| Leafy spurge is an exotic, noxious, perennial weed which is widely established in the north central United States and is an especially serious problem in the northern Great Plains. In 1997, the Agricultural Research Service and the Animal and Plant Health Inspection Service of the U.S. Department of Agriculture (USDA), initiated a major Integrated Pest Management (IPM) research and demonstration project, TEAM Leafy Spurge (TLS), to develop and demonstrate ecologically based IPM strategies that can produce effective, affordable leafy spurge control. A key component of the project was to expand the use of biological control (biocontrol) agents, specifically flea beetles. To assess the level of insect establishment and the level of current and perceived... |

| An option to mitigating flood damages in the Red River Basin is the concept of using hundreds or thousands of ‘micro-basin’ storage areas comprised of roads and adjacent lands to retain a sufficient volume of water over a reasonable period in the spring to lower the flood crest heights on streams and rivers throughout the basin. This concept has been referred to as the Waffle. The present value of costs and benefits of implementing, maintaining, and operating the Waffle were estimated for a 50-year period. Costs included land enrollment expenses, landowner payments, infrastructure modifications and installations, and maintenance and administrative overhead. Data relating river crest heights with probability of flood occurrence and expected damages to... |

| Production agriculture in the 4-state area of southwestern North Dakota, southeastern Montana, northeastern Wyoming and northwestern South Dakota has faced serious economic challenges. In the mid-1990's, a growing number of recreational land buyers purchased land for wildlife habitat and hunting, rather than for farm derived income. A survey of the area was done to determine land ownership characteristics, information about land that was rented and leased out, and attitudes toward key issues facing landowners and farm and ranch operators. The average landowner owned 3,089.4 acres comprised mainly of pastureland/rangeland (2,242.6 acres) and cropland (473.3 acres). Ownership of farmland was primarily from purchases (70.6 percent) and inheritance (26.1... |

| Community hospital administrators in North Dakota were surveyed to determine the amount and type of expenditures made to North Dakota entities in 1997. Estimates of net revenues retained within the state were also solicited. Forty-two of the 44 community hospitals in the state responded. Economic activity from hospitals in the state was divided into two groups--community hospitals and all hospitals. In-state expenditures for Federal and Native American facilities were generated from survey results. Expenditures and returns (direct impacts) from community hospitals in the state were about $832 million in 1997. When the six military, Veteran, state, and tribal hospitals were included, industry-wide direct impacts increased to $904 million. Input-output... |

| Leafy spurge (Euphorbia esula L.), a widely established exotic, noxious, perennial weed, is a major threat to rangeland and wildland in the Upper Great Plains. Chemical, biological, and cultural control methods have limitations in their applicability and effectiveness in treating leafy spurge. However, many of the constraints prohibiting the use of herbicides, tillage, and biological controls do not apply to sheep grazing. Sheep grazing, while known to be effective in controlling leafy spurge since the 1930s, has lacked widespread adoption as a leafy spurge control. A deterministic, bioeconomic model, incorporating relationships between sheep grazing and leafy spurge control, grass recovery, and forage use by cattle, was developed to evaluate the... |

| Leafy spurge (Euphorbia esula L.), a widely established exotic, noxious, perennial weed, is a major threat to the viability of commercial grazing and beneficial outputs of wildlands in the Upper Great Plains. Herbicide treatments are often recommended based upon measures of physical control rather than on economic criteria. Considering the wide geographic variation of leafy spurge infestations, the range of herbicide control alternatives, and the long-term consequences this weed creates, a need exists to assess the economics of herbicide control. A deterministic, bioeconomic model was developed to evaluate the economic viability of current herbicide control strategies for leafy spurge. Only under liberal assumptions and optimistic projections does... |

| Barley is an important crop in the upper Great Plains, yet its economic importance has not been quantified. Expenditures and returns from crop production, grain handling, transportation, and processing activities represented the direct economic impacts from the barley industry. Secondary economic impacts were estimated using an input-output model. Barley production in the tri-state region averaged 3.3 million planted acres and 165 million bushels from 1994 through 1996. North Dakota had about 2.5 million acres. Barley production was estimated to generate $446 million in direct economic impacts. Total (direct and secondary) annual economic impacts from barley production were estimated at $1.2 billion. Annual direct impacts from handling barley at... |

| The purpose of this study was to estimate the economic contribution of crude oil and natural gas exploration, extraction, transportation, and processing in North Dakota in 2005. Primary data for the study came from three separate surveys of firms involved with various aspects of the petroleum industry. Exploration, the process of finding mineral resources, was estimated to have direct impacts (in-state expenditures) of $445.1 million. Extraction, the process of developing and recovering mineral resources, had direct impacts of $909.6 million. The processing sector of the industry, which included pipeline transportation of crude oil and natural gas, had $132 million in direct impacts. The North Dakota Input-Output Model was used to estimate the... |

| Agriculture remains a major component in the North Dakota economy, yet many activities within the agricultural industry remain unquantified. The purpose of this study was to measure the economic contribution of the soybean industry to the North Dakota economy. Expenditures and returns from soybean production, grain handling, and transportation were estimated to calculate the direct economic impacts from soybean activities. Secondary economic impacts were estimated using the North Dakota Input-Output Model. Since 1995, soybean acreage in the United States has increased substantially in nontraditional row-crop regions, such as those found in some parts of North Dakota. Soybean acreage in the state has increased 135 percent since 1995, and 210 percent... |
