With the transportation and horses these days, Feng Lanchu has been exploring the pasture outside.

And Wang Bingbing has also been conducting research in the hardest-hit areas of Caochang. Among them, how to abuse the little assistants can write a 30,000-word essay with eloquence, so I won’t repeat it here. In short, most of it is tears.

After three days of investigation, Feng Lanchu and Wang Bingbing did not go out on the fourth day but met to discuss the research and conclusions of the past few days.

The two were sitting in the office, both holding notebooks and a thick stack of documents.

Wang Bingbing first started his work description. He's been checking grass samples for the past few days. From the analysis of the grass stems to the soil layer, the results obtained are all within the normal range, and there are no problems with diseases and insect pests.

"I think the most serious problem in this pasture is trampling, just like the place where you often walk, there is no grass, and this is also the case in this pasture. So, in theory, as long as this piece of land is left unused, it will soon be Can re-grow grass."

"But how fast this is, well, I can't guarantee it, because the climate on the plateau is still different from our southern climate."

Everyone was surprised by Wang Bingbing's conclusion. They never expected that the test results would be so simple.

Only Feng Lanchu was not surprised, she smiled and took out her own information.

"The results of my report here are similar to those of Professor Wang. The pika is not the real culprit for the grass decline this time."

"What is that?" Wang Binbin was very interested when Feng Lanchu said that the result was the same as his.

"If there is no deviation in my investigation, then the main reason for the barren pasture this time is not natural disasters, but man-made disasters."

"Man-made disaster?" The administrator looked shocked, including Jiang Anzhi, Zhu Zhengkui, Cai Jiao, and others.

Feng Lan nodded calmly.

"After several days of investigation, I found that there are basically no wolves or birds where the villagers live. It sounds like it has nothing to do with pikas. In fact, these are the natural enemies of pikas. They hide deeper in the cave because they are afraid of humans. In places where pikas do not have natural enemies to control their numbers, they will naturally multiply wildly, which is the reason for the sudden surge of pikas.”

The reason for the surge of pikas has been found, but what is the reason for the decline of grasslands? This is not enough to dispel the suspicion of the pika! Everyone looked confused.

"Of course, it doesn't mean that the decline of grasslands has nothing to do with pikas. It's just a very small reason, and the main reason is the serious human damage, including the cattle and sheep raised by people."

"They consume a lot of pasture every day, and trample on the same area over and over again. Even if the regeneration ability is strong, it is impossible to supply it for such a long time."

"Just like what Professor Wang said just now, if people walk too much, it will become a road, and the pasture here is trampled by cattle and sheep, so naturally it doesn't grow very much. Perhaps the pasture here has shown signs of growth in the past year and the year before last. The state of weakness is just a little bit of change, and people don’t notice it. It’s only when the deterioration is serious that people discover it. It just so happens that pikas have been multiplying crazily in the past few years. When people find that the grassland is withered, they blame it on the pika.”

Everyone was shocked when they heard this conclusion. What can I do?

Feng Lanchu shook her head helplessly: "It is the best way to return the herds to forests."

But she doesn't suggest moving the whole village to a new place.

Because living in a new place for at most ten or eight years will be exhausted, and then there will be endless relocations.

That? How to return pastures to forests?
