True. I was kidding with him, but it may be better to say that it has changed minimally instead of not at all. I guarantee a tree or trees have fallen from a storm or etc. Something has to have changed somewhere.
A tree or two falling is not enough change IMO. Now a tornado , wildfire would be a different story.
If your "habitat" consists of only mature hardwoods then 1) I feel sorry for you because your "habitat" sucks, 2) you can't tell me that a top didn't die somewhere allowing sunlight in or a blueberry bush finally grew too tall for deer to browse, therefore habitat change and 3) your habitat then consists of primarily acorns which DO change in quantity and species that are falling, hence habitat change. I would not consider "no change" in a case where your property is half a deers home range since habitat is changing on the neighbors. Mature hardwood is as close to no change as you could get just not there, again IMHO.
