A grizzly bear dubbed “Lingenpolter” by local biologists caught the attention of many in Montana and elsewhere last year. Using a GPS tracker, biologists watched as the young male bear repeatedly attempted and failed to cross Interstate 90. They followed Lingenpolter’s movements in an area between Missoula and Butte, watching as he traveled for miles alongside the interstate and tried to cross it an estimated 46 times from fall of 2020 to spring of 2021.
Lingenpolter’s story illustrates an issue facing many animals in Montana and beyond: highways, interstates and other major roadways fragment habitats, causing isolation as well as vehicle collisions that are often fatal.
Wildlife crossing infrastructure offers a solution.
