rambopacker I live just outside of Yellowstone & can tell you that the moose population has thaken a HUGE hit since the reintroduction of wolves. The head biologist incharge of the wolf reintroduction says, the Yellowstone ecosystem is at its maxium capacity for wolves. The wolf is also killing a ton of elk & deer. The wolf population is close to 670-wolves in the yellowstone ecosystem. When the biologist told us of reintroduction plans in 1994. They said the total population in the yellowstone ecosystem would top out at around 100-wolves. They were either lying or were just way off.
