Figure 37.— Rocks and a dead tree that provide perches for hawks and owls on reclaimed area at the Rosebud mine in Mon- 

 tana. They were emplaced in 1973 by a front-end loader. The wheatgrasses and torbs are in their fifth growing season. 

 Providing habitats for predators has reduced the amount of damage by rodents to the new plantings. October 1978.
