However, many conservation scientists and wolf advocates believe that more time on the endangered species list -- and [under] federal protection -- would allow wolves a greater opportunity to reclaim more of their former territory and grow the number of their populations. This is important because, despite wolf recovery success in the Great Lakes states and Rocky Mountains, there is still a lot of their former range not yet occupied. Expanded range and more populations, in turn, will provide greater species resiliency to unexpected environmental disruptions like climate change and emerging diseases and also improve long-term wolf survival in the U.S.

An independent review panel recently found that the federal government used uncertain science when it proposed removing the gray wolf from the endangered species list across the lower 48 states. What could that mean for the future of wolves?
This is important because under Endangered Species Act law the U.S. Fish and Wildlife Service is obligated to use the best available science. The Service claimed that new genetic research indicated that wolves living in the eastern U.S. were actually a different species, and thus should not be considered as part of the original listing or part of the historic range. The expert panel said the genetic research was uncertain and based largely on one paper. The panel’s report has reopened the debate about delisting gray wolves, and I suspect it will extend the time wolves remain listed. The final decision on delisting is yet to be determined -- public comment is encouraged. [Note: deadline is March 27, 2014]

In the long run, the debate about delisting wolves invites larger questions like, what constitutes full recovery of any endangered species, and does the legal framework of the ESA reflect current conservation science and principles of sustainable living? Most importantly, there needs to be agreement at the onset about the ultimate purpose of recovery -- is it simply species survival or restoring ecological function? There are no easy answers.

Is it possible for wolves and humans to coexist? What needs to change for that to happen?
I think that wolves and humans ultimately will coexist by sharing land in two key places -- protected areas and rural areas managed for the benefit of people and wildlife, for example, park buffer lands, multiple-use public lands, and designated wildlife corridors. For the reconciliation between wolves and humans to prove fully successful, we will first need a broader understanding of the role that apex predators play in creating healthy ecosystems and why healthy ecosystems are needed by people. In other words, there must be a broader understanding of why saving wolves is essential to sustainable living. Greater public will to save wolves will result in increased public spending needed to conduct science and carry out sound management actions. For example, we need more research on improving ranching practices to minimize wolf predation of livestock, and insurance programs that compensate ranchers for unavoidable losses. There is already good evidence from pilot efforts that such research and management programs are possible -- and that they work!

Why should people care about the fate of wolves?
The fate of wolves is tied directly to the greatest challenge facing humankind this century -- sustainable living! With more than seven billion people consuming resources at an accelerating pace, this generation of world citizens must transform our societies to sustainable ones. We must, among other things, protect a wide variety of animal and plant species -- scientists call this “biodiversity.” Many conservation scientists believe that apex predators (animals at the top of the food chain), like wolves, are necessary to maintain habitats rich in life. In turn, high levels of biodiversity bring many direct benefits to people -- everything from providing food and fiber to protecting water supplies and enriching recreation.

Understanding the links between apex predators and biodiversity is a growing area of research for scientists like Aaron Wirsing of the University of Washington. Since 2008, wolves have been returning to Washington and have reestablished populations in the U.S. northern Rockies. This has provided a unique research opportunity for Wirsing and other scientists. For example, deer populations in Washington have likely over-browsed plants for decades in the absence of gray wolves. One consequence of deer eating trees along streambeds is less habitat for birds, and streams that are more likely to harbor fewer cold-water fish like trout because they are filled with sediments from soil erosion and overheated because of lack of shade. With wolves back in the state, Wirsing is leading a study to document how wolves are changing mule and white-tail deer populations, which in turn affects forest landscapes.

Why do you care about wolves?
I care about wolves because as apex predators they contribute significantly to enriching biodiversity needed by people for sustainable living. I also care about wolves because I admire them! Wolves are amazing for many reasons, but I am especially fascinated by their complex social behavior and adaptable lifestyles, two traits that they share with humans. Also, one of the most important reasons I care is that wild wolves in the U.S. are a symbolic way of keeping our American heritage of wilderness alive.
