The European beaver was hunted to extinction for its fur, meat and the aromatic secretions from sacs near its anal glands. Now it is coming back throughout Europe , either naturally or by being introduced, as here in the UK. Wherever they settle they transform the landscape by building dams and channels and create a landscape of pools and watercourses that hold back flood water, pollution and silt from entering the main rivers. In these times of severe weather events and flooding beavers are doing for free what landscape engineers would do at great cost. Viewing nature in terms of the services it provides, or evaluating nature in financial terms, is a growing movement in conservation. Nature can be seen on balance sheets and hopefully respected for all that it gives us for free. But there is concern that monetising nature leaves it open to the ruthless world of finance and trading and diverts attention away from the real aims of conservation.

Albatrosses are giant flying seabirds that inhabit the southern oceans. Many species have been studied intensively over decades on their breeding grounds in the sub-Antarctic and the Pacific. Clever studies involving satellite tracking and simple observations from ships have shown they can disperse and forage across the whole of the southern ocean. Monitoring of their populations has shown a marked decline in their numbers since the 1980's so much so all albatross species are now threatened. A key cause of albatross decline was found quickly after the decline in populations was noticed; long-line fishing hooks baited with squid and floating on the surface after being deployed was an easy meal for an ocean scavenger and often their last. Shared Planet visits this story many years after it broke to report a cautious success on the high level conservation measures that were put in place involving biologists and the fishing industry.
