This report provides an update on marsh bird and amphibian population trends from 1995 – 2000 derived from six years of MMP implementation across the Great Lakes basin. It provides an overview not only of general trends and annual variation in marsh bird and amphibian annual population indices, but also provides insight into how annual water level changes of the Great Lakes have been related to annual changes in several species of marsh birds and amphibians commonly encountered at Great Lakes coastal marshes and at more isolated interior marshes.  This report demonstrates the value of MMP data collected to date and how citizen scientists throughout the Great Lakes region are playing an important role to address many previously unanswered question pertaining to marsh bird and amphibian population conservation.  This report provides further appreciation to the agencies and foundations supporting the program through the years. Most importantly, this report compliments the previous MMP Five-year report by conveying to the hundreds of Great Lakes citizens who have volunteered with the program that their contributions are both highly valued and extremely important.
