Quercus miyagii
Fagaceae
- Range
- Endemic to the Ryukyu Islands(Amami-Oshima, Tokunoshima, Okinoerabu-jima, Okinawa Island, Kume-jima, Ishigaki-jima, and Iriomote Island)
In the diorama, a towering tree can be observed along the valley.
This tree is endemic to the Ryukyu Islands, ranging from Amami-Oshima to Iriomote Island. It typically grows along valleys in mountainous areas and can reach heights of 20 m, with trunks over 1 m across. Mature trees often develop wide, plank-like buttress roots that help support them. In autumn, it produces what are known as "Japan's largest acorns," about 2.5 cm in diameter. However, the number of acorns fluctuates greatly from year to year, and in many years, only a few can be found. On Tokunoshima, you can explore a forest of this species along the Matsubara trail on Mt. Amagidake.
Habitat of This Animal:
A:Forest along the valley - A3:Deep forest
Along the mountain valleys grows a high humidity forest. In such an environment, Quercus miyagii, a species of oak often grows in clusters. Some of these grow more than 20m tall and with trunk diameters exceeding 1m, with largely developed buttress roots. Also, there are many animals and plants preferring humid environments, supporting the abundant biota of Tokunoshima Island together with the forest along mountain ridges.
