Effectiveness of conservation lands in Mexico for safeguarding terrestrial endemic species from the human‐induced extinction crisis

open access: yesConservation Science and Practice, Volume 8, Issue 8, August 2026.
Across 1639 endemic Mexican species, we show that most species' ranges coincide with moderate to high human pressure, while existing conservation lands cover only a small fraction of their distributions. This spatial mismatch indicates that current conservation–land networks are insufficient to prevent future biodiversity loss. Substantial expansion of
