What Does Short-Lived Mean?
Of course I have a general idea of what this means but comparatively speaking I'm having trouble with the concept.
I believe I have identified one of my backyard inhabitants as a Silver Maple which is said to have rapid growth but to be short-lived at up to 130-150 years. I also have baby Mimosas in the house (for house plants only I assure you) and they are said to be short lived at 15-30 years.
I guess as a human, whose life-span is short compared to other species, 130-150 years would seem like quite a long time but moreover the difference between 15 and 130 years is what has me a little confused.
How old does a tree have to be able to get before it is no longer considered short lived?
