Lifespan
The European pine marten has lived to 18 years in captivity, but in the wild a lifespan of eight to ten years is more typical. They reach sexual maturity at two or three years of age. The young are usually born in March or April after a 7 month-long gestation period in litters of one to five. Young European pine martens weigh around 30 grams at birth. The young begin to emerge out of their dens by the middle of June and are fully independent around six months after their birth.
