Little Red Riding Hood lied:  Wolves are not vicious killing machines.  In fact, there are no documented instances of a healthy, wild wolf killing a human being in North America. Wolves are an integral part of the natural food web, and their continued presence is necessary for healthy ecosystems. 

What Good Are Wolves, Anyway?

Wolves are an integral part of their ecosystems. As large predators, they affect other predators, prey, scavengers, and even vegetation. Their return to an ecosystem can increase the stability and biodiversity of that system. Wolves can increase biodiversity by competing with other predators, especially coyotes, for prey and territory. When coyote populations decrease because of this, the small mammals and birds on which they prey benefit1-3. The presence of wolves can also increase biodiversity through their ‘leftovers’. The remains of wolf prey are eaten by bears, foxes, weasel, raptors, and other scavengers. 

Wolves can improve the gene pool of their prey species through time by culling genetically inferior individuals, such as the slow, the weak and the sickly4. Wolves also help to control the population sizes of their prey.  In the case of herbivorous prey like deer and elk, wolves indirectly protect sensitive plants by keeping the prey population in check5. All of this contributes to a healthy and thriving ecosystem. 

Wolves have a long history of reverence from native cultures. Contemporary Americans are experiencing a resurgence of interest in wolves and other large animals. Not only do we enjoy biodiversity and healthy ecosystems, we like to look at and learn about majestic animals like wolves. Wolf-related tourism can provide an economic boost to the economies of regions where wolf populations are thriving.
 




Why Do Wolves Need Our Help?

Centuries ago, wolves were found all across the North American continent. Due to trapping, hunting and other "wolf control" measures, wolves were gone from most of the United States by the early 1970's. The Gray Wolf was listed as endangered by the U.S. Fish & Wildlife Service in 1974, and since then, wolf populations have grown  in some states. Despite opposition from conservationists who argue that wolf populations have not recovered sufficiently, the U.S. Fish & Wildlife Service has proposed reclassifying the gray wolf (lessening the level of protection it receives), with total de-listing an imminent possibility. When de-listing occurs, the USFWS will turn management of the gray wolf over to the states.  States must have an approved plan for the continued management and protection of the gray wolf. 

Some states offer management plans for the caretaking and protection of the wolf that include input from a wide variety of stakeholders.  Livestock producers, hunting groups, conservation organizations and people who share the land inhabited by wolves all have had a say in the state management processes, to varying degrees.  Although many states’ plans address these citizens’ concerns, not all the plans are positive.  Mixed in with the positive measures to protect the wolf are negative measures intended to diminish them. This package provides an overview of the various plans and offers the tools necessary for you to promote wolf conservation in your state.

Defenders of Wildlife – a SERC partner group -- has been a leader in wolf conservation. In recent years, Defenders helped restore Gray Wolves to the northern Rockies and played key roles in the reintroduction of Mexican Wolves to the Southwest and Red Wolves to the Southeast.   You can learn more by visiting their wolf information webpage
