Guys, have you got a solution for this? The dilemma of killing one type of Owl to save another

This post is an afterthought of reading an article by Elizabeth Cook in Sanfrancisco.cbslocal

Killing one species to save other sounds weird, but this is exactly what is happening in Northern California.  U.S. Fish and Wildlife Service is trying to protect the Spotted Owl from the marauding Barred Owl, by shooting them.   Barred Owls are taking over the nesting territory of the native spotted owl, a threatened species. Spotted owl numbers have dropped by 80-percent in the last 20 years.  The plan is to kill 3,600 barred owls over the next four years. The think tanks of USFWS think that this is the only viable solution to the vexed problem.

So, guys, mull over this. If you have any out of the box ideas, that will work, please pass it on to USFWS.
