Most recently, the radical animal rights organization attempted to push back against an urban hunt in Ann Arbor, Michigan, by proposing the non-lethal fertility control method. The City Administration there had recommended the hiring of sharpshooters to conduct annual culls of deer in the urban areas starting in 2016. This plan would also include a recommended ban on feeding deer and greater study of herd population size and movement. All of these are logical ideas meant to curtail a booming deer population in the city, and eliminate the well-known threats deer overpopulation causes.
These methods were recommended after a Cornell University study found that even with a 90% medication rate using HSUS-preferred sterilization methods; you can only stabilize the deer population. Additionally, the study pointed out that in suburban landscapes, like Ann Arbor, over 95% of female deer must be able to be surgically sterilized or the community should not even consider a sterilization program for population control. The cost of such a method would exceed $1,200 per deer.
