In the capital, new illegal buildings. They were accidentally discovered by the staff «Molodosti». Buildings erected on the island in Nagatinskaya valley, which was previously thought to be uninhabited. Ibid found other traces of life — fallen trees and food waste. The results of this survey, organized by «Mosvodokanal» that was sensational: in Moscow came beavers. A lot of them, they multiply rapidly and, judging by their tracks, mutate. In addition, it was found that they are dangerous and insidious.

Synthesis Papers on reacclimatization beaver in Russia IV gives Zharkov (1969, p. 10-51). He writes that in the late 20's - early 30's. this century beavers in the Soviet Union were a rarity. Work on artificial dispersal of these animals was started in 1934 (in Latvia - in 1927). In the first stage the only source of breeding material was Voronezh Reserve, from which from 1934 to 1947 exported more than 700 live beavers. In the second phase, starting in 1948, was used along with the Voronezh Belarusian native colony. Winter 1963/64, I. Zharkov said beginning of the third, the final Read more [...]
After checking local beavers (Samusenko, 1984) formed areas of land and water along the coastline, with numerous biological and abiotic differences between both the reservoir and the land. These sites - ecotones - after settling their beavers are exceptionally rich ecosystems that attract consumers of all ranks.
However, for such a big, strong, water and den fully protected animal the real enemy in the Latvian SSR can only be considered a wolf, and then only in the extensive forests of the lower reaches of the river. Abava and in the basin. Irbe, where the density of beaver is significant, Read more [...]
To solve the problems raised by us at the beginning of studies (see Introduction), required a detailed analysis of the geographical parameters of the study area. For this, as well as design data obtained in the study used the following mapping and other materials:
1) map of the Latvian SSR;
2) map drainage and land areas of the Latvian SSR for 26 sheets, made-Latgiprovodho Thus, M 1: 100 OOO;
3) maps of the Latvian SSR, M 1: 50 and 1 OOO 75 OOO;
4) tablets forest management scale 1: 10 000 and 1: 20 000;
5) taxation descriptions of the materials of forest management;
6) data of annual surveys Read more [...]

Beaver - A mammal rodent (Rodentia Bowdich), a family of beavers (Castoridae Gray) - belongs to the only genus in the family Castor L. Members of this family are inhabitants of forest ponds and narrow coastal strip in the temperate zone of the northern hemisphere. Age genus Castor is calculated from the Middle Miocene - about 15 million years old and the family Castoridae - from the Middle Oligocene, ie, a population of about 30 million years. During its existence the kind of growth fluctuated animals beavers were small, with modern marmot were gigantic.
However, the function of the beaver Read more [...]
The study of literature and research progress in the development of Beaver resources do not allow to doubt the necessity and the possibility of organizing a beaver management.
As for the reintroduction of beavers and further use of resources, there is an extremely wide variety of opinions, covering both fundamental approaches - to be or not to be beavers and Bobrova economy - and details, such as the issue of the number of licenses issued by the same hunter. There are different opinions about whether the required intensive form of such an economy, or rather regulate beaver population by catch Read more [...]
The main cause of the damage caused by beavers some sectors of the economy, the lack of timely information on the population of beavers undesirable from the point of view of human creation and a very rough idea of the number of animals. But it was not always so. There are reports that in the Middle Ages were able to pick up even herds suited beavers, predominantly black (data from A. Stanislavsky a manuscript in Latin on 1229 g - op. by-B. N. Scaloni, 1951). Probably in a similar state of the economy, the industry was in medieval Russia.

V. Dyakov (1975a) provides an overview of methods used in the Soviet Union to address livestock river otters. All existing methods he brings to four main: statistical, environmental, statistical, and for detecting Morphological and ecological capacity of settlements. According to the author, the statistical method is the most simple and gives a rough idea of the number of animals (Dyakov, 1975a, p. 339).
The essence of this method: in the first phase - to specify number settlements, on the second - using conversion factor to determine the number of animals in the study area (provided that Read more [...]
In 1980, the Ministry of Forestry and Forest Industries of the Latvian SSR received a number of applications of the damage to agriculture and forestry from the activities of beavers. The number of beavers republic at that time was estimated at 7,000 animals. The second half of the summer and autumn of 1980 has an exceptional abundance of precipitation and summer floods that made it very difficult objective assessment of the damage caused by beavers.

Throughout its existence, the beaver was a powerful edificator environment - active control of river flow (in their own "interests" and for the benefit of the ecosystem). Improving living conditions for all life, he made a significant contribution to the economy of nature. Centuries in the territories occupied for centuries beaver, man hunt for him, getting nutritious meat and skins for clothing, and for a long time, a unique remedy - castor. There was a time when the wealth derived from hunting beaver, affecting the economy and politics, and even a cause of war.

From the huge area occupied by Eurasian subspecies of modern beavers kind of Castor, the beginning of XX century there were only miserable, isolated pockets. No summarizing reports or map of the location of beaver colonies throughout its range. Existing information is inaccurate and even some controversy. The most detailed information Ognev S. (1947). Referring to the AV Fedyushin which, according to him, gave the most complete summary of beavers spread in Belarus, SI Ognev reports that otters remained on the upper course of the river.

Appraisal beaver land - water and coastal zone - was held in 1975 (890 units.) In 1976. (321 u). The results are reflected in the summary view the article numbered 3.21.
The table shows that the second site class received the vast majority (83%) of all bonitirovainyh sites, and if you select a particular type of "streams", ie, to exclude section 103, the ratio of yield classes becomes 4:87:9. On a scale V. Dyakova second site class has the largest range of scores - 8 (15 to 22), while the range of the third site class - 6 points (9 to 14), and the first - only 3 (23 25) points.

The oldest remains of Subfossil beaver bones in what is now the Latvian SSR are the seventh millennium BC, when the beaver is already reached a considerable size. Starting from the third millennium BC beaver here was an important hunting target, as evidenced by findings of beaver bones in archaeological excavations, where they often are the most common game animal bones - in the settlements "Kaulenkalns" and "Zvejnieki" respectively 66.1 and 59.3%.

In 1981, an intensive catch beaver traps. The results of the fishing catch by year and logging enterprises, as well as analysis of the intensity shown in catching watch Article numbered 3.31 and see article under the number 3.20. The table shows that the number of trapped beavers continuously grown and in season 1985/86 reached in 2788, and only 6 years old were caught about 6,300 individuals. Most shows steady growth catches Ventspils LPH, most spontaneous - Jurmala.

In the Saratov region, the largest beaver populations are confined to the floodplains of the rivers Volga, Khoper, Bear, Tereshka, B. and B. Irgiz Karaman. It also occurs in small bodies of water in all river basins Khoper, Dipper and the Volga.
