What is japanese grass vole?

The Japanese grass vole, also known as the Japanese meadow vole or the Japanese red-backed vole, is a small rodent species found in Japan and nearby regions. They are typically 10-13 cm in length and 25-35 grams in weight, with short, dense fur that is reddish-brown on their back and lighter on their underside.

These voles are active throughout the year and prefer habitats such as grasslands, fields, and forest edges. They feed primarily on grasses and other vegetation, and are known to have a high reproductive rate, with females averaging 2-3 litters per year and up to 8 young per litter.

This species is not currently considered to be threatened or endangered, although habitat loss and fragmentation due to human activities may pose a threat to their populations in some areas. Japanese grass voles are important prey for owls, foxes, and other predators in their ecosystem.
