Consequences of wolf culls in Alberta

[Catherine]

Alberta has been culling wolves since 2005. Hundreds have died. 
The purpose of the cull is to save the caribou who are in decline because of habitat loss.
They shoot the wolves from helicopters. The wolves have changed their behavior in response to the threat from the sky.
No one has studied the effects of this before. In the long term how does changed wolf behavior effect the caribou.

They kill the wolves because it makes it seem like they are doing something to help the caribou.
The caribou's real problem is habitat loss. Killing the wolves does not restore caribou habitat.
The wolves are not the ones who have damaged the habitat in the first place. Humans have done that.

Altered wolf behavior may or may not be harmful to the caribou. We just don't know.
Without restoring their habitat the caribou don't stand a chance anyhow. It is not the predators that are the problem.
Predators tend to strengthen a species be removing the weaker members of the species and leaving the resources to the stronger ones.

Before they go ahead with more culls they really need to study the effects of the culls they have done.
If the cull does not make things better for the caribou then they have lost their only justification for the killing.
