How old must a tree be to be considered old?

It's not just tree age:

That long because old growth forests are characterized by a lot of fallen trees that create habitat and openings for different types trees to grow. So these are much older than the forests we see around most of Vermont that have trees that are mostly similar size and only a few downed ones.

Life is resilient so wouldn't that same ecosystem rehabilitate around 50 year old forest? I own land which was cleared for farming in the early 1800's which fell fallow so the forest encroached and there's living fossil neolectica irregularis mushrooms growing from the soil. All sorts of diversity.

It depends on the tree species but generally around 150-250 years or older.
>Hardwood forests of the eastern United States can develop old-growth characteristics in 150–500 years. In British Columbia, Canada, old growth is defined as 120 to 140 years of age in the interior of the province where fire is a frequent and natural occurrence. In British Columbia's coastal rainforests, old growth is defined as trees more than 250 years, with some trees reaching more than 1,000 years of age.[9] In Australia, eucalypt trees rarely exceed 350 years of age due to frequent fire disturbance.[10]
