There's a mystery behind some of western Montana's furriest foreign invaders.
The Eastern Fox Squirrel was introduced into Montana in the early 1960's. The new species found refuge in the hard-wood trees which were introduced to the state by the early settlers of Montana towns. Shortly thereafter, the native species of squirrel had been chased off and the Eastern Fox Squirrel had established it's place as the dominant squirrel species in western Montana.
UM News reporter Drew Trafton and photographer Jaime Berg bring us the story.
