First of all are you shure it was wildlife services and not a priveate contractor? The agreement that is signed with W, S. Is not a binding contract it simply states the species we are allowed to take and the methods we are allowed to use to take them , the agreement can be cancelled at any time and is good for 5 yrs . All aireal opperations consist of a ground crew that will remove carcases from fields roads andtanks and dispatch wounded a nimals . The reason they are left is they must be inspected to give away to puplic and they would be liable if some one got sick. So 40 hogs half m half fm 20 sows haveing about 12 to 10 in a litter with a motality rate of 2 percent makes how many

Thats why the heli is such a valuible tool in controling wild boar populations.
