eli5 If you cut down a perfectly healthy tree, at what point would the tree be considered “dead”?

Question

I would assume the fallen tree would have enough nutrients to sustain itself for a while and would eventually start dying. Most living things are dying until they’re dead but what exactly is the threshold from dying to dead for a suddenly severed tree?

Healthy? The root system is still going strong so after a period (1-3 human seasons) of shock and dormancy, new shoots will come up. This could repeat for generations.
