Quote:
Wolves have decimated the moose population in Minnesota. Recent official numbers prove that the wolf is largely responsible for the dramatic decline in the moose population of NE Minnesota.


This may be true and if so it would indicate that there were no significant predators for the moose and thus they were above the normal population for a balanced ecosystem.

Once the moose population declines to a certain level, the wolf population will also decline due to lack of food.

On the flip side, overpopulation of the moose will have a negative effect on their food source (in this case, specific plants). As their food source becomes scarce the moose population will begin to decline just as the wolves.
