A group of University of Toronto forestry students collected acorns from a giant White Oak tree at Queen’s Park on Wednesday as part of an effort to preserve the diversity of Toronto’s native trees. Eric Davies, a forest ecologist at the University of Toronto, led a group of undergraduate students in the university’s foresters club as they gathered about six litres of acorns from a tree in Queen’s Park North, one of four remaining large White Oaks in the park. White Oaks, a common deciduous tree species in North America, are the largest and oldest trees in the green spaces outside the Ontario Legislature. …Davies said timing is key, as White Oaks produce acorns about once every five to 10 years — this year being one of them. …Davies said the students will donate most of the acorns to the City of Toronto’s tree seed diversity program in the next two weeks. Some of the acorns will be kept at U of T to be grown there, he added.
