Every forest has its share of mature, majestic trees. Forest ecologist Suzanne Simard, A______________, calls these "mother trees". She and her colleagues have recently found that they are crucial to the well-being of the entire forest community. They are the hubs of communication, protection and sentience, they support their own offspring and B______________. This has crucial implications for the way we manage forests, which is why, in 2016, Simard launched The Mother Tree Project to C______________.

"It's the biggest project I've ever done," says Simard. It involves 24 Douglas fir forests located in nine climate regions in British Columbia. Each forest is logged using five different harvesting treatments, ranging from felling all the trees in an area to keeping large patches of trees with mother trees present. The team monitors and measures D______________ by collecting information before and after logging about things like carbon storage, biodiversity and productivity.

Research is ongoing, but there have already been some compelling results. "We've found that the more mother trees we leave, E______________," says Simard. Her team also has good evidence F______________, especially when conditions get tough, such as when there is a frost or a particularly hot, dry day. By comparing results in different climate regions, the researchers aim to identify more sustainable ways to manage forests in the face of climate change.
