New Atlas Helps Remove Barriers to Animal Migration in Central Asia
The UN Convention on Migratory Species (CMS) has launched the Central Asian Mammals Migration and Linear Infrastructure Atlas to help ensure the survival of migratory wildlife in this important region.
Featured in the Atlas are the Asiatic Cheetah, the Snow Leopard, as well as antelopes, deer, gazelles, wild horses and yaks which undertake long-distance journeys across the steppes, deserts and mountains of Central Asia to reach their feeding and breeding grounds. They depend on interconnected landscapes for their well-being and ultimately their survival.
However, the grasslands and deserts of Central Asia are increasingly being fragmented and even destroyed. Railways, fences and pipelines cut though open landscapes thereby constituting an often unsurmountable barrier to animal movement – with adverse effects on their chances of survival.
The Atlas has been launched in the run-up to the 13th meeting of the Conference of the Parties to CMS (COP13) to be held in India 15- 22 February 2020. Ecological connectivity will be a core theme of COP13. To save nature in an increasingly fragmented world, the concept of connectivity needs to be incorporated in conservation efforts at all levels, from global to local.
The Atlas contributes to this: In addition to showing where animals migrate, the Atlas depicts linear infrastructure such as fences, railways, roads or pipelines that can interfere with the free movement of endangered populations of large wide-ranging animals.
The information on the distribution and movements of migratory animals will help decision-makers to plan and implement infrastructure projects to make them migratory wildlife friendly or, for infrastructure already in place, retrofit them to mitigate or eliminate their barrier effect.
The dramatic increase of railways, roads, pipelines and canals are a major threat to migratory animals. These barriers to migration fragment wildlife habitat, isolate populations and prevent access to forage and water. Many animals suffer lethal injuries in the attempt to cross these barriers.
The impact of linear infrastructures as barriers to migration cumulates with other threats affecting migratory species in Central Asia. Human settlements encroach into wildlife habitat and cause competition for pasture with growing livestock herds. Poaching for fur, horns, meat or illegal trade of other body parts of endangered species are building up even more pressure — and the global phenomenon of climate change threatens to destroy the quality and functionality of wildlife habitats.
