100 Words on Wildlife Connectivity

Our new blog series featuring conservation concepts and commentary in 100 words. Today: the importance of connectivity.

Imagine grizzly bears: roaming two mountain ranges, national forests both. In between: a valley, with farms, ranches, patches of trees.

The grizzly uses that valley to move from one national forest to the other, giving them room to migrate, breed, feed, take cover.

It’s the habitat equivalent of an Oreo cookie. Remove the gooey white center from the Oreo, and you have most of the cookie remaining. But you don’t have an Oreo.

Remove the valley’s trees and open space, and you have most of the grizzly’s habitat remaining.

But you no longer have a viable home for grizzlies.
