12B Water -
More Than Just Your Backyard Pond

Conservation, Royal Botanical Gardens
Backyard ponds
have the potential to be extremely valuable in support of both
regional biodiversity and water management. The context for this is
based in historical land use changes in southern Ontario where
marginal water bodies (wetlands) were filled and dredged, breaking
ecological linkages and reducing the landcape's ability to attenuate
floodwaters. As an example, around Lake Ontario over 80% of the
wetlands have been lost and very few aquatic systems remain
functional. The relevance of the value of the backyard pond is
magnified by the fact that private land owners are more likely to
ensure private ponds have clean water when compared to public rivers
or lakes. The result is environmental systems, particularly those
linkages associated with amphibians and migratory birds, can be
substantially improved with an appropriately designed backyard pond.
