The passion for trees exhibited by the presenters was infectious (the good kind) and has inspired me to take more notice and care of such a precious resource, our urban forest.



“I had a really good experience and learnt much more than I expected! The classes were interesting and engaging and informative. After the course I paid much more attention to the trees I encountered and their natural and human-made environment (including the other plants and animals who live among the trees.)” 



“I'm pretty sure I've been a "tree "tender" since grade 2, when I started the environmental club and watched The Lorax every night. The fact that LEAF offers accessible, high quality training to enthusiastic tree lovers living in the city makes what seems like an uphill battle all the more worthwhile in a team of passionate plant people all helping to make it happen!”



“I really appreciate how much I will take away from this course. Now that I have a better understanding of what trees need I am already starting to see things in my community that can be easily fixed.”


“This class opened up the world of trees into my life: the biology of trees, the science of soil, the types of trees there are and how to identify them, how native trees are so much better than imported trees, and how our trees can help us survive climate change, and way more. Now I want to learn more, because as a citizen arborist maybe I can do my bit to help our community survive the upcoming crisis of climate change.”
