiversity remains relative to an undisturbed baseline community. Each pixel carries a value between 0 (completely altered) and 1 (intact), so it captures the cumulative impact of land use and human pressure on local ecological communities.

The BII image collection (projects/ebx-data/assets/earthblox/IO/BIOINTACT, band BioIntactness) is reduced to its mean composite over 2017-2020, clipped to the area of interest and resampled to a 100 m grid in Web Mercator. Per-polygon minimum, maximum and mean intactness are then computed, and the raster is rendered with a red-to-green gradient from low to high intactness.
