Because the purpose of the garden is to display all kinds of plant life, and it has been operated for almost 100 years, the trees are tall and vigorous, the floor beneath the trees is damp and dark, and people are prohibited from walking in certain areas. Added to all this, there is a rippling pond. This is the equivalent to manufacturing an optimal environment for living things.
由於植物園的目的就是展示多樣的植被，且經營已近百年，樹高葉茂，林地上潮濕、蔭蔽，又限制人們進出踐踏，加上一座水漾漾的荷花池，等於製造了一個生物最好的棲息場所。
