Life on the Edge...The importance of shorelines

Central Ontario is blessed with an abundance of waterways; lakes, rivers, creeks, and wetlands. We depend on this water to provide irrigation for crops and gardens, recreational opportunities such as boating and swimming, and in some cases, to provide a safe drinking water supply.


But we aren't the only ones who enjoy the benefits of waterfront areas. Many species of wildlife depend on the continuation of healthy aquatic ecosystems especially the rich yet fragile shoreline area. Water lilies, loons, frogs, mink, and fish all need healthy shorelines to survive.


The area where land and water meet, the riparian zone, is often called "the ribbon of life" because of its significance in the ecosystem. Fish and aquatic invertebrates lay their eggs, raise their young, feed, and find shelter in the plants and natural debris found in the riparian zone. Protecting this zone is also important for overall water quality.


Unfortunately, shorelines are under threat by development of waterfront homes and cottages. It is important for all waterfront property owners to practice good stewardship to ensure the continued health of our lakes and rivers for generations - of humans and wildlife - to come.


Here are some suggestions on ways to be friendlier to our shoreline:

     1  Avoid alteration of shorelines as much as possible and leave much of the natural vegetation in place. This will provide wildlife habitat, reduce erosion problems, and create a buffer between          structures and waterways.

     2  For a view of the water; instead of cutting down trees, why not leave the trees up but trim the lower branches. You could also plant low-growing native shrubs such as red-osier dogwood or           blueberries.

     3  Avoid creating a sand beach over top of natural lake and river bottoms. The dumping of sand along the water's edge could cover up fish spawning sites and adversely affect other aquatic life.

     4  If you are putting in a dock install the floating or cantilever type or docks with pipes or wooden supports. These designs have little or no impact on the lake bottom and don't restrict the movement          of water near the shore. Avoid crib or concrete docks.

     5  Avoid the use of fertilizers, even natural ones, near the shoreline area as fertilizers can easily be washed into the waterway upsetting the natural balance of nutrients. An excess of phosphorous          could result in an unsightly and potentially harmful algal bloom.

     6  Learn more about the wide variety of plants and animals living along the shoreline. Understanding more about the natural world is not only fascinating but can also be a relaxing pasttime.
