The WT and Elk are way down in norther Idaho as well, mostly winter kill some wolf predation although the wolves seem to concentrate on the moose and elk more, the big bulls that stay in the deeper snow are SOL when the wolves find 'em. Not scientific, but the wolves and deep snow combined seem to be the perfect storm for high stress/low survival in the winter. The whitetails breed like rats but the elk recovery will be much slower, took 10 years last time.
