How long squirrels live depends on surviving their first year
This article explores the factors influencing the lifespan of various squirrel species, emphasizing that survival during the first year is the most critical determinant. It notes that while environmental conditions and predator avoidance play significant roles, most squirrels have relatively short lifespans in the wild.
Why it matters
Understanding wildlife mortality rates helps in ecological conservation efforts and provides insight into the natural life cycles of common urban animals.
Squirrels are some of the commonest animals in parks, gardens and backyards. You might see them scuttling across a fence or racing up a tree trunk or digging through leaves for food. They are quick, clever and endlessly busy, which is probably why so many people wonder how long they actually live.The answer is not the same for every squirrel.The lifespan of a squirrel depends on the species of squirrel, its environment and its ability to avoid predators, disease and human hazards.Some squirrels may only live a few years in the wild, while others can survive much longer if conditions are safe.Typical squirrel lifespansAmong the most common species, the eastern gray squirrel usually lives around six years in the wild. In especially favourable conditions, with steady access to food, water and shelter, some have been known to reach 12 years.
