Infographic: A patchwork of lands fragments wildlife migration

For generations, elk and mule deer in the remote South San Juan Mountains along the Colorado-New Mexico border have migrated from summer’s alpine meadows down to the grassy lowlands where they spend their winters. Most of the higher portion of this major migration corridor lies on U.S. Forest Service lands, but the ungulates’ path also cuts directly through some of the largest privately owned properties in the region. If those parcels were sold and developed, their loss would cut off the seasonal wildlife flow.
