Yes, 'nature' is changing. Its forest is getting older.
Do you think the 4 successions of growth in the forest have anything to do with different animals so called 'expanding'? I am not asking sarcastically, but asking genuinely. Do you think your personal trapline animals have changed in the time you have had it?
Each different stage of growth has certain plants and animal species. In Alberta, in certain areas the forests are getting older. The plants and animals will change according to the maturity of the forest.
(Example: In the buffalo days of Alberta, where there were treeless plains, there are now mature bluffs of forest.)
As far as fisher expanding, back in the late 1990's there were 8 fisher released from a research location a few miles east of Edmonton. These fisher were tracked and some did move west along the North Sask. river and north. So a program like this might explain some new animals 'expanding' too. There may have been more animals released in the past year or two.
