Public values of aquatic invasive species management

The overall goal of this project is to quantify and analyze the ecological and economic value of AIS damages and AIS management as they relate to ecosystem services such as fishing, swimming, biodiversity, and navigability. Researchers will employ a multi-pronged approach, including:

  • Estimating public benefits of AIS management
  • Analyzing costs of carp management and effectiveness of carp management as a strategy for water clarity restoration
  • Developing a broad AIS analysis framework, which we will use to estimate efficient carp management

Specific outcomes of the study include a comprehensive AIS valuation data compilation for use by other researchers, and an eco-economic programming model to predict the economic and ecological repercussions of using AIS prevention and control initiatives.

This project is important because even if the direct costs of AIS management are known, a lack of information about the potential benefits of AIS management makes informed decision-making difficult. With an accurate assessment of the costs and benefits of AIS management strategies, as well as information on public perception, resource managers will be better prepared to efficiently and effectively invest management resources.

Progress:

As of January 2019, a literature review to identify key survey topics was complete, along with samples of survey questions in order to identify survey topics and develop the questionnaire for Minnesota residents. Researchers have also been working with watershed districts to collect information about cost estimates and water quality before and after AIS management efforts. Survey collection will kick off in summer 2019.
