There is strong public interest in wildlife conservation and, along with that interest, high expectations. A 2011 national survey by the U.S. Fish and Wildlife Service (http://digitalmedia.fws.gov/cdm/singleitem/collection/document/id/858/rec/10) found that, in addition to $797 million spent on hunting and fishing in Wyoming, over $350 million was added to the State’s economy by wildlife watchers. Wyoming is also rich in other natural resources that contribute to our economy, such as livestock forage; timber; a variety of minerals; and oil, gas, and coal. However, sometimes the best management of one or more resources can conflict with the needs of another. Over the past few decades, public expectations of wildlife managers have diversified.
