Andrew P. Dobson, a professor of ecology and epidemiology at Princeton who has studied diseases near Yellowstone, said that the feed grounds have been a problem for the last 30 years although there is no palatable way. The one thing that may save Yellowstone from an outbreak of chronic wasting disease, Dr. Dobson said, is the wolf, which was re-introduced there in 1994. Dr. Dobson cautions that it is important to keep in mind the critical role of disease in natural systems and points out that half of all species are parasites and pathogens.
