Below is a link to an interesting book about mother trees, based on
work done by Dr. Suzanne Simard, a professor with the University of British
Columbia Faculty of Forestry, shared by an Eden By the Bay reader.
Dr. Simard researches and lectures on mycorrhizae and mycorrhizal networks, related to tree migration and climate change. She and her students have
made discoveries about the networks of mycorrhizal fungal mycelium, which connect
tree roots and enable resource sharing in Douglas-fir (Pseudotsuga menziesii) forests in British Columbia.
The research asks the question “Do trees communicate?” Using isotopic
labeling, two of her students have mapped the interconnections of the plant
community through mycorrhizal networks. The research describes the role of “Mother Trees”, where an older tree
acts as a hub with other trees in the plant community through mycorrhizal networks.
Carbon, nitrogen, and water are transferred from healthy, old trees to seedlings
and other trees in the network, improving their chances for survival. Mycorrhizal
networks may help forests adapt to climate change, and help with forest succession after disturbances
such as fire, insect infestation, or logging.
