Meat prices going up & wolf kill. Once they were extirpated, the rest of the food chain below them collapsed. By protecting livestock through preventative measures, such as physical barriers and migration mapping, and reaching out to farmers about how to use these and other methods to better manage and protect their herds, it will be possible to prevent livestock losses while maintaining a natural balance in the Yellowstone National Park ecosystem. .Volpi, G.

With the tremendous development of technology in the time since the wolves were reintroduced, there are various options to monitor the population of wolves. The extirpation of wolves from YNP in the early 1900s led to a trophic cascade that negatively influenced many other species and populations of lower trophic levels within the Greater Yellowstone Area, both through lethal and nonlethal effects (Ripple and Beschta 2003; Ripple and Beschta 2012).
