How do trees talk to one another?

Dr. Suzanne Simard in the TED talk https://www.youtube.com/watch?time_continue=4&v=Un2yBgIAxYs  provides an excellent description of the research work she and her colleagues have done regarding how trees exchange nutrients and awareness of up coming disease attacks through their roots.

Scientific research is intended to inform forest management policy and practices.  Foresters are confronted with many challenges planning and implementing actions to achieve long-term forest stewardship.  The process involves balancing environmental, economic, social and cultural values.  The challenge in the case of the research provided by Dr. Simard should be how to include this knowledge as a serious part of the input into the forester’s decision-making but not necessarily the only component in the decision.
