They make proteins and stocks: they dry mushrooms, impaling them on tree branches, bury acorns and nuts in pits. In case of crop failure of coniferous tree seeds, squirrels have been migrating since autumn, sometimes hundreds of kilometers from their native places.
The economic importance of mammals
The division of mammals, like other animals, into categories of harmful and useful is far from simple. The hare-hare nibbles the bark in young fruit orchards, carries pathogens of human diseases. But he is also an object of sport hunting, a source of meat and furs. The most valuable fur—bearing animal of the north, the Arctic fox, infects dogs with dangerous diseases. Wild boars are of commercial importance, sometimes they damage potato and grain fields, and therefore become harmful. Wolves remain the most dangerous predators in cattle breeding areas, i.e. almost everywhere where people live. It is very difficult to fight wolves, in particular because of the mobility of packs in winter. In recent years, the shooting of wolves has been carried out with the use of aviation and aerial sleds. The tiger can harm cattle breeding, but this animal, which has become rare, is listed in the Red Book and is protected everywhere. There are only a few indisputably harmful species that deserve to be destroyed in the conditions where they live. Most of them are rodents. First of all, these are synanthropic rodents living next to a person and at his expense. Rats and house mice bring great harm. The harm of synanthropic rodents is compounded by their ability to carry dangerous infections peculiar to humans. Most of the pests of field farming and horticulture belong to the mouse family. These are primarily various voles, among them especially the common vole and mice themselves. There are cases when these animals during the years of mass reproduction destroyed 80-90% of the grain crop on an area of tens of thousands of hectares. Voles mainly destroy plant seedlings, mice mostly destroy grain. In autumn, pests move from the fields to the stacks of unpolished bread, straw piles, haystacks and not only safely overwinter there, but often multiply in winter. In January 1943, in the Voronezh region, where there were unfilled stacks in the front line, when disassembling any of them, one and a half to two thousand gray voles and rodents of other species were found. There were a lot of pregnant women, newborns and young animals. Only in the stacks in which the weasels also settled (also breeding here), there were many gnawed and few living rodents. 1xBet promotion code is a unique code that allows players to accumulate additional points into their accounts in the form of a bonus.
