First-ever global initiative to map mammal migrations
An international team of 92 scientists and conservationists has joined forces to create the first-ever global atlas of ungulate (hooved mammal) migrations, working in partnership with the Convention on the Conservation of Migratory Species of Wild Animals (CMS), a UN treaty.
The detailed maps of the seasonal movements of herds worldwide will help governments, indigenous people and local communities, planners, and wildlife managers to identify current and future threats to migrations, and advance conservation measures to sustain them in the face of an expanding human footprint.
The Global Initiative on Ungulate Migration (GIUM) was launched with the publication of a commentary titled "Mapping out a future for ungulate migrations," in the May 7 issue of the journal Science.
"A global migration atlas is urgently needed because there has never been a worldwide inventory of these phenomenal seasonal movements," said lead author Matthew Kauffman, a wildlife biologist with the US Geological Survey. "As landscapes become more difficult to traverse, the maps can help conservationists pinpoint threats, identify stakeholders, and work together to find solutions."
Year after year, migratory ungulates must pound their hooves across vast areas of the planet to find food, escape harsh conditions, and breed. The movements are as diverse as the species themselves, which include Mongolian Gazelles and Saiga in Asia, wildebeest in the Serengeti, Guanacos in South America, Arctic Caribou and wild Reindeer, Mule Deer and Elk in North America, Red Deer in Europe, and many more.
Migratory ungulates are an essential part of natural ecosystems and provide much of the prey for the world's carnivores. The migrations also contribute to local and regional economies through harvest and tourism, and are woven into the culture of numerous communities. Unfortunately, many ungulate migrations are in steep decline due to human disturbances like roads, fences, and other types of development.
