NatureContemporaryNorth America (Mojave Desert, southwestern USA)low confidence

The Mojave Desert subpopulation occupies only the most well-studied 30% of the larger former range of the desert tortoise, yet this portion experienced the greatest human impacts and the largest documented past population losses.

Notes on verification

Verbatim match to USGS/IUCN Red List assessment (Berry et al. 2021), with corroboration from taxonomic literature (Murphy et al. 2011) on the 30% range figure and independent population decline data (Berry et al. 2020, USFWS) supporting disproportionate human impact.
