A small carnivore known as F003, a fisher in New Hampshire, made an 80-mile journey from Durham to Lincoln, setting the longest documented dispersal journey for a fisher. The journey was tracked via a GPS collar and revealed that F003 left her mother when she was just a year old and left on her own, leading to her long journey. It also revealed that modern roads and habitat patches pose a dangerous route for this predator. F003's journey also taught biologists and researchers more about how fishers migrate and how to better protect this species moving forward. The author also discusses the implications of this migration for both her species and other mammals that venture similar ways.
