“…An isolated population of Belarusian origin has existed in the Amur basin near Khabarovsk for 55 years; population and range are increasing. In contrast, the nearby population of Castor canadensis on the Obor is in decline (Oleinikov 2013).…”

A century ago, overhunting had reduced Eurasian beaver Castor fiber populations to c. 1200 animals in scattered refugia from France to Mongolia. Reintroductions and natural spread have since restored the species to large areas of its original range. Population has more than tripled since the first modern estimate in 1998; the minimum estimate is now c. 1.5 million. Range expansion 2000–2020 has been rapid, with large extensions in western and south‐central Europe, southern Russia, and west and central Siberia. Beavers are now re‐established in all countries of their former European range except for Portugal, Italy, and the southern Balkans; they occur broadly across Siberia to Mongolia, with scattered populations father east. About half of the world population lives in Russia. Populations appear to be mature in much of European Russia, Belarus, the Baltic States, and Poland. There is a significant population of North American beaver Castor canadensis in Finland and north‐west Russia. Most other 20th‐Century introductions of this species have become extinct or been removed. Recent DNA studies have improved understanding of Castor fiber population prehistory and history. Two clades, east and west, are extant; a third ‘Danube’ clade is extinct. Refugial populations were strongly bottlenecked, with loss of genetic diversity through genetic drift. Future range extension, and large increases in populations and in impacts on freshwater systems, can be expected. Beavers are now recolonising densely populated, intensely modified, low‐relief regions, such as England, the Netherlands, Belgium, and north‐west Germany. They will become much more common and widespread there in coming decades. As beavers are ecosystem engineers with profound effects on riparian habitats, attention to integrating beaver management into these landscapes using experience gained in other areas – before the rapid increase in population densities and impacts occurs – is recommended.

“…For the whole of Russia recent records refer only to the capture of single individuals or to local populations consisting of some tens of individuals (Skumatov and Saveljev 2006). American mink is present from the far East to the West of Russia, and it is also spreading towards the south, recently recorded also in the in the territory of the Uvs Nuur Hollownorth of Mongolia (Oleinikov. 2013, Saveljev et al 2015.…”

“…The species is native to the North America: its natural range extends from Alaska and Canada through most of United States, except a few southern regions as California, Nevada, Arizona, Utah, New-Mexico and West-Texas (Dunstone, 1993, Larivière 1999. Outside the native range, and besides Europe, the American mink has also been introduced to South America (and is currently present in Chile and Argentina, ranging as far south as Tierra del Fuego and Navarino Island) and Asia (Russia, Mongolia, Japan) (Heptner et al 1967, Previtali 1998, Bobrov et al 2008, Shimatani et al 2008, Ibarra et al 2009, Fasola et al 2011, Schüttler, et al 2010, Oleinikov A.

The distribution of the American mink in the wild, originating either from accidental escapes or intentional releases from fur farms, was mapped for the first time in Greece, based on opportunistic data collected from 2010 to 2020. Greece is a key actor in Europe’s fur industry, with most mink farms operating in the northwest. Massive intentional releases by activists took place in the late 2000s, while accidental escapes regularly occur. Most mink were recorded in the Region of Western Macedonia, in NW Greece, within and around the core areas of fur farms, where feral populations became established. Animals were also found further south in the Regions of Thessaly (central Greece) and Central Macedonia (northern Greece). Half of mink records were close to protected areas and almost two-thirds near to watercourses. Many animals were away from the water and on high altitudes, with theoretically less favourable conditions for their survival. We also examine possible directions of further mink range expansion in Greece and neighbouring countries through the river network. Mink invasion progress in Greece is little known, thus, the subject is in urgent need of study, as mink is the alien mammal with the highest impact on the European native fauna.

“…There is no data on current numbers of North American beavers in Kamchatka and their relations with bears. The study of the interspecific peculiarities of behaviour of beavers in the contact areas and their relations with local fauna, needs to be done (Oleynikov, 2013).…”
