New GFW Biodiversity maps help prioritize areas for conservation

Two new global datasets released on Global Forest Watch (GFW) enable us to say more about where forest biodiversity is located and how it is impacted by human disturbance.

The new “biodiversity significance” layer on GFW shows a visual representation of how important each pixel on the map is for conserving biodiversity (or how devastating it would be to lose). The layer uses species range data on birds, mammals, amphibians and conifers from the International Union for Conservation of Nature’s (IUCN) Red List, which has a 50-year history of assessing the conservation status of species. The GFW system calculates a “weight” for each pixel on the map based on both the number of overlapping species ranges and the proportion of the global range the pixel represents. This pixel weight therefore reflects the relative “significance” of each pixel for forest species globally.
