Abstract
Based on a large number of samples for veterinary and ecological studies collected by population control in Gifu and Nagano Prefectures since 1979, there has been a remarkable advance in understanding the biology of Japanese serow owing to the efforts of many researchers. However, the knowledge and techniques obtained through these studies were not always used efficiently to practical management of the serow populations. We need a stronger biological criterion for management in conservation of the populations. We have developed a computer simulation model to estimate minimum viable population(MVP) size of the serow based on the population dynamics caused by a mortality due to the parapoxvirus infection. The role of wildlife veterinary researchers is to collect more accurate data which are needed for a simulation.
