No. Moose need the northwoods. The swamps with the boreal forests. They also need it to be really cold with a good amount of snow in winter or the ticks get out of control and they die due to anemia. New England is suffering from that very thing right now. Hasn't been cold enough and the winter tick kill is taking it's toll. Moose have expanded all the way down to Connecticut in the past decade but if the warming trends continue even Massachusetts probably won't have a moose herd in ten more years.
Another thing that is killing moose is brainworm. They get it from whitetail deer and it takes a heavy toll on moose. A large percentage of deer have brainworm and it does them no harm. When there are too many deer (more than 2 psqm) and moose and deer feed on the same things the moose contract brainworm and it's always fatal to them. New England is having major brainworm issues right now as well. If we were entering into a mini ice age then PA could support moose. But if the warming trends continue a lot of the states that have moose will lose them.
I thought brainworm only affect elk and not moose?
Brainworm is the biggest challenge moose face today. The moose herd in Minnesota is largely gone due to brainworm and winter tick mortality. Interesting the Adirondacks in New York is a place where moose are on the verge of a boom. There are so many herds in decline in the US and Canada (even Alaska is in decline) that it's good to get some positive news on the moose front. Look for a moose season in New York in the next decade perhaps.
