News
How the Crawfish Became a Conservation Flashpoint
Crayfish have become symbols of ecological integrity and conflict, highlighting the delicate balance between preserving biodiversity and managing invasive species in our rivers and wetlands.
A tale of two landscapes and one Aquatic Invasive Species Detector’s mission
Bob McNamara dedicates his summers to protecting Minnesota’s waterways from invasive species like rusty crayfish. He does this through the University of Minnesota Extension’s AIS Detectors program, blending his passion for photography and conservation.
Free AIS Monitoring Workshop in Washburn County, Wisconsin
The Washburn County Land and Water Conservation Department is hosting a free Aquatic Invasive Species monitoring workshop on May 9 from 5pm to 7pm at Washburn County Services Center. To register, contact Lisa Burns at lbu...@co.washburn.wi.us.
This selection of invasive crayfish information is collected by the Invasive Crayfish Collaborative, a program convened and facilitated by Illinois-Indiana Sea Grant and the Illinois Natural History Survey with funding from the Great Lakes Restoration Initiative.
