A single tree can be an entire ecosystem in itself from all the fungi, lichens, insects, mammals, birds, etc. etc. A loss of tree species means a loss of others

A single tree can be an entire ecosystem in itself from all the fungi, lichens, insects, mammals, birds, etc. etc. A loss of tree species means a loss of others too. A lot of migrants birds and animals depend on seasonal fruits and nuts as they move south so the effects of species loss can be very far ranging indeed. While the idea that planting more trees to ameliorate climate change is a good one there is a risk that simple, ignorant, solutions such as planting fast growing eucalyptus or pine species could be seen as the fast path to success. Instead focussing on native species, which are slow growing in comparison, would actually solve the much greater problem that comes with climate change - habitat degradation and generate ecosystems that are generally most robust and able to withstand stresses better.
