Developers originally planned to cut down 743 of the 1,904 existing trees 3 meters or taller and transplant 275 others while newly planting 837 trees, according to Mitsui Fudosan. Under the revised plan announced Sept. 9, the number of trees to be cut down has been reduced by 124, including 66 that will be maintained where they stand and others to be transplanted elsewhere within the area. As additional new trees will be planted, the number of tall trees will increase to 2,304 after the redevelopment, according to the revised plan. The Gaien district, a haven for office workers and others throughout the year, is famed for its four rows of 146 ginkgo trees about 30 meters high, which date from 1923. There were concerns that the relocated ballpark, which will stand along the ginkgo-lined street, will adversely affect their growth. Developers said they will expand the distance from the ballpark to about 18.3 meters, from the originally planned 8 meters, to better protect the roots of the ginkgo trees.
