A University of Toronto student as published a thesis on the use of fertility control to manage wolf populations. She studied 17 surgically sterilized wolves in seven wolf packs and found that the wolves "maintained existing pair bonds, defended their original territories, and exhibited denning behavior."

The student, Christine Elizabeth Spence, modeled the use of various techniques to control wolves and found that fertility control can help augment moose and caribou population increases, "but lethal control is required to initiate the recovery of a critically small caribou herd."
