Does dismantlement of the Shelter and management of radioactive waste pose further environmental problems? The protective ......searchers were able to examine the effects of wolf exclusion on elk--wolves' preferred prey--on plants such as willow, which are favored by the ungulates, and on other species that depend on the willow habitat.
