Many wild animals, such as the wood duck and the pronghorn, were managed back to abundance from the brink of extinction. Today most wild animals in the United States are being effectively conserved. However, much remains to be done internationally with animals such as the elephant, panda, and rhino. Wildlife management today emphasizes managing ecosystems so that all components, from butterflies to birds, remain healthy. Reintroduction of the wolf into Yellowstone will restore an ecosystem damaged by humans.
All states have a governmental agency responsible for that state's non-migratory wildlife.
Most wildlife managers work for agencies like the Ohio Division of Wildlife in a wide variety of jobs. Private groups that hire wildlife professionals include enormous diversity, ranging from the Audubon Society to the National Wildlife Federation. Membership in private conservation organizations has increased dramatically in recent years, as has the hiring of wildlife biologists. Careers include management, law enforcement, and research. The first two job types generally require a BS degree.
