Red deer in the Scottish Highlands face severe welfare impacts from winter food scarcity, particularly when high population density combined with harsh conditions leads to starvation of calves and weak adults.
Winter starvation in deer causes progressive suffering over days to weeks, beginning with visible weight loss, weakness, and eventually inability to stand or move. Calves that fail to accumulate sufficient fat reserves before winter are at highest risk. Welfare impacts are compounded on estates where culling levels are insufficient to maintain populations within carrying capacity, creating predictable annual starvation events.
