Understanding Impacts of Invasives

Sociological and Economic Impacts of AIS

Thursday 2:00-2:50pm

What Determines Lake Residents Awareness & Knowledge of Aquatic Invasive Species? Can environmental stressors represent threats to your economic well being or quality of life? This presentation summarizes findings based on data collected around the Pike Lake Chain of Lakes in Bayfield County, Wisconsin, where both full- and part-time residents were surveyed in order to collect a wide variety of information. We will look at how economic research tools may be used to assess lake residents awareness and knowledge of AIS as well as their likely behavioral changes.
Presenter: Mark Eiswerth, University of Wisconsin - Whitewater
 
What are the effects of Aquatic Invasive Species on Property Values? This presentation will explain a study using hedonic analysis to estimate the effects of a common aquatic invasive species Eurasian Watermilfoil (milfoil) on property values across an extensive system of over 170 lakes in the northern forest region of Wisconsin. Results obtained by examining property values on lakes before-and-after invasions indicate that lakes invaded with milfoil experienced an average 13% decrease in land values after invasion. Implications for invasive species policy will be discussed.
Presenter: David Lewis, UW Madison Department of Ag & Applied Economics
 

Management & Control of AIS - Research Findings

Long-term trends in Eurasian Water Milfoil Management

Thursday 2:00-2:50pm

In this session we will look at aquatic plant community responses with various management tools to address invasives, the importance of aquatic plant monitoring and using good data to make management decisions. Wisconsin's long-term Eurasian water milfoil research project and results from case studies to evaluate the effectiveness of early-season chemical treatments to control EWM will also be discussed.
Presenters: Dr. Jennifer Hauxwell, Alison Mikulyuk, and Michelle Nault, Wisconsin Department of Natural Resources Science Services Bureau.
 

Success Stories

Innovation in Carp Management at Big Green Lake

Thursday 2:00-2:50pm

For many years, carp have been a major problematic invasive specie to many lakes including Big Green Lake. Due to the logistics of our lake’s main tributary (Silver Creek), it became apparent that any type of carp barrier structure would need to accommodate some regular boat traffic. Consequently, over the past few years the Green Lake Sanitary District (GLSD) in conjunction with an innovative business concern has developed an air carp barrier that does the job of disrupting carp passage; while also allowing safe, reliable and easy passage for boats going across it. Charlie Marks will provide a video of the innovative air carp barrier along with information on its development and its effectiveness.
 
Presenter: Charlie Marks, Green Lake Sanitary District
 

Country/Regional AIS Strategies

AIS Coordinators: Valuable Parts of AIS Strategies

Thursday 2:00-2:50pm

These two Aquatic Invasive Species Coordinators will give their direction and perspectives on approaches to invasive species programming in your county. They will discuss the grant process, working with county & local leadership and problem solving techniques.
Presenters: Audrey Greene, Walworth County; and Tom Ward, Manitowoc County

Invasives at the Water's Edge & in the Great Lakes

Managing Invasive Species in Wisconsin’s Door Peninsula

Thursday 2:00-2:50pm

Wisconsin's Door Peninsula harbors some of the highest levels of biodiversity in the Great Lakes region. With hundreds of miles of Great Lakes shoreline, inland lakes, and many thousands of acres of wetlands, numerous kinds of invasive species pose a serious threat to the health and sustainability of Door County's wet ecosystems. This presentation will give an overview of community efforts to control the spread of invasive species in Door County, including: genesis of Door County Invasive Species Team (DCIST), the many partnerships forged to address this problem, and the current status of control efforts.
Presenter: Bob Bultman, Door County Invasive Species Team Coordinator
