- El caribú de Grant (Rangifer tarandus granti) es una subespecie de caribú (Rangifer tarandus) encontrado en Alaska y partes adyacentes a Canadá. Se asemeja al R. t. groenlandicus y a veces se incluyen en una sola subespecie. Aunque los números varían, la manada está compuesta por más de 125 mil animales, que migran por 4.500 km cada año entre su gama de invierno y territorios de cría, la ruta de migración más larga de un mamífero terrestre. Son el sustento principal de los Kutchin, que tradicionalmente construyen sus comunidades sobre la base de los patrones de migración del caribú. También son habitualmente cazados por otros pueblos, incluyendo los , inuvialuit y . En la actualidad existe controversia sobre si es posible que la futura extracción de petróleo en las llanuras costeras del Refugio Nacional de Vida Silvestre del Ártico, que abarca gran parte de los territorios de cría del caribú de Grant, tenga un impacto negativo en la población.

- The Porcupine caribou (Rangifer tarandus groenlandicus) is a herd or ecotype of barren-ground caribou, the subspecies of the reindeer or caribou found in Alaska, United States, and Yukon and the Northwest Territories, Canada. A recent revision changes the Latin name; see Taxonomy. Migratory caribou herds are named after their calving grounds, in this case the Porcupine River, which runs through a large part of the range of the Porcupine herd. Though numbers fluctuate, the herd comprises about 218,000 animals (based on a July 2017 photocensus). They migrate over 1,500 mi (2,400 km) a year between their winter range and calving grounds at the Beaufort Sea, the longest land migration route of any land mammal on Earth. Their range spans the Alaska-Yukon border and is a valued resource cooperatively managed by the Alaska Department of Fish and Game, Canadian wildlife agencies and local aboriginal peoples. The caribou are the primary sustenance of the Gwichʼin, a First Nations/Alaska Native people, who traditionally built their communities to align with the caribou's migration patterns. They are also routinely hunted by other indigenous peoples, including the Inupiat, the Inuvialuit, the Hän and the Northern Tutchone. By July 2017, the Porcupine herd had reached a record high of about 202,000 to 235,000 animals. Sixteen years earlier, in 2001 the same herd was only half as large. While other barren-ground caribou herds have declined by 90%, the Porcupine herd has remained relatively stable. (en)
