Wonder if there's any residual left in the deer and what effect it has, if any, on someone that might eat the deer.
Single-Treatment Procine Zona Pellucida Immunocontraception Associated with Reduction of a Population of White-Tailed Deer ...AT Rutberg, RE Naugle, F Verret - Journal of Zoo and Wildlife Medicine, 2013... Previous reports have demonstrated gradual reductions of white-tailed deer (Odocoileus virginianus) populations through immunocontraception, with stabilization occurring after 2–4 yr of treatment, and subsequent reductions of 6–10% annually. These studies employed porcine zona pellucida (PZP) vaccines that required two initial treatments and annual retreatments. From 2005 to 2010, 258 adult and yearling female deer on Fripp Island, South Carolina, were treated with one of several PZP preparations designed to produce 2+ yr of effective contraception with a single treatment... From 2005 to 2011, deer density on Fripp Island declined by 50%, from 72 deer/km2 to 36 deer/km2, an average annual reduction of 11%. In contrast, population density on the Hunting Island control site fluctuated between 2005 and 2011, averaging 23 deer/km2 (range, 19–28 deer/km2)...http://www.deerfriendly.com/deer-population-control/deer-birth-control-contraception
Why not just add some weeks to hunting season? Decrease deer hunting license fees? Open up more area where deer hunting is permitted?
Just a guess, but they must be talking about urban/suburban populations where they don't hunt. There are a number of areas here that are heavily populated and developed and in which significant deer populations reside.
And significant hunters do not.
Not so much a problem here, but the houses are way too close together to hunt in. You'd take out the neighbor's dog or kid if you did.
Nah... Many communities are open to bow and shotgun. here, close into town, there are woodlots where the deer live, and areas down along creeks and rivers where they go for water... Those areas are good for hunting with low powered means.
