Good question.  I live out on Stampede road and it does seem like there are more moose and more hunters out here the last few years.  NPS does aerial counts every so many years but I haven't heard how recently they might have counted moose.  Or what ADF&G has to say about it.  Seems like less wolves and bears would mean higher moose calf survival rates but I guess there is a lot more to it than just predator numbers.
