The remarkable changes have been recounted in the recently released book "Decade of the Wolf: Returning the Wild to Yellowstone," by Mr. Smith and Gary Ferguson. In 1995, 14 wolves from Canada were brought into the park by truck and sleigh, held in a cage for 10 weeks and released. Seventeen were added in 1996.10 years after wolves were introduced to Yellowstone, the park has 130 wolves dispersed across 13 packs.
