This Rambles with Robin and Ruby video looks at the geological processes that created ancient raised or stranded beaches and the types of vegetation that grow on the beaches and adjacent muskeg. The video includes quite a bit of geology, but as a context to help understand the habitats of plants that grow in this ecotone between the Canadian Shield and the James Bay lowland.
Did you know there was an inland marine sea that once covered a large area of northern Ontario, in Canada?
Did you know that marine sea was responsible for the creation of many sandy beaches located up to 250 km away from Hudson Bay or James Bay?
Did you know those beaches are habitats for plants today?
If not, perhaps this video will be of interest to you.
This area lies within the traditional homelands of Moose Cree First Nation, within the area of Treaty #9.
