How many litters per year and typical litter size do voles have?

Explanation:
Voles reproduce quickly, allowing their populations to grow rapidly when conditions are favorable. They have multiple litters each year, and each litter contains a relatively small to moderate number of offspring. The combination of several litters annually and about 3–6 young per litter fits what is typically observed for voles in field situations. This pattern explains why vole populations can rebound quickly after declines. While some species may vary a bit, the range of 1–5 litters per year with 3–6 young per litter best matches their general reproductive strategy.
