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

open access: yesConservation Science and Practice, EarlyView.
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
