This report examines trends in the varieties and numbers of shrubs and trees planted each year in parks in Tokyo Metropolis, and covers 100 parks opened up to 1977, 103 parks opened in 1990, 160 parks opened in 1995 and 1996, and 83 parks opened in 2000 and 2001. This study found that, up to 1977, fast-growing trees were selected as a pollution-reduction measure; in 1990 there was a rapid increase in flowering trees - such as cucumber trees and dogwood - and plants that provide soil cover, in 1995 and 1996 there was a shift to a wider variety of seasonal nursery trees and plants, flowers and fruits. Such trends continued in 2000 and 2001, but the number of varieties was greatly reduced to cut costs, reflecting the worsening economic situation.
