Researchers have documented the longest-known African animal migration. 

Zebras cover about 300 miles of African terrain during their migration, a World Wildlife Fund (WWF) news release reported.

The researchers attached eight GPS collars to adult plains zebras and tracked their movement between Chobe River in Namibia and Botswana's Nxai Pan National Park for two years. This is a 500 kilometer (about 310 mile) journey round-trip.

The great zebra migration has been disturbed by human activity, such as fences, throughout the years. 

"This unexpected discovery of endurance in an age dominated by humans, where we think we know most everything about the natural world, underscores the importance of continued science and research for conservation" Doctor Robin Naidoo, senior conservation scientist at WWF, said in the news release. 

This new research could help aid in zebra conservation efforts.

 The migration takes place without using the Kavango Zambezi Transfrontier Conservation Area (KAZA), which is the "the world's largest multi-country conservation area," the news release reported. The region spans 109 million acres across "Namibia, Botswana, Zimbabwe, Zambia and Angola," the news release reported. This area could be key in protecting the future of mammal land migrations. 

"The findings of this study emphasize the importance of trans-frontier conservation areas in conservation of the greater landscape" Pierre Du Preez, Chief Conservation Scientist at MET in Namibia, said in the news release. "This study has played a crucial role in helping determine a key wildlife corridor in KAZA."

"At a time when conservation news is inherently rather negative, the discovery of this unknown natural phenomenon should resonate with people around the world. The government's commitment to secure key migratory corridors serves to underpin the growing wildlife tourism industry. We plan to continue monitoring the migration to try and conserve such increasingly rare natural events,"  Doctor Mike Chase, EWB's founder, said in the news release.
