I don’t mean differing tree types, but trees in the same woodland, of the same species, can be in completely different stages of shedding- how come? Why do they not all loose their leaves around the same time?
In: Biology
Different trees have different triggers. Some react to changes in temperature. Others to light intensity or length of daylight. And all have their own internal clock. There is just the same variation in when trees bud, come into leaf, blossom and seed.
