LIFE (Land-cover change Impacts on Future Extinctions; Eyres et al, 2025) scores land layers for 30,875 terrestrial vertebrates at 1 arc-minute resolution. These maps provide estimates of the expected changes in the number of extinctions (both increases and decreases) caused by (1) converting remaining natural vegetation to agriculture, and (2) restoring farmland to natural habitat.
The resulting maps can be used at scales from 0.5-1000 km2, and offer opportunities to estimate the impact on extinctions of diverse actions that affect land cover, from individual dietary choices through to global protected area development.
The LIFE conversion to arable layer shows the change in number of extinctions that would occur if current natural habitat was converted to arable land and largely results in increased extinctions (i.e. largely positive values). The LIFE reversion layer shows the change in extinctions that result from restoring agricultural lands (arable and pasture) back to potential natural habitats. This predominantly results in a decrease in extinction (i.e. largely negative values). All values in the layers are presented as extinction/km2 of land that has changed in a pixel.

This directory contains two Zarr v3 stores. versions.json lists both and keeps the published v1.01 release as latest.
Both stores cover the same 21,600 × 10,800 base grid and have overview factors 2, 4, 8 and 16. Their root and array attributes describe the levels, values, units, scenarios, provenance and terms. The overlapping scenario values differ between versions.
The base layers of both stores were compared with every source GeoTIFF cell, and GDAL read checks passed. Logs of the conversions and checks are in this directory.
The data carry IBAT terms of reference: non-commercial use only and no redistribution in the original form without prior written permission. The full terms are in each store's terms_of_reference attribute.
