Barents Sea ecoregion conservation priority areas Barents Sea ecoregion conservation priority areas
The Barents Sea ecoregion - the part of the World Ocean north of the Nordic countries and Northwest Russia, has a unique environment with major sea bird colonies, rich benthic and plankton fauna and many major sea mammal species. To identify priority areas for conservation, thirty experts delineated sea areas based on ecological criteria in a WWF study.

Major global bird migration routes to the Arctic Major global bird migration routes to the Arctic
Bird species that migrate to the Arctic coasts and wetlands arrive from nearly every corner of the planet. During the summer, the sun never or nearly never sets, resulting in a short but intensive breeding season when millions of migratory birds arrive in the Arctic to breed. The majority of these birds seek the wetlands and coastal shores of the tundra plains. No other place on Earth receives so many migratory species from nearly all corners of...

Protected areas in the Barents ecoregion Protected areas in the Barents ecoregion
The Barents Sea ecoregion - the part of the World Ocean north of the Nordic countries and Northwest Russia, has a unique environment with major sea bird colonies, rich benthic and plankton fauna and many major sea mammal species. Within this ecoregion, this graphic illustrates the existing coverage of protected areas. One of the main threats to the region is the development associated with the expansion of fossil fuel extraction activities. Russi...

A photographic impression of the gradual changes in two ecosystem types A photographic impression of the gradual changes in two ecosystem types
Globally, over 1,000 (87%) of a total of 1,226 threatened bird species are impacted by agriculture. More than 70 species are affected by agricultural pollution, 27 of them seriously. Europe’s farmland birds have declined by 48% in the past 26 years (European Bird Census Council, 2008). Pesticides and herbicides pose a threat to 37 threatened bird species globally (BirdLife, 2008), in addition to deleterious effects of agricultural chemica...

Distribution of common eider, breeding and wintering ranges in the Arctic Distribution of common eider, breeding and wintering ranges in the Arctic
The common eider, Somateria mollissima, has a circumpolar distribution breeding mainly on small islands in Arctic and boreal marine areas in Alaska (Bering Sea region), Canada, Greenland, Iceland, western Europe, and the Barents Sea region. In Russia, there is a gap in distribution along the mainland coast from the Yugorski Peninsula (Kara Sea) to Chaunskaya Bay in east Siberia (Figure 5.1). Important wintering areas include the Gulf of Alaska/Be...

Oil and gas development and seabirds colonies in the Barents Region Oil and gas development and seabirds colonies in the Barents Region
The Barents region is a highly explored area for gas and oil. The corresponding areas of oil exploration and sea bird colony proximity are clearly shown on the map. The disputed area between Norway and Russia is also highlighted. (Please note that the The Barents Euro-Arctic Council has expanded the membership since 1998)

Biodiversity threats Biodiversity threats
South Africa is recognised as the third most megadiverse country in the world. The abundance of biodiversity found within its borders covers an estimated ten per cent of the world’s plant species, seven per cent of all bird, six per cent of all mammal, and five per cent of all reptile species found on the planet. Due to various causes ranging from unsustainable land use and farming practices, to invasion by alien species and climate change, So...

Global flyways of the six subspecies of Red Knot Global flyways of the six subspecies of Red Knot
The Red Knot is a migratory shorebird that travels up to 20,000 km twice a year from its breeding grounds on the high Arctic tundra to its southern non-breeding sites. Along with having one of the longest total migrations of any bird, some populations also fly as much as 8,000–9,000 km between stopover sites in a single flight. As a shellfish-eating specialist avoiding pathogen-rich freshwater habitats, the Red Knot relies on the few large ti...

Migration of grassland birds in America Migration of grassland birds in America
The grasslands of Argentina, Bolivia, Brazil, Paraguay, and Uruguay in southern South America represent important habitat to numerous migratory and resident bird species. These birds play vital roles in the ecosystem by dispersing seeds and controlling insect populations. Some species, such as the Buff-breasted Sandpiper (Tryngites subruficollis), migrate some 20,000 km from their breeding grounds along the Arctic coast to their non-breeding rang...
