A
Would it surprisc you to lcarn that,like animals,trees communicate with cach other and
pass on their wealth to the next generation?
UBC Professor Simard explains how trees are much more complex than most of us ever
imagined.
Although Charles Darwin thought that trecs arc compcting for survival of the fittest,
Simard shows just how wrong he was.In fact,the opposite is true:trees survive through their
cooperation and support,passing around necessary nutrition"depending on who needs it".
Nitrogen (and carbon are shared through miles of underground fungi )networks,
making sure that all trees in the forest ecological system give and reccive just the right amount to
keep them all healthy.This hidden system works in a very similar way to the networks of
neurons (in our brains,and when one tree is destroyed,it affects all.
Simard talks about"mother trees,usually the largest and oldest plants on which all other
trees depend.She cxplains how dying trees pass on the wealth to the next gencration,
transporting important minerals to young trees so they may continue to grow.When humans cut
down"mother trees"with no awareness of these highly complex "tree societies"or the networks
on which they feed,we are reducing the chances of survival for the entire forest.
"We didn't take any notice of it,"Simard says sadly."Dying trees move nutrition into the young
trees before dying,but we never give them the chance.If we could put across the message to the
forestry industry,we could make a huge difference towards our environmenial protection efforts for the
future..”
