University of Minnesota Extension has developed By Land and By Sea: Identification Guide to Non-Native Species for Minnesota to offer an all-inclusive field guide for invasive and potentially problematic species. This new resource includes 86 species in seven major categories: Aquatic Animals, Birds, Insects, Worms, Aquatic/Wetland Plants, Herbaceous Plants, and Woody Plants. It clearly defines important terms including non-native, invasive, and weed, and provides important information about state law, as well as the best methods for reporting invasive species.
