Meet the Wood Mouse

Wood mice are one of the UK’s most widespread small mammals and can be found in woodland, hedgerows, gardens and farmland. Recognisable by their large ears, dark eyes and long tails, they are skilled climbers and impressive jumpers for their size.

🌰 Nature’s Seed Planters

Wood mice help spread seeds and nuts by burying food stores, many of which are never recovered and later grow into plants.

🌙 Mostly Nocturnal

Wood mice are most active after dark, using their excellent hearing and sense of smell to avoid predators.

🦉 Vital Food Source

They are an important part of the food chain and provide food for owls, foxes, kestrels, stoats and other native predators.

🏃 Tiny but Agile

Wood mice can leap surprisingly high and use their long tails for balance while climbing through vegetation.

How You Can Help Wood Mice

Small mammals face many challenges in gardens and urban spaces, but simple changes can make a huge difference.

Avoid glue traps and poisons, which can cause prolonged suffering to wildlife.

Keep natural areas in gardens, including hedges, long grass and log piles for shelter.

Check carefully before strimming or mowing overgrown areas.

Keep cats indoors at night where possible, particularly during breeding season.

Leave wild corners to support insects, seeds and natural food sources.
