Once grassland productivity decreases, grass-renovation, accompanied by plowing and seeding, needs to be conducted to improve its productivity. Years after grass-renovation is one index indicating grassland productivity. In this study, the monitoring of grass-renovation status using satellite data is discussed. By extracting 1-year grassland and renovated grassland from each satellite image, we compiled a Grass-renovation years map (1985-1994) . Renovation years from satellite data agreed with that from ground survey with high accuracy, showing that satellite remote sensing is very useful for survey of grass-renovation status.
