Not long ago, we drive to Chicago. The plains of the traditional Agricultural Agriculture in the United States, slowly brushed around. In the feeling, it is always not right. Suddenly awake, it is because of the vast winter wilderness, the southern "of the southern" is already alternative to the endless farmland. A messing grove becled a big blank embellishment. I think this is what "people" doing things on the earth. The survival of people is constantly changing this earth's face, but they are considered by us.
We came to the southeastern part of the United States, like a major reason here, is the boundless forest. The mystery of the forest has always made me fans. We have also lived in a northern forest area in China, but there is excessive deforestation, which has already made a big tree that exceeded "a hug". Every winter, you should cut wood to warmer, you can't find the like "of" 出 柴 "in a nearby, the way to cut wood, must be more distant in the mountains a year. The forest falls, the dense shrubs stand up. The mountains of the just have become weak. It turned out that Herch's name is the name of the mountain, thinking that he finally approached the forest. I didn't expect that the forest was back, and the speed of retreat even exceeded us to take the footsteps. The forest turned into a dream, and it seems to touch its edge, but it can't see its face.
More than a year of the forest dreams are rounded here. There is pine cypress here, but it is based on deciduous trees. There are all kinds of maple, as well as ginkgo, goose, sweet rubber, eucalyptus, 柞 tree and birch and so on. Now there are now, they appear in front of them and the four-season color. They have all the good characteristics of life, affinity, peace and idle, there is an immersion, not for you. Here, countless ginseng big trees are rolled out in the sky, the summer is dense, rich in autumn, the winter is lanzy, in the spring of spring, will surprising a tree tree flowers. Especially if it is old oak, like a life, it is also an old man you can always talk. The four seasons of the forest will bring us a wide range of visuals, more in invisible, balanced emotions, enlightenment, and soothing. Become a strange communication between people and unknown gods. We will celebrate that he can choose Lin, and it is often a celebration to himself: Fortunately, the most natural landscape has not encountered a lot of people.
However, I will soon discover that we are still wrong. Only one hundred years ago, the scene of the eastern United States is another kind of thing.
It turned out that we did not see the most beautiful forest landscape in the eastern United States. I don't know when to start from ancient ancients, until 100 years ago, the East Coast of the United States, from the south of Maine (MAINE), to the southernmost Florida (Piedmont, East), West to Ohio The valley (Ohio Valley) has grown than the old oak trees we saw today.
North America is a migrant land. The immigrant pioneers came here, and the chestnut tree was naturally honored as "tree king." There are hundreds of years old chestnuts in the mountains. Call it as a king, maybe the first is because of it. The height of the American chestnut tree is more than 100 feet. Now there is a lot of chestnut samples, there is a diameter of eight feet to ten feet. Several people can't hold it, and there is more than the phase. Not only big, chestnut is still the most important variety in the east of the east. Almost every four deciduous trees, there is a chestnut tree. It is said that squirrels only need to jump on the branches of Chesty, you can easily jump from Georgia in the south to New York, and the paws do not need to be stained. In the most famous Abarachi Mountains in the eastern United States, many hills are whole chestnut forest. The evening wind in the early summer has blown, and the mountain people are in the river's canoe, they are full of fallen chestnut flowers, look back, the whole mountain is like snow, and the white flowers are covered with milky. All this, for our neighbors Jamie, just that he also saw the scene seen by him. For new mainland immigrants, the American chestnut tree also offers the most basic guarantees of winter - chestnuts, just for thousands of birds, squirrels, until the deer and bear are generous. Chestnuts is still a major cash source in many Padlachi mountain poor families. In the harvest season, fresh chestnuts from there, riffed chestnuts, filled with small stalls on the streets of big cities. Gradually, the people here also began to cut down the chestnut tree because chestnuts can provide them with good hardwood. Chestnuts have a long history, all over the panel, but the variety is different, and the American chestnut tree has its very unique place. Its texture is excellent, as well as the famous mahogany in North America. Moreover, the trunk of the American chestnut tree straight straight, from the ground, can have a whole fifty feet. Therefore, people not only do not do furniture, but also build a house, even as a railway pillow. Take the tree, which is of course the same thing that eats chestnuts will not go to the undensive thing. However, because the beauty of the beauty of the beauty, the number of immigrants in North America is still not much, so their deforestation is far from achieving the surface of the forest.
However, not only the demand for human survival will change the natural landform, but the flow of people will lead to mutations in nature. A few years ago, I have written an article, which is a story of international fairs in the United States, how to make a story from Japan's vines in the United States. Although, it can also be called a staged plant disaster caused by human communication, but I don't know how, the story listened to the total struggling comedy. Now the story of this American chestnut tree is completely a tragedy.
Dafan immigrants have the same experience: the hard work, after the warmth, the feelings of homesickness will be born. What they think will be some very specific. For example, a cans of special pickled pickles, a glass of special fragrant green tea, a mother species on the fruit tree of the backyard. In this way, they began to find such an emotional condolences, and they moved to their new home. So, immigrants are not only people's migration, but the species began to transcend their own communication skills and began to float the Ocean between the continents. Not only immigrants, that is, people's cross-border travel and interaction also bring such species exchange, China's tomatoes and potatoes are like this. The prefix of the tomatoes refers to its "Western" from overseas, and the potatoes are known as "foreign" humei in the south. This "foreign" is "Ocean".
Immigrants in North America are no exception. Here, there is a tree called "Shassa Fyeisha", we just attracted it. It grows very high, spring flowers, autumn with chic bright yellow. Friend Sena has specially traveled in the small sapling that people discarded during the land, gave us a tree root. Its root is large, there is a strange fragrance. This is why it comes from distant Europe to North America. Because the French is accustomed to the roots of Shasa Fletchas. The French immigrants are tirelessly transplanting this seedlings in North America to treat their homesickness. Shasa Freesha is particularly non-transplanted, we have tried to transplant several small seedlings from the neighbors to their own yards, using all the way, and repeatedly do not become. I can imagine that the French immigrants of North America have tried again and again, and the toughness of "plant healing" is a toughness of "plant healing". So, Asian chestnut trees also involved in the Ocean and entered the Americas.
One hundred years ago, a big disaster caused by species exchanges finally broke out in eastern United States. The disaster occurred in the "Tree". In 1904, in New York City, the Bronx Zoo, people were surprised to find that a huge casino tree began to wither. More unfortunately, this is not an isolated incident. Soon, the chestnut tree in the eastern United States started witherping and dead. Plant pathologists quickly discovered that this is a molded bacteria carried by the chestnut tree transplanted in Asia, and Asian Chesty Tree has strong disease resistance to this mold, and the American chestnut is no resistance. The scientists at that time did not have any way to curb the diffusion of this mold. People looked at a giant wooden disease, watching their green leaves began to lose gloss, then curled, fallen. The green juice of life begins with the tip of the branches. From the beginning of the onset of the first tree, only a short period of decades, to the 1950s, the main varieties of the nine million acres of forests in the eastern United States - Americas, have been in fact all extinct . The huge chestnut tree is still standing, but it is already a lifeless statue, they stand, it seems to be just warned to humans.
After forty years, we came here, the American chestnut trees in the eastern United States have not traces, just like a history of testimony, being erased. When we launched the spectacular of the forest, we didn't know that the US Eastern Forest in front of the eyes, in fact, it has shrunk due to the disappearance of the beautiful chestnut tree. There is still a small amount of chestnut tree here, which is the Asian chestnut tree, but the branch is low, the trunk is not so straight, and the tree is much smaller. For more than a hundred years, American scientists have been dreaming of restoring the original forest landscapes in eastern United States, and seeking to cultivate the way to prevent mymae, including hybridization, and more. In 1983, the American Chesty Foundation was established. Fund will raise funds and take the way of cooperative research. However, all these efforts have not been satisfactory in a long time. Until the development of genetic science is applied to this research area, people have achieved breakthrough progress. They know today, where the previous research is wrong, but more importantly, they finally know, what is the way to solve the problem, know what they do have power, re-look back. However, not only the funds are required, but it takes time.
The Joy Tree Foundation has received a large number of scientific research institutions and also got a donation of a large number of people because they have the same dream. Recently, I lived in Mary, Pennsylvania, Anna, European, donated the 82-acre land to the Foundation, as an experimental planting base for the American chestnut tree. This land is located in the heart of the Turkish forest. Mary listens to the beautiful chestnut forest from the child. Now, she donates the land left by the parents, as an experimental base to restore ancient chestnuts. She feels that she can't think of a better way to commemorate my father and mother who is with the dream of the chestnut tree. Natural ecology is destroyed, often a matter of mankind, but it is necessary to recover, but it is so tough. After a large species disappeared, even never recovered. American scientists said that even if we cultivate the beauty of the American chestnut tree, even if today, we can plant the same amount of saplings, to restore the east forest landscape of the year, still take a few hundred years.
Our neighbors, 78-year-old Jiemei said, once to cultivate the anti-illness of the American chestnut tree, he must immediately buy a place in his own yard. Although he could not see the replacement of the chestnut forest, it would be seen.
I said: Yeah, we also have one.
