The Qinghai Tibet Plateau pika is flooded, with a population of up to 1.2 billion, and the herders h

Pika digging can play a role in improving the soil, in the process of pika digging can play a role in turning over the soil, the soft soil will be brought to the surface, which is equivalent to human planting crops before plowing and raking, for the germination and growth of plants to provide certain conditions. In addition, pikas are natural "toilet spots", and these droppings can provide nutrients to plants, nourish plants, and increase the production of native plants.

The pika has a particularly strong reproductive ability, and there are many carnivores on the plateau, and these pikas can protect the ecological environment of the plateau.

The main reason is that this pika can not only play a role in improving the soil, but also their manure can provide more nutrients for plants, nourish plants, increase the production of native plants, can conserve water, play an auxiliary role in soil development and ventilation and mixing, can provide more shelter for other small animals, and this animal is also the main predator of other small and medium-sized carnivores and almost all birds of prey. The abundance of this animal may have a very good balance for the local ecology.

Because plateau pikas maintain the biodiversity and ecosystem balance of the Tibetan Plateau, protecting them is tantamount to maintaining the ecological environment.

This is because this rabbit is particularly capable of reproducing, and the number of kills is far less than the number of births, so it will continue to reproduce.

It is because this rabbit reproduces very quickly, sometimes it can rise more than 20 in a litter, and no natural enemies of this rabbit have been found so far.

In fact, this kind of thing has a very high fecundity, and there are immune cells in the body, which can block some pesticides to make them produce antibodies, this kind of thing is annoying.

<> "Why the flooded plateau pika is said to be a good thing."

First of all, the plateau pika, as a burrowing creature, is able to make the land of the Qinghai-Tibet Plateau more relaxed and fertile. In the Tibetan Plateau, because the temperature is low and there is little vegetation, the fertility of the soil is not very high, and the growth rate and quality of the grassland are not very good.

Later, as scientists conducted in-depth research on the plateau pika, they found that the plateau pika, as the bottom of the food chain, mainly feeds on the weeds and poisonous weeds of the Qinghai-Tibet Plateau, and can feed on many poisonous pastures.

At the same time, it can also change the structure and composition of the soil by drilling holes, which can also allow the soil to absorb more water and nutrients, and can also accelerate the decomposition of the original substances in the soil and improve the fertility of the soil. Moreover, the burrow excavation of the plateau pika is also unique, and a special water storage area is built, which can not only meet the daily water consumption of the plateau pika, but also play the role of moistening the land.

Secondly, the plateau pika does not hibernate in winter and continues to go out to hunt, which can provide food for many large animals that are difficult to catch food in winter. The highland pika still has to go out to fetch food in the winter, which provides food for the winter season**. Snow leopards, Tibetan foxes and even eagles feed on plateau pikas to survive the long, cold winters of the Tibetan Plateau.

At the same time, the abandoned burrows of the highland pikas have become a new home for many birds and amphibians. Due to the scarcity of trees in the Qinghai-Tibet Plateau, many birds are unable to settle in the trees, so they can only seek out the abandoned burrows of the plateau pikas as temporary shelters, while many amphibians also take shelter from the wind, snow and cold in the burrows of the plateau pikas.

It can be said that the plateau pika was responsible for the degradation of the pastures in the past, and suffered from the ruthless extermination of humans, which severely reduced its population. Later, as humans had a new understanding of the plateau pika, it was discovered that the 1.2 billion plateau pikas on the Qinghai-Tibet Plateau are really a rare wealth, which can not only improve the local soil environment, improve the quality of grasslands, but also provide food and habitat for other animals.

In the alpine meadows and alpine grasslands of the Qinghai-Tibet Plateau, the weak plateau pika has established an interdependent relationship with a large number of animals and plants due to its habit of digging holes and building nests. The plateau pika is a unique ecosystem built by its neighbors on the Tibetan Plateau.

The plateau pika is an endemic and key species of the Tibetan Plateau, which plays an important role in maintaining the biodiversity and ecosystem balance of the Tibetan Plateau. The burrows it digs were meant to escape the cold climate and predators, but they provide nests for many small birds and lizards; disturbance of microhabitats and increased plant diversity; At the same time, the plateau pika is also the main predator of most small and medium-sized carnivores and almost all birds of prey in the grassland. The burrows of the highland pika are "natural toilet places" that nourish the plants and provide conditions for the diversity of plant species.

Plateau pika: endemic to the Qinghai-Tibet Plateau, misunderstood and regarded as a "pest".

1) Plateau (and grassland).

2) Call the pattern of the grass, the pika, the wolf (or others).

3) Canines 4) Congenital.

6) Pikas can loosen the soil, and the manure can increase the nitrogen, phosphorus and potassium content of the soil, thereby promoting the vigorous growth of grass.

The plateau pika has always been regarded as a harmful animal by many people. They believe that pikas compete with domestic animals for pasture, or that its activities have led to the degradation of alpine meadows. They release or spray toxic substances over vast areas of the Tibetan Plateau in order to reduce the damage caused by pikas to the vegetation and pastures of the plateau.

In fact, in areas where pikas have reached a higher density, the grass has long been eaten by other animals such as cattle and sheep, but people mistakenly believe that the decaying land they see is caused by pikas. In fact, on the contrary, pikas are a warning sign of damaged land: there are pikas, and there are all kinds of interesting animals and plants that live and grow in that particular area; If the pika is killed, the natural scenery will lose its vitality and color.

Some parts of China** have been trying to eradicate pikas since 1958, when poisoning programs were approved for the first time. In 2006, nearly 360,000 square kilometres of poison were reported in Qinghai province alone. ** Later, a huge amount of money was allocated to carry out a new phase of poisoning, costing about $35 million.

The spread of these poisons and the ripples of the pika's strangulation will even reach the next generation of Chinese people, who may no longer have the opportunity to see the world's most unique ecosystem.
