I would have thought otherwise, and officials at Cornell University in Ithaca, N.Y., certainly thought so and invested $1,200 for each operation. They reduced the number of births and the number of does but not the number of deer overall.
Perhaps a biologist could have saved Cornell thousands of dollars by pointing out that, if a doe does not get pregnant, it will go into heat each month. With tubal ligations, the does are in an almost perpetual state of heat. Bucks from all over the area quickly become aware of this and flock to the does So Cornell has a different gender mix of deer but about the same number. Cornell is now back to permitting archers and trappers to remove surplus deer. That has had the intended effect at no cost.
