Proceed with Caution Spring is a wonderful time to explore the trails of the Don and its tributaries by bicycle or on foot, but it's also the time that going off-trail can cause the greatest damage. So please keep bicycles on the trails, and, if you go off-trail, walk very cautiously and lightly. The Don is not a wilderness setting, and wherever you blaze a path, a hundred more are likely to follow. Goes without saying. They'll provide valuable habitat for songbirds and butterflies.
Duckweeds are among the smallest plants in the world.
The duckweed floating in the Riverdale Ponds in the late summer is common duckweed. Common duckweed are less than 6mm across, green above and below, and they float singly or in clusters on the water surface. Duckweed will reproduce abundantly in quiet water. They are an important food source for waterfowl, beaver and muskrat which extensively feed on the entire plant. This plant doesn t harm the newly restored pond system at Riverdale Farm and is a common plant found in natural systems.
