Large-scale deforestation has always been the most opposed thing by the Ministry of Land, and for the first time in decades, this is the first time.
The Institute of Forestry and the Institute of Environment are very concerned about Dongshuiya, so they will gather some research institutes and students to visit every once in a while.
According to the general configuration of the management house, laboratories and guest houses are mandatory.
It's just that although Lizhi built a laboratory and a guest house according to the regulations, and provided them with electricity, she did not have any equipment.
The Information and Communications Bureau is getting communication fiber optic cables for Dongshuiya, and Zhang Chun has a set of satellite communication equipment himself, but it is all at a fixed time, and it is turned off after processing the documents quickly.
Therefore, Dongshuiya is still in a state of isolation from the outside world.
At the very least, there is no television communication system.
However, every once in a while, some books will be sent to the special container of Baiyungou Cave Shuiya, and most of the people who come to pick up the mail are cheerful Shui Ling.
Because Zhang Chun mobilized his collection of books in the fairy, Dark Moon and the Xinmin Foundation soon learned about Zhang Chun's whereabouts.
The National Land Institute, the Forestry College and some research departments in Songbai Town are also quietly changing.
This was known to Zhang Chun when the students of the Academy of Forestry came to intern for the first time, but fortunately, Dark Moon and the Foundation chose to keep a low profile and took the initiative to keep it secret for Zhang Chun, and the students who came to intern did not know that the couple was Zhang Weimin and Zhang Yuan whom they admired, so Zhang Chun acquiesced.
The College of Forestry took the initiative to provide the most basic laboratory equipment such as microscopy, laboratory testing, culture, analysis and so on.
Because the College of Forestry has received project approval from the Xinmin Foundation, the approved funding for the research on the original fir forest renewal project in Dongshuiya is three times the amount of the applied fund.
This equipment is part of the project's research.
How could Zhang Chun not know that this was a special arrangement by the Foundation.
Because the teacher who led the team was the son and daughter-in-law of Zhang Qiuyue, the director of the Environmental Research Institute, who was in his twenties, he grew up under the watch.
It's just that Zhang Chun has become low-key over the years, and the little ones are focused on studying and don't pay much attention.
Of course, this may be the reason why the two of them were transferred to Songbai Town.
Zhang Nanchang was born when Zhang Qiuyue was working in Nanchang, so he took such a name.
Guo Qiuyan's maternal grandmother was the daughter of a French priest and was half French.
His father was a professor of forestry at Dunhuang University and was half Russian.
The Western characteristics of this girl's face are still relatively obvious.
Therefore, it is also very bright.
Zhang Nanchang chased for a long time to catch up, and the two had a son who was more than two years old.
Zhang Qiuyue and her mother-in-law competed for their grandson, and in the end, Zhang Qiuyue only had one son, Zhang Nanchang.
And Guo Qiuyan has an older brother and a younger sister.
This baby son stayed in Xiangfan, and it was not easy for Zhang Nanchang and his family to meet.
Zhang Nanchang and his family are both people who are obsessed with research, and when they met Zhang Chun and his wife, they just said that you look very similar to Mr.
Zhang when he was young.
No more pursuits.
Zhang Chun and Lizhen know these two people too well.
Naturally, it will not be exposed.
Although there are only about 30 fir trees left in Dongshuiya, each one is a huge ancient tree.
After only one year of felling, the new branches and leaves have more than doubled.
So from a distance, in the clouds and mist, there is still a bit of primeval forest flavor.
After the felling of the forest, the forest rangers of the Forestry College and the surrounding management station transplanted a large number of tree species, which are of great variety, but after all, they are not as good as the original fir and red birch saplings.
Zhang Chun and Lizhi would take Shui Ling and them to inspect these mountains and forests in their jurisdiction every day.
Cut down some trees that pose a threat to transplanted species.
When Shui Ling and the others go out, they will also bring back some saplings.
It's just that the saplings they bring with them usually have some peculiarities.
These guys are much pickier than Zhang Chun and his wife.
According to Liz, they wouldn't want anything without spirituality.
When it comes to removing excess saplings, it's actually their perception that dominates.
This is more or less biased.
Therefore, Zhang Chun deliberately explained that not all species have spirituality, and not only spiritual things can be preserved.

Because ordinary species are the basis.
For example, chestnuts are delicious, oaks and acorns cannot be completely replaced, not to mention that there are too many varieties of chestnuts.
Food woody plants are important in forests, but non-food woody plants are equally important, as they can suppress forest pests and diseases and feed some of the forest's specialized species that also feed on these plants.
All plants, as long as they are used wisely, are medicines that can regulate the balance of the five elements in the human body.
How much to use and how to use it, if you carefully understand and perceive it, you will feel very wonderful.
Therefore, when managing forests, it is important to maintain maximum species diversity and not let your own knowledge be swayed, because your knowledge is always only a small part of nature.
"Forests, you can only do addition, not subtraction."
This is a principle that Zhang Chun admonished Shui Ling.
This made Zhang Nanchang and the students he brought with him constantly nod.
Zhang Nanchang and the others came over, and in addition to inspecting the existing secondary forest tree species, they also introduced mosses, ferns and lianas.
But it is mainly done around these ancient trees.
Small trees can't afford to toss vines.
"This is the disadvantage of pure fir forests, when one species becomes the dominant species, the space for other trees is squeezed out and eventually disappears into the forest system.
The forest system of Shennongjia is better, and as far west as the Qinling Mountains, and even in the northern forest areas such as the Great Xing'an Mountains and the Outer Xing'an Mountains, this kind of purified forest, and even the primeval forest, occupy a dominant position.
Until forest fires or pests and diseases destroy the original forest system.
This forest used to be a dying forest, and the pests and diseases that infested fir trees were proliferating in large numbers, and only 30 or so healthy trees were singled out for tens of thousands of fir trees. ” "Everyone has seen the building in Dongshuiya, it is made of fir wood, and it has been selected.
However, there are a lot of repaired wormholes on it, and although there is a lot of wood that is transported down, almost all of them need to go through complicated follow-up treatment before they can be used. ” "When pure tree species forests age and become less resilient, pests and diseases that feed on these species multiply, and trees begin to die and decay.
Whenever such a forest is struck by lightning, lightning fires occur.
It ended up being what it is now.
Manual updates just make this process more advanced. ” Zhang Nanchang looked up at the ancient tree and said: "But the evolutionary history has a huge inertia, after deforestation, some pests and diseases have not been eliminated because of this, because it has a seasonal and incubation period.
In the second half of 1941, these 36 ancient trees were crawling with diseases and insects.
At the same time, birds and some animals that used to feed on these pests and diseases are also concentrated here.
Once the balance between creatures is broken, they will try to re-establish the balance, but the process will be very intense.
Fortunately, we have strengthened the protection of these ancient trees during this period.
Because of the human factor, these ancient trees have survived the most difficult period. ” Zhang Nanchang pointed to the vines and bryophytes that had just been planted: "The introduction of these species is to shorten the time to rebuild the balance of the biological chain.
When new food chains begin to crowd out the space of old ones, old ones that have broken down rapidly shrink. until a new equilibrium is reached.
Of course, this also requires these ancient trees to have good vitality and healing ability.
Otherwise, you can't resist it. ” "Teacher, that is to say, these ancient trees were still damaged during this period, but because they still retained their self-healing ability, they were stocked."
"Yes, not only last year, but also in the future.
It's just that they haven't exceeded their defensive limits.
When trees encounter pests and diseases, in addition to relying on the biological chain to contain and reduce pests and diseases, they also have the ability to protect themselves, such as being able to secrete toxic hormones to kill pests and diseases, and can quickly fill the wormhole with new tissue.
We can clearly see the residual scars on the growth rings and textures of some trees.
However, it depends on whether these ancient trees still have this ability.
You must know that decaying wood has no protective ability, because the circulation structure in the body is interrupted, not only can not kill pests and diseases, but these rotten parts will also become a stronghold of pests and diseases.
So when we pick and choose to keep these trees, the least amount of decay is the most important indicator. ” Zhang Nanchang said with a smile: "Actually, these trees are so old, there must be decaying parts, but there are relatively few of them."
It took us months to remove the rotten wood and do a lot of insect control to rejuvenate the trees. ” Shui Ling smacked her tongue in a low voice: "It's so complicated." ” Zhang Chun smiled: "Now you know, to protect these forests, the forest rangers are just guardians, but how to maintain the vitality of the forest, how to increase the output of the forest, how to renew the forest, including the decisive introduction of species, is not up to you, they are to do."
You have been trained since childhood, so you read less books, and later read more systems theory and cybernetics.
To do anything, you have to think a few more steps forward. ”
