Leaf River (Quebec)

Leaf River (French: Rivière aux Feuilles; Inuktitut: Kuugaaluk ["the large river"] or Itinniq ["where there are spring tides"]^[2]) is a river in northern Quebec, Canada, at the northern limit of the tree line. It flows from Lake Minto northeast through the Ungava Peninsula into Leaf Bay off Ungava Bay over a distance of 480 kilometres (300 mi).^[3] At the head of Leaf Bay is the Inuit community of Tasiujaq.

With caution, it is possible to paddle the entire Leaf River without portaging, as it contains no impassable waterfalls or non-navigable rapids.^[4][5][6][7] The river's length, measured from Charpentier Bay to Tasiujaq, is 320 kilometres (200 mi); if measured from first discernable current, it is 288 kilometres (179 mi).^[8]

The river is ice-free for about 60 days each year.^[2]

The significant tributaries of the Leaf River are:^[8]

• Charpentier River^[4][6]
• Nedlouc River
• Descareaux River
• Daunais River
• Goudalie River
• Vizien River^[5]
• Brissard River
• Qijuttuuk River
• Cohade River
• Tuktu River
• Dufreboy Creek
• Viennaux River
• Papijjusaq River
• Peladeau River
• Fanfan River

Since at least the late 19th century, the river has been known by its English name, "Leaf River", which was probably derived from the Arctic willow and birch trees that grow sparsely along its banks.^[2] The Hudson's Bay Company fished there for salmon and porpoises, and opened a trading post at the mouth of the river around 1905. In the early 20th century, the French name Rivière des Feuilles was assigned, and standardized to its current form Rivière aux Feuilles in 1925.^[3]

La manada de caribúes de Leaf River (LRCH) ^{[ 10 ]} es un ecotipo migratorio de bosque-tundra de la población boreal , una subespecie de caribú de Rangifer tarandus. Al igual que la manada de George River , migra entre el bosque y la tundra. Las manadas de caribúes migratorias a menudo se definen en términos de filopatría natal de las hembras o regreso al lugar de nacimiento , la tendencia a regresar a las áreas de cría natales, en este caso, Leaf River. La manada de Leaf en el oeste, cerca de la costa de la bahía de Hudson , aumentó de 270.000 en 1991 a 628.000 en 2001. ^{[ 11 ]} Según el estudio de Recursos Naturales y Vida Silvestre de Quebec, la manada de Leaf River (LRH) (Rivière-aux-Feuilles) había disminuido a 430.000 caribúes en 2011. ^{[ 12 ] [ 13 ]} Según un estudio internacional sobre poblaciones de caribúes, la manada de Leaf River podría estar amenazada de extinción para 2080. ^{[ 14 ]}
