How To Identify Good Caribou Migration Trails?

Researching Migration Patterns

When researching caribou migration patterns in Alaska, it’s essential to consult with local guides, hunters, or wildlife biologists who have extensive knowledge of the area. They can provide information on the species, subspecies, and specific migration routes. For example, the Western Arctic caribou herd migrates from wintering grounds in the Arctic coastal plain to summering grounds in the Brooks Range, passing through specific mountain passes and valleys.

Terrain Features and Habitat

Observe the terrain and note any areas with low-lying vegetation, rocky outcroppings, or narrow passes. These features often attract caribou as they provide shelter, protection from the elements, and access to food sources. Look for areas with willows, cotton grass, or lichens, as these are favorite foods of caribou. In Alaska, the caribou tend to migrate through areas with abundant willows and cotton grass, which are often found in wet meadows and river valleys.

Signs of Frequent Use

When searching for good caribou migration trails, look for signs of frequent use, such as hoof prints, scratched trees, and worn-down vegetation. Count the number of hoof prints and note the size and shape of the tracks. Check for any signs of recent use, such as fresh scat or tracks. In Alaska, caribou often travel in large herds, so look for areas with multiple sets of tracks or scat. Additionally, check for any signs of feeding, such as scratched bark or eaten vegetation.
