Great Lakes salmon are the focus of new video series (4/4) Underwater footage of wild-spawned salmon in Michigan streams show the challenges faced by young fish. Participants in MDNR’s Salmon in the Classroom program can use this series as a refresher on the salmon’s life cycle and Great Lakes ecology.
Trumpeter swans at risk in shrinking lakes Midland Mirror (4/2) The deaths of two trumpeter swans from lead poisoning in Georgian Bay this year are raising questions about the environmental impact of decreasing water levels in the Great Lakes.
The environment of the Great Lakes region is blessed with huge forests
and wilderness areas, rich agricultural land, hundreds of tributaries
and thousands of smaller lakes, and extensive mineral deposits. The
region's glacial history and the tremendous influence of the lakes
themselves create unique conditions that support a wealth of biological
diversity, including more than 130 rare species and ecosystems.
The environment supports a world-class fishery and a variety of
wildlife, such as white-tailed deer, beaver, muskrat, weasel, fox, black
bear, bobcat, moose and other furbearing animals. Bird populations
thrive on the various terrains, some migrating south in the winter,
others making permanent homes. An estimated 180 species of fish are
native to the Great Lakes, including small- and large-mouth bass,
muskellunge, northern pike, lake herring, whitefish, walleye and lake
trout. Rare species making their home in the Great Lakes region include
the world's last known population of the white catspaw pearly mussel,
the copper redhorse fish and the Kirtland's warbler.
The region's sand dunes, coastal marshes, rocky shorelines, lakeplain
prairies, savannas, forests, fens, wetlands and other landscapes contain
features that are either unique or best represented withink the Great
Lakes basin. For example, the world's largest freshwater dunes line the
shores of Lake Michigan.
Over the course of history, many types of pollution have inflicted and
been reduced in the region, yet significant challenges remain. These range from
threats to divert water out of the Great Lakes basin to the introduction
of nonindigenous invasive species and airborne toxics into the basin.
Protection of water quality and sustainable development remain long-term
