Karen Kabnick

After retiring in 2020, Karen Kabnick wanted to do everything she could to help mitigate the damages of climate change and habitat destruction. Karen met Andrew at a volunteer event and was thrilled to learn he, too, loved to rescue and nurture seedlings of native trees. They shared that hobby. She learned all about the countless benefits of trees and how to plant them from Andrew, friends, courses and reading, and wanted to use her new-found knowledge to help Andrew with Colonial Canopy Trees to restore our local canopy and re-establish wildlife habitats.
