The U.S. Fish and Wildlife Service (FWS) and the National Park Service (NPS) are preparing a management plan for bison and elk inhabiting the National Elk Refuge (NER) and Grand Teton National Park (GTNP). These animals are part of the bison and elk herds in Jackson Hole, one of the largest concentrations of free-ranging bison and elk in the world. A range of alternatives for managing the bison and elk herds in the project area will be developed in an Environmental Impact Statement. The EIS will include an analysis of elk hunting programs related to the NER and GTNP. Management of the Jackson elk herd on the NER and GTNP can impact the number of hunters allowed and hunter harvest ratios on NER, GTNP, and Bridger Teton National Forest (BTNF). To assist the EIS planning effort, the U.S. Geological Survey (USGS) in cooperation with the Wyoming Game and Fish Department (WGFD) conducted a survey of elk hunters that hunted within the Jackson elk herd unites during the 2001 hunting season. The objective of this survey and analysis was to quantify how much hunters spent in the local and regional economy and the associated economic aspects such as income and employment effects. Spending by elk hunters in the Jackson area generates considerable economic benefits for the local and regional economy. An elk hunter usually buys a wide range of goods and services during a hunting trip. Major expenditure categories include outfitter/guide fees, hunting licenses and supplies, game processing, lodging, food, and gasoline. As more hunters come to an area, local businesses will purchase extra labor and supplies to meet the increase in demand for additional services. The income and employment resulting from purchases by hunter at local businesses represent the direct effects of hunter spending within the economy. In order to increase supplies to local businesses, input suppliers must also increase their purchases of inputs from other industries. The income and employment resulting from these secondary purchases by input suppliers are the indirect effects of hunter spending within the local economy. The input suppliera s new employees use their incomes to purchase goods and services. The resulting increased economic activity from new employee income is the induced effect associated with hunter spending. The indirect and induced effects are known as the secondary effects. Multipliers capture the size of the secondary effects, usually as a ratio of total effects to direct effects (Stynes, 1998). The sums of the direct and secondary effects describe the total economic impact of hunter spending in the local economy?
