Leaf River

  • Range: 663,810 km2
  • Herd size (2025): 136,000, a drop from 175,000 in 2024, and over 600,000 in the early 2000s. 

The migration of the Leaf River subpopulation is approximately 1000 km, one of the longest known for caribou. The herd moves between the southwest and northeast of the Ungava Peninsula in Nunavik (northern Quebec) in the spring and fall.

A thriving sport-hunting business was once attached to this herd, but the sport hunt ended in 2018. The herd was also hunted commercially between 1994 and 2002.

Inuit communities have suggested that muskoxen displace the caribou from some sectors.

The Quebec government has attempted to protect the calving area of the herd with a legal designation that prohibits any human activity that may negatively affect caribou habitat between May 15th and July 15th. However, the area protected does not always coincide with the area being used for calving.

Th Grand Council of the Crees has posted information on its website that says, "Habitat disturbance and the 2023 wildfires have significantly impacted caribou habitat in Nunavik and Eeyou Istchee, exacerbating the effects of hydroelectric reservoirs and reducing winter range quality and availability. Since 2018, the Leaf River herd has shifted its winter range further south, with the 2023-2024 range extending southeast beyond previously recorded locations. "

Hunting of the herd by Innu was voluntarily halted in 2025. Most hunting of the herd is done by Cree communities in Quebec. In early 2026, the Cree Nation Government called for a pause on all hunting of the herd.

It includes new estimates of the herd size (down to 155,00). It says flooding from hydro developments, widlfires, and industrial impacts have degraded the food available in the herd's range, and have resulted in shifting migration patterns. It notes voluntary reduction in harvest by Cree and Innu communities, and calls for reliable harvest monitoring.

Morphological Traits Are Not Consistently Related to Population Size in Four Migratory Caribou Populations Across North America

Can physical appearances of caribou be used to infer population health? That was a question asked by authors of this academic paper who looked at body mass, body fat, and hind foot length in four caribou herds (Porcupine, Beverly, Leaf River and George River) and tried to see if there was a connection between those indicators and herd size or trend. The paper found that those physical indicators were not sufficient to accurately assess herd numbers or trends.
