A beaver has been seen to the southeast of Loch Lomand in Scotland. The Loch is 36 km long and 1-8 km wide with its southern shores about 23 km northwest of the City of Glasgow. This is a significant sighting since it shows that beavers have made their way west from the River Tay, where beavers were illegally released 10 or more years ago and now number 400-600, via the extensive system of inland waterways including the Rivers Earn and Forth and their tributaries (The Sunday Post).
The Beaver Management Strategy Framework has been published “to help inform decisions regarding the long-term management of beavers, the wetland habitats they establish, and their general activities in the River Otter (Devon, England) in the future” . It can be viewed on the Devon Wildlife Trust web pages.
The Beaver Aquarium, a beaver breeding centre in Voronezh State Biosphere Nature Reserve, was set up in 1924 after hunting was prohibited by The Soviet government; at the time there were few beavers left in the wild. Beavers have been bred at the Aquarium and released since 1934, and now the population in southern Russia is estimated to be >700,000 (Euronews, Restexpert).
A pair of beavers were translocated to Cropton Forest near Pickering in North Yorkshire, England in April as part of a five year trial to see how their dam building would reduce flooding. Recent film shows that the pair have had two kits since their release (ITV News, BBC News, Yorkshire Post, Yahoo News).

Join us as we delve into the science, the story and the practical implications that surround the reintroduction of this once extinct animal to Great Britain. What do we need to know, what can we learn from others and where do we start?
Ben Goldfarb is an award-winning American environmental journalist whose 2018 book on beavers is a must read for all people interested in freshwater ponds, lakes, rivers and wetlands. The book elegantly makes the case as to why a world with beavers is far healthier both to humans and other wildlife than a world without them. Eager: The Surprising, Secret Life of Beavers and Why They Matter has won the 2019 Pen/EO Wilson Prize for Literary Science Writing.

Two beavers from Scotland have been released into a 10 ha enclosure in Cropton Forest in Yorkshire, England as part of a 5-year trial to assess the impact of their activity on flooding and biodiversity (see post of 27 september 2018) (BBC News, Flipboard, The Telegraph, ITV, Minster FM, Bridlington Free Press, Yorkshire Post).
A last-minute attempt by Conservative MSP John Scott to prevent beavers in Scotland attaining protective status was rejected by the Scottish Parliament’s Environment Committee yesterday (The Courier).
Following the post on 7th November 2018, a pair of beavers have now been released into a 4 ha enclosure on Spains Hall Estate in Finchingfield, Essex in the east of England to help prevent flooding. The estate is now owned by celebrity chef Jamie Oliver. The environment Agency will monitor flows in Finchingfield Brook that runs through the enclosure to see if the activities of the beavers improve water quality and help reduce the risk of flooding. They will compare the findings with more conventional flood prevention methods (BBC News, Braintree and Witham Times, Essex News, ITV News).
In a significant development, the Scottish Government have finally announced that they will introduce legislation to add beavers to the list of European protected species. As a consequence, any person wishing to control beavers (e.g. by shooting) will require a licence from Scottish Natural Heritage (SNH). The move, welcomed by many people and organisations but probably not all landowners or farmers (e.g. Farmers Weekly) , would also mean it would be an offence to to disturb beavers during the breeding season, as well as kill/injure any beaver. (Scottish Wildlife Trust, The Courier, Scottish Natural Heritage, Express & Star, BBC News, SPICe Spotlight, The National, Evening Express). Guidance on protected status mitigation by Chris Lindley can be found in The Courier (8 April).
Two beavers released into the Forest of Dean enclosure in the West of England last summer have been removed. They will be kept in quarantine and tested for the tapeworm parasite Echinococcus multicularis. This is a precautionary measure because other beavers imported into the UK from the same area in Bavaria where they originally came from are said to be infected with the parasite. The parasite has a life cycle involving a canid (e.g. fox, dog) definitive host which sits in the small intestines and delivers eggs in the droppings, and an intermediate rodent host which becomes infected by ingesting the eggs. These rodents may then be eaten by the canid, thus completing the life cycle. The concerns are that Echinococcus is not found naturally in the UK, and humans are at risk if they inadvertently ingest an egg, say from a dog who has eaten an infected rodent. It can cause an unpleasant, sometimes fatal disease. Although this is a set back for the project, it is hoped to release two new beavers soon that are known to be parasite free (Gloucestershire Live, Forest of Dean and Wye Valley Review).
