     "text": "The wild horses that roam the west are feral descendents of domestic animals that either escaped from or were intentionally released by early European explorers and later settlers. As a result of both origin and contemporary management, the Spanish or Iberian influence remains strong in some wild horse populations (e.g., the Kiger, Pryor Mountain, and Sulfur Mountain herds). In other populations, escaped or released military, saddle, and draft horses dominated by the Thoroughbred, Morgan, Quarter Horse, and draft breeds have formed broad zones of introgression (intermixing), sometimes with Spanish bloodlines. These populations of mixed ancestry increased to inhabit large areas of the western U.S."

Information on the horse and field observations are then added to the horse's record in the Wild Horse Database. Then, to ensure that information is added to the correct horse\u2019s history, managers must review previous descriptions and photographs of the horse's markings. Managers can use the Application Database to retrieve information on individual horses as well as generate various reports. With a database of photos on the color and markings of individual horses, it is a simple matter to quickly identify horses for various purposes, including familiarizing new or volunteer staff with particular individuals and herds."

The U.S. Geological Survey (USGS) is the research arm of the Department of the Interior (DOI), and in 2000 the Fort Collins Science Center hosted a series of expert panels to discuss the subjects of fertility control, population estimation, herd genetics, habitat assessments, and health and handling issues. Based on reports produced by these expert panels and information from a variety of other sources, BLM, FORT, and U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) staff prepared a Strategic Research Plan for wild horse and burro management. The priority for management initially focused on fertility control and population estimation."
