Plants have a lot to tell us about our environment. Over the years Ecology North has been involved with a number of projects studying local plants, their role in the ecosystem, and the effect that climate change is having on their natural rhythms.
NatureWatch developed PlantWatch booklets to help people to better understand the plants of the north and to monitor changes. You can visit their website here (https://www.naturewatch.ca/plantwatch/) where you can download PlantWatch recording sheets and find tons of helpful plant ID info and more information about more citizen science programs.
