Houghton Lake is the largest inland water body in Michigan, and as such, is a major ecological and recreational resource for the region. Results of a survey conducted in October 1999 indicated that over 4,000 ha of the lake had become infested with the exotic submersed plant Eurasian watermilfoil (Myriophyllum spicatum L.). Local concern regarding the problems associated with the Eurasian watermilfoil infestation centered on its future impact on recreational opportunities, fish and wildlife resources, and ecological health of the lake. In 2001, the U.S. Army Engineer District, Detroit, was tasked by Congress to assist the Houghton Lake Improvement Board (HLIB) in the development of a draft plan for managing Eurasian watermilfoil on the lake. Therefore, a workshop was held to review operationally viable techniques for managing Eurasian watermilfoil in Houghton Lake, and discuss environmentally sound options for managing this invasive plant. Management options considered included the use of chemical herbicides currently registered in the state of Michigan; the use of the milfoil weevil, a biocontrol agent; the use of mechanical harvesters; and an integration of these techniques. In addition, impacts to water quality and fish and wildlife resources were considered. The objective of this report is to summarize and present information from the workshop and other sources that will provide guidance for the environmentally sound management of Eurasian watermilfoil in Houghton Lake.

Minnesota comes alive in the pages of Wild Minnesota. Wild Minnesota contains more than 150 full-color photographs of Minnesota's natural wonders. Author Shawn Perich and photographer Gary Alan Nelson traveled thousands of miles to give us this photographic portrait of the diverse and unique natural areas of our state. Minnesota is often thought of as the state of 10,000 lakes, but it is much more. It is the peaks of the Sawtooth mountain range along the North Shore and the winding mighty Mississippi in the east. It is the rainbow palette of wildflowers and native grasses of the prairies and the spectacular limestone bluffs of the southeast. It is the acres of pine forests of Itasca State Park and the Red River valley's exceptionally rich soil. Wild Minnesota is the natural beauty of our state; it is what we see, hear, and feel as we paddle one of the many unspoiled lakes of the Boundary Waters Canoe Area, hike the Superior Hiking Trail, view the tremendous diversity of wildlife in the Agassiz National Wildlife Refuge. It is the call of the loon on Mille Lacs, the pounding of a powerful wave on the Lake Superior shore, the experience of history through the rock outcroppings of the Jeffers Petroglyphs. It is that still, golden late summer afternoon when you know the Gopher state is where you're meant to be.

Biological invasions are one of the strongest drivers of global environmental change, and invasive species are now often in the public discourse. At the same time, economists have begun to take a real interest in determining how invasive species interact with economic systems, and how invaders should be controlled to optimize societal wealth. Although the work from ecologists and economists have both greatly expanded our understanding of the drivers and impacts of invasions, little integration between the fields has occurred that would allow managers and policy-makers to identify the optical expenditures on, for example, prevention and control of invasive species. Because the level of effort expended on invasive species management is intricately linked to the costs and projected benefits of that management, there is an urgent need for greater synthesis between ecology and economics. This book brings ecology and economics together in new ways to address how we deal with the dynamics and impacts of invasive species, and is the outcome fo many years of collaborative research between a small group of economists and ecologists. The outcome is clear demonstration of the utility of combining ecological and economic models for addressing critical questions in the management of invasive species.
