The harvest mouse (also known as the Old World harvest mouse) is the smallest rodent found in the continent of Europe, living in tall grass fields and crop fields.

They are the only mammals in Great Britain with a tail that offers prehensility, allowing them to grab hold of stalks and stems in the tall grasses they live in.

They can be found extensively all over Europe and Asia, being a very common sight in some urban localities and among grasses scattered across the two continents.

They are one of the more common members of wildlife in some parts of England and the rest of Europe, however, with the advent of agricultural technology and rapid urbanization, the distribution of these tiny mammals has been affected and their populations have sadly been decreasing throughout the decades.

These mice have are unlikely to enter and cause havoc in urban settlements and houses as they are known to keep to themselves in farmlands and forests. They generally feed on seeds and cereal heads and are not known for stealing food from households.

Are harvest mice endangered?

They are quite common in many localities and are not endangered per se, however, they have been decreasing in numbers throughout the years in the UK and across some Asian countries.

For instance, in Japan, the distribution of harvest mice is being threatened by various factors which are anthropogenic in nature.

Some of the root causes for the decrease in the number of harvest mice across Japan and in other countries are the excessive use of and insecticides and pesticides, urbanization, commercial farming, and the destruction of wetlands. Forests and grasslands across Eurasian countries are rapidly being destroyed, having a direct effect on this species and the wildlife around them.

A survey has determined that the nests of this species are on a steady decline as more than 85% of their habitat is becoming uninhabitable for them.

Since 2019, the government of the UK has called for the protection of this species under the United Kingdom Post-2010 Biodiversity Framework and the Wildlife and Countryside Act of 1981.

Are harvest mice pollinators?
