Bird or butterfly migrations cover extraordinary distances. For example, the butterfly Vanessa Cardui it runs 12,000 kilometers annually.
However, covering those flying distances does not have as much merit as doing it by land. And that context, the most meritorious case is the following, the longest land animal migration.
Grant's caribou (Rangifer tarandus granti) is the migratory land animal that stars the greatest distance traveled. Their herds cover up to 4,800 kilometers a year, on the way to territories where to spend the winter sheltered. This species is found in Alaska, the United States and Yukon.
They are the mainstay of the Kutchin, who traditionally build their communities on the basis of caribou migration patterns. They are also usually hunted by other peoples, including the Inupiat, Inuvialuit and Han.
The Alaska Department of Fisheries and Hunting, Canadian wildlife agencies and local Aboriginal peoples cooperatively manage the pack. The advisory board of the Porcupine Caribou Management Board (PCMB) was established under the Porcupine Caribou Administration Agreement in 1985
