You Are a Forester Charged with Increasing Productivity in a South

You are a forester charged with increasing productivity in a South American forest newly planted with pines from Oregon.You believe that the southern forest lacks the fungal diversity needed by the North American pines,and that this lack of fungi is affecting the pines' productivity,but you have no evidence to support your ideas.
Describe what you believe would be the best method of providing the appropriate fungi to the newly transplanted pines described in the previous question.Be sure to identify the source of the fungi and the stage of the life cycle during which you would transport them.Also explain how you would introduce the fungi to their new home.Explain why you believe your method would work,including relevant elements of fungal biology.
