Lived to be 4800 years old! The longest-lived bristlecone pine on earth is dying, or it may not survive the high temperature next summer
According to the Guinness Book of World Longevity Records, the world's longest-lived person is Ali Mihan Seyiti from Xinjiang, China, who lived 134 years old. Is it an enviable longevity, but it is not worth mentioning compared to the lifespan of some animals. In 2006, scientists discovered a deep-sea round clam in Icelandic waters that lived to be 507 years old. There are many animals in the world that can live to be hundreds of years old. Bowhead whales can live to 300 years old, Aleutian scorpionfish can live to more than 200 years old, and turtles can live to 180 years old. It's just insignificant, many trees can live for a thousand years at random. In the alpine jungles of Colorado, Arizona, and New Mexico in the western United States, there are a variety of evergreen trees growing throughout the year, many of which are more than a thousand years old. Among them, a bristlecone pine lived for 4,853 years and was called by people. It is the "Methuselah" of the tree world, the longest-lived tree in the world. The name "Methuselah" appears in the "Bible" and is the name of a person. The "Bible" says that Methuselah lived 969 years. If this is true, he is the oldest person in the world, Now people give the name "Methuselah" to the world's longest-lived bristlecone pine. In the long years of 4853 years, it is believed that "Methuselah" has experienced countless ups and downs, and must have suffered from severe weather such as cold waves, heavy rains, strong winds and extreme droughts, but "Methuselah" is extremely vigorous, and all As soon as it came through, it stood up until 2022. But this year, "Methuselah", who has lived for 4,853 years, faces an unprecedented threat and is likely to die soon, struggling to survive the drought this summer, or the high temperature next summer. Pinus longaeva belongs to the evergreen tree of the Pinus family, with a height of less than 15 meters, but the trunk diameter can reach two meters, it looks thick, the color of the bark is orange, and the yellow-green needles are about 4 cm long. 5 needles, with bright white pores on the surface, the needles can stay green for decades. It is the longest-lived tree in the world, 150 years for willows, 300 years for pears, 400 years for jujube trees, and 1200 years for pine trees, but the lifespan of pine trees is 5,000 years. Years of history, but a custard pine can witness the history of our country. What made "Methuselah" so long? There are 4 reasons. The bristlecone pine has a special function, like some animals hibernate, when the external environment becomes very bad, such as dry weather for several consecutive days, the bristlecone pine stops metabolism and enters a dormant state, and the bristlecone pine will not resume until the external environment improves. Come back to life. The growth rate of bristlecone pine is extremely slow. The place where the bristlecone pine grows is covered with dolomite. Dolomite contains only a few nutrients. The rocks are wind-eroded into infertile soil, which is limited by sunlight and nutrients. The growth rate is extremely slow, only 2.5 cm tall every 100 years. There are no other trees that compete with it for nutrients. The environment where the bristlecone pine grows is arid and barren, and there are so many stones. It is difficult for other trees to survive in this environment for a long time. There are basically no other trees in the place where the bristlecone pine grows, and no other tree can compete with it. nutrition, there is no existential threat. It has strong resistance to insect pests. The conch pine tree is rich in pine oil. Pine oil can wrap small animals in it to form amber. Pine oil is a very viscous substance. Therefore, pine oil has become an effective weapon to prevent the erosion of germs and pests. But now, "Methuselah" is under unprecedented threat, which is related to the extreme weather in recent years. Affected by extreme high temperature and drought, the global warming will further intensify in 2022, and the global climate will become very abnormal. Some areas will become dry and less rainy, and some areas will experience extremely severe floods. The Americas, Europe and Asia have experienced decades. Unprecedented hot and dry weather. Although "Methuselah" has a strong ability to resist drought and can even enter a state of sleep, the continuous months of high temperature and drought have evaporated the last water in "Methuselah"'s body, which has exceeded "Methuselah". tolerable limit. Insect Invasion, American ecologist Constance Miller discovered an insect that was eroding the bristlecone pine when he inspected it. Drought has reduced the pine oil content of these ancient bristlecone pines, resulting in less resistance to pests. As a result, this insect rips open the bark and eats away at the tree tissue, resulting in many long holes, which pose a great threat to the survival of the brix pine tree. Hundreds of brix pine trees have been eroded by insect pests. Also in it. Now, "Methuselah" is in very bad condition, being affected by heat and drought, and being severely eroded by insect pests. "Methuselah" is about to die. It has survived the drought in 2022 with difficulty, but it may survive the drought next summer. This ancient tree that has lived for more than 4,800 years will soon come to an end.
