Climate change is expected to severely alter aquatic ecosystems in the Mid-Atlantic US states, including increasing water temperatures, reducing average stream flow, and an increase in the severity of rainstorms and flash flooding. As is the case with several other human-driven threats to freshwater ecosystems, climate change will act as a “threat multiplier,” intensifying the adverse effects of invasive species while also acting to facilitate new invasions. Aquatic invasive species cost the global economy US$345 billion per year and these costs are expected to increase exponentially in the coming decades. Invasive fish managers will need to actively address a changing climate when conducting monitoring, eradication, and other invasive management efforts to ensure they remain effective.

New Jersey has experienced a rise in the number of established aquatic invasive species over the last two decades, and in response has made substantial advancements in coordinating control and management efforts across the state. Professor Julie Lockwood and Dr. Mario Hernandez are developing recommendations for managers to consider when developing new management plans or modifying existing plans to better handle the effects of a changing climate on invasive fish management. “Climate-smart” management refers to actions taken to address control of invasive fish populations while also considering expected climate change trends. This project is being conducted in collaboration with the NJ Department of Environmental Protection’s Bureau of Freshwater Fisheries and Division of Science and Research biologists to develop useful and feasible considerations for all future invasive fish management plans.
