GIS Analysis of Grazing Selection by Goats in Tov Province, Mongolia
摘要
In Mongolia, the rapid grassland degradation induced by overgrazing in these years is assumed to worsen the disaster called dzud. In this study, we attempted to monitor the grazing behavior of flock of goats in connection with the vegetative and topographic environments in Mongolian grassland. From the results of the GIS analysis, goats’ movement in the grazing situation is found out to be less than the velocity of 4 km h and the mode value to be ca. 0.4 km h. Slight correlation (r=0.67) of the grazing velocity with NDVI value was found.
