The Mother Tree Project builds on three decades of research by Dr. Simard and her lab, which has produced numerous journal articles, book chapters and conference presentations on tree communication.

Cover of 1997 Nature featuring Wood-Wide Web article

Cover of the August 1997 issue of Nature, where the term “wood-wide web” was coined in reference to the paper “Net transfer of carbon between ectomycorrhizal tree species in the field” by Simard et al.
