Welcome to the Ontario South West Region Envirothon

This region includes the following school boards: Thames Valley District School Board, London District Catholic School Board, St. Clair District School Board, Lambton-Kent District School Board, Greater Essex Country School Board, St. Clair Catholic District School Board, and Windsor-Essex Catholic District School Board.

Due to the COVID-19 pandemic, the 2021 Provincial Envirothon will be held virtually. More information on the Provincial Envirothon will be provided at a later date.

Every year, the South West Region is hosted at the Springwater Conservation Area (just outside of Aylmer, Ontario). However, due to the pandemic, this year we will be hosting our regional Envirothon virtually! The layout of this Envirothon will be slightly different, but has allowed more accessibility to participating school boards. We hope by hosting the 2021 South West Region Envirothon virtually, more schools will be able to participate (dependent, of course, on COVID-19 and health unit guidelines).

On this website you will find links to resources, videos, as well as information regarding our competition. Information will be posting periodically, so please keep checking back! If you have any questions regarding the South West Region’s Envirothon, please contact Ron Casier at

Climate Change: Nature-Based Solutions

From the Forests Ontario Website:

“From forests to cities to wetlands, climate change is impacting natural and man-made systems around the world. A complex and widespread societal challenge, we need solutions that address climate change issues from multiple angles – and nature-based solutions could be part of the answer.

Nature-based solutions are a broad category of actions that work with, and help to enhance, natural systems to address challenges such as a loss of biodiversity and ecosystem degradation. The 2021 Ontario Envirothon program will focus on this emerging area to explore how natural systems can be used to capture carbon and mitigate climate change impacts.”
