Canadian CLS environmental education program explores historical time lines. Can you take a trip back in time? Find out about electron beam energy, environmental education, and the Canadian Light Source TREE program. A webinar open toto everyone to learn about this programme, an introduction to the National Canada Wide TREE program where students from Grade 6 to 12 can meet with Dr Colin Laroque in the Mistik Askiwin Dendrochronology Lab (MAD Lab) to work with the Canadian Light Source (CLS) Synchrotron. What does the Canadian Light Source Synchrotron have to do with Trembling Aspens, and Climate Change? Tree ring patterns reveal lifestyles, climate history, and so much more! What kind of learning can be experienced peeking into the heart of trees? This program for National Forest Week is brought to you by the Friends of the Saskatoon Afforestation Areas an environmental non-profit charity that was created to preserve and restore the 326-acre Richard St. Barbe Baker Afforestation Area and the 148-acre George Genereux Urban Regional Park. Our work reinforces the 1972 City Council decision designating these afforestation areas on the western fringe of Saskatoon to “be preserved in perpetuity.” They are important habitat for wildlife as well as semi-wild public spaces for recreation and nature immersion. The larger of these two areas is named after Richard St. Barbe Baker (1889-1982), who has been called the “first global conservationist” and in recognition of this he was made the first Honorary Life Member of the World Wildlife Fund in 1969. A British forester who also homesteaded and studied in Saskatoon, he dedicated his entire life unfailingly to the preservation and planting of trees and forests. This is one session in a weeklong series of webinars. Our goal is to promote discussion about trees and forests, and their multiple and essential benefits. The health of trees is being affected by climate change but trees are also a necessary solution in mitigating it. We aim to raise awareness about what trees and forests give us and what we need to do in return to protect and enhance trees and forests.
