| The Leafy Spurge Biological Control program was designed to use insects and plant diseases from the plant's original European habitat to control infestations in the United States. The widespread adoption of biological agents to combat leafy spurge and the initial success in reclaiming previously infested land has prompted an evaluation of the potential future economic benefits of the biological control of leafy spurge in the Upper Midwest. Based on expert opinion and historical data, leafy spurge in Montana, North Dakota, South Dakota, and Wyoming was projected to infest 1.85 million acres, of which, 65 percent was estimated to controlled with biological agents by 2025. Based on a survey of county weed board personnel, North Dakota and Wyoming are... |

| The economic impact of three invasive, exotic weeds--diffuse, spotted, and Russian knapweed (Centaurea diffusa, C. maculosa, and Acroptilon repens)--on Montana's economy was estimated using a procedure developed for another invasive weed species. Published data and that from a survey of county weed boards were used to estimate direct negative impacts of over $14 million annually due to infestation of over 2 million acres of rangeland and wildland. This amounts to about $10.63 on each infested grazing land acre and $3.95 on each infested wildland acre. Direct plus secondary economic impacts, estimated using an input-output model, are about $42 million annually, which could support over 500 jobs in the state's economy. This first approximation suggests... |

| Wildlife-related recreation is an important source of economic activity in North Dakota. Using primary, survey-based data, the expenditures and economic impacts of hunters and anglers were summarized for the 1996 hunting/fishing seasons. Total resident and nonresident expenditures (including cost of licenses and additional nonresident expenditures not related to hunting/angling) came to $594 million. Almost $144 million of total expenditures was spent in rural areas by nonresidents and urban residents. Resident and nonresident hunters and anglers generated $1.6 billion in total business activity, $250 million in retail trade sales, $393 million in personal income, and supported over 21,000 jobs. These results suggest that North Dakota's resident and... |

| This study was initiated when a need for data on nonresident hunter expenditures and activities was identified in a departmental research effort considering alternative uses of wetlands. Also, nonresident hunting license sales are an important source of revenue for the North Dakota State Game and Fish Department. In 1976, 7.5 percent of the hunters in the state were nonresidents, but nonresident license sales accounted for 27 percent of all state hunting license revenue. The data in this report fill a void that existed in estimating the economic significance of all hunting in North Dakota since a similar study dealing with resident hunters was conducted in the department in 1973. |
