The Effects of Fragmentation on Biodiversity of Coastal Wetlands.

The Michigan Legislature enacted legislation in 2  3 allowing beach  grooming of  exposed bottomlands by owners of lakefront property on  the Great Lakes and Lake St. Clair. Beach maintenance activities  were allowed between the ordinary high water mark and the existing  water?s edge without a permit unless mowing in excess of 1   feet of  frontage was planned. Mechanical removal of certain types of  vegetation was also allowed but was restricted to "pilot" areas and  required a letter of approval from the Director of the Michigan  Department of Environmental Policy (MDEQ) before being undertaken.  The Director of MDEQ designated Saginaw and Grand Traverse Bays  as "pilot areas".  No mowing or mechanical removal of vegetation was  allowed in Designated Environmental Areas. This legislation directed  MDEQ to determine the impacts of beach grooming. Our objective in  this proposal was to conduct research to determine impacts on  groomed beaches and adjacent wetland ecosystems. Particular emphasis  was on the effects of fragmentation caused by beach grooming on  invertebrate and fish populations in and adjacent to groomed areas.  However, direct effects of mowing and plant removal on erosion of  beach areas and the combined effects of these activities on  invertebrate, fish and plant communities were also examined.
