There are more than 180 exotic species in the Great Lakes. Some,
such as green algae, the Asian tapeworm, and the suckermouth
minnow, have had little or no impact so far. But a handful of
others-sea lamprey, alewife, round goby, quagga mussel, zebra
mussel, Eurasian watermilfoil, spiny water flea, and rusty
crayfish-have conducted an all-out assault on the Great Lakes and
are winning the battle. In Lake Invaders: Invasive Species and the
Battle for the Future of the Great Lakes, William Rapai focuses on
the impact of these invasives. Chapters delve into the ecological
and economic damage that has occurred and is still occurring and
explore educational efforts and policies designed to prevent new
introductions into the Great Lakes. Rapai begins with a brief
biological and geological history of the Great Lakes. He then
examines the history of the Great Lakes from a human dimension,
with the construction of the Erie Canal and Welland Canal, opening
the doors to an ecosystem that had previously been isolated. The
seven chapters that follow each feature a different invasive
species, with information about its arrival and impact, including a
larger story of ballast water, control efforts, and a
forward-thinking shift to prevention. Rapai includes the
perspectives of the many scientists, activists, politicians,
commercial fishermen, educators, andboaters he interviewed in the
course of his research. The final chapter focuses on the stories of
the largely unnoticed and unrecognized advocates who have committed
themselves to slowing, stopping, and reversing the invasion and
keeping the lakes resilient enough to absorb the inevitable attacks
to come. Rapai makes a strong case for what is at stake with the
growing number of invasive species in the lakes. He examines new
policies and the tradeoffs that must be weighed, and ends with an
inspired call for action. Although this volume tackles complex
ecological, economical, and political issues, it does so in a
balanced, lively, and very accessible way. Those interested in the
history and future of the Great Lakes region, invasive species,
environmental policy making, and ecology will enjoy this
informative and thought-provoking volume.
