Ungulate prey availability to inform Mexican wolf recovery within its historical range

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We estimated the potential ecological carrying capacity for the Mexican wolf based exclusively on ungulate prey biomass estimated from camera trap surveys. In the United States, the potential density estimate is high (21.4–52.7 wolves/1,000 km2) owing to the presence and relatively high densities of elk, mule deer, and white‐tailed deer.
