Conservation groups across the country are calling into question both the ethics and the effectiveness of a proposal to recover woodland caribou in Alberta.
The draft plan includes an experiment to fence a 100-square-kilometre area where caribou would be able to breed, and any predators that pose a threat to the enclosed herd would be killed.
The trial would study whether it is possible to restore caribou numbers in the absence of specific factors that either are responsible for caribou mortality or that compete with caribou for resources.
