The Rice Lake Plains are found in the eastern-most segment of the Oak Ridges Moraine, south of Rice Lake. This area contains some of the largest examples of kame moraine forests, prairies and savannahs in Ontario. Historically the Rice Lake Plains were dominated by prairie and savannah which covered at least 42,500 acres (17,200 ha). Black oak savannah and tallgrass prairie vegetation communities, which were once common in southern Ontario, have now been ranked as globally rare and are classified as critically endangered in many U.S. states. Less than 3% of the original extent of these habitats remains in Ontario, which is why their restoration is critical.
