Brief introduction of blue mountains national park

There are all kinds of eucalyptus trees growing on the mountain, green and blue everywhere. Eucalyptus is a long green tree with tall and straight trunk, hard wood and oil. It can extract volatile oil, and its volatile oil droplets are blue after being refracted by sunlight in the air, so it is named Blue Mountain. Blue mountains national park is formed by the accumulation of Triassic massive solid sandstone. It was once an obstacle for European immigrants to move westward at that time. 18 13 Brasland Lawson, a European, crossed the mountain to the inland and planted a memorial tree at the entrance of the mountain, which is still one of the pioneers' remains. The blue mountains have a pleasant climate and winding paths. There are 450-meter-high Three Sisters Peak, Keno Blue Cave, Wentworth Waterfall and birds pecking at rocks.

Eucalyptus plants in Australia have shown strong adaptability and evolutionary ability after leaving Gondwana, which has high cognitive research value. There are various typical environments suitable for the growth of eucalyptus leaves in the Blue Mountain area, including all kinds of dry and wet broad-leaved trees, small wilderness wasteland where Gali trees grow, and swamps, wetlands and grasslands unique to the Blue Mountain. There are 90 species of eucalyptus plants (all

13% of eucalyptus globulus leaves) and all four eucalyptus leaves. The blue mountain plants have strong regional characteristics, including 1 14 plants with Ming regional characteristics and 120 national rare and endangered plants. In the Blue Mountains, several evolved ancient legacy species have also been found, which are now very rare and can only be found in a small area.
