context_page_description: The biota of Tokyo Imperial Palace grounds, especially of the Fukiage Garden, consists of enriched and distinct flora and fauna found in Tokyo, Japan. An untouched, vast open space in the middle of Tokyo hosts diverse species of wildlife which have been catalogued in field research. For comparison, this article also covers biodiversity in other open spaces in the central districts of Tokyo.
context_section_description: There are three noted species of trees of the Palace. One is a fir tree (Abies) in the Three Palace Sanctuaries. In the Meiji era, other trees of the same species were  more than several hundreds in number, but only 8 trees survived in 2001. This one grew to a large size.

  The second is Liquidambar formosana Hance (English name: sweet gum) (Japanese name: fū), which was transplanted from China in 1727 by Tokugawa Yoshimune. Originally L. formosana was planted where Chinese emperors lived. There were 13 tall trees in the Fukiage Garden; the tallest was about 20 metres (66 ft) high, and 5.1 metres (17 ft) in circumference, but whether they were introduced in 1727 was not verified.  The crowns of this tree turn reddish-orange or crimson red in fall.
  The third is Metasequoia glyptostroboides, the dawn redwood. A young plant and 500 seeds were presented to Japan by an American scholar in 1949. The young plant and one from a seed were planted in the south of Kaentei House of the Fukiage Garden. Both were 27 metres (89 ft) high and one was 2.7 metres (8 ft 10 in) and the other 4.1 metres (13 ft) in breast-height circumference in 2001.
