#Deer665's route shows the bigger picture of ungulate migrations in the American West: Animals move from desert winter ranges to lush summer ranges, maximizing the extreme contrast of the seasons to their advantage. These migrations support abundant herds and intact ecosystems. #Deer #Science

In South Park of #JacksonHole, #Deer665 bounded across busy US 26/191 and passed ranch lands, a golf course, and conservation easements before swimming the Snake River. Then she climbed over the 8,400 crest of #TetonPass to reach summer range.

By June 2nd, Deer 665 had climbed to a spot 1.5 miles north of US 191 where it enters the east side of Hoback River Canyon. This is close to where Deer 665 was born in June 2021, a story we are excited to share in the coming weeks. (Image of Hoback Basin pronghorn from May 2018)

#Deer665 has migrated a long way to reach these slopes of wildflowers, aspen and pine that offer food and security. Raspberry Ridge is one of #Deer 665’s favorite stopovers from previous years. She spent five days here in May 2024, and two weeks in June 2023. (Clip from 2018.)

This effort is a great example of migration data leading to targeted, voluntary conservation.

The Luke Lynch wildlife refuge was named in memory of the #Wyoming director of @theconservationfund who raised more than $2M to purchase and restore the land & donate it to WY Game and Fish Dept.

The map shows her swimming across Fremont Lake bottleneck outside of Pinedale on May 20, though our GPS didn’t pick up the exact crossing location.

From there #Deer 665 moved through the Luke Lynch Wildlife Habitat Management Area.
