So What’s the Problem?
There are many shorelines where the banks were long ago stripped of the native plant community, including trees and
shrubs, and converted to turf grass-type lawns. The loss of this vegetation encourages soil erosion and nutrients to ow directly to
the lake. As these practices spread around a lake, there are fewer areas left to treat runoff water and provide habitat. Studies
of Minnesota lakes have shown that the removal of natural vegetation near the shoreline reduces the amount of habitat available
to songbirds and amphibians and reduces sh-nesting. Many of these problems could be prevented or minimized if an area of
native plants is maintained or restored.
Shoreland ordinances allow a limited number of trees and shrubs to be cleared to accommodate stairways and access paths.
However, the applicable standard for such removal is that the screening of structures, vehicles or other facilities as viewed
from the water may not be substantially reduced. Dead or diseased vegetation can be removed although they may be important
for songbirds and other wildlife. Invasive species can be an overwhelming problem both on the shore and in the water. The
local zoning ofce or DNR area hydrologist should be contacted for guidance before proceeding with any lakeshore alterations
or removal of live vegetation.
• Protect the health of the vegetation growing on your property.
• Invasive species tend to spread rapidly. Learn to identify the most common invasive species.
Invasives should be removed, but replanting native species may be needed to protect shorelines
from erosion.
• Use herbicides that are labeled for an aquatic site or use a more precise method of application,
like a wick applicator or a cotton glove over the top of a chemical resistant glove to apply the
product only to those plants you want to control.
• Leave vegetation in place to screen structures, vehicles or other facilities as viewed from the water.
• Consider leaving dead or diseased vegetation in place as they may be important for songbirds and
other wildlife.
• Most importantly, leave an area of native plants between the house and the shoreline area. Limit the removal of trees
and shrubs.
• If you have been mowing near the shoreline, simply discontinue that practice to allow growth of native plants or restore
and replant with native owers, shrubs or trees.
Contact the local Soil and Water Conservation District, DNR area hydrologist or your county zoning ofce to get assistance.
There are also a number of books and “on-line tools” (Restore Your Shore http://www.dnr.state.mn.us/restoreyourshore/in-
dex.html and Score Your Shore http://www.dnr.state.mn.us/scoreyourshore/index.html) and other literature available to help
you support shorelines that promote healthy lakes and streams and the biotic communities that depend on them.
