Three species of plants are endangered

According to the research of scientists, the earth has existed and operated for billions of years, the internal biological chain has matured and stabilized, and endangered plants are also a link in the entire biological chain.

To put it simply: to protect endangered plants is to protect ourselves!

2.Endangered plants are closely related to our daily lives:

Many aspects of our lives are closely related to plants, in addition to food, clothing, housing and transportation, there are herbs will ** our health, plants purify the air and make us feel comfortable, etc.;

I think that endangered plants are also members of the plant kingdom, and their existence is reasonable, and if endangered plants become extinct in large numbers, it will definitely affect the balance of nature, and it is us humans who will suffer in the end!

In recent years, the earth has been severely damaged by human beings, causing a large number of animals and plants to become extinct one after another. Honai cycads, naked ferns, reed wood, seal wood, pith wood...Thousands of plants have been wiped out, and more than 40 of China's 35,784 plant species have become extinct (conservative data).

In some places, plants are cut down and used as firewood for cooking; There are also people who pick plants with medicinal properties to heal or nourish wounds; Some people have even developed wetlands with rare plants to build buildings...

Some people may ask: what are the benefits of plants for humans? Why do humans want to protect these plants?

Personally, I think the main reasons are as follows:

In recent years, countries around the world have realized the importance and rarity of plants, and have included some frequently threatened plants in the plant protection list. The first-class protected plants in China are: Metasequoia, Dove tree, Alder, Golden Flower Tea, Ginseng, Bald Fir, Wangtian Tree, Silver Fir...

For the sake of biological diversity and ecological balance and symbiosis!

The diversity of species is conducive to the stability of the ecosphere!

The rare plants with less than 10 plants in China are:

Putuo hornbeam has 1 extant plant. It is a deciduous tree of the birch family, an endangered species, a national first-class protected plant, and an endemic species in China. In the 50s of the 20th century, there were still a few trees in Putuo Mountain, and they were destroyed due to reclamation and other reasons.

There are only 2 leguminous deciduous trees, endangered species, and national second-class protected plants. Honey locust fluffy is named because the pod is densely covered with yellow-green fluff, and the flowers are heterogeneous and the fruit is very rare. According to the literature, honey locust can be used as rootstock for grafting and propagation, but the technical requirements are very high and it is not easy to master.

There are only 3 deciduous trees of the Sycamore family, an endangered species, and a national second-class protected plant, which is endemic to China. The wood grain is straight, the material is flexible and easy to process, and it does not crack, which is the best material for making furniture, construction, and plywood. The flowers are first and then the leaves, and the flower color is bright and beautiful.

It has a high ornamental value and is a good product for landscaping and street trees.

There are only 3 remaining Pinaceae evergreen trees, endangered species, national first-class protected plants, and endemic species in China. Baishanzu fir is a unique ancient relict plant in China, and it is also the only remaining fir plant in the southeast coast of China. In 1987, the International Commission for the Conservation of Species declared Fir as one of the 12 most seriously threatened species in the world.

There are only 4 remaining deciduous trees of the Acer family, an endangered species, a national second-class protected plant, and an endemic species in China. It is closely related to Acer japonica produced in Hokkaido, Japan, and is an ancient remnant species with important scientific value.

There are only 5 deciduous trees of the birch family, an endangered species, a national first-class protected plant, and an endemic species in China. Because the habitat is owned by the local rural collective, the habitat is frequently disturbed by humans and is in danger.

There are only 6 remaining magnolia evergreen trees, rare species, and national first-class protected plants. Although the flowering and fruiting are normal, there are few mature seeds per fruit, and there are no seedlings around the native mother tree, and the natural regeneration ability is very low.

There are only 6 evergreen trees in the linden family, which is an endangered species and a national second-class protected plant. It is endemic to southwest China and one of the main tree species of the oligogene, which is of great value in the study of flora geography and the application of breeding precious tree species.

There are only 10 semi-evergreen trees of the Euonymus family, which is an endangered species and a national first-class protected plant. This is the only one of its kind in our country. The knee handle found in the southwestern part of Guangxi is the northernmost species of this genus.

It has important scientific value for the study of seed flora geography and tropical relatives in China.

Nowadays, it is only distributed in Guizhou, Sichuan, Guangdong and other places in China, and is a rare and endangered protected plant in China.

and northern Myanmar, but rare and rare.

The world's best wood species for ships and vehicles are exclusively produced in Xishuangbanna, China.

Primeval forests.

More than 300 species of plants from 76 families, including Chinese pigeon tree, dove tree, big tree rhododendron, wild lychee, metasequoia, and Wangtian tree, are endangered.

Plants are one of the main forms of life and include familiar organisms such as trees, shrubs, vines, grasses, ferns and green algae. Plants such as seed plants, bryophytes, ferns and ferns are estimated to have about 350,000 species in existence. Until 2004, 287655 species had been identified, with 258,650 species of flowering plants and 15,000 species of bryophytes.

Most of the energy for green plants is obtained from sunlight through photosynthesis.
