By working together, Alaska CASC researchers confirm avalanches are a major contributor to mountain goat fatalities

A study by Alaska Climate Adaptation Science Center scientists revealed that mountain goats in Southeast Alaska may be at higher risk for mortality as they are pushed deeper into avalanche terrain.

Research connections reveal risks to mountain goats from avalanches in Southeast Alaska

By Mike Delue | May 7, 2024
A white mountain goat looks out at the land while standing on a ledge of a snowy, rocky mountain.

Mountain goats are highly specialized for alpine life but survival requires negotiating precarious trade-offs. Findings from a long-term study by AK CASC researchers show that death from avalanches represents a widespread but previously undescribed pathway by which snow can influence populations of these mountain-adapted animals.
