Wisconsin at a glance
Gray wolves once existed throughout Wisconsin, but their numbers began to decline soon after European settlement. From 1865 to 1957, wolves were primarily removed through shooting and trapping. After being protected under the Endangered Species Act in 1974, wolves immigrated from Minnesota and established territories in Wisconsin. According to federal recovery criteria, the wolf population in Wisconsin has been considered biologically recovered for several years. In January 2012, they were delisted from the endangered species list and managed at the state level until December 2014, when they were placed back on the list.
Wolves were again delisted in January 2021 and are currently managed by the state’s Department of Natural Resources. A wolf hunt took place in February 2021. However, following a federal court ruling on February 10, 2022, gray wolves were listed as an endangered species across the lower 48 states (excluding the northern Rocky Mountains) and are now federally protected. As a result, harvesting and lethal control of wolves are prohibited.
Public attitudes toward wolves are generally positive, but the subject remains controversial. In recent years, about 25% to 50% of wolf mortality has been attributed to illegal killings by humans. Wolves primarily prey on deer, beavers, and turkeys, especially in central regions of the state. They inhabit the northern portion and a small central area known as the central forest of Wisconsin.
