Interesting collection of trees. I don't believe these are even warm climate trees. Mimosa is our worst tree here.
ReplyDeleteHumanity has celebrated the invaders when they succeed; to the victor go the spoils. Why not in plants? In general, humans alter the landscape which creates the niches that these invasive plants are now filling. They are, perhaps , righting our wrongs by maintaining (?!) plant cover. How is it that with our thousand years experience we still can't see the forest for the trees ?
ReplyDeleteI'm very surprised that the Sycamore
ReplyDelete(Acer pseudoplatanus)is not on the list. In Tasmania, Australia it is one of our most invasive trees.
