The culprits? There are likely two: coyotes and mast. There's little doubt that a coyote population boom is taking place. It's nothing to hear 3 or 4 packs of dogs howling most any evening at sundown. While they don't likely take down too many adult deer, their impact on fawn recruitment is, to me, clear. This summer I watched a pair of does with two fawns each feeding in my food plots. Then I'd see them with one fawn each and finally by themselves.
