Information concerning lawn's growth, use, maintenance and the recuperative methods was collected from 93 selected parks. The results show that most of the lawns is damaged within one year after planted. This is because a more than reasonable number of people uses the lawns; the number of people visiting parks is especially over large in April and May when the lawn grasses are sprouting. Also, it can be said that an insufficient recuperative period and inappropriate maintenance and control measures may have caused damage to the lawn.
