The first snow came early, and it fell heavily, but it could not be held on the ground and melted quickly. But the forest was snow-white.

A group of macaques forage in the canopy of trees in the upper layer.

Several students stayed in a small tree hut on a tree to record the morphology and movement habits of each macaque.

Soon, however, the macaques scattered and fled. Because a huge eagle appeared in the sky.

This eagle is supposed to be the male of a pair on the other side of the Green Lake. This is a radius of hundreds of miles, and it is their sphere of influence. At first, people brought it from the north, but later it was too big, so it was mostly released.

It is believed by rangers to have an inhibitory effect on the activity of organisms in the upper canopy.

"What's wrong with this eagle's family, it's still out to hunt in such bad weather." A student holds up a telescope and watches the sound of sliding through the snow.

"What's wrong, it's just that you chose the wrong time to raise the eagle." Another student rubbed his frozen fingertips.

"Mr. Zhang, this snowy day also came out." When the student wanted to put down the binoculars, he saw Zhang Chun and his wife walking through the forest pasture.

"I'll see, I'll see." Several students ran over.

The student smiled and said, "You haven't seen it, it's already in the woods." ”

Zhang Chun came out because the Air Force had conducted an anti-aircraft missile experiment over this forest. The missile hit the target plane, and the target plane fell into the forest with a special fuel tank, burning violently#. The Air Force came up with the idea that the enemy could attack the forest with #incendiary bombs, causing forest fires. I was ready to put out the fire. Unexpectedly, the fire only burned at the site where the target plane crashed. The scope of the impact is not large. Finally, the target aircraft in the center was still blazing, and there was nothing going on in the forest not far away.

The burning branches that had been swept up by the fire fell to other places and were immediately extinguished. It is already autumn to ignite the forest that does not burn at all.

It turned out that the prepared firefighters were very curious. So a research group was set up to study what was going on.

Zhang Chun was also curious, so he followed a group of people into the forest.

"We think so, there aren't many combustibles in the forests here, and the same forests, such as the Great Khing'an Mountains, are not well maintained by humans. There are many fallen leaves on the ground and dead tree trunks in the forest. But you can't see it in a forest that is maintained by humans. The fallen leaves on the ground are deliberately turned into the soil by the rangers, and the animals are doing these things, so. There are a lot of fallen leaves, but you can't see much. ”

A ranger shovels through the soil overgrown with ferns and mosses with a small shovel, which is almost customary. The forest is littered with traces of their shoveling. The humus layer of the soil is very thick. A snake quickly swims away, and earthworms and various insects in the soil are also escaping.

Then there are the small pits that have been arched out by wild boars and other animals, and they are full of water. And the dense ferns cover them, if not the rangers who are extremely familiar with the forest. It was easy to win the bid.

A fresh big pit. Some of the rhizomes of lianas are exposed.

"This is the food of wild boars, it doesn't taste good, but the nutritional value is very good, some of the roots are very large, we will get it home to remove the crude fiber, and the starch in it is very good. You see, there's water in this pit. ”

A fox was disturbed and ran away as fast as it could. It threw a dead snake down. Ran to a short distance and saw that everyone was not interested in it, and actually came back again, and the dead snake took it away. The fox coat color this season is very beautiful. Niuniu tried to chase it, but Niuniu didn't take a few steps before she stopped, because she noticed a puddle not far from her feet.

She looked at the puddle, then at the fox that had disappeared.

The little mouth deflated, and he walked back cautiously. She had been fooled too much, soiled her clothes, fell, been bitten by disturbed insects, etc., and although she was not old enough to remember, the pain was remembered.

"These little puddles can breed mosquitoes. In reality, though, mosquitoes here can't get up because their larvae don't survive. Some small animals survive by eating them. Even if you survive. In front of us we can see a bat's nest, of course, we still have to apply some medicine to our clothes and bodies, otherwise we will still be bitten. However, we deduce that these are the reasons why the temperature that ignites the forest floor must be very high, otherwise it would not be possible. ”

Zhang Chun and Lizhi and Niu Niu, their bodies, mosquitoes can't avoid them. Entering the forest, the vast majority of people are curious.

In fact, it is very simple, two people use pollen and some drugs to stimulate them all year round, and use them to bathe, some of which are already highly toxic for ordinary people. But Zhang Chun and Lizhi are nothing, they have been like this for decades, and their bodies have long been used to it. At the same time, their blood can really poison mosquitoes. How could a mosquito go and bite two people.

As soon as Niuniu was born, she was able to take a medicinal bath with Zhang Chunli, and there was no discomfort at all.

Of course, if Niuniu disturbs centipedes and scorpions or the like, they will still bite Niuniu. Although Niuniu will not be a big deal, it is inevitable that she will cry in pain.

Zhang Chun and Lizhi use a wide range of drugs, and they will not cause imbalance in their bodies because of one or two. This is a lesson learned from previous experiences. This is also the reason why the two are used to running around. Because even regional plants and animals have limitations.

"Another reason is that there are hundreds of species of ferns growing here, and you see, some of them have dead leaves. But there is not much dead leaf on the ground as a whole. We don't see many dead trees and vines in this forest. Because they cut it down. And some vines die and decay very quickly. A researcher grinned at the ranger.

"A lot of the things you use are made from dead trees." The ranger laughed.

The researcher nodded, "So the forest needs care." If you don't take care of it, then nature will take care of it, which is the forest fire. Well-cared forests are very peculiar in some places. Look at these trees, their old dead bark, covered with moss, wet and slippery. There are also many living creatures. But in reality, the trunk is not affected. In unmanaged forests, termites and other things can grow because of the large number of dead branches. But in this forest, it is almost impossible to see. Because they don't have enough food, there are too many natural predators. Some monkeys eat them exclusively. ”

"It's such a cold weather, and you're still up there." The ranger shouted at the five or six students who were walking down the spiral ladder from the big tree.

The tree is more than a meter in diameter, but it seems to be very old and leafy. It is tens of meters high, because there are many vine plants climbing on the branches. So actually a little bit farther away you can't see the top.

I didn't see the students until I got closer.

"Hello Mr. Zhang, hello Brother He." The students greeted each other.

They were carrying equipment on their backs and covered in snowflakes. The snowflakes in the upper layers of the forest also fall down layer by layer because the leaves can't bear the weight.

"It's snowing so hard that it's going to rain for a day." The students warned.

The ranger said, "Got it." He turned back to Zhang Chun and said, "Mr. Zhang, let's hurry up." If the snow is really heavy, it will be quite troublesome. ”

In the distance, you can see the light in the clearing.

More than a dozen rangers are cutting down trees that have been burned to death. Some of the dead branches of the trees that did not die were also cut down. The cut wounds were coated with gum to prevent insect infestation. So although the fire did not spread, the rangers still cut down a large area.

The cut trees were divided into sections more than three meters long and stacked together. Even the smallest trunks are stacked in graded sections.

"Hello Mr. Zhang, I destroyed two good trees, and it has only been more than 100 years, and it has grown so thick. Can you please don't let them experiment here? Several rangers protested.

The target aircraft has been cleared by the troops. There was still a range of about a few tens of meters in the middle, which was charred and blackened. A large tree has a broken trunk burned. Two workers are sawing off the trunk of a burned tree with a large saw.

As the rangers said, the fire really affected only two large trees.

"The target didn't fall directly to the ground. Instead, he broke several branches and hung more than three meters of this big tree to burn, and burned the tree all the way down, burning all the trunks on the ground, and the oil from the exploding fuel tank splashed all around, and it burned like this. The researcher explained.

"Those who are soldiers lack morality, don't put out the fire, watch the fire burn, if you put out the fire, maybe this tree can be saved." The rangers who cut down the trees were very dissatisfied.

One of the military researchers who accompanied him was very embarrassed.

Because the fuel tank is not ordinary oil, one of the small fuel tanks is the burning # burn bomb. I was not prepared to save at all, and ordinary fire extinguishing equipment could not be extinguished. Half of the target machine burned out. There was still the smell of burning metal in the air.

Again, the experiment is to simulate the effects of being bombed. How is it possible to put out fires. (To be continued......)
