There are many examples of natural regeneration happening here now with strangler figs establishing themselves on short-lived wattles and stumps of removed camphor laurels. It has taken 20 years of observation to have the satisfaction of seeing Mother Nature reclaiming degraded land. My input being the hand removal of misplaced plants that are inhibiting indigenous trees emerging.
What we call an exotic plant here in Australia came in after we did in 1788. I think we should pay them less attention, cease our use of herbicides in trying to control them and learn how to extend our native habitat by paying real attention to what is happening on the ground. Yesterday I read that the vanilla bean ( Australia imports most of our vanilla ) grows very well on the Indian Coral tree which one of our local landcare coordinators wants to get rid of. I counted 4 species of birds sipping the nectar of the coral tree flower during the winter months. Surely as climate change speeds up all our birds will need all the nectar than can get. The coral tree is here, so are we, mainly European who too could be grateful for what food species grow to sustain us as climate variability changes what we now take for granted.
Reading yesterday of the fungi that is destroying the UK’s beautiful Ash trees. I wonder if anyones thinking will include that the massive scale of the chemical inputs of industrial farming could be contributing to the declining health of the soil therefore lowering resistance to these air-borne fungi spores. Like humans over use of antibiotic, which has seen super bugs emerge, the same is happening with the use of herbicides. American conventional farmers ( herbicide, artificial fertiliser users, gm seed planters ) are now seeing super weeds emerge to which they have no effective herbicide to use. Many are now feeling duped by the excessive claims of their own Agriculture departments.
