Brucellosis is a nationally and internationally regulated disease of livestock with significant consequences for animal health, public health, and international trade. In cattle, the primary cause of brucellosis is Brucella abortus, a zoonotic bacterial pathogen that also affects wildlife, including bison and elk. As a result of the Brucellosis Eradication Program that began in 1934, most of the country is now free of bovine brucellosis. The Greater Yellowstone Area (GYA), where brucellosis is endemic in bison and elk, is the last known B. abortus reservoir in the United States. The GYA is home to more than 5,500 bison that are the genetic descendants of the original free-ranging bison herds that survived in the early 1900s, and home to more than 125,000 elk whose habitats are managed through interagency efforts, including the National Elk Refuge and 22 supplemental winter feedgrounds maintained in Wyoming. In 1998 the National Research Council (NRC) issued a report, Brucellosis in the Greater Yellowstone Area, that reviewed the scientific knowledge regarding B. abortus transmission among wildlifeâ€"particularly bison and elkâ€"and cattle in the GYA. Since the release of the 1998 report, brucellosis has re-emerged in domestic cattle and bison herds in that area. Given the scientific and technological advances in two decades since that first report, Revisiting Brucellosis in the Greater Yellowstone Area explores the factors associated with the increased transmission of brucellosis from wildlife to livestock, the recent apparent expansion of brucellosis in non-feedground elk, and the desire to have science inform the course of any future actions in addressing brucellosis in the GYA.

Brucellosis, a bacterial disease, was first noted in the Greater Yellowstone Area in 1917 and has been a chronic presence there since then. This book reviews existing scientific knowledge regarding brucellosis transmission among wildlife, particularly bison, elk, and cattle, in the Greater Yellowstone Area. It examines the mechanisms of transmission, risk of infection, and vaccination strategies. The book also assesses the actual infection rate among bison and elk and describes what is known about the prevalence of Brucella abortus among other wildlife.

Elk (Cervus elaphus) and bison (Bison bison) of the Greater Yellowstone area are the last known reservoir of bovine brucellosis (Brucella abortus) in the United States. domestic cattle occasionally contract the disease while grazing in areas where infected wild ungulates have aborted their fetuses or have given birth. Cases of brucellosis in cattle trigger costly quarantine, testing, and culling procedures. Government agencies and stakeholders, therefore, allocate valuable resources to prevent wildlife-to-cattle transmission. Scientific uncertainty about the biology, epidemiology, and economics of brucellosis makes it difficult to determine the length to which society should go to control it or the combination of management activities they should use to achieve the desired level of control. Research over the last decade has generated new information about brucellosis and alternative approaches for management. Stakeholders and decision makers must syhnthesize this growing body of information and re-assess current brucellosis goals and management strategies. Economic principles provide an objective framework in which to do this.

Brucellosis eradication in livestock has been a long and arduous process, but it appears the 1998 target date set by the State-Federal Cooperative Brucellosis Eradication Program may be well within reach. This effort, which began over 50 years ago, has made dramatic strides. During the 1950's, approximately 124,000 cattle herds were under quarantine because of brucellosis. The number of quarantined herds dropped below 1,000 by 1990 and fell below 100 in 1995 (Burgess, Russell, USDA/APHIS, personal communication, August 1995). Now that the livestock eradication program is nearing completion, more attention is being placed upon brucellosis in wildlife because of possible wildlife and livestock interactions. This focus is presently located in the Greater Yellowstone Area. The Greater Yellowstone Area consists of Yellowstone National Park and the surrounding area in Idaho, Montana and Wyoming. Because bison and elk, principal carriers of brucellosis in wildlife, are an enduring symbol of the pristine environment in the Greater Yellowstone Area, anxiety is mounting concerning possible repercussions any solution may have upon wildlife.

Conflicts between wildlife and cattle in western Wyoming probably began to occur when the first agricultural settlers arrived in Jackson Hole in 1884. At that time, many traditional winter ranges of elk (Cervus elaphus nelsoni) were converted to hay fields for cattle feed during winter or to town sites, such as Jackson. In somecases, elk migration routes to historic winter ranges were blocked by a multitude of fences, roadways, communities, ranches and hunters. In 1910, the situation became so acute in Jackson Hole that the Wyoming Legislature appropriated $5,000 to feed elk near Jackson. This was done in response to complaints about hungry elk consuming hay stored for cattle feed and in anticipation of excessive elk deaths due to winter starvation. In 1912, federal legislation created the National Elk Refuge, and winter feeding of elk on an artificial diet of hay was well on its way to becoming a poor substitute for native winter ranges and incomplete resolution of ek and cattle conflicts (Boyce 1989). Marked changes also were occurring within and on the fringes of the rest of the vast wilderness area occupying parts of Wyoming, Montana and Idaho that is now known as the Greater Yellowstone Area (GYA). In fact, Congress had already (1872) designated Yellowstone National Park as the nation's first National Park in order to protect the numerous and unique natural wonders of the area, including wildlife. Congress also designated much of the land adjacent to Yellowstone as the first National Forest Preserve. Simultaneously, cattle grazing was becoming one of the regions important economic mainstays (Keiter 1991).
