Story summary
- U.S. Fish and Wildlife Service announced a male Mexican wolf crossed from New Mexico’s Bootheel into Chihuahua, Mexico, the first in decades.
- Conservationist Michael Robinson warned an 18- to 30-foot border wall could block crossings and worsen wolves’ inbreeding, cancers, and birth defects.
- Cyndi Tuell said U.S.–Mexico wolf interbreeding could improve the species’ critically low genetic diversity.
- Officials claim the wall is needed for security but added ground-level wildlife openings.
